Abstract

The invention discloses a textile raw material staining method with stable staining. The textile raw material staining method comprises the following steps: S1: in a staining jar, adding stain and water, evenly stirring, raising temperature to 55-60 DEG C through a 3-4 DEG C temperature raising rate, keeping for 1.5h, and adding carbonic acid to regulate the pH (Potential of Hydrogen) of stainingliquid to 5; S2: dipping texture raw materials in the staining jar for 1.5-3.5h, then, raising the temperature at the speed of 2-3 DEG C / min, raising the temperature to 93-96 DEG C, and keeping for 2.5h, wherein the bath ratio of the texture raw material is 1:18; S3: drying; S4: rinsing; S5: drying. The stain is prepared from the following raw materials in parts by weight: 8-10 parts of 4-[(1,3-Dihydro-1,3-dioxo-5-isobenzofuranyl)oxy]-1,3-isobenzofurandione, 2-5 parts of polypropylene glycol, 18-20 parts of mica powder, 2-5 parts of zinc stearate, 4-7 parts of propyl acetate, 9-12 parts of iron oxide red, 7-10 parts of ethyl triethoxysilane, 6-12 parts of sodium hydroxide, 4-7 parts of sodium carbonate, 3-5 parts of ethyl alcohol, 40-45 parts of water and 5-8 parts of polyvinylpyrrolidone.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a method for dyeing textile raw materials with stable dyeing. Background technique [0002] With the improvement of people's living standards, people's requirements for textiles are getting higher and higher. A large number of fabrics blended by fibers of different properties have emerged on the market, so that the fabrics have the characteristics of different fibers simultaneously. Commonly used are polyester-cotton blended fabrics, which are woven by blending polyester and cotton. On the one hand, polyester fibers have the characteristics of high strength and good wrinkle resistance, and at the same time, cotton has the advantages of good hygroscopicity and comfortable wearing. However, when dealing with the dyeing of this type of fabric, the printing and dyeing effect of the fabric is not ideal due to the limitation of the process, which affects the fullness and color fastn...
