Abstract

The invention provides printing paste adopting an ionic liquid. The printing paste comprises components in percentage as follows: 0.1%-10% of cationic reactive dyes, 1%-4% of sodium bicarbonate, 0-1% of reserve salts and the balance of 1-butyl-3-methylimidazolium hexafluorophate. 1-butyl-3-methylimidazolium hexafluorophate in the printing paste is taken as the ionic liquid and can be used as a thickener, a solvent, a penetrating agent or a washing agent. Compared with conventional reactive dye printing paste adopting sodium alginate, the printing paste adopting the ionic liquid has the benefits as follows: (1), original paste preparation is not required, and a preparation method is simple; (2), soap washing is not required after printing treatment, time and labor are saved, and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, in particular to an ionic liquid printing paste. Background technique [0002] Textile printing is a method of printing dyes or paints on fabrics to form patterns in a certain way. For dye printing and dyeing, it has the same principle of action and the same dyeing materials, but the transfer medium of printing and dyeing is different, and it belongs to partial dyeing. . [0003] The development process of textile printing technology is ancient and long. In the first millennium of the human era, our ancestors made outstanding contributions to the development of fabric printing techniques. The birthplaces of various printing techniques that are common today, such as direct printing, resist printing, pad dyeing, and batik in China. Until the Scots invented the hardener in the 17th century, machine printing played a very important role in the historical transformation of fabric printi...
