Cotton Fiber Maturity

The amount and pattern of cellulose deposited determines fiber strength and maturity.

Cotton fiber maturity. Immature fibers result in low dye uptake increased fiber breakage fabric defects and waste. Cotton seed hair fiber of several species of plants of the genus gossypium belonging to the hibiscus or mallow family. It is determined by measuring the air permeability of a constant mass of cotton fibers compressed to a fixed volume. Micronaire however is a unit less value.

But since the bolls do not all reach maturity simultaneously an optimum. It s the measurement of airflow resistance through a 2 34 gram fiber specimen that is compressed to a specific volume. Fine or immature fibers that are easily compressed have a lower air permeability and therefore low micronaire. Each day successive layers of cellulose are deposited on the inner surface of the fiber wall in a spiral fashion.

A unique cotton term related to fiber maturity and fineness diameter. Fiber strength is closely related to genetic makeup. Micronaire can be converted to approximate denier value by dividing micronaire value by 2 82. 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.

In other words it is the measure of primary and secondary wall thickness. The micronaire is a measurement of fiber fineness and maturity. A cotton fiber is like a hollow tube. 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.
