Problems solved by technology

[0003] The invention provides an oil agent for post-processing of polyester staple fibers. The technical problem to be solved is that when the oiled fibers are spun by an air-jet vortex spinning process, the main components of the spinning equipment such as vortex tubes and spindles It is not easy to form oil fouling, thereby reducing the possibility of weak twist in the yarn

Abstract

The invention discloses a post-processing oiling agent for a polyester staple fiber. The post-processing oiling agent is an emulsion prepared by active ingredients and water, wherein the active ingredients contain A, B, C and D components. According to parts by weight, when A equals to 1.0, B equals to 0.2-0.8, C equals to 0.5-1.0 and D equals to 1.5-3.0 . When the polyester staple fiber oiled by the post-processing oiling agent is processed by pure spinning through an MVS (Murata vortex spinning) technology, oiling agent scales on main spinning parts such as vortex tubes and spindles in a spinning device are reduced obviously, the defect that the resultant yarn generates weak twist easily is effectively overcome, the cleaning period of the main spinning parts is prolonged and the production efficiency of spinning is improved greatly.

Description

Technical field [0001] The invention relates to a post-processing oil for polyester staple fibers, in particular to a post-processing oil for polyester staple fibers that adopts an air jet vortex spinning process after spinning. Background technique [0002] Air-jet vortex spinning (MVS) is a new generation of spinning technology developed on the basis of traditional air-jet spinning (MJS). When MVS is forming yarn, the sliver is sucked into the vortex tube by the negative airflow, and the fiber rotates at high speed in the tube. The vortex twisting at the free end is realized under the action of air flow. MVS has many advantages such as fast speed, high output, short process and high production rate. Although both MVS yarn and MJS yarn have a double-layer structure of core fiber and wrapping fiber, the yarn forming mechanism of MVS determines that the fiber can be tightly wrapped. Winding, MVS yarn has a much higher percentage of outsourcing fibers, but the number of hairiness ...
