Abstract

The invention discloses reactive disperse slurry and a printing method thereof. The reactive disperse slurry is prepared from the following raw materials in percentage by weight: 0.1%-6% of a reactive dye, 0.1%-6% of a disperse dye, 1%-2% of baking soda, 0-5% of urea, 0.8%-1.2% of reserve salt and the balance of synthetic paste. According to the reactive disperse slurry and the printing method thereof disclosed by the invention, the dyed product is even and full, white in bottom and bright white, and can show good dry and wet fastness; and the process is stable and feasible, and can be applied to mechanical batch production.

Description

technical field [0001] The invention relates to an active dispersion paste and a printing method thereof. Background technique [0002] In the current textile industry, the proportion of polyester-cotton blended products can reach 30%-40% of all textiles. Polyester-cotton knitted fabric has the advantages of moisture absorption, breathability, good dimensional stability, etc., and has good clothing performance, and is widely used in sportswear, casual clothing, etc. However, polyester-cotton blended fabrics face a large number of technical problems in the process of printing and dyeing, due to the limitations of various conditions. Poly-cotton blended knitted fabrics are limited to pigment printing and hand printing. [0003] The main difficulty of reactive disperse printing is that disperse dyes contaminate cotton fibers more seriously, and reactive dyes also contaminate polyester to some extent. This situation is very easy to occur in steamed water washing. Once c...
