Problems solved by technology

[0005] Based on rotor spinning technology with a rotor speed of 90,000 rpm, the production is 40 s For the above rotor-spun yarn, the design twist of the rotor-spun yarn must be increased by 25% to 30%, resulting in a large decrease in the output of the single machine and a reduction in its spinning efficiency; 25% to 30% lower; in the production process, the breakage rate per thousand ingots is 40 s Twice below, the labor intensity of the workers is high, and the labor cost has little advantage, resulting in the use of rotor spinning to produce 40 s When the above ultra-fine yarn is used, it lacks many advantages, and its economy is restricted by the bottleneck

Abstract

The invention relates to a production method of superfine high count yarn. According to the technology, fiber sequentially goes the procedure of cotton grabbing, dedusting, heavy article impurity removing, cotton opening, cotton condensing, cotton combing, strip combining and rotor spinning yarn. The quality of superfine high count yarn reaches the quality of ring spinning. The production method of superfine high count yarn has the characteristics of high speed, high yield, large coiling block, short technology of rotary spinning, ensures spinning quality and improves the spinning speed at the same time.

Description

technical field [0001] The invention relates to the field of yarn production, in particular to a production method of superfine high-count yarn. Background technique [0002] Spinning technology, born half a century ago, the mainstream spinning technology is mainly ring spinning and rotor spinning. Ring spinning is the most widely used and most common spinning method in the market. The sliver or roving fiber strips after drafting are introduced by the ring traveler, and the winding speed of the bobbin is faster than that of the traveler. , Cotton yarn is twisted to make spun yarn. It is widely used in the spinning engineering of various short fibers. Such as carding, combing and blending, the traveler is driven by the bobbin through the sliver to rotate around the steel ring for twisting. At the same time, the friction of the steel ring makes the speed slightly smaller than that of the bobbin to be wound. ,The shape of the ring-spun yarn is a conical helix in which the fi...
