of the fabric and the weft threads are placed along the width of the 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 on a package.

5.To
make good quality fabric.
6.To
reduce labour 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 uniform, clean and
free from knots as much as possible.
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 a weavers beam at even and equal tension.
6. All warp yarns should be of the same size
in length.
