Dyeing Dyeing is the process of adding color to textile products like fibers, yarns, and fabrics. Dyeing is

normally done in a special solution containing dyes and particular chemical material. After dyeing, dye

molecules have uncut chemical bond with fiber molecules. The temperature and time controlling are

two key factors in dyeing. There are mainly two classes of dye, natural and man-made.

Methods Dyes are applied to textile goods by dyeing from dye solutions and by printing from dye pastes.

Methods include direct application and yarn dyeing.

Direct application The term "direct dye application" stems from some dyestuff having to be either fermented as in the

case of some natural dye or chemically reduced as in the case of synthetic vat and sulfur dyes before

being applied. This renders the dye soluble so that it can be absorbed by the fiber since the insoluble

dye has very little substantivity to the fiber. Direct dyes, a class of dyes largely for dyeing cotton, are

water soluble and can be applied directly to the fiber from an aqueous solution. Most other classes of

synthetic dye, other than vat and surface dyes, are also applied in this way.

The term may also be applied to dyeing without the use of mordents to fix the dye once it is applied.

Mordents were often required to alter the hue and intensity of natural dyes and improve color

fastness. Chromium salts were until recently extensively used in dying wool with synthetic mordant

dyes. These were used for economical high color fastness dark shades such as black and navy.

Environmental concerns have now restricted their use, and they have been replaced with reactive and

metal complex dyes that do not require mordant.

Yarn dyeing There are many forms of yarn dyeing. Common forms are the package form and the hanks form.

Cotton yarns are mostly dyed at package form, and acrylic or wool yarn are dyed at hank form. In the

continuous filament industry, polyester or polyamide yarns are always dyed at package form, while

viscose rayon yarns are partly dyed at hank form because of technology.

The common dyeing process of cotton yarn with reactive dyes at package form is as follows:

The raw yarn is wound on a spring tube to achieve a package suitable for dye penetration.

These softened packages are loaded on a dyeing carrier's spindle one on another.

The packages are pressed up to a desired height to achieve suitable density of packing.

The carrier is loaded on the dyeing machine and the yarn is dyed.

After dyeing, the packages are unloaded from the carrier into a trolley.

Now the trolley is taken to hydro extractor where water is removed.

The packages are hydro extracted to remove the maximum amount of water leaving the

desired color into raw yarn.

The packages are then dried to achieve the final dyed package.

After this process, the dyed yarn packages are packed and delivered.

Modern Tie-dye There are many traditional variations of Tie-dye around the world, including Shibori and Ikat. We

consider modern tie-dye to be an American art form! Each type is unique, but basically Tie-dye is a

way of creating patterns of color by folding, tying, stitching, crumpling or otherwise preparing the

fabric to inhibit the flow of the dye into the folds of the fabric. The pattern of the folds and where the

colors are squirted determines the final design. With experience, the end result can be predicted and

controlled to some extent, but surprise is part of what makes tie-dye an exciting and interesting art

form that even a first timer can have great results with. A fun & easy craft for children, camps and

groups.

Step 1: fold and tie your garment Step 2: soak garments in soda ash

solution

Step 3: mix your dyes Step 4: squirt on your dye

Step 5: let it rest Step 6: wash it out

Shibori: Shibori is a Japanese term for methods of dyeing cloth by binding, stitching, folding, twisting, and

compressing. In Japan, the earliest known example of cloth dyed with the shibori technique dates back

to the 8th century where indigo was the main dye used. We were immediately inspired by this

fascinating technique, its history and beauty. After much research, we decided to tackle 3 techniques

of Shibori dyeing with an Indigo Tie Dye Kit, a few old white shirts and scarves, and several household

items.

Arashi (Japanese for “storm”) shibori a pole-wrapping technique. The cloth is wrapped on a diagonal around

a pole or cylindrical object (we used old PVC and copper piping) and then tightly bound by wrapping

thread or wire up and down the pole. Next, the cloth is scrunched down on the pole. The patterns are

on a diagonal in arashi shibori which suggests the rain from a heavy storm.

Kumo This is a twist and bind resist technique. This technique involves wrapping sections of the cloth over a

found object, usually small stones or pebbles. Then the cloth is bound in very close sections with

rubber bands. The result is a very specific circular spider-like design.

Itajime This is a shape-resist technique. The cloth is folded like an accordion and sandwiched between two

pieces of wood or any flat shaped object, which are held in place with string or rubber bands. The

shapes prevent the dye from penetrating the fabric they cover and give an endless variety of patterns

depending on the fold, binding object and placement of rubber bands.

We’re ready to dye

Following the dye preparation directions from the Indigo Tie Dye Kit were easy; first rinse your fabric

with water, dip in the indigo vat that was premixed before binding the fabric, let it oxidize and dry for

20 minutes and then repeat the steps for darker shades of indigo. Be aware that the color is much

darker when wet and will fade after rinsing.

Rinse the fabric with water and undo the bindings to reveal the surprising creations.

Our patterns revealed: Arashi, Kumo and Itajime. The possibilities are endless–try varying and even

combining the techniques to see what you are able to create. Your indigo dye vat will keep for several

days and dye at least 15 pieces of clothing.

Our Shibori dyed goodies!!! We can’t wait to dye more and even try our hand at recreating this

gorgeous Suno dress.

Resist dyeing Resist dyeing (resist-dyeing) is a term for a number of traditional methods of dyeing textiles with

patterns. Methods are used to "resist" or prevent the dye from reaching all the cloth, thereby creating

a pattern and ground. The most common forms use wax, some type of paste made from starch or

mud, or a mechanical resist that manipulates the cloth such as tying or stitching. Another form of

resist involves using a chemical agent in a specific type of dye that will repel another type of dye

printed over the top.

Ikat Ikat is an ancient technique used to pattern textiles. The defining characteristic of ikat is the dyeing of

patterns before the weaving of the fabric takes place. The patterns are created by means of a resist

dyeing process on either the warp or weft fibres, or on both. We will here look at cotton warp ikat,

the technique most common in the Indonesian archipelago.

Spinning, where it all begins One of the most fundamental skills required to produce a high quality ikat, is spinning. While spinning

wheels have been introduced in some parts of Indonesia, spindle spinning is still practiced in many

parts, especially on the more remote islands, such as here on Alor. In that respect not much has

changed since 1932 when Ernst Vatter wrote in Ata Kiwan: "... in those areas where there still is much

weaving, you rarely see women or older girls without their 'handiwork', the spindle, which they

diligently spin during every pause that their other work allows."

The thread produced by means of a gravity or drop-weight spindle is called benang putar, and textiles

made of it are generally highly appreciated, both by locals and by collectors. The evenness of thread

that an experienced spinner can achieve with a spindle is stunning, yet one can always feel the

difference between commercial, factory made yarns and hand spun yarns by passing it through the

fingers and paying attention to the minute differences in thickness that betray the old handwork.

Bindings that resist liquid are placed before each dye bath The ikat process proper begins with the warp threads being strung up on the loom, close together and

properly tightened. Then the pattern is drawn on to them in outline using charcoal, crayon or sticks

dipped in dye. In most regions the patterns are improvised, with various degrees of freedom and

personal creativity, within a tightly prescribed traditional framework with determines the number and

ordering of bands or stripes, their width, background color, and overall patterning.

Bindings that resist dye penetration are applied to narrower or wider bundles of threads (from as few

as four in very fine ikat) in locations defined by the intended motif. In most parts of Indonesia these

bindings are traditionally made of strips of palm or pandan leaf, raffia, or other plant material, which

in some regions such as Borneo may be waxed with beeswax to improve impregnability, but these

days plastic is also used, allowing greater definition.

Mordanting, if necessary, and dyeing After the bindings required to protect all material that should not be coloured in the first round of

dyeing are in place, the threads are taken off the loom and immersed in the dye bath - or, if the

pigment is of a kind that does not spontaneously penetrate and adhere to the fibre, such as morinda,

they are first soaked in a mordant, then dyed. Indigo, the most common colour in the Indonesian

archipelago, is an ideal pigment to work with, as it adheres to cotton naturally, and is fully colourfast.

After drying, the bindings are cut away, the threads are strung onto the loom again and arranged

carefully so that they match exactly, and new bindings are put in place for all locations that should not

receive colour in the second round of dying. Then the tied threads are taken off the loom again,

immersed in the next dye bath - and so on until the desired multicoloured pattern has been created.

The duration of the soaking of the threads in the dye bath varies from a day to several weeks. In many

regions a particular dye bath may be repeated numerous times to achieve the desired intensity. A

common technique to achieve more colour variation with a limited number of pigments is overdyeing,

once or several times with bindings at different locations.

Arranging died warp threads on the loom When the dyeing process is finished - which, because of ritual prescriptions, scarcity of material, or

the need for multiple immersions in the mordant may take months or even years - the last bindings

are removed and the threads are ready to be woven into cloth. The first step is to arrange the warp

threads on the loom once again, taking great care to align them properly, so that the pattern comes

out clear, well defined. Next to the intensity of the coloration, the clarity of the pattern is the most

important indicator of craftsmanship.

In warp ikat the patterns are clearly visible in the warp threads on the loom even before the plain

colored weft is introduced to produce the fabric. In weft ikat it is the weaving or weft thread that

carries the dyed patterns which only appear as the weaving proceeds. In weft ikat the weaving

proceeds much slower than in warp ikat as the passes of the weft must be carefully adjusted to

maintain the clarity of the patterns. In double ikat both warp and the weft are resist-dyed prior to

stringing on the loom.

Finally: weaving, the end of the process For the weaving of ikat cloth, traditionally, and still commonly, a backstrap loom is used, as below by

this weaver on the island of Alor, though in principle any variant or modern loom might be used. The

textiles in our collection have all been made in the traditional manner.

The backstrap loom has been in widespread use in many parts of South and Southeast Asia since times

immemorial. They are easy to construct from materials that readily available in the natural

environment. The warp threads are attached to two parallel wooden bars or sticks, one of which is

either tied to stakes in the ground, or, in its most primitive form, held behind the feat of the weaver,

and the other is attached to a belt around the weaver's waist.

This setup allows the weaver to relax or tighten the warp threads by a slight movement of the body

either forwards, so as to facilitate the opening of the shed and the insertion of weft threads, or

backwards to straighten out the cloth for inspection and adjustment of the thread alignment.

Backstrap looms come with an inherent limitation of width, namely the span of the weaver's arms. As

a consequence all wider Indonesian ikat textiles consist of two or more panels stitched together along

the selvages.

Leheria Leheria (or leheriya) is a traditional style of tie dye practiced in Rajasthan, India that results in brightly

colored cloth with distinctive patterns. The technique gets its name from the Rajasthani word for wave

because the dyeing technique is often used to produce complex wave patterns.

Leheria dyeing is done on thin cotton or silk cloth, usually in lengths appropriate for turbans or saris.

According to World Textiles: A Visual Guide to Traditional Techniques, the fabric is "rolled diagonally

from one corner to the opposite selvedge, and then tied at the required intervals and dyed". Wave

patterns result from fanlike folds made before dyeing. Traditional leheria employs natural dyes and

multiple washes and uses indigo or alizarin during the final stage of preparation.

Ice (or snow) Dyeing We got the idea for ice dyeing from folks who were sharing their snow dyeing projects with us. With

Ice Dyeing you don’t need to depend on Mother Nature providing any snow, just get some ice, dye

and a bucket and you are off to the races! (But obviously snow works too) This technique is great for

unique dyed garments or for one-of-a-kind dyed fabric for quilting.

Pre-wash your garments or fabric with the Professional Textile Detergent. This will remove any fabric

softeners, oils, dirt, etc that might have gotten on your dyeable blanks or fabrics during manufacturing

or through handling.

Mix up your soda ash, 1 cup per gallon of water, and add in your dyeable items. Let them soak for

about 15 min. Pull them out and squeeze out the excess solution (wear good rubber gloves). You can

save the soda ash for more dyeing later.

Place your cooling rack in a tub (we used this for the shirt and baby romper).

Scrunch up your soda-soaked dyeables randomly and put them on the rack. If you want to, you can

pleat them or tie them up more like tie-dye. It’s up to you.

For the fabric we roughly pleated the Kona Cotton and scrunched some remnants of Silk/Rayon Velvet

and Cotton Velour to fill the bottom of the tub.

Next, cover everything in ice. We used one 7.5 lb bag of regular cubed ice on the fabric and about half

a bag on the shirt and romper.

Time to put the dust mask on! We are going to be using the dye powder and we want to be safe about

not inhaling any fine particles of dye.

Grab your first color and start sprinkling the dye powder on the ice. Be as random or as specific as you

want with how you spread the dye. Remember, as the ice melts colors will mix and blend as they hit

the shirt. So if you put yellow and blue together, you will get greens. On the other hand, part of the

fun is that “mix” colors will split up a bit into their component colors, giving you neat effects. You can

use this to your advantage when choosing your colors.

Once everything is sprinkled to your liking, cover the tubs with some plastic and let the melting

progress. Putting the tubs in a warm place can speed things up. Let it all sit this way for 24 hours.

The fabric in the tub may look like a big pool of black or brown colors. Don’t worry, it isn’t going to

end up all muddy, we promise. The items that were elevated so the melt water could drain away are

a little less scary looking.

Take your tubs over to the sink and start rinsing your items in COLD running water. Rinse until the

water is running mostly clear.

Finally, toss everything in the wash with HOT water and Professional Textile Detergent. Dry and wear

your ice dyed garment! Or cut and sew your ice dyed fabric!

Space Dyeing Indie dyed variegated yarns and rovings are all the rage now and they are easier to create at home

than you might think. Create your own bright or subtle variegated yarns and rovings with this easy

technique. You will soon have unique one-of-a-kind colorways for all your projects.

Using the cotton twine, tie your skein loosely in a few more places; you want at least 4 ties around the

skein to help keep it organized and untangled.

Fill the bucket or dish tub with warm tap water, a drop or two of Synthrapol and Citric Acid/Vinegar.

Use 1 TBS of Citric Acid per quart of water or if you are using vinegar use 50/50 water to vinegar in the

soak as vinegar is more dilute. (Ex: 1 cup water to 1 cup Vinegar) Lower the skein into the water by

one of the ties and gently push it down under the water with the large spoon. Let it soak at least 1

hour, but overnight is ideal, especially for finer fibers like alpaca and silk. You want the fibers to be

completely soaked.

Use the salad spinner or the dryer to spin out excess soak water until the yarn is just damp to the

touch. Cover your work space with plastic wrap; be sure to overlap a couple pieces as you are going

to wrap the yarn in it and you don’t want dye to leak out. Lay out the yarn on the plastic wrap. Lay

your yarn out flat over the plastic wrap. Mix your dyes with hot tap water, making sure they are fully

dissolved, and pour them into the squeeze bottles. Snip the tip of the bottles so the dye flows out

easily but not too fast.

The amount of dye depends on how dark you want your colors. The yarn we used comes in an

approximately 150 gram skein. Normally we would want to use 1.5% weight of goods for a solid color,

about 2.25 grams of dye. Since we are using four colors we want to divide that to about a ½ gram of

dye per color. If you are using black, then use 1 gram of black. This roughly works out to about ¾ tsp

per color for a medium shade, in most colors, and 1.5 tsp for black. Use more or less dye for different

shades. Start applying the dye. Using the squeeze bottles, apply the first color to different areas of the

yarn. Only use about half the dye and then go on to the next color. Once you have coated one side of

the skein, carefully flip the skein over and apply the same colors in the same pattern on the back of

the skein. Check to make sure the dye is getting into the center of the skein. You can gently push the

yarn around a bit to help the dye penetrate.

Fold the plastic wrap over your yarn/roving length-wise then fold in the ends. If you can, fold the skein

in a couple times to make a packet that will fit in your pot for steaming. In your steaming pot put a

couple inches of water and the steamer basket. Make sure the steamer is going to hold the yarn/roving

out of the water. Heat it up to a simmer on high and then turn the heat down. You don’t want it to

boil away too quickly but you need plenty of steam. Place the yarn onto the steaming basket in the

steamer and put on the lid. Let it steam for about 45-60 min. You can steam multiple skeins at once,

as many as your steamer will hold without stacking them.

Let the yarn cool a bit before you unwrap it and let it cool further before rinsing. You don’t want to

shock the yarn by rinsing it too soon as it can result in felting. Once it is mostly cool, soak it in cool

water with a bit of Synthrapol. Do a couple rinse soaks with just plain water. In the last soak you can

use some Eucalan Wool Wash to smooth the yarn and make it soft again.Spin the water out one last

time to help the yarn dry faster. Once it is dry you can wind it into a ball and start knitting, crocheting

or weaving the project of your dreams. Dye up some more skeins and arrange them in a nice basket

in your craft room for inspiration!

Crystal wash dyeing This is a form of "low immersion" dyeing that results in a sharp distinct crystalline looking pattern.

Unless you have teeny buckets, this works best with an adult tee or larger garment or piece of fabric.

Basically, whatever you are dyeing, you need a container small enough that it will be a tight fit when

scrunched in. The pattern will usually be more distinct than "low immersion" or "baggie dyeing",

where the fabric is looser. There are great instructions for traditional low immersion dyeing that many

quilters prefer in the book Color by Accident by Ann Johnston. It is excellent! She goes into gradation

so that you can dye many squares of fabric from light to dark, or from one color to the next. Another

great book on low Immersion dyeing is Tray Dyeing by Leslie Morgan and Claire Benn. This book also

comes with a DVD showing the techniques.

Step 1: Soak 100% cotton shirt (or fabric or whatever) in Soda Soak solution, follow Step 2 of our Tie

dye directions - wring out excess.

Step 2: Lay the garment flat on a protected surface and use your fingers (in gloves) to sort of bunch it

together into a flat scrunched round biscuit shape.

Step 3: Cram the garment into the bottom of a very small bucket or other container. It needs to be

very tight. If this is not possible, put rubber bands all around it so it is like a big pie.

Step 4: Squirt on 1 or more colors of Procion Fiber Reactive dye mixed up according to the Tie dye

directions.

Step 5: If you want white in the areas where the dye doesn't penetrate, for strong contrast, just let it

sit 12-24 hours, then wash out as recommended in our Tie dye directions.

Step 6: If you want lighter color (instead of white) in the areas where the dye doesn't penetrate, push

on the garment a little with a stick or gloved hands to push some of the dye in deeper.

Cool Variations

Step 1: Instead of soaking the shirt in Soda Ash solution, soak it thoroughly just in water, then scrunch

it up on a protected flat surface and rubber band it as above. Put it in a bucket or plastic tub.

Step 2: Dissolve a 1/2 cup or so of soda ash in some warm water - however much it takes to dissolve

it.

Step 3: Carefully sprinkle pure dye powder (cheap plastic salt shakers work very well!) in several

different colors on one side of the shirt- aim for "non-uniform coverage". Wear a dust mask!!! For a

"rock effect" use several different shades of browns and greys, or for a "water effect" use several

shades of blues and aquamarines. You get the picture. Use colors that mix well together, and don't

just make "mud".

Step 4: After 2 or 3 colors of powder, carefully pour on just enough "soda ash water" to get the dye

wet that you just put on, then sprinkle on a couple more colors, then more soda ash water. You can

use up to 5-7 colors total.

Step 5: Carefully drain the excess soda water and dye that has accumulated in the bottom of the

bucket, flip the garment and repeat Steps 3-4. Don't be alarmed if the garment just looks like a muddy

mess! Drain the excess at the bottom of the bucket again. Push on the garment with a stick or gloved

hands to push some of the dye in deeper.

Step 6: Leave it sit 12-24 hours, then wash out as recommended in our Tie dye directions.

Step 7: If the garment ends up with too much white on it, you can then re-scrunch the garment, rubber

band it, and dye it in a light colored dye bath according to our Tub dyeing directions. Use a color that

goes with all of the others you have used.

Direct Dyeing When a dye is applied directly to the fabric without the aid of an affixing agent, it is called direct

dyeing. In this method the dyestuff is either fermented (for natural dye) or chemically reduced (for

synthetic vat and sulfur dyes) before being applied. The direct dyes, which are largely used for dyeing

cotton, are water soluble and can be applied directly to the fiber from an aqueous solution. Most

other classes of synthetic dye, other than vat and sulfur dyes, are also applied in this way.

Stock Dyeing Stock dyeing refers to the dyeing of the fibers, or stock, before it is spun in to yarn. It is done by putting

loose, unspun fibres in to large vats containing the dye bath, which is then heated to the appropriate

temperature required for the dye application and dyeing process. Stock dyeing is usually suitable for

woolen materials when heather like color effects are desired. Wool fibre dyed black, for example,

might be blended and spun with un-dyed (white) wool fibre to produce soft heather like shade of grey

yarn. Tweed fabrics with heather like color effects such as Harris Tweed are examples of stock dyed

material. Other examples include heather like colours in covert and woolen cheviot.

Top Dyeing Top dyeing is also the dyeing of the fibre before it is spun in to yarn and serves the same purpose as

stock dyeing – that is, to produce soft, heather like color effects. The term top refers to the fibres of

wool from which the short fibres have been removed. Top is thus selecting long fibres that are used

to spin worsted yarn. The top in the form of sliver is dyed and then blended with other colors of dyed

top to produce desired heather shades.

Yarn Dyeing Yarn dyeing is the dyeing of the yarns before they have been woven or knitted into fabrics. Yarn dyeing

is used to create interesting checks, stripes and plaids with different-colored yarns in the weaving

process. In yarn dyeing, dyestuff penetrates the fibers in the core of the yarn. There are many forms

of yarn dyeing- Skein (Hank) Dyeing, Package Dyeing, Warp-beam Dyeing, and Space Dyeing.

A. Skein (Hank) Dyeing Skein dyeing consists of immersing large, loosely wound hanks (skeins) of yarn into dye vats that are

especially designed for this purpose. Soft, lofty yarns, such as hand knitted yarns are usually skein

dyed. Skein dyeing is the most costly yarn-dye method.

B. Package Dyeing In package dyeing the yarn is wound on a small perforated spool or tube called a package. Many spools

fit into the dyeing machine in which the flow of the dye bath alternates from the center to the outside,

and then from the outside to the center of the package. Package dyed yarns do not retain the softness

and loftiness that skein-dyed yarns do. They are however satisfactory and very widely used for most

types of yarns that are found in knitted and woven fabrics.

C. Warp Beam Dyeing Beam dyeing is the much larger version of package dyeing. An entire warp beam is wound on to a

perforated cylinder, which is then placed in the beam dyeing machine, where the flow of the dye bath

alternate as in the package dyeing. Beam dyeing is more economical than skein or package dyeing, but

it is only used in the manufacture of woven fabrics where an entire warp beam is dyed. Knitted fabrics,

which are mostly produced from the cones of the yarn, are not adaptable to beam dyeing.

Piece Dyeing The dyeing of cloth after it is being woven or knitted is known as piece dyeing. It is the most common

method of dyeing used. The various methods used for this type of dyeing include jet dyeing. Jig dyeing,

pad dyeing and beam dyeing.

Garment Dyeing Garment dyeing is the dyeing of the completed garments. The types of apparel that can be dyed are

mostly non-tailored and simpler forms, such as sweaters, sweatshirts, T-shirts, hosiery, and

pantyhose. The effect on sizing, thread, zippers, trims and snaps must be considered. Tailored items,

such as suits or dresses, cannot be dyed as garments because the difference in shrinkage of the various

components and linings disort and misshape the article.

Garment dyeing is done by placing a suitable number of garments (usually about 24 sweaters or the

equivalent, depending on the weight) into large nylon net bag. The garments are loosely packed. From

10 to 50 of the bags are placed in large tubs containing the dye bath and kept agitated by a motor –

driven paddle in the dye tub. The machine is appropriately called a paddle dryer.

Stovetop Fabric Dyeing Tintex is a hot water dye, if possible, keep water temperatures at 140°F to get the best result. Ensure

that fabric is clean and preferably wet before dyeing. Test techniques to get familiar with the process

before dyeing all of your real fabric. Tintex is not for 100% polyester or 100% acrylic fabric. Fabric

blends can be dyed but, 100% polyester or 100% acrylic fabrics may not respond to a hot water dye -

- proceed at your own risk.

Wear rubber gloves to prevent dye or hot water from coming into contact with your skin

Bucket/Sink/Bathtub Dyeing with a bucket, sink, or bathtub helps you get great results for your delicate or more unusual

items. Do not use fabric dye in porcelain or fiberglass bathtubs (due to the strong possibility of

staining).

Tintex is a hot water dye, if possible, keep water temperatures at 140°F to get the best result. Test

techniques to get familiar with the process before dyeing all of your real fabric. Tintex is not for 100%

polyester or 100% acrylic fabric. Fabric blends can be dyed but, 100% polyester or 100% acrylic fabrics

may not respond to a hot water dye -- proceed at your own risk.

Wet the item fully and squeeze out excess water

Fill bucket/sink/bathtub with a sufficient amount of the hottest water available so to ensure

that the item will be completely submerged but do not place the item in the water yet

Determine the amount of Tintex dye you require (based on the type and weight of the material

you are dyeing) and add the dye to two cups of hot water, stirring until completely dissolved

Create your dye bath by adding the dye mixture to the hot water in your bucket/sink/bathtub

and stir/agitate until it is evenly dispersed throughout the water

Slowly add your item to the dye bath and use a stirring device (or your hands in rubber gloves

– careful, the dye bath will be hot) to move the item through the dye bath for approximately

30 minutes

Remove the item from the dye bath and gently squeeze the excess dye solution out of the

item back into the dye bath (do not wring)

Run cold water over the item to remove excess dye from the item, and continue doing this

until water runs cleanly from the item

Allow the item to air-dry, and iron on a low setting when slightly damp

Clean the workstation using soap and/or bleach (if applicable) with warm water as soon as

possible after dyeing

Microwave Fabric Dyeing We found another way to use our microwave - Fabric dyeing. This method is a fast way to get great

dyeing results.

Prepare a dye mixture by adding the required amount of Tintex dye to two cups of the hottest

water available and mix thoroughly microwave until it is completely dissolved

Pour the dye mixture into a microwave-safe glass bowl and combine it with as much hot water

as needed in order to completely cover the item you wish to dye

Mix the water and dye mixture thoroughly to make your dye bath

Place your wet item in the dye bath and ensure that it is completely immersed

Cover the top of your bowl completely using plastic wrap

Place paper towels or newspaper on the rotating tray in the microwave to prevent staining

Place the bowl in the microwave and turn it on high for approximately two minutes

The bowl will be extremely hot - with extreme caution, use rubber gloves to remove the bowl

from the microwave and set it on paper towels on your kitchen counter close to your kitchen

sink, or in the sink directly

Allow the dye bath to cool for approximately five minutes, then remove the item from the dye

bath and place it in the kitchen sink using rubber gloves

Run cold water throughout the item and gently squeeze it until you notice the excess water

flowing from the item runs clear

Gently squeeze excess water from the item but do not wring

Allow the item to air-dry and iron on a low setting when slightly damp

Ombre Ombré is a by-hand dyeing method of creating a gradual shaded look. For example, an Ombré blanket

may be navy on the bottom and gradually fade to a lighter blue toward the top of the blanket.

Set up your work station: place a large plastic sheet on the ground and place a large bin in the

center

Wear rubber gloves to protect skin

Carefully fill the bin with two gallons of hottest water

Prepare your dye solution by adding dye to 3-4 cups of very hottest water and mixing well

until completely dissolved

Add the dye solution to the bin of hot water and agitate well until mixed evenly

Place the bottom third of the clean, dampened item into the dye bath, leaving it immersed

and moving it around slightly for approximately 10 minutes

Add another 1/3 of your item into the dye bath leaving it immersed and moving it around

slightly for approximately 5 minutes

Quickly dip the rest of the item into the dye bath

Gently squeeze the extra dye solution out of your item but do not wring

Run cold water down from the lightest shade to the darkest to remove extra dye until water

runs clear

Allow your item to air-dry and iron on a low setting when slightly damp

Clean the work station using bleach (when safe) and warm water as soon as possible
