Cotton Fiber Maturity

The micronaire is a measurement of fiber fineness and maturity.

Cotton fiber maturity. Cotton seed hair fiber of several species of plants of the genus gossypium belonging to the hibiscus or mallow family. Micronaire however is a unit less value. 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. 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.

Because of that breeders cotton producers spinners and textile manufacturers. A cotton fiber is like a hollow tube. Fine or immature fibers that are easily compressed have a lower air permeability and therefore low micronaire. A unique cotton term related to fiber maturity and fineness diameter.

In other words it is the measure of primary and secondary wall thickness. Fiber strength is closely related to genetic makeup. Micronaire can be converted to approximate denier value by dividing micronaire value by 2 82. Immature fibers result in low dye uptake increased fiber breakage fabric defects and waste.

Each day successive layers of cellulose are deposited on the inner surface of the fiber wall in a spiral fashion. But since the bolls do not all reach maturity simultaneously an optimum. Cotton one of the world s leading agricultural crops is plentiful and economically produced making cotton products relatively inexpensive. The amount and pattern of cellulose deposited determines fiber strength and maturity.
