Cotton Fiber Maturity

It s the measurement of airflow resistance through a 2 34 gram fiber specimen that is compressed to a specific volume.

Cotton fiber maturity.

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. A unique cotton term related to fiber maturity and fineness diameter. Cotton seed hair fiber of several species of plants of the genus gossypium belonging to the hibiscus or mallow family. Fiber strength is closely related to genetic makeup.

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. A cotton fiber is like a hollow tube. 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. Immature fibers result in low dye uptake increased fiber breakage fabric defects and waste.

Fine or immature fibers that are easily compressed have a lower air permeability and therefore low micronaire. Micronaire however is a unit less value. Each day successive layers of cellulose are deposited on the inner surface of the fiber wall in a spiral fashion. Cotton one of the world s leading agricultural crops is plentiful and economically produced making cotton products relatively inexpensive.

Micronaire can be converted to approximate denier value by dividing micronaire value by 2 82. The micronaire is a measurement of fiber fineness and maturity. Because of that breeders cotton producers spinners and textile manufacturers. It is determined by measuring the air permeability of a constant mass of cotton fibers compressed to a fixed volume.
