Prime Polymer, Newlight Develop PET-Dyeable Polypropylene Fiber
Huntington Beach – November 02, 2026 -- Japan-based Prime Polymer and U.S. biomaterials company Newlight Technologies have developed a polypropylene textile material with dyeability comparable to polyester (PET). The material targets the limited dyeability that has held back polypropylene fiber in apparel and footwear.
Polypropylene and Aircarbon PHB alloy accepts conventional disperse dyes
The material combines Prime Polymer's polypropylene alloy design and compounding technology with Newlight's Aircarbon® PHB. Newlight produces this biomaterial with microorganisms that convert methane.
The companies say the alloy can be processed from compound pellets into yarn, then knitted or woven into fabrics. It can be dyed with conventional disperse dye systems, the same class of dyes used for polyester. Both companies have demonstrated conversion of the material into yarn and textile structures.
