New Textile Material Enhances Polypropylene Dyeability

Japan’s Prime Polymer and US biomaterials specialist Newlight Technologies have created a new textile material that combines the lightweight properties of polypropylene (PP) with dyeability similar to polyester.

This innovation could significantly broaden the application of PP in apparel and footwear, where its low density, durability, and moisture management have been appealing, but its resistance to conventional dyeing has limited its use.

The new material merges Prime Polymer’s PP alloy design with Newlight’s Aircarbon polyhydroxybutyrate (PHB), a biologically produced polymer. This polymer can be processed into yarns and fabrics that can be dyed using conventional disperse dye systems, achieving color comparable to polyester.

The companies have demonstrated successful yarn production and fabric formation, with mechanical properties suitable for apparel and footwear applications. They are currently collaborating with global brands to evaluate the material for various textile applications.

If successfully scaled, this technology could enhance PP's competitiveness in textile markets typically dominated by polyester and polyamide.
