Specialty chemicals company Archroma is showcasing new eco-conscious colors and finishes for denim at the Denim Premiere Vision show in Barcelona.

The latest products include an expanded range of applications for the Optisul C liquid dyes, which offer new colors and treatment options on printed fabrics. They will allow designers to create chemical contrasts on printed and coated jeans. The Optisol C products are sulfide-free and allow easier application than current piece dyeing techniques.

To grow their available color palette, Archroma is introducing a new, bright blue sulphur dye called Diresul Pacific Blue RDT. This will be the first in a planned series of bright greens and blues for this year.

Archroma has also recently launched EarthColors dyes, which are derived from agricultural and herbal waste and produce a palette of green, brown, and grey. The dye comes with hang tags to attach to each item of clothing with information on the individual batches of color. The tags incorporate a chip that consumers can access with Near Field Communications technology on their phones and receive tracking and traceability data on each garment.
