Customized Acidic Leveling Agent for The Textile Dyeing And Printing Industry

Customer Requirements: 

A large-scale textile dyeing and printing enterprise mainly produces high-end nylon fabrics for luxury clothing. During the dyeing process, they encounter the problem of color banding, especially when dealing with large areas of single-color fabrics. Due to the differences in nylon fibers, the dyeing rate is inconsistent, resulting in obvious color unevenness in the finished products, which seriously affects product quality and brand image. At the same time, the enterprise hopes to optimize the dyeing process and reduce energy consumption costs while ensuring dyeing quality.

Customized Solution: 

Our R&D team conducted an in-depth analysis of the enterprise's dyeing process, equipment, and existing raw materials. We then customized an acidic leveling agent for them. In the formula, we adopted high-concentration technology, precisely blending fatty amine polyoxyethylene ether with high-efficiency dispersants to achieve rapid cold water dissolution at low temperatures, significantly saving dissolution time and energy consumption. Additionally, we introduced the bio-based material sodium lignosulfonate, which not only enhanced the product's environmental performance but also improved the stability of dye dispersion.

Implementation Effect: 

After using the customized leveling agent, the enterprise's dyeing process was significantly optimized. The dyeing process started at 60°C, compared to the previous 90°C or higher, saving a large amount of steam per batch. The color banding problem was effectively solved, reducing the rate of defective products due to color unevenness. The synchronous dyeing property of the fabric was greatly improved, and the color vividness and fullness were significantly enhanced. After calculation, the comprehensive cost was reduced by about 15%, and production capacity increased by 20%. The enterprise's competitiveness in the high-end textile fabric market was further consolidated, and its products successfully entered the supply chains of multiple international luxury brands.
