Cotton Fiber Maturity

A cotton fiber is like a hollow tube.

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 one of the world s leading agricultural crops is plentiful and economically produced making cotton products relatively inexpensive. In other words it is the measure of primary and secondary wall thickness. Micronaire can be converted to approximate denier value by dividing micronaire value by 2 82.

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. Each day successive layers of cellulose are deposited on the inner surface of the fiber wall in a spiral fashion. The amount and pattern of cellulose deposited determines fiber strength and maturity. 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. It s the measurement of airflow resistance through a 2 34 gram fiber specimen that is compressed to a specific volume. The micronaire is a measurement of fiber fineness and maturity. It is determined by measuring the air permeability of a constant mass of cotton fibers compressed to a fixed volume.

A unique cotton term related to fiber maturity and fineness diameter. Micronaire however is a unit less value. Immature fibers result in low dye uptake increased fiber breakage fabric defects and waste. Because of that breeders cotton producers spinners and textile manufacturers.
