WEAVING OBJECTS OF YARN PREPARATION

TEXTILE

A Textile was originally a woven material, but now the term textile and its plural textiles are applied to fibers, filaments, yarn and most product that these are a principle raw material, the product includes threads, cords, ropes, braids, woven, knitted, non-woven materials, nets, household textile, Geo-textile, medical textiles etc.

WEAVING

Weaving is the action of manufacturing fabric by the interlacement of warp and weft thread. The warp threads are placed along the length of the material and therefore the weft threads are placed along the width of the material.

Geo-Textile:   Embankment

Medical Textile:  Non-alginate fabric

Three types of yarn package are mentioned bellow

Conical                  Flange bobbin          Cheese

1. Woven fabric (Shirt)

2. Knitted fabric (T-shirt)

3. Non-woven fabric (Tea pack)

4. Special fabric (Fire proof fabric, waterproof fabric)

OBJECTS OF YARN PREPARATION

1. To remove objectionable yarn faults (there are 23 types of yarn faults)

2. To transfer the yarn from spinner package to a convenient form of a package which will facilitate weaving.

3. To have the desired length of a package.

4. To clean the yarn for higher appearance and performance.

5. To make good quality fabric.

6. To reduce labor cost.

7. To remove weak places

8. To make a compact, uniform  and fault-free package

  

QUALITY OF GOOD WARP

1. The yarn must be clean and free from knots as much as possible and uniformly, .

2. The yarn must be sufficiently strong to withstand the stress and friction without any end breakage.

3. Knots should be of a standard size and type. So that they can pass through the Heald eye, dropper, reed easily.

4. The warp must be uniformly sized and size coating should be thick enough to protect the yarn from various frictional forces.

5. The ends of warp must be parallel and each must be wound onto onto a weaver's beam at an even and equal tension.

6  All Warp yarns should be of the same size in length.
