Description

Cashmere low-temperature dyeing method

Technical field

The present invention relates to cashmere low-temperature dyeing method.

Background technology

In prior art, the common process of cashmere dyeing is that the dyestuff adopting contains hairiness low temperature dyeing assistant 1.8-2%, bleeding agent FFA0.5%, levelling agent 1%, reactive dye for wool 0.0001-7%, acetic acid 0.8-3.5%, method of operating: intensification 1 per minute is spent, be raised to 80-90 degree (light color 80 degree, dark 90 degree); Be incubated 30-60 minute (light color 30 minutes, dark 60 minutes).

Summary of the invention

The object of this invention is to provide a kind of cashmere low-temperature dyeing method, reduced the use amount of batching, reduce costs, improve spinnability, improve weaved rate.

Technical scheme of the present invention is as follows:

Cashmere low-temperature dyeing method, includes following operating procedure:

A. prepare coloring agent, coloring agent is made up of the component of following mass percent: hair is used low temperature dyeing assistant 1.8-2%, reactive dye for wool 0.0001-7%, and acetic acid 0.8-4%, surplus is water;

B. dye the stage, intensification 1 per minute is spent, and is raised to 80-90 degree, and wherein light cashmere is 80 degree, and dark cashmere is 90 degree; Insulation 30-60 minute, wherein light color is 30 minutes, dark color is 60 minutes.

Described hair is the triumphant chemical industry hair of Tianjin moral low temperature dyeing auxiliaries SN with low temperature dyeing assistant.

The present invention has reduced the use amount that bleeding agent FFA, levelling agent are prepared burden, and reduces costs, and improves spinnability, improves weaved rate.
