Super high pure cotton yarn and production method thereof

Abstract

The invention provides a super high pure cotton yarn and a production method thereof. The physical indexes of the raw cotton fibre adopted by the super high pure cotton yarn are as follows: the fiber length is 38-40 mm, the bearded mote is less than 500 cnt / g, the Micronaire is 3.3-3.5 mu g / inch<2>, the neatness is more than 88%, the fibre fineness is more than 130 dtex, the brute force is more than 40 CN / tex, the elongation is more than 6.8%, the flock rate is less than 6.5%, the nep is less than 120 cnt / g, the length variation coefficient (CV) is less than 30%, the mature fibre is more than 85%, and the immature fibre is less than 5%. The pure cotton yarn of 180-200 Ne is spun. The invention solves the problem that super high cotton yarn is hard to spin by the fine control and process setting of the physical indexes of the raw cotton, and the prepared super high pure cotton yarn has the characteristics of bright and even cloth surface, soft, stiff and smooth feel, light, fine and smooth texture and the like.

Description

technical field [0001] The invention relates to an ultra-high-count all-cotton yarn and a production method thereof, in particular to an ultra-high-count all-cotton dyed yarn and a production method thereof. Background technique [0002] High-count pure cotton dyed yarn is the development direction of textile products in recent decades. Pure cotton high-count dyed yarn fabric is the basis of modern elegant and expensive clothing. With the application of nanotechnology in the textile field, people no longer regard the combed 100S and the produced fabrics as rare treasures. The higher goal and direction is to advance the pure cotton high-count yarn to 180S and above, so as to bring textile technology The innovation and development of the technology will gradually change people's old ideas about fashion trends, guide and inspire people to think about the development and production of ultra-high-count dyed yarn (above 180S) and the production and development of extra-high-count dy...

AI Technical Summary

Problems solved by technology

[0003]For combed 180S~200S pure cotton dyed yarn, the neps, fiber seed crumbs and impurities in the raw cotton will cause great harm during the spinning process. This is an obstacle in the manufacturing process of combed 180S-200S roving, spun yarn, and winding. On the one hand, it is unfavorable to the control of drafting. , The production of wrapping rollers, the broken end rate increased sharply, in the raw material requirements of combed 180S-200S pure cotton dyed yarn, for the short-staple rate, the fiber below 28mm must be regarded as the fiber of the pair-spun combed 180S-200S pure The short fibers in the cotton dyed yarn raw materials are beneficial to the production of its cotton yarn. We cannot use the traditional raw material attribute standards as a basis for guidance. Only the physical indicators of raw cotton can be formulated according to the needs of combed 180S-200S pure cotton dyed yarn. , is conducive to the smooth completion of spinning
