Spinning device and spinning process for ultra-long ultra-fine polyester yarn

Abstract

The invention relates to a spinning device for ultra-long and ultra-thin spun polyester threads and a spinning process. The spinning device comprises a cotton feeding roller and a cotton feeding support plate, wherein the cotton feeding support plate comprises a vertex-arc plate surface and a skew-back plate surface; a cotton feeding passage is formed between the vertex-arc plate surface and the cotton feeding roller in an included manner; an acupuncture cotton passage is formed between the skew-back plate surface and a licker-in in an included manner; the cotton feeding roller comprises a cotton press roller body, and a left drive shaft and a right drive shaft which are connected with the two ends of the cotton press roller body; the cotton press roller body comprises a cotton press outerbody and an inner chamber formed inside the cotton press outer body; a plurality of mist spray passages are arranged inside the cotton press outer body; each mist spray passage comprises a passage side wall, and an inner passage port and an outer passage port which are connected with the two ends of the passage side wall, the inner passage port is communicated with the cotton press inner chamber,the outer passage port is communicated with the outer wall of the cotton press outer body. Through the design provided by the invention, not only electrostatic phenomena are reduced, ultra-long and ultra-thin fiber production is facilitated, and further the production of sewing threads with high strength and good evenness is facilitated, but also outside interferences are decomposed, and smooth production is ensured.

Description

technical field [0001] The invention relates to a manufacturing process of polyester yarn, which belongs to the field of textile technology, and in particular to a spinning device and a spinning process of super-long and ultra-fine polyester yarn, which is particularly suitable for alleviating static electricity, so as to facilitate super-long and super-fine polyester yarn fiber production. Background technique [0002] Yarn is an essential clothing accessory. The performance of yarn has a great influence on the quality and appearance of clothing. The quality of yarn has a direct impact on the production, appearance and clothing performance of finished products. With the advancement of textile technology, people's pursuit of comfort and high-end clothing is constantly improving, and the research and development of high-quality yarns has received more and more attention. [0003] Compared with other yarns, polyester yarn not only has very high strength, but also has the adva...

AI Technical Summary

Problems solved by technology

However, when the polyester fiber becomes thinner, the electrostatic phenomenon in the polyester yarn processing process will become more serious, resulting in easy winding of the card clothing, rollers, top rollers and other rotating parts, which will affect the existing spinning process, equipment, environment, etc. have made special requests

At present, the commonly used polyester yarn raw materials are polyester fibers with a fineness of 1.67dtex and a length of 38mm. For ultra-long and ultra-fine raw materials, such as fibers with a fineness of 1.33dtex and a length of 51mm, it is difficult to spin them in the existing technology. system
