Novel barrel yarn tension control device for dyeing

Abstract

The invention relates to a spinning dyeing process device, in particular to improvement of a tension control device for dip dyeing barrel yarn during spooling. The novel barrel yarn tension control device for dyeing comprises yarn guiding grooves. The bottom of each yarn guiding groove is bent and raised upwards along the length direction of the yarn guiding grove, the direction that the yarn guiding groove is raised upwards is the direction that the bottom of the yarn guiding groove points to a notch of the yarn guiding groove, and air driving devices are mounted around the yarn guiding grooves. By the arrangement, distribution of strain inside the barrel yarn during the spooling can be changed, so that fluidity of dye liquor flowing from the inside of to-be-dyed barrel yarn to the outside can be enhanced, outer yarn can be prevented from slipping, and dyeing quality and efficiency can be improved.

Description

Technical field: [0001] The invention relates to a spinning and dyeing process device, in particular to the improvement of a tension control device in the winding process of a dip-dyeing bobbin yarn. Background technique: [0002] Exhaust dyeing is the only way to dye the package yarn. The yarns to be dyed that have been wound on the dyeing tube are hung one by one on the suspender of the dyeing vat and immersed in the dyeing solution. On the one hand, the dyeing solution flows from the outer yarn to the inner layer. The yarn penetrates to make the package dye continuously. On the other hand, the dye solution flows from the inner layer yarn to the outer layer yarn through the through hole on the inner wall of the dyeing tube to continuously dye the package yarn. play a leading role in the process. There are following two defects in this dyeing process: 1. The amount of yarn in each package is large, which is 20 to 50 times the weight of each skein in the dyeing of the skein...

AI Technical Summary

Problems solved by technology

There are following two defects in this dyeing process: 1. The amount of yarn in each package is large, which is 20 to 50 times the weight of each skein in the dyeing of the skein, so the thickness of the middle part of the package is large; 2. . Due to the constant tension during the winding process, the bobbin tends to become tighter and tighter from the outer layer to the inner layer. The closer to the inner layer, the stronger the extrusion force and the greater the density.

[0003] The main reason for the above phenomenon is that there are currently four types of tension control devices for bobbins in the winding process in the industry at home and abroad: washer type, spring type, comb type and electromagnetic type. The first two are always in the winding process. Add a constant tension, the latter two are when the tension of the yarn changes instantaneously during the winding process, immediately add an additional compensation force so that the tension during the winding process is always constant, and their common result is that the winding process The tension is constant. During the winding process, the bobbin tends to become tighter and tighter from the inner layer to the outer layer. The closer to the inner layer of the yarn, the stronger the extrusion force is, which is not conducive to the dyeing liquid from the inner layer yarn to the outer layer. yarn flow

[0004] At present, the device that can improve the internal tension distribution of the package yarn during the winding process, so that it can more effectively enhance the fluidity of the dye liquor from the inner layer yarn to the outer layer yarn during the package dyeing process has not yet been seen.
