A kind of textile yarn dyeing process

Abstract

The invention relates to a textile yarn dyeing process. The textile yarn dyeing process uses a textile yarn drying processing device; the textile yarn drying processing device comprises a dyeing mechanism, a drying mechanism and a winding mechanism; the drying mechanism is arranged at the right side of the dyeing mechanism; the winding mechanism is arranged at the right side of the drying mechanism; and the lower end of the drying mechanism, the lower end of the drying mechanism and the lower end of the winding mechanism are all installed on the existing working ground. According to the textile yarn dyeing process provided by the invention, the design concept of a dyeing-drying-winding integrated structure is adopted to perform yarn dyeing treatment, wherein a rotatable structure is arranged in the dyeing mechanism and the drying mechanism to improve the yarn dyeing uniformity degree and the uniform drying degree of dyed yarns, and meanwhile, the dyed yarns and initial colorless yarnscan be separately wound, so that the molding quality of a dyed yarn bobbin is improved.

Description

technical field [0001] The invention relates to the technical field of yarn textile production, in particular to a textile yarn dyeing process. Background technique [0002] Yarn is a kind of textile, which is processed into products of a certain fineness with various textile fibers. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into staple fiber yarn, continuous filament, etc. There are many varieties and different properties. It can be pure spinning made of natural fibers or various chemical short fibers, or a blended yarn made of several fibers, or it can be directly sprayed from chemical fibers. The processed filament yarn can usually be classified according to the raw materials used in the yarn, the thickness of the yarn, the spinning method, the spinning system, the structure of the yarn and the use of the yarn, etc. The yarn can be divided according to the process, which is divided into Pure spinning, blended yarn, ne...

AI Technical Summary

Problems solved by technology

[0003] 1. When immersing bundled and other overall forms of yarn in the dyeing solution in a static state for dyeing treatment, the dyeing solution that has been standing for a long time is prone to delamination, resulting in uneven color and mottled yarns. The phenomenon, and the degree of dyeing inside and outside the yarn bundle is different, which will easily lead to a low degree of uniform dyeing of the overall yarn. At the same time, the dyeing and drying process of the yarn is not continuous, so that the yarn cannot be dried in time, and the yarn Lines are prone to dark and light color separation areas;

[0004] 2. When monofilaments are dyed side by side, dried, and rolled into shape, the initial winding section of the yarn is not dyed, and this colorless section forms a mixed winding state with the subsequent dyed yarn, thereby reducing the dyed yarn formed. At the same time, during the yarn drying process, the yarn tends to be in a loose state, which causes the yarn to contact the drying structure, and then fuses or scorch marks appear on the contact part of the yarn, and the wrinkles on the loose yarn are easy to make the yarn The drying degree of the yarn is different, and the yarn is prone to have different shades in the end
