The seoiolite printing gum is prepared from 1-90 parts by weight of sepiolite and 1-99 parts by weight of sodium alginate, totaling 100 parts by weight. The invention further discloses sepiolite printing paste. The sepiolite printing paste is prepared from the seoiolite printing gum, reactive brilliant blue KN-R, urea, sodium carbonate, a reserve salt S and water. The invention further discloses preparation methods and applications of the seoiolite printing gum and the sepiolite printing paste. The technology has a remarkable cost advantage and high product performance, and has contribution to enterprise environment protection.

Description

technical field [0001] The application belongs to the field of textile dyes, and in particular relates to a sepiolite printing paste, a sepiolite printing color paste and a preparation method and application thereof. Background technique [0002] The conventional processing steps of textiles include pretreatment, dyeing, printing and finishing. Fabric printing is the process of applying dyes or paints to form patterns on fabrics. Whether it is conventional screen printing or advanced digital printing, printing paste must be applied in the printing process to make the dye (or paint) adhere to the surface of the fabric, and then through deep processing to make the dye and the fabric occur. A better fastness is obtained by chemical bonding. Therefore, printing pastes are indispensable in the textile printing process. However, after the dye is fully combined with the fabric, the printing paste needs to be completely washed off (also known as depaste), otherwise it will affect...
