Terylene wrapped core wire and fabrication method

Abstract

This invention discloses a terylene core-spun thread twisted by two or many terylene core-spun yarns composed of terylene long silk wrapped by terylene short fibers, the process method is as follow: 1) the processed long silks and the short fibers after middle and rear roller drawing are fed into a front roller. 2) the short fibers wrap the long silks in the front roller to become the terylene core-spun yarn to be output from the roller clamp, 3) two or many terylene core-sun yarns are twisted to terylene core-spun threads. The long silk tension is stabilized and controlled by godet hook and a tension disk then to be fed into the front roller after positioning by the carrier rod and the locationing guide wheel.

Description

technical field [0001] The invention relates to a sewing thread applied to a sewing machine, in particular to a high-speed sewing thread and a manufacturing method thereof. Background technique [0002] With the replacement of sewing machines, the machine speed is getting faster and faster, coupled with the popularity of high-grade fabrics, high-speed sewing threads for clothing often require high strength, low coefficient of variation of strength, high twist, few yarn defects, and good seamability. Well, the sewing thread made of polyester staple fiber commonly used in the market can no longer meet the needs of users. It mainly uses the hollow spindle to unwind the yarn for spinning. The disadvantage is that the tension of unwinding will vary with the filament tube The diameter of the unwinding gradually increases as the diameter decreases. In addition, when the filament feeds the roller, the stroke moves with the movement of the short fiber feeding stroke, thus producing p...

[0002] With the replacement of sewing machines, the machine speed is getting faster and faster, coupled with the popularity of high-grade fabrics, high-speed sewing threads for clothing often require high strength, low coefficient of variation of strength, high twist, few yarn defects, and good seamability. Well, the sewing thread made of polyester staple fiber commonly used in the market can no longer meet the needs of users. It mainly uses the hollow spindle to unwind the yarn for spinning. The disadvantage is that the tension of unwinding will vary with the filament tube The diameter of the unwinding gradually increases as the diameter decreases. In addition, when the filament feeds the roller, the stroke moves with the movement of the short fiber feeding stroke, thus producing peeled yarn. In order to meet the needs of the market, a more stable and twist More uniform high-speed sewing thread has been put on the agenda
