Problems solved by technology

However, there are also many technical problems in this process, mainly in the following aspects: (1) Due to the need for reactive dyes to fix the color, the color paste contains alkali agents, but most of the disperse dyes are sensitive to alkalis, and they are easy to change color and fade when encountering alkalis , reduce the color fixation rate, and even destroy the dye structure; (2) Since disperse dyes need to be fixed under high-temperature baking conditions, polyester-cotton blended fabrics (mainly cotton fibers) are prone to yellowing under high temperature and the presence of alkali agents , at the same time, there are two kinds of dyes that stain different fibers respectively, resulting in the disadvantages of reduced color brilliance and white ground.

Abstract

The invention discloses an active and dispersive one-paste printing process of a cotton-polyester blended knitted fabric. The process comprises the following steps: designing a printing pattern; preparing cotton-polyester knitted plain cloth; preparing a stock thickener, colored paste and alkaline slurry; printing; roasting; overprinting the alkaline slurry; steaming; washing; and drying. The active and dispersive one-paste printing process of the cotton-polyester blended knitted fabric disclosed by the invention lays emphasis on a process flow of coloring a disperse dye and an active dye in different pH value ranges by applying existing equipment of a printing and dyeing mill according to the fixation condition of the disperse dye and the active dye when dispersive/active one-paste printing is carried out on the cotton-polyester blended knitted fabric, so that the technical problem that active and dispersive one-paste printing of the cotton-polyester blended knitted fabric cannot be widely produced in batch is solved.

Description

technical field [0001] The invention relates to a printing process for polyester-cotton blended knitted fabrics, in particular to an active and dispersed same-sizing printing process for polyester-cotton blended knitted fabrics. Background technique [0002] Polyester-cotton blended knitted fabrics are bulky and comfortable to wear, soft to the touch, moisture-absorbing, breathable, and non-deformable for leisure, and are favored by consumers. The printing of polyester-cotton blended knitted fabrics has different coloring properties due to the different physical structures and chemical properties of polyester fibers and cotton fibers. At present, the printing of polyester-cotton blended knitted fabrics at home and abroad is mostly limited by equipment, and about 70-90% of them use pigment printing technology. Although the process of pigment printing is simple, when printing deep and thick colors and large-area patterns, it generally feels hard after printing, has poor rubbi...
