Abstract

The invention discloses reactive dye printing paste as well as a preparation method and an application thereof. The reactive dye printing paste is prepared from the following materials: sepiolite, kerosene, an emulsifying agent, urea, a reserve salt S, soda ash and water. The invention further provides an application of the reactive dye printing paste to printing and dyeing of towels and velvet fabrics. A preparation process of the reactive dye printing paste comprises the following steps: preparing the reactive dye printing paste, preparing color paste, printing a textile, drying, steaming, washing with water, soaping and drying; the reactive dye printing paste is formed by compounding the sepiolite and the emulsified kerosene; the sepiolite and the emulsified kerosene have good compatibility; and the formed color paste has good printing-through property and good stability of resistance to water and electrolyte and is low in cost, and the printing is ecological and environmentally friendly.

Description

technical field [0001] The application belongs to the fields of textile and printing and dyeing, and in particular relates to a reactive dye printing paste and its preparation method and application. Background technique [0002] With the overall improvement of the world's economic level today, people's demand for clothing, textiles, etc. is becoming more and more individualized and diversified. Compared with dyed fabrics, printed fabrics are full of changes in color and pattern, making them have a strong artistic effect and aesthetic feeling, which greatly meets people's humanized needs. As far as the current printing technology is concerned, whether it is roller printing, screen printing or inkjet printing, printing paste is involved. The printing effect of paste printing is closely related to the printed fabric and printing method, as well as the printing paste composed of paste, dyes and auxiliaries. Since the paste controls the rheology of the printing paste and the p...
