Problems solved by technology

Usually, the twist coefficient of cotton yarn for knitting is 280-360, and the twist coefficient of cotton yarn for weaving is 290-430. When the twist coefficient of cotton yarn is lower than 280, it is a special low-twist yarn. According to the current In the ring spinning process, in the spinning section of the spinning process, the dynamic strength of the low-twisted yarn drops sharply, which causes the dynamic tension of the yarn in the spinning section to be greater than its dynamic strength, which in turn causes yarn breakage and makes it difficult to continue production
In addition, when the twist of the yarn is reduced, its quality indicators such as yarn strength and hairiness will deteriorate

Abstract

The present invention provides a spinning process, yarn and fabric of silk-soft spun soft yarn. The spinning process includes: opening and cleaning process, carding process, combing process, drawing process, roving process, spinning process and winding process. In the spinning process, the spinning frame feeds two rovings at the same time, which are drawn and twisted and then wound into a spinning bobbin. The bobbin weight is 40-60g, the spindle speed is 8000-12000r / min, and the twist direction is S. Twist with a twist factor of 220‑280 and a total draft of 39‑52. The yarns prepared by using the spinning process of the present invention have improved softness, surface finish and dye uptake of fabrics, and the fabrics are soft, fluffy, uniform and fine, and have good gloss.

Description

technical field [0001] The invention relates to the field of spinning, in particular to a spinning process, yarn and fabric of silk-soft spinning soft yarn. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the wearing comfort of clothing. Among them, the pursuit of "softness" of fabrics is a major theme. In order to achieve "softness", in addition to the commonly used softness treatment of fabrics, the industry also puts forward new requirements for the twist of yarns: use yarns with as low twist as possible to obtain fabrics with good "softness" . Usually, the twist coefficient of cotton yarn for knitting is 280-360, and the twist coefficient of cotton yarn for weaving is 290-430. When the twist coefficient of cotton yarn is lower than 280, it is a special low-twist yarn. According to the current In the ring spinning process, in the spinning section of the spinning process, the dynamic strength of the ...
