The Solutions for Controlling Fabric Barré
Apr 4, 2019
Spinning mills have many options in the raw material they purchase for producing yarns. This expansion in the availability of raw material has helped to reduce cost and to improve yarn quality and spinning efficiency. Traditionally, purchased cottons had well established seed varieties and growth regions. This resulted in few dying and finishing problems by controlling the average micronaire. Over the past few years, there has been a rapid increase in the problems with dying and finishing, especially for 100% cotton knitted fabrics. Fabric barré and white speck neps are two of the problems that spinning mills that use cottons from different growth areas face. Mixing cottons by the average micronaire does not give the necessary control for eliminating these costly defects. Mills experiences and trials have provided the necessary information to set up guidelines for controlling fiber properties that influence the dyability of cotton yarns in knitted fabrics. There are several mechanical causes that can also influence the dying of fabrics. This paper offers several solutions for controlling the key fiber properties that cause barré in fabrics.
