In the textile dyeing process, high water consumption and pollutant discharge have long been issues for the industry. As environmental regulations become stricter, finding better solutions has become a key focus of technological development. Today, we’ll introduce waterless dyeing technology from the perspective of a zipper manufacturer.

1. Limitations of Traditional Dyeing

In textile production, traditional dyeing processes rely heavily on water. Dyeing one ton of fabric often consumes dozens of tons of water and produces a certain amount of pollutants, putting pressure on both environmental management and resource utilization.

2. Principles and Advantages of Waterless Dyeing Technology

To address this industry challenge, SBS has been collaborating with the Chinese Academy of Sciences since 2011 to develop waterless dyeing technology. This method uses supercritical carbon dioxide for dyeing. In its supercritical state, carbon dioxide combines the solvent properties of a liquid with the diffusibility of a gas, allowing dyes to fully penetrate the fabric. Waterless dyeing offers following advantages: ①Completely waterless; ②No auxiliary agents required, with strong dye penetration; ③Fast dyeing speed; ④Uses carbon dioxide as the raw material, which can be collected from industrial emissions and recycled after dyeing.

3. Company’s Technical Capabilities

Currently, waterless dyeing technology has moved out of the laboratory and completed pilot-scale trials, entering a stage of scale industrial application. It has attracted attention from several European brands focused on environmental sustainability.
