WOOL FIBER AS A RAW MATERIAL FOR BLENDED YARN

Abstract

The article presents the characteristics of wool fibers and raw
materials for the production of bicomponent yarn. This article discusses
the development of new types of yarn that are raw materials for woven
and knitted products. The purpose of the research is to select silk and wool
fibers according to technological parameters, and obtain bicomponent
yarn. In the production of yarn, the fineness of the fibers, the degree of
their contamination and the degree of extraction of pure fiber are of great
importance; these indicators are determined experimentally. The properties
of wool fibers of four different degrees of coarseness used as raw materials
after washing are determined. The suitability of wool fibers for mixing with
staple yarn and silk fibers is determined. The effect of fiber content on the
strength of the yarn is theoretically calculated. It turns out that natural silk,
which has a low linear density, increases the friction forces between wool
fibers and gives products made from it a silky, shiny appearance. The optimal
value of the proportion of silk fibers in the yarn is determined depending on
its strength
