Production process of printing and dyeing product

Abstract

The invention belongs to the technical field of dyeing and printing products, discloses a production process of a printing and dyeing product, and aims to solve the problems of poor color matching, single cloth cover effect and the like of existing dyeing and printing cloth and increase hand feeling selection of the dyeing and printing cloth. The method comprises the following steps of S1, spinning; S2, yarn dyeing; S3, warping; S4, sizing; S5, drafting; S6, forming grey cloth; S7, carrying out subsequent processing; and S8, forming a finished product. The step of yarn dyeing is introduced, and only terylene is dyed in the step of yarn dyeing, so that, compared with similar cotton and terylene blended elastic products, the mode can keep the activity of spandex under the condition of achieving the same cloth cover effect, and better elastic elongation and wearing comfort are achieved. On the whole, the production process disclosed by the invention can greatly enrich the collocation of products, and meanwhile, the risk of secondary pollution during production in a grey cloth factory in a traditional process can be well eliminated, so that the overall operability is improved.

Description

Technical field [0001] The invention belongs to the technical field of dyeing and printing products, and specifically relates to a printing and dyeing product production process. Background technique [0002] At present, most of the garments and pants are made of cotton or cotton-polyester blended / interwoven or blended with other raw materials; for the entire production process of dyeing and printing products, most enterprises in the industry currently only have separate printing and dyeing plants, Grey fabric factories or yarn-dyed fabric factories; therefore, the corresponding manufacturers have only relevant product production experience, and cannot integrate the entire production process of dyeing and printing fabric products to produce differentiated products. In addition, in the production process of dyeing and printing fabric products, if the traditional process is to achieve close results, the gray fabric factory is likely to pollute various production equipment when prod...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the raw materials used in underwear are cotton or cotton-polyester blended / interwoven or blended with other raw materials; for the entire production process of dyed and printed products, most enterprises in the industry currently only have separate printing and dyeing factories, Gray fabric factories or yarn-dyed fabric factories; therefore, the corresponding manufacturers only have the production experience of related products, and cannot well integrate the entire production process of dyed and printed fabric products to produce differentiated products

In addition, in the production process of dyed and printed fabric products, if the traditional process is to achieve a similar effect, the gray fabric factory is likely to pollute various production equipment when producing gray fabrics; Washing and re-dyeing cotton and other steps, such that dyeing polyester at high temperature will increase energy consumption and damage the activity of spandex; and in the re-soaping process, in order to ensure the color fastness of washing water is qualified, this process will increase sewage discharge; in addition, printing and dyeing Adding dyeing links in the factory will also increase fabric production loss and reduce aging

Therefore, the existing production process of dyeing and printing products often causes secondary pollution of other varieties and the consumption and waste of resources. At the same time, dyeing and printing fabric products have the problems of low yield rate and poor quality stability of finished products, so the economic benefits of manufacturers are greatly reduced. less than good protection
