Cotton Fiber Maturity

Micronaire can be converted to approximate denier value by dividing micronaire value by 2 82.

Cotton fiber maturity.

Immature fibers result in low dye uptake increased fiber breakage fabric defects and waste. 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. 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.

The amount and pattern of cellulose deposited determines fiber strength and maturity. A cotton fiber is like a hollow tube. 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. Fiber strength is closely related to genetic makeup.

Cotton seed hair fiber of several species of plants of the genus gossypium belonging to the hibiscus or mallow family. Cotton one of the world s leading agricultural crops is plentiful and economically produced making cotton products relatively inexpensive. The micronaire is a measurement of fiber fineness and maturity. But since the bolls do not all reach maturity simultaneously an optimum.

In other words it is the measure of primary and secondary wall thickness. Because of that breeders cotton producers spinners and textile manufacturers. A unique cotton term related to fiber maturity and fineness diameter. 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.
