Yeh Group Adopts DyeCoo Dyeing Technology

Yeh Group, Thailand, a producer of knit fabrics and garments for sporting and intimate markets, has received exclusive rights to use water-free carbon dioxide (CO2) dyeing technology developed by DyeCoo Textile Systems BV, the Netherlands. 

DyeCoo's dyeing machine features a stainless-steel chamber in which supercritical fluid CO2 rather than water is used to dye textile materials. The supercritical fluid CO2 swells hydrophobic man-made fibers, allowing modified disperse dyes to diffuse within the fiber. Fabric drying and removal of excess dye are performed in the same chamber as the dyeing operation. Recovered dye can be reclaimed and recycled. The process uses half the energy used in traditional dyeing processes, according to DyeCoo.

Yeh Group will market fabrics dyed using the DyeCoo machine under the DryDye™ brand, and reports the fabrics' dye quality and durability equals that of traditionally dyed fabrics.
