What is Fibre Maturity & What Factors Work Behind to Fiber Maturity in Textile

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. In other words, it is the measure of primary and secondary wall thickness.
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 than some selected level.

A fiber will be matured if a high degree of wall thickening took place into the fiber content during cotton growth.

Things upon Which the Textile Fiber Maturity Depends

There are several factors upon which the fibre maturity is basically depends. By changing theses factors you can also measure that which factors is working behind to be a fibre matured or which not.
The factors are –

1. Weather: If the weather doesn’t favor, the fiber gets less chance to be matured.
2. Types of Soil: It is proved that, in some country the fibers grows well and becomes well matured and on some other country; due to the soil, fibers don’t be so much matured and grows low quality fibres.
3. Plant Diseases: If proper care is not taken to the fibres, these become less matured due to several diseases.
4. Pests: Some pests is good for Plants and some are bad. So be careful to apply any pesticides on any plants.
5. Dead Fibers: It is natural that the dead fibers will be immature.

I hope you have got a basic idea about Fiber Maturity and you have also learned that what are the factors works behind to make a fiber immature.
Is there anything I have missed to mention? Please add these in the comment box if you know something more about Textile Fibre Immaturity.
