A bobbin and a dyeing process applied to the bobbin

Abstract

The invention discloses a yarn reel and a dyeing process applied to the yarn reel. The yarn reel includes a cylinder body for winding cloth to be dyed, and a first side plate and a second side plate respectively arranged at two ends of the cylinder body. plate, the cylinder is composed of a plurality of cylinder members, the cylinder members are sequentially connected end to end along the circumferential direction of the cylinder to form the cylinder, and, along the circumference of the cylinder, the distance between adjacent cylinder components can be Adjustment; an inner positioning sleeve is arranged in the cylinder body, and the cylinder body and the inner positioning sleeve are coaxially arranged, and a return spring for adjusting the distance between the cylinder body and the inner positioning sleeve is arranged between the cylinder body and the inner positioning sleeve. It can be seen that the bobbin can shrink or expand within a certain range in the radial direction. When the cloth to be dyed is wound on the bobbin of the bobbin, the bobbin of the bobbin maintains the maximum diameter. When the cloth shrinks during the dyeing process , the cylinder can automatically shrink radially inward. Compared with the prior art, the present invention saves the process cost more and reduces the operation process.

Description

technical field [0001] The invention relates to the field of textile processing and manufacturing, in particular to a yarn reel and a dyeing process applied to the yarn reel. Background technique [0002] Dyeing technology refers to a technology that uses dyes to dye and process dyed objects. In the process of dyeing textiles, the cloth to be dyed is generally wound on a bobbin so as to facilitate dyeing. For example, the yarn drum used for dyeing zipper tape is a metal circular cylinder made of stainless steel. The cylinder body is rigidly connected (such as welding) to the side plates located at both ends of the yarn drum. The zipper tape is evenly wound by a tape winding machine. On the cylinder body of the dyed yarn reel, the yarn reel wound with the zipper cloth tape is placed in a dyeing vat for dyeing during dyeing. [0003] In the dyeing process of the actual production process, since the fabric to be dyed needs to be subjected to high temperature and high pressure...

AI Technical Summary

Problems solved by technology

The purpose is to establish an elastic buffer zone between the zipper tape and the outer circle of the yarn tube to solve the problem of affecting the dyeing quality due to the shrinkage of the tape

But above-mentioned solution not only has increased manufacturing cost, and has only a buffer distance of a few tenths of a millimeter after wrapping several layers of non-woven fabrics or metal stainless steel wire mesh on the circumference of the yarn bobbin, which cannot fully meet the internal requirements of the zipper tape during dyeing. shrink requirements
