Problems solved by technology

However, although the surface of wool after plasma treatment presents a nano-scale concave-convex structure, and the hydrophilicity has been improved to a certain extent, when it comes to dyeing with reactive dyes, the dyeing rate is still not ideal under low temperature conditions, and the microstructure of wool fibers is not full. Treated wool feels poor

Abstract

The invention discloses a plasma pretreatment and dyeing method of wool fabric. The method comprises steps including preparation of a dye mixed solution, low-temperature plasma pretreatment of fabric, dyeing, after-treatment and the like. Active polar groups can be grafted on surfaces of wool fibers through plasma treatment in different atmospheres in a plasma treatment cavity, condensation or crosslinking reaction sites of dyes and the wool fibers can be increased, and the dye uptake can be increased; rare earth ions react with hydroxyl groups, carboxyl groups, sulfonic acid groups and the like on dye molecules to produce macromolecular complexes, the compatibility of the different dyes is improved, the dyed wool fabric has the uniform color, the rare earth ions can also have a coordination reaction with groups, which determine wool whiteness, of lysine residual bonds and the like, which are exposed after ionic liquid treatment, in the wool fibers, and less yellowing of the wool color before and after dyeing is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a plasma pretreatment dyeing method for wool fabrics. Background technique [0002] The traditional high-temperature dyeing of wool not only consumes a lot of energy, but also makes the wool suffer from chemical reagents and heat at high temperature, causing the wool to turn yellow, greatly affecting the fiber appearance and physical and mechanical properties, and destroying the excellent natural quality of wool. At present, there are chlorine salt oxidation pretreatment methods, formic acid pretreatment methods, and biological enzyme pretreatment methods for wool low-temperature dyeing methods at home and abroad. In the chlorine salt oxidation pretreatment method, no matter it is sodium dichloroisocyanurate (DCCA) or sodium hypochlorite, AOX will be produced during use, which will cause certain pollution to the environment; in the formic acid pretreatment method, the amount of f...
