A kind of anti-perspiration firm enhancer and its preparation method and application

Abstract

The invention provides a perspiration-resistant fastness improver. The perspiration-resistant fastness improver is mainly prepared from the following raw materials in parts: 10 to 200 parts of urea substance, 10 to 100 parts of organic solvent, 1 to 10 parts of film-forming agent and 20 to 200 parts of water. The preparation method comprises the following steps of (A), mixing and stirring the urea substance and the water until the urea substance is dissolved, wherein the temperature is controlled to be 25 to 30 DEG C; (B), after reducing the temperature to 15 to 20 DEG C, adding the film-forming agent and the organic solvent, and continuously stirring for 30 to 60 minutes to obtain the perspiration-resistant fastness improver. The perspiration-resistant fastness improver provided by the invention can be well applied to a fur dyeing post-processing process, is good in perspiration resistance and high in stability, has very strong pertinence, remedies the phenomenon that perspiration fastness of fur is generally low in a fur dyeing field, and has important significance in further widening fur market range and increasing sales.

Description

technical field [0001] The invention relates to the field of animal fur processing, in particular to a perspiration-resistant firmness improving agent and its preparation method and application. Background technique [0002] At present, the perspiration fastness enhancer products sold on the market are basically applied to textiles, because reactively dyed cotton clothing is particularly prone to fading when exposed to sunlight after exposure to human sweat (composite color fastness to sweat and light: Due to the action of amino acids in human sweat, it will cause photooxidative decomposition reaction to change color and fade), and for the finished clothes sold, the light fastness to sweat is an important indicator for evaluating the quality of textiles. If it does not meet the standard, it may affect The sales volume of finished clothes itself, so the application of perspiration firmness enhancer is very wide. [0003] However, the perspiration fastness enhancers used in t...

Problems solved by technology

[0003] However, the perspiration fastness enhancers used in textiles on the market generally require a higher post-treatment temperature, most of which are above 100°C. Such a high treatment temperature is not suitable for the fur dyeing industry, because if the fur dyeing If the post-processing temperature is too high, it will affect the quality of the skin board itself

In addition, compared with the fur industry, the perspiration fastness enhancers commonly used in the market have complex application processes and harsh conditions, and are not suitable for the post-dyeing treatment of fur dyes.
