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.

Air-Jet Texturing of Sirospun Yarn

Textile Research Journal, 1992
Sirospun yarns have been texturized using an air-jet process to improve the bulk of the parent yarn. The study examines the effects of twist in the parent yarn, as well as overfeed and air pressure during texturing on the properties of the textured yarn. When suitable process parameters are chosen, Sirospun yarns lend themselves to excellent texturing

The Effect of Testing Speed on the Hairiness of Ring-spun and Sirospun Yarns

Journal of the Textile Institute, 1997
This paper examines the effect of testing speed on yarn-hairiness results. The number of hairs in different length groups and the S 3 values are considered in this study.

Effect of Strand Spacing and Twist Multiplier on Cotton Sirospun Yarn

Textile Research Journal, 1998
For combed cotton yarns, the wider the strand spacing is in Sirospun, the better the yarn properties are in terms of tenacity, Uster hairiness, abrasion resistance, and trapped strand twist.

Investigation of the fastness properties and color values of cotton fabrics knitted from ring spun and Sirospun^®yarns

Journal of the Textile Institute, 2011
Sirospun yarn production is a new approach to produce two‐folded and twisted yarns. This method integrates the spinning and folding action in a single step. Therefore, it may have some important advantages such as simplicity of the process, lower production costs, lower investment, space saving, etc.

Research on yarn qualities modified by mechanical false-twisting device

Journal of the Textile Institute, 2020
In the ring-spinning process, the area between the front roller nip and twisting point is spinning triangle, and its geometry influences the fiber tension distribution in the spinning triangle directly and determines the properties of spun yarns ...

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 ...
