Technical Field

The invention relates to the field of accelerating agents, in particular to the field of low-temperature accelerating agents for wool.

Background

The wool is used as a pure natural protein fiber, the hand feeling is full, the hygroscopicity, the elasticity, the air permeability, the heat retention and the comfort are excellent, the wool has a unique garment effect and is deeply favored by people, and the wool is not easy to be wetted in the dyeing process and is difficult to color by dye because the surface of the wool is covered by a layer of scales with directional friction effect and has hydrophobic property.

In the general wool dyeing process, water is boiled at the temperature of about 100 ℃, a large amount of energy and cost are consumed, the dyeing time is long, the wool is seriously damaged due to long-time high temperature, the problems of strength reduction, weight loss embrittlement and the like of wool fibers are caused, the great problem is brought to the subsequent spinning processing, and the rough hand feeling of the wool is easily caused.
