Problems solved by technology

[0002] In the production process of the textile industry, in the desizing, refining, bleaching, dyeing, finishing and other process steps of the weaving of fabrics in the textile printing and dyeing process, some fabrics can be dyed with brighter colors through the action of dyes. Well, it will affect the fastness, and the phenomenon of fading and color sticking is more serious, which not only makes the fabric itself look old, but also the pigment will fall from the wet fiber that has been dyed, staining white or dyeing other colors On the fiber, fabrics of different colors will stain and match each other during washing.

Embodiment Construction

[0014] 1 Accurately weighed by weight: 20 parts of acrylate; 5 parts of epichlorohydrin; 1.5 parts of organosiloxane; 1.5 parts of 2.2-azobis (2-methylpropoxy acid); 5 parts of cyanamide; 100 parts of deionized water, set aside.

[0015] 2. Preparation method

[0016] (1) Add acrylate to the reaction vessel, heat up to 50-60°C, add epichlorohydrin, and react for 2-3 hours under stirring;

[0017] (2) After cooling, add organosiloxane under ice-water bath, react for 1-3 hours,

[0018] (3) Add distilled water, heat up to 50-60°C, add 2.2-azobis(2-methylpropoxy acid), and react for 3-5 hours;

[0019] (4) Add polypyrrolidone and dicyandiamide, and react for 1 to 3 hours under stirring conditions;

[0020] (5) After cooling, the finished product is obtained

[0021] When used, it is 1.2% to 1.8% of the weight of the fabric, the bath ratio is 1:20, and the temperature is 40°C to 60°C.

Abstract

The invention relates to a textile printing and dyeing pigment color fixing agent and a preparation method thereof. The textile printing and dyeing pigment color fixing agent mainly comprises acrylic ester, epichlorohydrin, organic siloxane, 2.2-azodi(2-methopropoxy acid)polyvinyl polypyrrolidone, dicyandiamide and deionized. The textile printing and dyeing pigment color fixing agent has a good color fixing effect on textiles which are dyed by pigments and small influences on textile colored lights, free formaldehyde is not generated in a synthetic process, and the textile printing and dyeing pigment color fixing agent belongs to an environment-friendly color fixing agent.

Description

technical field [0001] The invention relates to a color-fixing agent for textile printing and dyeing pigments and a preparation method thereof, belonging to the technical field of textile dyeing auxiliaries. Background technique [0002] In the production process of the textile industry, in the desizing, refining, bleaching, dyeing, finishing and other process steps of the weaving of fabrics in the textile printing and dyeing process, some fabrics can be dyed with brighter colors through the action of dyes. Well, it will affect the fastness, and the phenomenon of fading and color sticking is more serious, which not only makes the fabric itself look old, but also the pigment will fall from the wet fiber that has been dyed, staining white or dyeing other colors On the fiber, fabrics of different colors will stain and match each other during washing. Therefore, in the dyeing process, it is necessary to add a color-fixing agent to enhance the fastness of the pigment. [0003] ...
