Abstract

The invention discloses a spandex yarn controller for flat knitting machines, which comprises a yarn feeding mechanism, a yarn tension adjustment module and a yarn tension detection mechanism which are connected in sequence. The module comprises oppositely arranged support bases, the support bases are connected with a motor, the motors are connected with the groove cylinder, and the support bases are further provided with a controller. The spandex yarn controller of the flat knitting machine of the invention is controlled by a microprocessor unit, can adjust the yarn tension, can effectively control the tension of the fabric, so as to ensure the quality of the fabric woven by the flat knitting machine.

Description

technical field [0001] The invention belongs to the technical field of textile machinery and relates to a spandex yarn controller for a flat knitting machine. Background technique [0002] The flat knitting machine reciprocates when weaving fabrics. Not only does the machine head stop when changing direction, but the yarn feeder also rebounds when changing the direction, resulting in uneven yarn tension and curling, which seriously affects the knitting quality. Traditionally, it is absorbed by the spring system. The tension and length changes of excess yarn can effectively solve the problems of springback, uneven yarn tension and curling when weaving fabrics with low elasticity and elongation. However, in the knitted fabrics woven by knitting machines, in order to increase the stretchability, the elongation rate is relatively large, and there are more and more elastic yarns called elastic threads. The basic material of elastic yarn is spandex, generally polyurethane fiber, ...
