New Polypropylene Fabric Takes Dye Like Polyester
The announced material could widen polypropylene's use in apparel and footwear, with no commercial timeline disclosed yet.
Updated on Nov. 3, 2026 in Materials Science
Japan-based polyolefin maker Prime Polymer and US biomaterials company Newlight Technologies have jointly developed a polypropylene-based textile material that can be dyed to a degree comparable to PET, using conventional disperse dyeing systems. The material combines polypropylene with Aircarbon PHB, a biomaterial produced by microorganisms that convert methane. This is an announced development; commercial-scale timelines and production capacities have not been disclosed.
Why it matters
Polypropylene is cheap and light but has limited ability to absorb conventional dyes, which has kept it out of mainstream apparel and footwear. Pairing it with a biomaterial that solves the dyeability problem points toward a route for polypropylene to compete more directly with polyester in performance textiles.
The companies report dyeability comparable to PET using conventional disperse dyeing systems and a lower weight than polyester. Specific dye-uptake, colorfastness and weight measurements were not provided in the announcement.
The players
Prime Polymer
A Japan-based polyolefin manufacturer whose polypropylene alloy design and compounding expertise underpins the new textile material.
Newlight Technologies
A US-based biomaterials company whose Aircarbon PHB platform, made by microorganisms converting methane, is combined with polypropylene in the new material.
The details
Polypropylene is a plastic whose molecules resist the chemical bonding that most textile dyes rely on, which is why it has been hard to color. The companies combined Prime Polymer's polypropylene alloy design and compounding know-how, meaning blending the plastic with other materials to change its properties, with Newlight's Aircarbon PHB, a biomaterial made by microorganisms that consume methane. The resulting compound is made into pellets, spun into yarn, and then knitted or woven into fabric.

The Tech Race
The development positions polypropylene as a challenger to PET in performance apparel, footwear and technical textiles by targeting its long-standing dyeability limit. Multiple global brands are reportedly evaluating the material for footwear, performance apparel, socks and technical textiles.
Brands evaluating the material for footwear, performance apparel and socks could eventually bring polypropylene-based garments to market, but no availability or pricing has been announced. Consumers should not expect products using this material on shelves until commercial timelines are disclosed.
The takeaway
Watch for the companies to disclose commercial-scale production capacity and named brand launches, which would show whether the dyeability gain translates into products. Quantitative dye-uptake and durability data from independent testing would also indicate whether the material can match PET in practice.
