Method for producing regenerated cellulose fiber yarn

Abstract

The invention discloses a method for producing regenerated cellulose fiber yarn, comprising the steps of: (1) cotton opening and cleaning; (2) cotton carding; (3) drawing; (4) roving; (5) spinning; and (6) spooling, wherein a cotton carder is applied in the step of cotton carding; the cotton carder comprises a cotton carder body, and a licker-in, a cylinder and a doffer which are rotatably arranged on the cotton carder body in order; teeth are arranged on the surface of the licker-in, pins are distributed on the surface of the cylinder and pins are distributed on the doffer; a small under screen is arranged between the licker-in and the cylinder; a top cover board, a front cover board and a rear cover board are arranged at the upper part and the front and rear sides of the cylinder; teeth are arranged on the top cover board, the front cover board and the rear cover board; the distance between the licker-in and the cylinder is 0.175 mm; the distance between the cylinder and the doffer is 0.125 mm; the distance between the licker-in and the inlet of the small under screen is 3 mm; and the distance between the licker-in and the outlet of the small under screen is 0.5 mm. The dry and wet strengths of the fiber yarn produced by the method of the invention are enhanced, and the fiber yarn is suitable for the water-jet looms.

Description

technical field [0001] The present invention relates to a method of spinning, and more particularly to a method of producing regenerated cellulose fiber yarn. Background technique [0002] The wet strength of the regenerated cellulose fiber yarn produced by the traditional process is very low, the difference between dry and wet strength is huge, the hairiness is high, and it is easy to stick. , water-jet looms have been popularized and used, and the above-mentioned fiber yarns are prone to sticking and entanglement in the weft feeder due to their hairiness, making it difficult to unwind, and the weight of the regenerated cellulose fiber yarn increases significantly after absorbing water, and the flight resistance In view of the above-mentioned technical deficiencies, it is imminent to introduce a new method for producing regenerated cellulose fiber yarn. Contents of the invention [0003] The object of the present invention is to provide a method for producing regenerated...
