Bossa Introduces SaXcell Denim

Bossa is bringing denim made with SaXcell fiber into the market.

For Fall/Winter 2025-2026, the Turkish denim mill introduced Endless Blue, fabric collection made with the regenerated virgin cellulose fiber.

SaXcell is derived from chemical recycled cotton waste. The fiber’s production begins with sorting domestic cotton textile waste into a well-defined waste stream. Non-textile components like zippers and buttons are removed as the waste is grinded into a dry mixture of fibers with different lengths. The dry mixture is chemically decolored, followed by a wet spinning process.

The fiber can be cut to specified lengths, spun into yarns and woven or knitted into fabrics. Coloring can take place at the fiber, yarn or fabric stages.

From hemp to colored cotton, Bossa actively introduces new fibers to their denim fabrics. With SaXcell blended denim, Muge Tunceren, Bossa’s product development manager, said the mill is “able to create denim fabrics not only to meet high standards of quality and performance but also prioritize environmental conservation.”

The Endless Blue collection includes two fabrics: the comfort stretch Organic Cypress Savetrue with 34 percent SaXcell lyocell; and the power stretch FX Metacell Freshblue with 18 percent SaXcell lyocell.

“SaXcell exhibits excellent performance throughout the washing and laundry processes,” said Jordan Nodarse, Bossa Denim designer. “We haven’t encountered any performance issues that differ from other lyocell fibers currently on the market. This is a significant advantage since SaXcell is made from recycled input, unlike recycled cotton, which performs differently compared to its virgin counterpart.”

Nodarse added that the mill has received a lot of interest in SaXcell fiber as the market is looking for recycled cellulosic fibers. “We have several new developments in progress for some iconic sustainable brands”, he said.

“The collaboration between Bossa’s experienced denim manufacturing team and SaXcell’s innovation expertise addresses some of the big challenges of our time; moving from a linear to a circular economy,” SaXcell stated.

The Dutch fiber producer said that PVH Corp., which recently made sample tops with SaXcell fibers, gave positive feedback about the quality of the garments.

Initially a project by a team of researchers from Saxion University of Applied Science in 2011, SaXcell was spun off as a startup in 2015. The company has been scaling its technology since through partnerships with Rieter, a supplier of systems for short-staple fiber spinning, and Birla Cellulose, a producer of man-made cellulosic fiber.
