Some statistical relationships models to predict yarn properties using fiber properties for two categories of Egyptian cotton varieties under two spinning systems [electronic resource].

Includes references.

The present investigations were carried out to determine prediction equation and the relative contribution of six fiber properties to estimate yarn strength, yarn neps and yarn evenness for two categories of cotton varieties (Extra long staple and long staple) under two spinning systems (ring and compact). The full model regression and stepwise multiple linear regression model were used to satisfy the target of work. The results of the supposed models of regression differed according to the category of the used cotton variety and also the applying spinning system. Generally, under ring spinning system, fiber strength and fmeness were the most effective fiber properties to predict yarn properties for the category of extra long staple.
