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.

Cotton fiber maturity.

Because of that breeders cotton producers spinners and textile manufacturers. Cotton one of the world s leading agricultural crops is plentiful and economically produced making cotton products relatively inexpensive. 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.

Micronaire can be converted to approximate denier value by dividing micronaire value by 2 82. Fiber strength is closely related to genetic makeup. 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.

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. The amount and pattern of cellulose deposited determines fiber strength and maturity. It is determined by measuring the air permeability of a constant mass of cotton fibers compressed to a fixed volume. Fine or immature fibers that are easily compressed have a lower air permeability and therefore low micronaire.

In other words it is the measure of primary and secondary wall thickness. A unique cotton term related to fiber maturity and fineness diameter. Micronaire however is a unit less value. It s the measurement of airflow resistance through a 2 34 gram fiber specimen that is compressed to a specific volume.
