What is Yarn?
In textile sector, yarn is a long continuous length of interlocked fibers. Yarn is suitable for using in the production of textiles, knitting, weaving, rope making, crocheting and weaving etc. There are two sets of yarn (such as warp yarn and weft yarn) used in woven fabric manufacturing technology and one set of yarn is used knit fabric manufacturing technology.

What is Warp Yarn?
Warp yarn is that which is used in the longitudinal direction of woven fabric. It is used for preparing weavers beam.

What is Weft Yarn?
The yarn which is used for cross interlacement through the warp beam is known as weft yarn. It should be noted here that, warp yarn count is finer than weft yarn count.

Quality Requirement for Warp and Weft Yarn in Weaving:
Yarn must have some important qualities which will ensure the required quality of fabric. All those properties have presented in the below:
  1. Yarn cross section must be uniform.
  2. Yarn must be sufficiently and uniformly strong.
  3. Yarn must be uniform in cross section.
  4. Yarn must have less hairiness as much as possible.
  5. Proper and standard type and size of knots.
  6. Yarn must be clean and free from all kinds of dust.
  7. Yarn should be free from count variation.
  8. Knots in yarn must be in less number.
  9. Sizing should be done accurately in warp yarn otherwise it creates problem during passing through heald eye.
  10. In the weavers beam, arrangement of warp yarn must be parallel.
  11. Yarn should be free from loose fibre, neps and slubs as much as possible.
  12. Tension of warp yarn in warp beam must be uniform.
  13. Knots must be standard size and type so that they can pass through the heald eye, dropper and read easily.
  14. All warp ran should of same size in length.
