You asked: Why maturity of cotton is so important in cotton yarn manufacturing?

Why it is important to determine the cotton maturity?

Cotton maturity is a physical testing parameter of cotton fiber properties testing. It is quantified by the degree of cell wall thickening relative to its perimeter. The maturity of individual cotton fiber is an essential aspect of the cotton classing regarding the aesthetics such as appearance, dye-uptake, etc.

Why is fiber maturity important?

Fibre maturity is the key factor affecting the quality of Raw cotton, and it has a substantial impact on rep formation as well as subsequent chemical processing. Process improvements can be made by measuring maturity at different stages of processing.

How the fibre maturity is an important property for the cotton fibre?


The maturity of cotton fibre defines in terms of the development of the cell wall. A fully mature fibre has a developed cell wall. On the other hand, an immature fibre has a very thin cell wall.

What are the effect of cotton fiber maturity on dyeing process?

Laboratory dyeing experiments, carried out with direct dyes on immature and mature cotton fibres of known origin, showed that the maturity did not affect the amount of dye absorbed at equilibrium. The absorption and desorption rates, however, were higher for immature than for mature fibres.

What percentage of cotton regain moisture?

Standard Moisture Regain and Moisture Content of Fibers

Textile Fiber Moisture Regain (MR%) Moisture Content (MC%)
Cotton 8.5 7.34
Jute 13.75 12.1
Viscose 11.0 9.91
Silk 11.0 9.91

How is fiber maturity calculated?

A common measurement used to indirectly infer the fiber’s maturity and fineness is micronaire, a measure of the cotton fiber’s resistance to air flow per unit mass. A fast and precise measurement of micronaire is obtained from high-volume instruments, such as the Uster® High Volume Instrument (HVI).

What are the disadvantages of cotton?


  • Not a very strong fabric.
  • Absorbent – heavy and takes a long time to dry, also stains easily.
  • Poor elasticity so creases badly.
  • Shrinks badly.
  • Highly flammable and burns quickly.
  • Attacked by mildew if left damp.
