A kind of mechanical compact spinning method

Abstract

The invention relates to a mechanical type compact spinning method. A friction device is arranged above a sliver in a condensed area formed between a compact-ring-spinning-frame front-roller output jaw and a twisting triangular space, the distance between a frictional part on the surface of the friction device and a lattice apron is smaller than the thickness of the silver; in the spinning process, the friction device does continuous movement, the grooving direction of a condensed groove is located between the opposite direction of the movement direction of the friction device and the operation direction of the silver, the grooving direction of the condensed groove is the extending direction, from the groove end A to the groove end B, of the condensed groove, and the silver keeps close to the groove end A to the groove end B in sequence in the operation process. Compared with a traditional compact spinning method, required negative pressure gas flow is small, the energy consumption of compact spinning is greatly reduced, and the production cost is saved, due to the wrapping effect of outer-layer fibers, the spinning strength is high, the quality of spinning yarn is good, and the method has an extensive application prospect.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a spinning method, in particular to a mechanical compact spinning method. Background technique [0002] Compact spinning is a new spinning technology developed on the basis of traditional ring spinning in recent years. Compact spinning not only maintains the original advantages of ring spinning, but also significantly improves the quality and grade of yarn, especially in terms of yarn hairiness and strength, so this technology is rapidly promoted at home and abroad. Since the Paris International Machinery Exhibition in 1999, Reiter has exhibited the ComforSpin (comforspin) compact spinning device developed by Fehrer's dust cage principle, and the Elite Spinning developed by Sussen and Zinser by using the Artzt principle of the Denkendor Textile Technology Research Institute. Since the Compact3 compact spinning device, the compact spinning technology has been popularized and applie...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is in order to overcome above-mentioned deficiency in the prior art, utilize external mechanical action force to replace air flow action force, carry out auxiliary twisting to the gathering area between the front roller output nip and the twisting triangular area to the sliver, thereby Make the sliver generate additional twist to achieve the effect of airflow concentration, because the energy consumption of the mechanical force is far less than the energy consumption of the airflow force, so it fundamentally solves the problem of high energy consumption that restricts the development of compact spinning, and provides a A New Mechanical Compact Spinning Method
