Artificial cotton active printing technology, and artificial cotton textile fabric

Abstract

The invention discloses an artificial cotton active printing technology. The artificial cotton active printing technology comprises steps of pretreatment; printing; steaming; and water washing. 1000 parts of a color past adopted in the step of printing is composed of, by weight, 20 to 50 parts of a blended black active dye, 300 to 500 parts of a sodium alginate original paste, 100 to 200 parts ofurea, 10 to 30 parts of reserve salt S, 10 to 40 parts of sodium carbonate, and the balance water. The invention also discloses the artificial cotton textile fabric prepared through the artificial cotton active printing technology. According to the artificial cotton active printing technology, the blending synergistic principles of the blended black active dye are adopted, so that excellent substantivity, color fixing rate, colour fastness to wet rubbing, and colour fastness to perspiration are achieved, and the artificial cotton active printing technology is especially suitable for artificialcotton textile fabric.

Description

technical field [0001] This application relates to the field of textile printing. Specifically, the present application relates to a rayon reactive printing process. The present application also relates to the rayon textile fabric made by the rayon reactive printing process. Background technique [0002] Rayon fabric has the advantages of soft texture, smoothness, strong air permeability and good comfort, and is an ideal summer fabric. At present, rayon textiles in the market are dominated by printed products, and most of them are printed with reactive dyes. The quality of printed products mainly depends on the structure and composition of reactive dyes used in printing pastes. The more common reactive dyes are divided into black, red, orange and yellow. Among them, the amount of black reactive dyes accounts for almost half. [0003] In order to obtain black, reactive black KN-B is usually used as a monomeric reactive dye. The price of this dye is cheap, and its fastnes...

AI Technical Summary

Problems solved by technology

However, the reactive black KN-B has low absorption in the orange and yellow wavelength regions, showing a navy blue color, and the blackness is not enough

In addition, the dye also has defects such as insufficient directness, low color fixation rate, unsatisfactory color fastness to wet rubbing and perspiration resistance. Therefore, in recent years, for high blackness, high color fixation rate and high color fastness More and more attention has been paid to the research and development of the new type of rayon reactive printing reactive technology

[0004] In order to improve the blackness, in the prior art, the principle that orange is the complementary color of navy blue is mainly used. Although the dye properties of reactive black KN-B are improved to a certain extent by blending orange components and / or yellow components, there are still Insufficient directness, low color fixation rate, color fastness to wet rubbing and color fastness to perspiration
