[0003] Patent "Processing Method for Spinning Polyester Rotor Yarn" (Application No.: 200710044656.3, Publication No.: 101294323, Publication Date: 2008.08.07) Feed polyester fiber to the carding machine for carding, impurity removal, uniform mixing, transfer On the doffer, it is peeled off by the stripping roller and enters the bell mouth to make quantitative raw sliver; the raw sliver is made into quantitative cooked sliver through the first draw frame and the second draw frame; the cooked sliver is opened by the rotor spinning machine. Loosening, removing impurities, twisting, and winding to produce super polyester rotor yarn; the process is complex and cumbersome with many equipments, which is not conducive to actual production
Combed short-hair fiber has the softness of textile fiber, and the fiber length is generally not more than 30mm (except for a very small amount of fiber), but combed short-hair fiber has good elasticity, natural curl and large static electricity, these characteristics cause fiber rotation. Difficulty in cup spinning

Abstract

The invention discloses a preparing method of a combed undercoat revolving cup yarn. The method includes the steps of undercoat blending, silvering, drawing, stretch breaking, drawing and spinning. The prepared combed undercoat revolving cup yarn has linear density of 51-61 tex. The method is simple in technological process and low in production cost, and the prepared combed undercoat revolving cup yarn has excellent performance.

Description

technical field [0001] The invention belongs to the technical field of textile preparation, and in particular relates to a method for preparing combed short-haired rotor-spun yarn. Background technique [0002] Combed noil is one of the leftover fibers in the process of producing textiles by wool spinning enterprises. Most wool spinning enterprises sell the worsted short wool to woolen spinning enterprises or felting factories at a lower price, and then prepare low-grade worsted short wool textiles. In order to improve the quality and grade of wool spinning products, rotor spinning is performed on combed short wool to improve the quality and wearability of textiles, and at the same time, reduce manufacturing costs. [0003] Patent "Processing Method for Spinning Polyester Rotor Yarn" (Application No.: 200710044656.3, Publication No.: 101294323, Publication Date: 2008.08.07) Feed polyester fiber to the carding machine for carding, impurity removal, uniform mixing, transfer ...
