A kind of production method of pure cotton high-count yarn

Abstract

The production method of a cotton cotton high yarn provided by the present invention uses a long velvet cotton with a fiber diameter of less than 10.5 microns as the raw material to achieve a spinning yarn of 170 to 330 high yarn;In the second coarse yarn, a dual -hole cotton collector with a hanging ingot and a 3mm hole spacing realizes the small fixed -volume spinning of the coarse yarn;The cotton is fed between the fourth Rogla and the fourth leather roller; the two coarse gauze strips are pre -entered into the bidth cotton collector and fed it into the third epithelium roller and the epithelial ringThe main extension of the lower skin ring; the dual -hole cotton collector controls the direction of the two coarse gauze feeding in the main extension area to ensure that the two coarse gauze strips are not crossed and overlap;In the second, third Ralla and upper and lower skin rings, they are extended and co -authored in the main leading area;After extending the area, twist the coarse gauze, cover it around the coarse gauze to form a second coarse gauze.

Description

Technical field [0001] The invention relates to the technical transformation of spinning, and is especially suitable for the spinning of pure cotton yarns of J170S-J330S. It breaks through the spinning technical problems of traditional high-count yarns and realizes the technical effects of increasing production and maintaining quality. Background technique [0002] For spinning high-count pure cotton yarns of more than 170S, modern spinning equipment and technology are difficult to solve the breakage of spinning, winding, and doubling processes. The reasonable distribution of drafting in each process before spinning can fully eliminate impurities, short lint and Technical difficulties such as neps. The ultra-high count yarn of 170S and above has a very thin diameter, and the number of fibers contained in a single yarn is relatively small, only 11-15. The yarn strength is extremely low, and there are many breaks during spinning. It adopts traditional production The method has be...

AI Technical Summary

Problems solved by technology

[0002] Spinning pure cotton high-count yarn above 170S, modern spinning equipment and technology are difficult to solve such as yarn breakage, winding, doubling process, reasonable distribution of draft in each process of pre-spinning, fully eliminate impurities, short fibers and Neps and other technical difficulties

The ultra-high count yarn above 170S has a very thin diameter, and the number of fibers contained in a single yarn is relatively small, only 11 to 15. The yarn strength is extremely low, and there are many broken ends during spinning. The method has been unable to achieve normal spinning; according to the spinning requirements, the roving weight required for spinning high-count pure cotton yarn with more than 170 counts is in the range of 1.10-1.5g / 10m, so it is difficult to achieve such a small weight roving with normal production technology
