Some. Structural and Physical Properties of Yarn Made on the Integrated Composite Spinning System

Abstract

One of the recent systems of yarn production is the Bobtex Integrated Composite Spinning (ICS). The process which produces a composite yarn that utilizes a polymer substrate with a fibrous surface. The production of this system ranges between 165 and 330 yd/min. The yarn used in this investigation was a two-component yarn, one of the early structures developed, which was found to have some favorable characteristics as well as some drawbacks. Work is going on to extend the study to the newer developments which have led to the production of three-component yarns.

This paper presents a microscopical study of the yarn cross section which reveals the mechanism of binding the outer fibers to the polymer matrix. A small sample of woven fabric was microscopically analyzed and a cross section of the fabric is shown. Also, some of the physical properties were determined and the results are discussed.
