Fiber Maturity

Cotton Fiber consists of lumen and cell wall. The maturity index is depends upon the thickness of the cell wall. A fiber is to be considered as ripe when the cell wall of the moisture swollen fiber represents 50-80% of the round cross-section, as unripe when it represents 30-45%, and as dead when it represents less than 25%.
Immature fiber leads to:
1.      Loss of yarn strength.
2.      Neppiness.
3.      High production of short fibers.
4.      Varying dye ability.
5.      Processing difficulties, mainly at the card.
