Technique for spinning blended yarns containing ultralow-ratio antistatic conductive polyester fibers

Abstract

A technique for spinning blended yarns containing ultralow-ratio antistatic conductive polyester fibers belongs to the technical field of textile industry and includes blowing, carding, drawing, rough spinning, fine spinning and spooling procedures. The antistatic conductive polyester fibers are made into card slivers by the blowing, carding and drawing procedures, and each antistatic conductive polyester cotton roll is quantitated into 400-420g/m. In the carding procedure, the card silvers are mixed with pure cotton which is subjected to blowing, blended yarn card slivers containing conductive polyester fibers are spun, the blended yarns containing ultralow-ratio antistatic conductive polyester fibers are produced by double drawing procedures, the rough spinning procedure, the fine spinning procedure and the spooling procedure, and the mass of the antistatic conductive polyester fibers account for 0.5-1.0% of total mass. By using the technique, the problems that the cotton spinning flow is short, semi-finished products are high in quantification, and blended yarns with an ultralow ratio are hard to spin are solved, the blended yarns containing 1% ultralow-ratio antistatic conductive polyester fibers are produced, the requirement of customers on quality is met, and cost is reduced and economic benefit is created for enterprises.

Description

technical field [0001] The invention belongs to the technical field of textile industry production, and in particular relates to a blended yarn spinning process containing ultra-low proportion antistatic conductive polyester fiber. Background technique [0002] The existing cotton spinning process has a short process flow and a large quantity of semi-finished products. It is difficult to add an ultra-low proportion of antistatic conductive polyester fiber to the cotton spinning yarn. Because the antistatic conductive polyester fiber is expensive, when the amount added is large, The cost is high; when the amount added is small, it is not uniform enough and affects the quality. Now it can only be added in a small amount of production, and samples are obtained. It is difficult to produce in large quantities, especially it is difficult to spin blended yarns with an ultra-low proportion of antistatic conductive polyester fiber content below 1%. The yarn prepared from the obtaine...
