Cotton Fiber Maturity

Cotton fiber maturity degree of secondary cell wall thickening relative to the perimeter is one of the most important fiber quality and processing parameters of cotton.

Cotton fiber maturity. The fibre maturity is usually estimated by several indirect tests which are foten used to find out the proportion of fibres containing a maturity greater. It is determined by measuring the air permeability of a constant mass of cotton fibers compressed to a fixed volume. Cotton one of the world s leading agricultural crops is plentiful and economically produced making cotton products relatively inexpensive. Each day successive layers of cellulose are deposited on the inner surface of the fiber wall in a spiral fashion.

But since the bolls do not all reach maturity simultaneously an optimum. Cotton seed hair fiber of several species of plants of the genus gossypium belonging to the hibiscus or mallow family. Immature fibers result in low dye uptake increased fiber breakage fabric defects and waste. A unique cotton term related to fiber maturity and fineness diameter.

Fiber strength is closely related to genetic makeup. The micronaire is a measurement of fiber fineness and maturity. Fine or immature fibers that are easily compressed have a lower air permeability and therefore low micronaire. Definition of fiber maturity fibre maturity in case of cotton fiber is a fibre characteristic which expresses the relative degree of thickening of the fibre wall.

Micronaire can be converted to approximate denier value by dividing micronaire value by 2 82. The amount and pattern of cellulose deposited determines fiber strength and maturity. Because of that breeders cotton producers spinners and textile manufacturers. Micronaire however is a unit less value.
