Problems solved by technology

Under acidic conditions, reactive dyes basically do not color cotton fibers. Reactive dyes must be fixed under alkaline conditions, but alkaline conditions make the dyeing rate of acid dyes on nylon very low. Mutual staining of cotton and nylon not only affects the color fastness of printing, but also stains the white ground of printing, affecting product quality

Abstract

The invention discloses a polyamide-cotton mixed fabric catalyzing and printing technology in the same sizing agent. The technological process comprises the following steps in sequence: printing, drying, steaming, washing with hot water, soaping, washing with water, and drying. The technology of utilizing an activated dye / a neutral dye to be combined with dicyandiamide to catalyze and fix the color can obviously improve the printing color depth, reduces the dosage of an alkaline agent, realizes dyeing of the activated dye to the cotton in the fabric under the alkalescent condition, meanwhile cannot influence the dyeing of the neutral dye to polyamide, so as to achieve a good printing effect; the fastness to wet rubbing of the printed fabric can be up to level 4.

Description

[0001] technical field [0002] The invention belongs to a printing process, and in particular relates to a cotton-nylon interwoven fabric same-slurry catalytic printing process. [0003] Background technique [0004] Cotton and nylon blended or interwoven products not only have high wear resistance and strength, but also have the advantages of both fibers at the same time, and have excellent wearability. The dyed products have been popular in the market for several years. However, its printing products have been difficult to meet the needs of the market due to technical reasons. The production of cotton nylon printed fabrics has certain difficulties. Usually, acid dyes are used to dye nylon, and reactive dyes are used to dye cotton. Under acidic conditions, reactive dyes basically do not color cotton fibers. Reactive dyes must be fixed under alkaline conditions, but alkaline conditions make the dyeing rate of acid dyes on nylon very low. Mutual staining of cotton and nyl...
