Abstract
Description
Technical Field
[0001] The invention relates to the field of textiles, in particular to a chenille defect-free stop operation auxiliary device. Background Art
[0002] Chenille yarn, also known as velvet, is a new type of fancy yarn. It is made of two strands of yarn as the core and is spun by twisting the feather yarn in the middle. It has the advantages of high-end luxury, soft hand feel, plump suede, good drape, and particularly good water absorption.
[0003] There are many factors that require the machine to stop during the production of chenille: the core yarn or wool yarn is used up or broken, the yarn channel is not smooth, the machine vibrates or is poorly assembled, and the operation reasons, etc., will cause the yarn to break. A broken end on the chenille machine will cause the next process, that is, the groove drum process, to tie two knots. This knot will not only bring a certain amount of workload to the groove drum worker, but also reduce the quality of the yarn and increase the index of kilometer yarn defects. A shutdown on the chenille machine will also cause a waste of raw materials. When tying knots in the groove drum, the yarn needs to be removed by cutting off the head and tail, which is also a waste of finished products. Therefore, it is necessary to try to reduce the phenomenon of broken ends, but some factors are unavoidable, such as the core yarn or wool yarn raw materials are used up, and the raw materials must be stopped to replace the raw materials. In addition, there are factors such as the broken ends of the core yarn on one side, which cannot be effectively controlled. Once these conditions occur, knots are bound to appear, so new solutions must be studied.
