Cotton Fiber Maturity

Cotton seed hair fiber of several species of plants of the genus gossypium belonging to the hibiscus or mallow family.

Cotton fiber maturity.

Cotton one of the world s leading agricultural crops is plentiful and economically produced making cotton products relatively inexpensive. A unique cotton term related to fiber maturity and fineness diameter. Because of that breeders cotton producers spinners and textile manufacturers. A cotton fiber is like a hollow tube.

Each day successive layers of cellulose are deposited on the inner surface of the fiber wall in a spiral fashion. Micronaire however is a unit less value. The amount and pattern of cellulose deposited determines fiber strength and 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.

In other words it is the measure of primary and secondary wall thickness. Fine or immature fibers that are easily compressed have a lower air permeability and therefore low micronaire. It is determined by measuring the air permeability of a constant mass of cotton fibers compressed to a fixed volume. 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.

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. Immature fibers result in low dye uptake increased fiber breakage fabric defects and waste. The micronaire is a measurement of fiber fineness and maturity. It s the measurement of airflow resistance through a 2 34 gram fiber specimen that is compressed to a specific volume.
