As we approach Interdye China 2025, we are excited to welcome you to our booth for in - depth discussions. Our booth number is C652 in HALL2. During the preparation for this exhibition in Shanghai, we've noticed that several of our clients have been inquiring extensively about denim washing chemicals.

Denim washing is a crucial process in the garment industry, and the use of various chemicals plays a significant role in achieving the desired look and quality of denim products. This article will explore some of the key chemicals used in denim washing, namely Anti - back staining (ABS), enzymes, Lycra protector, Potassium Permanganate Neutralizer, and Zipper Protector.

 

Anti - back staining (ABS)

ABS is an essential chemical in denim washing. There are two types available: Paste and Powder. The ABS paste has a concentration ranging from 90 - 95%. Conventionally, it is diluted around 1:5. However, some customers may have special requirements for a dilution ratio of 1:9, which is still manageable. It is important to note that this product is in a paste - like state at temperatures below 30 degrees Celsius. When the temperature rises above 30 degrees, it turns into a liquid, but its performance remains unchanged. After thorough stirring, it can be used without any issues.

On the other hand, ABS powder has a concentration of 100%. It comes in two colors, white and yellow. Some customers may have specific color requirements for compounding. Currently, both the paste and powder forms of ABS are regularly exported to Bangladesh in a certain quantity, indicating their importance in the global denim washing market.

 

Enzyme

Enzymes are widely used in denim washing processes. There are granular enzymes, powder enzymes, and liquid enzymes.

Among granular enzymes, products like 880, 838, 803, and Magic Blue have different characteristics. 880 and 838 are anti - fading enzymes with a slight snowflake effect, and 838 offers a higher cost - effectiveness. 803 has a slight anti - staining effect and a very good snowflake effect. Magic blue is a cold water bleaching enzyme, and its bleaching effect is better than the traditional salt frying process.

 

For powdered enzymes, 890 is a neutral cellulose enzyme with good performance, but its high price is due to imported raw materials. 688 is a stone - free enzyme that can achieve the stone - grinding effect, and AMM is an eco - friendly enzyme that can replace pumice stone without the need to add more water.

 

Liquid enzymes are mainly polishing enzymes, deoxygenases, and acid enzymes. Granular and powdered enzymes have longer storage times, while liquid enzymes are generally best used within 3 months and are usually preferred by end customers. The dosage and concentration of enzymes are crucial as they are closely related to the price. Also, the reference value of enzyme activity is not very strong because different companies have different testing standards and methods.

 

Lycra protector

There are two types of Lycra protectors: anionic (SVP) and cationic (SVP+). The anion content is around 30%, and the cation content is around 40%. The cationic Lycra protector not only protects spandex but also has anti - slip properties, making it more versatile in applications related to denim with Lycra.

 

Potassium Permanganate Neutralizer

This product has a unique feature. As mentioned in previous communication, it has strong acidity. However, it can be transported without problems as it does not fall into the category of dangerous goods. It is being exported monthly, indicating its demand in the denim washing industry.

 

Zipper Protector (ZIPPER 20)

Zipper Protector (ZIPPER 20) is mainly used in wet finishing processes such as washing, sandwashing, reactive dyeing, pigment dyeing, and enzyme washing. Its main function is to prevent metal zippers or metal hooks from fading or changing color during these processes, thus maintaining the overall appearance and quality of the denim garment.

 

In conclusion, these various denim washing chemicals play distinct and important roles in the denim manufacturing process. Their proper use and understanding are essential for the garment industry to produce high - quality denim products.
