Problems solved by technology

However, due to the poor air permeability of pigment printing, easy to absorb dust, and poor friction and scrubbing fastness, the light fastness, scrubbing fastness, color brightness and surface uniformity of disperse reactive dye printing are not suitable for frequent outdoor operations, field training, etc. Highly demanding military clothing fabrics and anti-counterfeiting devices are still not up to the ideal level
Therefore, T / C clothing fabric disperse / vat dye printing has become the only ideal choice for printing and dyeing enterprises at home and abroad. It is famous for its bright colors, unique color fastness, and high-grade products. It is widely used especially in European and American markets. Due to the high cost, complicated process and special equipment of this kind of printing, it is not widely used in our country.

Abstract

The invention discloses a dispersing / reducing printing process for a polyester / cotton blended fabric, which belongs to the technical field of printing of polyester / cotton blended fabrics. The process comprises the following successive steps: reception of a sample from a customer; color separation; draft drawing; preparation of a net; inspection of a gray fabric; sewing; singeing; desizing and scouring and bleaching; mercerizing; performing; printing; primary drying; baking; rolling of reduction liquid; rapid vat ageing; primary washing; oxidation; ventilation; oxidation; secondary washing; soaping; ternary washing; secondary drying; shaping; inspection; and inspection of a finished product. The dispersing / reducing printing process for the polyester / cotton blended fabric provided by the invention has the advantages of a good printing effect, low cost and simple process.

Description

technical field [0001] The invention discloses a polyester / cotton blended fabric dispersion / reduction printing process, belonging to the technical field of polyester / cotton blended fabric printing. Background technique [0002] Due to the different physical and chemical properties of polyester and cotton fibers, it is very difficult for the same dye to be dyed on the two fibers at the same time. For products with excellent fastness, it is difficult to achieve the desired effect by using conventional polyester printing, dispersion / reactive co-sizing printing, especially in the printing of high-end T / C camouflage fabrics. In recent years, many experts and scholars at home and abroad have devoted themselves to improving the hand feel and color fastness of coatings, and through the research on the structure of disperse and reactive dyes, they have produced a special dispersing active dye for T / C and T / R blended fabrics. dyes, and are recognized in practical production. However...
