TEXTILE
•Textile is a Latin word which refers to Woven Fabrics.
•The term now has a broader meaning and covers materials which are produced by other means , including:
–the interlacing of yarns, such as knitting, lace making and netting;
–other needlework techniques worked through a woven base, such as embroidery and canvas work.
–Some examples of textiles •costume, uniforms;millinery;tapestries;ecclesiastical textiles;carpets and rugs;dolls & soft toys, parasols and fans;patchwork and applique;flags and banners;quilts;needlework;curtains, upholstery;ethnographic textiles;samplers;non-woven materials such as felt,etc.

Yarn

YARN
• Yarn is defined as a linear assemblage of the fibers twisted together.
• The process of making the yarn from a textile fiber is called Spinning

YARN MANUFACTURING PROCESS (Cotton)
• BALE OPENER• MIXING• BLOW-ROOM • CARDING• DRAWING• COMBING • SIMPLEX (ROVING)• SPINNING (RING FRAME)

Bale opener

BALE OPENING
• BALE OPENING or BREAKING:
• The cotton tufts are opened in this process.
• As the cotton arrives in an extremely compressed condition the first operation is to loosen the matted fibers
• The cotton fiber is loosen by means of rotating spiked rollers of the bale opener.

Mixing
![Page 10: Textile Basic Spinning](https://reader036.vdocuments.site/reader036/viewer/2022081502/5695d0651a28ab9b029249ee/html5/thumbnails/10.jpg)
Mixing
• This is a process of mixing the same/different category of fibers to get desired properties and cost effectiveness.
• Mixing is done after the study of the essential properties of fiber like staple length,Tensile strength, fineness, uniformity etc.

Blow room
![Page 12: Textile Basic Spinning](https://reader036.vdocuments.site/reader036/viewer/2022081502/5695d0651a28ab9b029249ee/html5/thumbnails/12.jpg)
BLOW ROOM
• In this process the cleaning and opening of the cotton is done by beaters and openers.
• The foreign materials like dust particles, seeds of cotton and other impurities are partially removed in this process.
• The cotton tufts are opened and cleaned in this process and the cotton lap is made out.

Carding

CARDING
• Carding is the heart of spinning in this process the minute impurities like small seed particles,immature fibers etc. are removed.
• The straightening and aligning of fibers are done in this process.
• In carding the Blow room lap is attenuated to the card sliver.

Draw Frame
![Page 16: Textile Basic Spinning](https://reader036.vdocuments.site/reader036/viewer/2022081502/5695d0651a28ab9b029249ee/html5/thumbnails/16.jpg)
Draw Frame
• Through drafting fibbers get paralleled
• Up to Eight Carded Slivers are fed into the Draw-Frame and they are stretched/Straightened and made into a single sliver.
• Also fiber blending can be done at this stage.

Simplex
![Page 18: Textile Basic Spinning](https://reader036.vdocuments.site/reader036/viewer/2022081502/5695d0651a28ab9b029249ee/html5/thumbnails/18.jpg)
Simplex (Roving Frame)
• Further drafting is done here to get the fibers more aligned/paralleled.
• The Sliver from Draw-Frame is thicker and will be difficult to be fed into the Ring-frame as is, hence here the Slivers are stretched and were made thinner by Drafting and mild twisting (so as to strengthen the Roving).
• The End-Product from the Simplex is called as Roving.

Ring Frame
![Page 20: Textile Basic Spinning](https://reader036.vdocuments.site/reader036/viewer/2022081502/5695d0651a28ab9b029249ee/html5/thumbnails/20.jpg)
Ring Frame (Spinning)
• The roving is fed into the Ring-frame and is made into yarn by further Drafting & Twisting.
• Basic Functions of Ring Frame • to draft the roving until the required fineness is achieved
• to impart strength to the fiber, by inserting twist.
• Depending upon the yarn count required , the drafting and twisting can be adjusted.
