Effect of Egyptian cotton fiber length distribution on yarn properties

Abstract EN

In this work studying the effect of AFIS fibre length distribution by weight and by number on combed ring spun yarn properties is carried out.

Where Egyptian cotton fibres of different types and grades were processed for producing combed ring spun yarns with counts ranged from 16Ne to 100 Ne.

Correlation coefficients between yarn properties and fibre length parameters (and slenderness of fibres for yarn neps) were calculated.

Also correlation coefficients between yarn properties and percentages of fibres in the different length categories, by weight and by number, were calculated.

The prediction of yarn properties based on percentages of fibres in different length categories, fibre fineness and immature fibre content was carried out through linear multiple regression analysis.

The contribution of the percentages of fibres in different length categories, immature fibre content (IFC), fibre fineness and yarn count in yarn properties was calculated.

The results showed that fibre length parameters and the percentages of both the shortest and longest fibres have a great influence on yarn properties.

Therefore fibre length distribution data available by AFIS contains information that is useful to spinners.
