Problems solved by technology

[0006] In order to solve the problem of large desizing wastewater discharge pollution (all desizing wastewater) and high energy and water consumption in the traditional sizing and dyeing process of denim blended warp yarns, although there is no desizing wastewater discharge by using desizing-free sizing and dyeing technology And can reduce water consumption and energy consumption, but the drapability or softness of the denim that it is woven is insufficient and avoids problems such as high cost of desizing size, the present invention provides a kind of drapability of denim or good softness (drape Coefficient less than 32%), less desizing wastewater discharge, low cost denim blended warp yarn sizing process based on partial desizing

Abstract

The invention discloses a dye sizing process with partial desizing for cowboy blending warp yarn. According to the process, a color paste-containing self-crosslinking desizing-free polyacrylate emulsion sizing agent is mixed with water and stirred uniformly, a preliminary dye sizing treatment is carried out for the cowboy blending warp yarn by a stock trough dip dyeing sizing and roller pad dyeing sizing process, after dye sizing, the cowboy blending warp yarn is dried by a dying cylinder and is carried out by a crosslinking and solidification treatment, a color paste-free self-crosslinking polyacrylate emulsion sizing agent is used for further sizing, coating and dye fixing treatment of the cowboy blending warp yarn by a 'one dipping one rolling' process, and a sale modified starch sizing agent is used for sizing according to the traditional process. The cowboy blending warp yarn treated by two steps of dye sizing and sizing is woven with a filling yarn, and after weaving, only a sizing membrane formed by the sale modified starch sizing agent is carried out by a desizing treatment according to the traditional process; the process provided by the invention can reduce the desizing waste water discharge; compared with the desizing-free dye sizing process, the drapability of the denim produced by the invention is increased by 30% or more, and the sizing agent cost and the energy consumption are reduced.

Description

technical field [0001] The invention relates to a denim blended warp yarn sizing process, in particular to a denim blended warp yarn monochromatic paint sizing process based on partial desizing and a paint indigo stereochromatic sizing process; it belongs to the technical field of textile printing and dyeing. Background technique [0002] The textile printing and dyeing process of denim usually includes warp yarn dyeing, sizing, weaving, desizing, finishing and other processes. The warp yarn is mainly dyed with traditional indigo dyes, and sometimes some sulfur dyes or other vat dyes are also used. With the development of textile printing and dyeing technology and the change of people's consumption concept, on the one hand, more and more blended fibers (such as polyester / cotton, cotton / viscose, etc.) and new fibers appear, making the raw materials of denim more and more widely; On the other hand, the color of denim is more colorful, and various color-coated denim such as blu...
