The green transformation of textile dyeing and finishing is accelerating. Low-temperature and water-saving surface-active agents are being widely adopted and implemented. 

1.The pollution control pressure in the dyeing and printing industry has intensified, and the shortcomings of traditional auxiliaries, such as high water and energy consumption, have become more prominent.
In the traditional processes of degumming, refining and dyeing of cotton and linen fabrics, ordinary surfactants are used, which require high-temperature operations of 60-80℃. Each time the fabric is washed, a large amount of water is consumed, and the wastewater contains a large amount of difficult-to-degrade organic substances. The cost of wastewater treatment remains high. The discharge limits for dyeing wastewater in various regions have been continuously tightened. Many processing enterprises have reduced production capacity due to restrictions on energy consumption and pollutant discharge indicators, forcing the upstream auxiliaries system to undergo a comprehensive upgrade. Low-temperature, low-foaming and easily degradable special surfactants have become the core materials for the transformation. 

2. Innovation in molecular blending technology enables efficient impurity removal and uniform dyeing at room temperature
The new textile-specific surfactant is precisely blended with hydrophilic and lipophilic groups, allowing for the removal of fabric oils, dyes, and impurities within the temperature range of 20-35°C. No boiler heating is required, and the overall energy consumption of a single production line is reduced by 75%. The product's low-foaming characteristic solves the problems of traditional additives' foam accumulation and water consumption during rinsing, reducing the fabric rinsing water usage by nearly 40%, shortening the cleaning process time by half, and directly enhancing the daily processing capacity of the printing and dyeing factory, suitable for large-scale clothing and home textile fabric continuous production lines. 

3. Compatible with various types of fiber fabrics, meeting both hand feel and ecological standards
This series of surface active agents covers the processing needs of all types of fabric materials including cotton, linen, polyester, and regenerated cellulose. During the pre-treatment stage, they do not damage the fiber strength. In the dyeing process, they enhance the uniformity of dye attachment. The finished products are soft, skin-friendly, and free of any hard residue. The raw materials are derived from plant-based renewable substances and do not contain phosphorus or heavy metals. The wastewater can be discharged up to standard through simple sedimentation. It fully complies with the export certification standards for ecological textiles and is suitable for the formula modification requirements of foreign trade home furnishing and high-end clothing manufacturing enterprises. 

4. The green dyeing and finishing standards have been implemented, and water-saving type surface active agents are undergoing a wave of large-scale replacement.
The new version of the environmental protection norms for textile auxiliaries in China has been officially implemented, mandating that new printing and dyeing production lines should prioritize the use of low-temperature degradable auxiliaries. Downstream printing and dyeing enterprises are accelerating the elimination of outdated petrochemical-based surface active agents, and the procurement structure of auxiliaries is continuously adjusting. With the release of the production capacity of alkyl polyglucosides and amino acid-based textile surface active agents in China, the supply stability has improved, and the procurement prices have steadily declined. It is expected that within three years, the penetration rate of low-temperature water-saving type surface active agents in the printing and dyeing industry will exceed 55%, promoting the implementation of green and low-carbon transformation in the textile industry.
