Knitwear Technology (Fully fashion)

Page 1 of 30

Knitwear Technology (Fully fashion)Knitting: Knitting is a inter locking / inter looping / inter matching of loops which form a structure is called Knitting.

Weaving: weaving is a interlacement of two sets of yarn at right angles which form a structure is called weaving.

Loop: banding form of yarn is called loop.

Apparel

Light heavy

Fine gauge sweater

Classification of knitted structure:

Knitted structure

Weft knitted structure Warp knitted structure

Circular knitting Flat bed knitting Tricot Raschel Small Large dia m/c dia m/c Hand driven Power driven - Drive manually - Driven in power End products:End product: - limited design - unlimited/fancy Socks T-shirt can produce design can produce - Multi non apparel seam polo shirt - low volume - High volume can produce. production production - Mosquito net.-Fabric for clothing - Integrated gmts - Integrated garments - Mesh fabric.- Single Jersey not possible possible - Power net.- Rib knitted structure - Fish net- Double jersey End products: sweater, fully fashioned - Laces etc.- Lacoste / pique knitwear, cardigan, poll over etc Describe the various structures:

Warp knitted structure: lengthwise (warp wise) direction of loops is called warp knitted structure.

Mesh fabric: supporting fabric, look like a mosquito net use in short garments.Power net: use in Hajack lamp.

Weft knitted structure: widthwise (weft wise) direction of loops is called weft knitted structure.Wales: vertical columns of loop are called Wales

Course: horizontal raw of loop is called course.

Types of knitting m/c:.

Circular knitting m/c: Needles are arranged in circular way thats why it is called circular knitting m/c. It has two needle beds. One is cylinder (vertical needles)

Another is dial (horizontal needles) Dia: maximum circle distance in a circle is called dia. Two types of dia small dia (for socks)

large dia (cutting fabric lacoste/pique)

Gauge: It means thickness. no. of gauge

Fine gauge : T-shirt (24g, 40g) Course gauge: sweater (3g, 5g)

Higher the gauge finer the knit, lower the gauge courser the knit.

Flat bed Knitting m/c: Needles are arranged in flat way thats why it is called flat bed knitting m/c. It has two needle beds.

-Technical front (T.F)

- Technical back ( T.B)

It is also called Jacquard m/c.

Integrated garments: without any stitch or linking in garments. without any join, seamless garments.Shem seiki: Shem seiki is first producer of whole garments in Japan. Company name is also known as brand.

-Ladies shirt is known as ladies blows.

- Heavy knitwear means sweater.

Why it is called fully fashion?

Fully fashion: Fully fashion is a method / technique of shaping a knitted structure by increasing or decreasing the number of needles or wales.

In the fully fashion there is no fabric formats. Just it is made by increasing or decreasing the shape of end product, increasing or decreasing of needles.

Advantages of fully fashion:

we can produce zero(less) wastage garments.

Less manpower.

we can produce quality garments/sealed garments.Disadvantage:

Textile fiber: anything that can be garments/originated from fiber.

In narrow sense: Textile means fiber to fabric production. ie fiber yarn fabric

In greater sense: fiber clothing

Fibers are chemical/natural structure that can be spun into yarn.Basic requirements for fibers:

Based on sourcing:

Textile fiber

Natural Chemical made Animal (wool)

Plant/vegetable (cotton) Acrylic

Fiber: any types of substance but the length and thickness ratio is very high.

Thickness and length ratio 1:800, 1:1000 etc

Major properties of fiber:

1. Mechanical properties:

Abrasion resistance

Flexibility

Stiffness.

2. Absorption properties: this is a measure of quality of water vapors, liquid water etc.

ie water absorption. Water/oil release. 3. Thermal properties: The behavior of textile in the presence of heat or when exposed to a flame.

- Heat resistance capacity. - Soften and melting.

Fiber identification test:1. Burning test: Wool Acrylic Cotton Flammability Not flammable highly flammable flammableBurning smell hair burning smell petrol burning smell paper burning smell

2. Chemical test: (-) alkalies (+) alkalies (+) alkalies (+) acids (+) acids (-) acids poor resistance in alkalis

good resistance in acids

3. Microscopic test:

Based on length:

Fiber

Staple Filament

Acrylic Short Long (2000 mtr) Cotton Wool

(1.27 6.34 cm) (3.8 cm)Textile yarn:

Yarn: twisted form of fibers is called yarn. ASTM: American society of textile materials.

ASTM definition of yarn: A generic term for a continuous strength of textile fibre is called yarn.

Classification of textile yarn:

Textile yarn

Span Filament

Simple complex/ fancy/ vovelty

Mono Multi

Single Plied

Cords cables Flat TwistedVisual properties: -Mono

- Multi

- Staple

- Two ply yarn

- Multi ply yarn

- Cord

- Cable

Span yarn: Twisting together of staple fiber.Single yarn: consists of just one stand of fibre.

Plied yarn: are art formed by twisting together two or more single.

Cords: are made by plying / twisting together by plied yarn.

Cables: are produced by plying cords.

Complex/ fancy: This has special effect on.

Slub yarn: contains partially bulky / fluffy.

Loop yarn: this yarn requires a base yarn (core yarn) around which fancy or effect yarn is warped.

Wool yarn: Sheep (fleece of sheep)

Lower part upper partVarious levels: Pure wool: 100% wool

Virgin wool: raw wool

Blended wool: 70% wool & 30% acrylic

Basic properties of wool:

It is heavy due to bulky fiber

Dull in appearance

Strength is very poor

Poor resistance in sunlight and heat.

Cool and low steam use

Insects from poor resistance

React in alkalis

Shrinkage.

End use: Fully fashion, shut.

Acrylic: Acrylic is known as acrylonitrile which we get from acetylene of ethylene.

Acrylic is also known as cheaper substitute of wool.

Basic properties of Acrylic:

Light shining

Good strength

Comparatively low worm

Not react in sunlight.

First look bright but second it creates boblin.

Especially in heavy weight.

Cotton:

10 g, 12 g ------ Buyer prefer

Cotton yarn -------summer or spring

-------Fashion & Requirements

Basic properties of cotton:

Smooth and fine

Cool feeling

Strength medium to high

Insect dont like.

Disadvantages:

Low resistance

End use: Knit, woven, fully fashion, inner and outer garments.

Yarn use in fully fashion:

Production Merchandising

1. Yarn quantity

a. Material quantity

b. Type of gage

Material: - 1. Strong yarn /Good strength

2. Less strength. (Chenille)

Gage: Normal gage 3g, 5g, 7g (16,1bs + 4%)

Fine gage --- 10g, 12g ---- (16,1b + (4+1) %) (Shadel +1%)

1. Why we weight the yarn?

If not weight the yarn then worker miss use the yarn. In distribution room blog/protection because any worker could not entered the distribution room.

Fully fashion m/c

- Less manpower

- Quantity

-Design low

Knitting process is depend on design chart

Heart of the sweater production operator could not idea about actual design chart .So they could not say how to design it. They learn if with experience not scientific way.

7 gage: - 7 needles exist in per inch.

Fabric fault in fully fashion: -

1. Hole

2. Laddering3. Ply mistake --- yarn broken.

Why we women worker in mending section?

Here is poor salary and women are expert in mending and they have biological support.

Tremble drying m/c.

Boiler ----- Steam iron.

Different types of stitches / Design used in fully fashion Basic category: -

1. Jersey stitch Fancy category

2. Rib stitch -- shaker / Half cardigan stitch.

3. Double jersey --- Full cardigan stitch

Cables:- --Milano stitch

1. Normal -- Tuck stitch

2. Fancy --printal stitch

3. Butterfly -- Zigzag stitch

-- Drop knit stitch .

Diamond:-

1. Normal

2. Fancy

Stitch An intermeshed loop.

Describes different types of stitches / Design ------

Jersey / Single jersey/single knit / plain knit / basic knit etc.

This is very basic knitting construction .Its a single beded structure .The needle diagram of jersey is ------------

The stitch diagram is ------

It can produce both in flat bed 4 circular bed m/c-

Properties of Jersey stitch:-

Appearance: - In single Jersey both side are different in appearance.

Out look:-

T/M: V Shape stitch /jersey stitch.

T/B: Semi circle stitch /Are stitch.

Edge curling : it curls T/B to t/B

T/B to T/B in width wise

Length wise wilts wise

Strength: - Tightness and looseness activity.

Yarn tension T/F to T/B G curl -Unbalanced fabric because back side no needle.

Carling so worker take time to linking and producing extra time.

How to reduce the curly:-

1. After knitting and before sewing /linking by using parching. (Light knit circular knit swach)

2. Use folder /attachment

3. Use standard m/c

Dimensional stability: - Because of single jersey dimensional stability in poor.

S.J garments do not washable.

How to reduce the dimensional stability?

1. To increase loop density

2. Apply resin finish chemical resin use properties shaf t - Soft ness

- Estability / elasticity.

Elasticity:-Length and width wise elasticity is same because course and wales wise loop length almost same.

Unraveled: we can unroalled this structure in both side.

How ladering defect create

1. Needle head broken.

2. Loose tension.

3. Knot in the yarn.

Rib knitted structure:- The word rib derives from animal rib. This is a double beded structure. The needles heads are not facing directly each other. There are various types of rib knitted structure.

But very common structure is 1x1 & 2x2 rib; above3x3, 4x4 etc are known as fancy rib. But 6x6 rib is known as specially Derby rib.

The needle diagram of 1x1 ribs and stitches diagram of 1x1

The needle bed of 2x2 and stitch is can produce both flat bed and circular bed knitting m/c.

Appearance: - Same in appearance.

-semi circle loop can be observed between in v shape. Edge curling: Rib structure does not curl at the edge. Its balanced structure.

Dimensional stability:-Dimensional stability is good.

Elasticity:-width wise direction is high than that of length wise.

Why width wise elasticity high?

-Semi circle width is high, so width wise elasticity high. Unraveled from close it only.

Density: - Density is high in temperature in single jersey.

End use : - waist band, collar, cuff or total sweater. we can use by rib fabric.

High rib under garments, because elasticity and comfort ability.

Similarities between the single jersey and rib Structure.

1. we can produce the Single Jersey and Rib fabric in similar flat bed and circular bed knitting m/c.

2. Both types fabrics are knitted structure.

3. Both fabrics are mend able.

4. created by loop formation.

Double jersey / Interlock/ Double faced fabric:

If the plain stitches are one bedded, the other fabric structure is known as double jersey / interlock.Its double bedded fabric, can produce both in flat bed & circular bed knitting m/c. The needle diagram of double jersey is ------and the stitch diagram is ------

It is called tight knitted. Theoretically needle heads are kept face to face but practically needle heads are not face to face. It stay little bit in angle.

Properties and appearance.

1. Both side similar.

2. Curl: Double jersey does not curl because it very tight knitted fabric.

3. Dimensional stability good..

4. Unraveled : Same as rib.

5. Elasticity : Poor

6. Defecting: It laddering occurs. We cant mending like rib & jersey.7. Density : Density high because both side needles are active.

Thickness & elasticity consider while identifying double jersey.

End use: Sweater

Gents & ladies wear

Light knit. Sports wear ( suet absorbency high, dimensional stability high )

Ladies shirt.Similarities between D/j and rib :

Basic knit Both can made in flat bed circular bed m/c. Both fabrics both side appearance same Does not use. Dimensional stability good. Unraveled: Both are same.Difference between D/j & Rib 1. Needle diagram

Notation for knitted structure :The symbol which represent different types of loops are called notations. There are two types of symbols. We use to identify different structure like

Indicate technical face (v) loop Indicate technical back loop.So for single jersey -Impotency :

1. Language variation avoided

2. Different name confliction avoidance.

3. Loop drawing is difficult and time consuming to avoid this problem

Process break down (operation break down) of a fully fashion knitwear:Step by skip (body panel)

Select & setting needles for bottom rib .

By needle selection for sleeve panel:

If the body is in search

For jersey setting by loop transfer comb

Knit up to am hole start point

Pre pare arm hole by decreasing or

Decreasing or increasing both processes.

Also prepare back drip and reached up to

Neckline shoulder line.

Identification of different types of fancy stitches/design

1. Shaker/Half cardigan stitch:

a. Normal construction 1X1 rib, double bedded structure. T/F & T/B

b. T/F-looks bulky/Fluffy V loop

c. T/B-looks tight V loop as chain stitch

2. Full cardigan stitch :

Normal construction 1X1 double bedded both side same. Both side raised V shape like, but zigzag.3. Milano stitch:Normal construction double jersey ie, full needles from both side needle bed. T/F & T/B not same.

T/F looks joint V stitch like after stitch

T/B looks chain or tight V shape.

4. Drop knit:

Could be any construction, like single jersey, rib, double jersey setting . Like 5X1, 4X2, odd setting etc.

5. Zigzag :

Could be in any construction like single jersey, Double jersey. Vertical in hand driven.

Tuck stitch :

Normal construction 1X1. could be single tuck or double tuck appearance. Looks like single side honey comb both side honey comb.

Cables: There are three types of cables

Normal

Fancy

Butterfly

Cables normally jersey.

Diamond: Normal

Fancy

Double

half diamond

Needle

Pointed stitch :

Could be any construction.

Knit wear ( Fully fashion ) stitch analysis Style: Individual properties Something own.

Fashion: overall Related common geography , culture, age, sex, values, it could be varied.

What are the objective of style analysis 1. Evaluate merchandise classification.

2. Plan fashioning ( design chart/ pattern chart)

3. Calculating / setting comparative costing and pricing.

If a merchandiser fiercest the style/ fashion then he/she kept to idea about the western culture on western recent style/fashion. Why we select the different fashion?

Design Chart:It is a heart of the fully fashion and very expensive factor.

Sweater style ( based on some ) factors:

Like

1. Body style/shape

2. Shoulder style ( Arm hole style)

3. Collar style/ neck style.

Fashioning (Design chart/pattern chart) calculation for fully fashion knitwear

What is design: Design is a creative indexer to solve a problem.What is design chart: Design chart for a garment is a visual written instruction

Design chart produce in two methods:

a) Out line method

b) Graphical method

What is the basic requirement to calculation design chart?a) Size specification (Measurement)

b) Gage type

c) Weight of the garments

Pattern: Shape create by increasing or decreasing size that is called pattern.

Art: Art is the blue print of the design.

Design: Actual shape of the thing.

Swatch: Small part of the fabric. Tension: Tight are looseness of the yarn is called tension.Buyers required weight accordingly tension setup. But in seven gage m/c 8 or 6 needle coming for tension. So tension selection in important because it is related to quality.

Swatch identification:

Excremental swatch wash dry pressing keep 24 hours rest 24 hours actual mesurment yarn effect colour fastness, responsibility etc. Idea counter swatch compare.

Calculating yarn consumption for fully fashion knitwear

What is consumption?

In the garments trade, consumption means quantity of raw materials with a view to determine the price of a garment. In order to calculate the above quantity how much fabric, raw materials, sewing thread, accessories are required to produce a garments up to the exporting is called consumption.What is the unit of consumption: lb/oz

What are the requirements of calculation consumption?

-Material quantity

-Type of gage

-Business type of factory / buying house

-Weight of garments

Two types of yarn

a) Good Yarn

b) Poor Yarn.What types of buying house exist?There are three types:A) Direct order

B) Liago office

C) Corporate office: factory exist

Types of gage
