Production method of combed polyester cotton yarn

A production method and technology for combed cotton, applied in the directions of yarn, textiles and papermaking, can solve the problems of increasing coarse and fine defects in the spinning process, reducing the strength of the roving, increasing the hairiness of the roving, etc., so as to improve the evenness of evenness and the uniformity of coarse and fine details. The effect of improving the yarn strength and improving the yarn quality

Example Embodiment

[0012] 1. preparing combed polyester-cotton yarn with linear density of 18.5tex and JC / T blending ratio of 60 / 40:

[0013] 1. raw material preparation:

[0014] The principle of cotton fiber allocation: picking cotton by hand, with maturity above 0.85, short fiber rate within 13%, foreign fiber content within 0.3g / t and neps within 180 / g..

[0015] The principle of polyester fiber allocation: choose large chemical fiber polyester, the defect content should be controlled within 1mg / 100g, the coefficient of variation of fiber breaking strength should be within 20%, and the dyeing performance of fiber is consistent.

[0016] 2. Opening and cleaning cotton:

[0017] The selected cotton fibers are sequentially grabbed by the FA002 disc picker according to the mixing ratio, and the initial opening and mixing of the cotton fibers are realized in the grabbing process. The grabbed cotton fibers are opened by the A035 cotton opener, and the main mixing effect and auxiliary impurity removal ...

Abstract

The invention discloses a production method of combed polyester cotton yarn, and belongs to the technical field of spinning. Polyester cotton mixed rough yarn and polyester cotton mixed drawn sliversare fed together in a rough yarn process, the acting force of fibers in spun polyester cotton rough yarn is enhanced under the same twisting degree through the stored acting force between the fibers in the fed mixed rough yarn, and therefore, a larger inner friction force field is provided for spinning draft, combed polyester cotton yarn is prepared from the polyester cotton rough yarn through a spinning process, so that the drafting of the polyester cotton rough yarn under the comprehensive control of the large internal friction force field generated by the acting force between the inner fibers of the rough yarn and the external friction force field generated by the friction between a drafting assembly and the rough yarn is realized. Therefore, the yarn forming quality is improved, the yarn evenness and the thick and thin yarn evenness can be improved, and the yarn strength is improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to the production technology of blended yarns. Background technique [0002] The production process of conventional combed polyester-cotton blended yarn is relatively mature. The processing method is that polyester and cotton are made into raw sliver through cleaning and carding processes, and the raw cotton sliver is made into combed cotton through pre-merging and sliver winding processes. Slivers, polyester raw slivers are pre-drawn through the pre-drawing process, and then combed cotton sliver and polyester pre-drawing are mixed in three steps in the drawing process to make roving and spun yarn, and finally the finished product is formed through the automatic winding process. During the process of this process, the fiber straightness in the drawing process is good, and the sliver is relatively unripe, which increases the hairiness of the roving and reduces the streng...
