Problems solved by technology

The biggest problem with this spinning method is that it cannot effectively solve the normal mass production of hemp drugs in cotton spinning in an environment with a humidity exceeding 80%, and it cannot effectively solve the problem of hemp knots. The technical research on hemp knots has always been an important issue in cotton spinning

Embodiment

[0035] A kind of preparation method of cotton hemp acrylic fiber blended yarn, comprises the steps:

[0036] (1) Hemp opening: The hemp fiber enters the opening machine for processing, and the beater speed of the opening machine is 600 rpm.

[0037] (2) Hemp pretreatment: Hemp fibers are modified for moisture regain, specifically: mixed with crude oil, antistatic agent (commercially available) and warm water to form a moisture regain modified liquid, and the moisture regain modified liquid is evenly added to the hemp fiber to regain moisture. Add warm water to make the moisture regain of the hemp fiber reach 24%, and let it stand for 24 hours; based on 100kg of hemp fiber, the dosage of each component in the moisture regain modification liquid is: 0.8kg of crude oil, 0.2 kg of antistatic agent, warm water 11 kg; the water temperature of warm water is 40-45 °C.

[0038](3) Raw sliver preparation for the initial delineation of hemp acrylic fiber: the hemp fiber and acrylic fibe...

Abstract

The invention discloses a preparation method of cotton hemp acrylic blended yarns. The preparation method comprises the following steps of (1) performing hemp loosening; (2) performing hemp pretreatment; (3) performing unprocessed strip preparation from hemp acrylic fibers by carrying out primary removal of hemp knots; (4) performing cotton unprocessed strip preparation; (5) performing unprocessedstrip preparation from hemp acrylic fibers by carrying out secondary removal of hemp knots; (6) performing head combination; (7) carrying out secondary combination and tail combination; (8) performing rough yarn forming; (9) performing fine yarn forming; and (10) finally adopting an automatic winder to form yarns and remove yarn faults to form a cylinder of blended yarns. The method disclosed bythe invention has the advantages that the hemp knot is low in the formed hemp fibers, and the problem of hemp knot of the hemp variety and the problem of hole breaking of the cloth surface are fully solved.

Description

technical field [0001] The invention relates to the technical field of fiber production, in particular to a method for preparing cotton, hemp and acrylic blended yarn. Background technique [0002] Hemp fiber is the softest kind among all kinds of fibers, its fineness is only one-third of that of ramie, equivalent to that of cotton fiber, and the top of the fiber is blunt and round, without the sharp top of ramie and flax. Therefore, the finished product is particularly soft and suitable for the body. The slender cavity in the center of the hemp fiber and the longitudinal distribution of many cracks and small holes on the fiber surface form an excellent capillary effect, so the perspiration and moisture absorption are good. Both cotton and wool are complex, with irregular triangles, hexagons, flat circles, waist circles, etc. The cavity and shape are different, and its molecular structure is polygonal, loose, and has spiral patterns. Therefore, the hemp fiber has a good dis...
