Two-for-one twisting false twisting yarn channel by two-side rounding type coaxial double-overfeeding one-step method

Abstract

The invention relates to a two-for-one twisting false twisting yarn channel by a two-side rounding type coaxial double-overfeeding one-step method; left yarns orderly pass through a left two-for-one twisting spindle and a second left yarn idler wheel to round to a first yarn channel of a left double-overfeeding roller, and enter into a hot box; after being discharged from the hot box, the left yarns are sent to a left false twister through a first left yarn idler wheel, pass through a third left yarn idler wheel to round to a second yarn channel of the left double-overfeeding roller, and are sent to a left winding component by a left moving spinning nozzle; right yarns orderly pass through a right two-for-one twisting spindle and a second right yarn idler wheel to round to a first yarn channel of a right double-overfeeding roller, and enter into the hot box; and after being discharged from the hot box, the right yarns are sent to a right false twister through a first right yarn idler wheel, pass through a third right yarn idler wheel to round to a second yarn channel of the right double-overfeeding roller, and are sent to a right winding component by the left moving spinning nozzle. The two-for-one twisting false twisting yarn channel is high in speed and low in cost without rigid yarns and wool yarns.

Description

technical field [0001] The invention relates to a double-side winding type coaxial double overfeeding one-step double-twisting and false-twisting thread path, which belongs to the technical field of textile machinery. Background technique [0002] The one-step two-for-one twisting and false twisting machine completes the three processing functions of twisting, setting and false twisting on one machine. After processing through three processes, the silk thread becomes real twisted false twisted silk. The silk thread has the characteristics of good elastic retraction, good bulkiness and soft hand feeling, just like the characteristics of twisted real silk, commonly known as "imitation silk". [0003] At present, there are two types of yarn paths used in one-step two-for-one twisting and false twisting machines on the market. The first is double-sided straight-running yarn paths such as figure 1 , the second is a double-sided winding silk channel such as figure 2 . The main...

AI Technical Summary

Problems solved by technology

The main features of the double-sided straight-running silk path are: the silk path is concise, and the finished silk is relatively "thin and thin", which is convenient for mechanical aided design and actual operation; Appears "full" type, which is not conducive to mechanical aided design and actual operation
