Evaluation of Properties of Spun-like Yarns

Abstract

Some properties of our newly developed spun-like nylon yarn and fabrics called“Trim”were evaluated and compared with those of conventional false twist yarns spun yarns and so on.
It was proved that“Trim”could keep suitable roughness, irregu-larity and bulkiness even when stretched, which are essentially needed for spun-like yarns.
Further more features, physical and functional properties of some fabrics were tested. In the evaluation of physical properties, spun-like yarn was defined to have small deviations in results of tests on 14 physical proper ties authorized in KES-F system compared with polyester cotton blended broad cloth and knitted fabrics of cotton.
It was found that“Trim”fabrics had antiglaze surface and high bulkiness, and that the deviations described above were very small. Consequently, “Trim”fabrics were more improved in its functional properties such as insulation and moisture absorption than the fabrics of conventional synthetic fibers.
