Problems solved by technology

In the existing desizing process, there are certain shortcomings. Both hot water desizing and soap oil desizing cannot remove the textile size on the fabric, and the hand feels hard; alkali desizing and oxygen bleaching desizing can effectively remove the fabric The surface size is removed cleanly, but the strength damage to the fiber is relatively large. This method of desizing has high COD emissions and has a great impact on the environment; desizing enzyme desizing can effectively decompose starch size, but it cannot decompose chemical size. And impurities such as pectin on the yarn cannot be removed
Combining the above several desizing methods has the following disadvantages: 1. The desizing rate is not high, and the hand feels hard; 2. The COD emission is high, which has a great impact on the environment; 3. The strength of the fiber is large; 4. The yarn is fruity. Colloid and other impurities are not removed cleanly

Abstract

The present invention relates to a denim garment desizing refining finishing agent and a preparation process thereof. The finishing agent includes the following raw material ingredients by weight: 400-500 parts of a wide-temperature desizing enzyme, 50-100 parts of pectate lyase, 300-400 parts of alcohol ether, 0-3 parts of a defoamer and 50-250 parts of deionized water. Compared with the existingtechnology, the denim garment desizing refining finishing agent can still play high efficiency in the use of low temperature, and is more energy-saving and environmental-friendly, and the denim garment desizing refining finishing agent has a good impurity removal effect and better hand effect.

Description

technical field [0001] The invention relates to a finishing agent for clothes, in particular to a desizing and scouring finishing agent for denim garments and a preparation process thereof. Background technique [0002] Denim originated in the United States, and the first denim was born in the middle of the 19th century. After hundreds of years of development, denim is still prosperous after a hundred years of wind and rain, and the market is getting bigger and bigger, because denim fabrics and clothing It is suitable for all ages and has strong versatility. Denim clothing has also changed from the initial tooling to the current fashion trend item. As a fashion item, denim will never be outdated. Every cow lover has at least one denim clothing in his wardrobe. [0003] Denim warp yarns have higher requirements on physical and mechanical properties such as strength, elongation, and elasticity than weft yarns. Because the warp yarn is dyed and sized before weaving, the proce...
