Spinning system and using method of regenerated polyester yarn

Abstract

The invention discloses a spinning system for a regenerated polyester yarn. The spinning system comprises a cotton feeding roller, a carding machine and a sliver can, wherein a cotton feeding pallet is arranged below the cotton feeding roller; the cotton feeding pallet comprises a vertex-arc plate surface and a skew back plate surface; a cotton feeding channel is sandwiched between the vertex-arcplate surface and the cotton feeding roller; a cotton puncturing channel is sandwiched between the skew back plate surface and a licker-in roller; the cotton feeding channel communicates with an inletof the sliver can after sequentially passing through the cotton puncturing channel, a cylinder and a doffer; an outlet of the sliver can communicates with a drawing frame after sequentially passing through a guide roller and the cotton feeding roller; the guide roller communicates with the cotton feeding roller through a horizontal pallet; a plurality of air flow nozzles are arranged in a horizontal pressure plate parallel to the horizontal pallet and directly arranged above the horizontal pallet; the cotton feeding roller comprises a cotton pressing outer body and a cotton pressing inner cavity formed therein; a plurality of spray channels are formed in the cotton pressing outer body. The spinning system not only can slow down a static phenomenon, but also facilitates the production of ultra-long and super-fine regenerated polyester fibers, and can decompose external interferences and adjust the humidification amount.

Description

technical field [0001] The invention relates to a manufacturing process of ultra-long and ultra-fine regenerated polyester yarn, which belongs to the field of textile technology, and particularly relates to a spinning system and a use method of regenerated polyester yarn, which is specifically suitable for slowing down static electricity, so as to facilitate ultra-long and super Production of fine recycled polyester yarn. 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. In terms of material types, yarn can be divided into pure cotton yarn, ch...

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
