Production method of nylon fluff for flocking

Abstract

The invention discloses a production method of nylon fuzz for flocking. The production method comprises the following steps: conducting slicing and blend spinning on 5-8 parts by weight of PA black master batch and 92-95 parts by weight of PA6 to prepare PA black silk flocks, and then cutting the PA black silk flocks into black fuzz, wherein the PA black master batch consists of the following components: 30-40 parts by weight of carbon black, 3-5 parts by weight of an auxiliary and 67-55 parts by weight of PA6. According to the production method for nylon fuzz for flocking, the specific PA black master batch is used, coloring is conducted before spinning, the original post-dyeing process method is replaced, the conventional PA black master batch spinnability problem can be solved, the flaws can be reduced, the fiber blackness can be improved, the period of a spinning assembly can be prolonged, the service cycle of a fiber cutter can be prolonged, and the finally prepared black fuzz can be used for electrostatic flocking.

Description

technical field [0001] The invention relates to a production method of nylon fluff for flocking. Background technique [0002] The production of nylon fluff for flocking is to use PA natural fiber to cut into fluff, then dye, rinse, conduct conductive finishing, dry and sieve to obtain black fluff. Among them, the technology of the dyeing process is restricted by increasingly strict environmental protection requirements, and the processing cost is high. However, some PA black masterbatches in the prior art have poor spinnability when spinning PA black fibers, many defects, insufficient fiber blackness, too short spinning assembly cycle, frequent replacement, and short fiber cutter replacement cycle. Contents of the invention [0003] The purpose of the present invention is to provide a production method of nylon fluff for flocking, which uses specific PA black masterbatch and is colored before spinning, which can replace the original post-dyeing process, and can also solv...

Problems solved by technology

[0003] The purpose of the present invention is to provide a production method of nylon fluff for flocking, which uses specific PA black masterbatch and is colored before spinning, which can replace the original post-dyeing process, and can also solve the problem that the existing PA black masterbatch can be spun To reduce the problem of sex, reduce defects, improve fiber blackness, prolong the cycle of spinning components, prolong the life cycle of fiber cutter, and the final black fluff can be used for electrostatic flocking
