With the growth of market demand for chemical fiber, polyester production and sales are also increasing, and occupy a large proportion. At present, cotton-type equipment is mostly used in spinning production to process chemical fiber yarn, and there are still many problems in the spinning process. Problem Polyester fiber is a macromolecular polymer with high crystallinity, poor moisture absorption capacity, easy to generate static electricity, and difficult to dye. Due to various factors in the processing process, it is easy to cause bundle yarn, parallel yarn, hard yarn, rubber block, super long, and double Long fiber, during the spinning process, it is easy to cause uneven yarn evenness, undrafting, small braid yarn, rubber yarn, etc.; if the oil agent is not selected properly, it is easy to generate static electricity, causing sticking, entanglement, and card clothing. Stuffing, blockage of drawing bell mouth, entanglement of roller top roller, etc. The factors that cause the supe...
