대환기로 편성한 싱글 져지 대환편성물의 사행도에 관한 연구. II. 사행도의 최소화 방법과 응용

초록

In a previous work, the causes of skewness in single jersey fabric produced on a circular knitting machine were analyzed from two aspects, namely, the machine characteristics and the yarn torsional properties. For practical reasons, the skewness caused by the machine (feeding skewness) could not be reduced, thus making it necessary to control the yarn torsion. One way of counterbalancing the yarn torsion was to alternately feed the Sand Z-twisted yarns into the knitting machine, while another method relied on using Sand Z-twisted single yarns plied together and fed through the same feeder. The results showed that a knit fabric made using plied yarn could reduce skewness. However, the hand is hard and not appropriate for this purpose. The method relying on the combined feeding of S- and Z-twisted yarn could improve the skewness while producing a pleasant touch and appearance. Nevertheless, production costs should be considered. Finally, the method relying on the alternate feeding of S- and Z-twisted yarn produced no skewness. Unfortunately, however, the fabric had a harsh appearance and was unpleasant to the touch. Taking the production costs and fabric properties into account, the use of steam set yarn is thought to offer the most practical solution.
