Processing equipment for high-strength air-jet vortex spinning yarn

Abstract

The invention discloses processing equipment for a high-strength air-jet vortex spinning yarn. The processing equipment comprises a yarn outlet device, a slivering machine, an air-jet vortex cavity, rollers and a hot roller, wherein two pairs of rollers are arranged, respectively traction rollers and output rollers; low melting point fibres and common fibres are respectively led out from the yarnoutlet device; and the low melting point fibres and the common fibres pass through the slivering machine, the air-jet vortex cavity, the traction rollers, the hot roller and the output rollers and arewound to complete cone yarn after being mixed and made into strips. According to the processing equipment for the high-strength air-jet vortex spinning yarn, the low melting point fibres and the common fibres are output controllably by arranging the yarn outlet device; contact adhesion of the low melting point fibres and polyester fibres is realized through the processing mode of air-jet vortex spinning after the low melting point fibres and the common fibres are mixed; through the cohesion among the common fibres, the cohesion force of the produced yarn is greatly increased; and the yarn ismore difficult to disintegrate, so that the frictional adhesion force among the fibres is increased, and the strength and the wear resistance of the yarn are improved.

Description

technical field [0001] The invention relates to the technical field of air-jet vortex spinning yarns, in particular to processing equipment for high-strength air-jet vortex spinning yarns. Background technique [0002] Synthetic fiber is a chemical fiber made from artificially synthesized linear polymers with suitable molecular weight and soluble (or meltable) properties through spinning and post-processing. The current conventional technical means on the market are: Air-jet vortex spinning uses compressed air to form a high-speed rotating air field inside the vortex cavity, separates, condenses, and strips the single fiber after drafting, and twists the free end of the fiber into yarn; [0003] Although the air-jet vortex spinning yarn can avoid the problem of easy fluffing and pilling, the cohesion between the fibers is not enough in the process of producing synthetic fibers through the air-jet vortex spinning yarn alone, and the yarn is easy to disintegrate, resulting in ...

Problems solved by technology

[0003] Although the air-jet vortex spinning yarn can avoid the problem of easy fluffing and pilling, the cohesion between the fibers is not enough in the process of producing synthetic fibers through the air-jet vortex spinning yarn alone, and the yarn is easy to disintegrate, resulting in synthetic fibers. Yarn products have low friction and adhesion, which affects the increase of yarn strength and wear resistance
