Forward-thinking YKK trials waterfree dyeing process
Zip manufacturer YKK is working on a new ‘eco’ dyeing process using supercritical fluid dyeing (SFD) technology, which the company says will allow it to use almost no water in the dyeing process.

The technology uses carbon dioxide (CO2) as a dyeing medium, and this can then be collected and recycled. Another advantage of using SFD is that it does not require drying, and therefore is expected to contribute to the reduction of energy use.

The process is being trialled at its factory in Kurobe, Japan.

“For the apparel industry, major issues include the reduction of water usage, elimination of discharge of hazardous chemicals and waste water in production processes. Major brands, which include our customers, are joining the Detox campaign aimed at the elimination of water pollution and discharge of hazardous substances.

“YKK pays a great deal of attention to environmental aspects of the production process. Reducing water usage and eliminating wastewater in the manufacturing process of fastening products is becoming increasingly important to us.”

Headquartered in Japan, YKK operates in 71 countries.

A number of apparel firms and manufacturers are also trialling the SFD process, including Nike with FENC, Adidas and Formosa Taffeta.
