Embodiment 1

[0031] Embodiment 1: to produce 5.83tex (100 S ) AB yarn as an example. Raw cotton: For A roving, select long-staple cotton with a fineness of 1.42dtex, a main body length of 37.2mm, a short staple rate of less than 20mm of 4.3%, a breaking strength of 37.6cN / tex, a breaking elongation of 7.9%, a micronaire value of 3.9, and a uniformity of 78.7 %; Wool fiber is selected from cashmere with an average length of more than 36mm and a short cashmere rate of less than 25mm.

[0032] The specific process steps are as follows:

[0033] For a roving:

[0034] (1) Pretreatment

[0035] Dye the long-staple cotton fiber into yellow; dye the cashmere fiber into red, then weigh, inspect and shred, and then spray with antistatic agent and oil agent mixed with crude oil 999R / P, and put it in 28 Hour.

[0036] (2) Open and clean cotton

[0037] Adopt FA106 cotton opener, for long-staple cotton fiber, the beater speed is 475r / min, the distance between the cotton feeding roller and the be...

Abstract

The invention discloses four-roller ultra-large drafting siro spinning AB yarns, which are characterized in that A coarse yarns comprise 50% weight percent of Xinjiang long stapled cotton and 50% weight percent of cashmere fibers; and B coarse yarns comprise 55% weight percent of viscose, 20% weight percent of chinlon and 25% weight percent of bamboo fibers. A production method for the four-roller ultra-large drafting siro spinning AB yarns comprises the steps of feeding the A and B coarse yarns, processed and machined according to a ratio, into rear rollers by a dual-horn port, and obtaining the four-roller ultra-large drafting siro spinning AB yarns through four-roller three-area ultra-large drafting. The four-roller ultra-large drafting siro spinning AB yarns and the production method thereof can comprehensively utilize excellent properties of various fibers, realize the excellent comfort and antibacterial function of the blending yarns, realize the multifunctional demands of the yarns, and meet actual demands; and meanwhile, the ultra-large drafting is realized by adopting the four-roller four-leather ring three-area drafting, thus improving the spinning suitability and the finished yarn quality of the yarns.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a four-roller ultra-large draft Siro spinning AB yarn and a production method thereof. Background technique [0002] With the development of social economy and the improvement of people's living standards, people's consumption concepts are constantly updated, and they pay more and more attention to the quality of life and living environment. The functional requirements of clothing are getting higher and higher, especially for clothing antibacterial, The requirements for health care, feel, quality and other aspects are constantly improving. On the other hand, with the continuous increase of market competition and the gradual increase of investment in the structural adjustment of my country's textile industry, in order to improve the added value of products and market competitiveness, yarn varieties are gradually developing in the direction of high branching and different...
