lndian cotton16-25 mm
American cotton20-30 mm
Sea Island38-52 mm
Egyptian cotton30-38 mm
Fineness of_cotton fiber:
American= 2.1-2.2 dtex
Egyptian= 1.2-1.8 dtex
Sea Island= 1.0-1.1 dtex ,
Fineness more of immature fibre. So necessary maturity with fineness.
Strength and extension of cotton fiber:
tenacity is 3-3.5g/dtex.
Elastic properties of cotton:
Recovery from deformation of cotton fibre, yarn or fabric from applied load low.
Color of the fibre depends on soil ofgrowth. By adding chemicals soil. color of the cotton fibre varied.
from out side convolution. The twist fibre to be continuous in one direction i.e. if right direction, then left direction. This property of cotton fibers helps in spinning.
Cotton Staple Length:
If the length of fiber 15 longer it spun into finer counts of yarn fetch higher prices. it also gives stronher yarn.
Stronger fibers give stronger Yarns. Further, processing speeds higher higher productivity achieved with less end-breakages.
Finer Fibers produce fmer count of yarn and it also helps stronger yams.
Cotton Fiber Maturity
Mature fibers give better evenness 0f yam. be less end-breakages. Better dye absorbency is additional benefit.
If the ratio is higher. Yam is more even and reduced end-breakages.
Cotton Fiber Elongation
A. better value of elongation will help end-breakages in Spinning and hence higher productivity with low wastage of .
Higher Sugar Content will .create stickiness of fiber processing problem of licking machines.
Cotton Moisture Content
If Moisture Content is standard value of 8.5%, be more invisable loss. lf moisture than 8.5% then be tendency for brittleness of fiber frequent yarn breakages.
If of the Cotton is smooth, be produce more smooth yam which has potential for weaving better fabric.
Cotton having better grade in classing will produce less process waste and yam will have better appearance.
Cotton fiber versatile fibre which has of uses. But the Cotton fibre used on the the wearing cloth like Sweaters, Skirts, Shirts, Swimwear, Kids wear. Blouses, Pants, Hosiery and other dresses.
