Research on Sirospun yarn torque using airflow false twisting device

Journal of the Textile Institute, 2013
Yarn torque is one of the most important indexes of yarn quality, which is determined on the mechanical state of the constituent fibers and their configuration in the yarn. The fiber tension within a yarn was proposed to be the most influential factor governing the magnitude of yarn torque by Bennett and Postle. Therefore, the research on Sirospun yarn

Quality Improvement of Sirospun Yarns Through Use of Finer Rovings

Textile Research Journal, 1990
Optimization of Sirospun yam quality is an ongoing process. The compactness of the yam appears to be an important factor. In this paper, we show that for a given yam count, a lower draft produces a stronger and more even yarn.

Structure and Properties of Cotton Sirospun® Yarn

Textile Research Journal, 2000
Cotton Sirospun® yarn has a circular cross-sectional shape, with the two strands segregated and consolidated into an adjacent array. When it is untwisted, the strand twists in an alternate direction. When compared to single yam with the same linear density and twist multiplier, cotton Sirospun yam is superior in tenacity, evenness, hairiness, and ...

Online Detection of Strand Breakage for Sirospun Yarn

Journal of Testing and Evaluation, 2017
Abstract During the Siro-spin process, breakage of one strand arm would cause an extremely serious fabric fault. It is difficult to detect the breakage of one strand arm and give indication for operators. In this research, a kind of photoelectric detection sensor was developed.

The quality of fabric knitted from cotton Sirospun¹ yarn

International Journal of Clothing Science and Technology, 2000
The fine gauge plain weft knitted fabrics knitted from cotton Sirospun1 yarns are more durable and suitable for summer wear. It was found that they have considerable bursting strength, superior abrasion resistance, superior pilling resistance, greater air resistance, cooler hand‐feel and greater thermal conductivity than the fabrics knitted from two ...
