Circular Systems, Tintex Collaborate for Low-Impact Premium Knits Collection

Circular Systems, a materials science company based in Los Angeles, has partnered with Tintex, a Portuguese sustainable textile company, to launch a premium knits collection designed with Texloop RCOT Primo recycled cotton yarns using Tintex’s Colorau natural dyeing processing.

The companies said the collection utilizes some of the lowest-impact materials and processing available on the market. The collaboration employs a patented process that replaces synthetic dyes with natural extracts and combines fabric milled with yarns with up to 50 percent recycled cotton.

Circular Systems and Tintex noted that dyeing is one of the most polluting parts of the textile industry. They cited World Bank estimates that 17 percent to 20 percent of industrial water pollution comes from textile dyeing and finishing treatment given to fabric. Some 72 toxic chemicals have been identified in water solely from textile dyeing, 30 of which cannot be removed, they said.

The Colorau natural dyeing process incorporates compounds of natural origin like plants into substrates to produce functional, ecological and sustainable technology. This process also eliminates potentially toxic effluents generated by synthetic dyestuffs.

The use of low temperatures in the dyeing process and the substitution of traditional auxiliaries with natural occurring alternatives also contribute to the overall process’ impacts reduction. Tintex said there is no sacrifice in color durability, as Colorau has natural extracts with inherent color fastness properties that can be also antimicrobial. The collection will be available in thyme, chestnut tree, gambier and morus tinctoria colors.
