Parkdale Mills now owns the Ciclo polyester and nylon biodegradation technology outright. The Gastonia, N.C.-based yarn manufacturer announced Oct. 1 that its Parkdale Advanced Materials subsidiary acquired full ownership of the patented additive, which is designed to let synthetic fibers break down in biologically active environments. The company did not disclose financial terms.

The deal closes an eight-year partnership. In September 2018, Parkdale Advanced Materials and Intrinsic Textiles Group formed Intrinsic Advanced Materials, a joint venture to commercialize Ciclo. The buyout puts the technology entirely under Parkdale's control as the company targets industrial and hygiene nonwovens, geotextiles, filtration, insulation and furnishings — markets where synthetic fiber persistence is a growing compliance and reputational issue.

For suppliers, the commercial significance is the buyer base already attached to the technology. Products incorporating Ciclo are available from Target, Walmart, Costco, Black Diamond, Stella McCartney and Hanes, distributed through a global network of certified fiber, yarn and fabric manufacturers serving apparel, home and hospitality markets.

Davis Warlick, Parkdale's chief operating officer, framed the acquisition as both a customer-value play and a microplastics response. "We are committed to investing in technologies that create value for our customers and address meaningful challenges for our industry and the environment," he said. "We believe Ciclo fibers have the potential to address microplastic fiber persistence at meaningful scale. Our focus now is to continue investing in the technology, develop new applications with our customers, open new markets and broaden adoption so it can deliver greater impact."

Ciclo works at the fiber-manufacturing stage. The additive is incorporated into polyester and nylon during spinning, where it creates pathways that allow naturally occurring microorganisms to break down the polymer in environments with the conditions needed for biodegradation — seawater, soil, wastewater sludge and biologically active landfill. The target problem is fiber persistence after synthetic textiles enter the environment, not rapid decomposition in use.

The technology is compatible with virgin, recycled, biobased and textile-to-textile feedstocks, as well as natural-fiber blends, and preserves manufacturing efficiency, dyeability, durability and recyclability, according to Parkdale. That compatibility matters for mills running recycled polyester programs who cannot afford process disruption or degraded dye uptake.

On the evidence side, Parkdale said independent testing used ASTM and ISO methods across four environmental conditions. In one soil test, treated polyester fibers reached 91.1 percent biodegradation after 1,170 days, per results published on Ciclo's website. Untreated polyester showed no biodegradation over the same period. The study used fertile soil with active microorganisms under laboratory conditions; Ciclo's own site notes that breakdown rates vary in natural settings. Buyers treating biodegradation claims as compliance items should trace each claim to the specific ASTM or ISO method and test condition behind it.

Cheryl Smyre, vice president of Parkdale Advanced Materials, signaled that the expansion goes beyond apparel supply chains. "Our opportunity now is to take Ciclo technology further," she said. "That means expanding adoption among the brands and supply chain partners already using the technology while advancing next-generation applications for markets where synthetic fibers are essential. Microplastic pollution is agnostic to the source. To drive meaningful, lasting change, we must extend the reach of Ciclo polymers beyond traditional textile applications and accelerate innovation across industries."

The acquisition follows recent expansion in home textiles. On Sept. 10, Intrinsic Advanced Materials announced that Advansa is introducing Suprelle fiberfill made with Ciclo fibers for bedding, home and hospitality applications. A separate collaboration with HeiQ Materials pairs Ciclo fibers with functional finishes for cooling, moisture management, freshness and allergen reduction — a combination aimed at performance bedding where function and sustainability claims now compete on the same spec sheet.

Parkdale plans to deploy its yarn manufacturing infrastructure, technical expertise and R&D capabilities to scale the technology. Founded in 1916, the company operates textile, advanced materials and cotton-based health and beauty businesses, with a yarn manufacturing network spanning the United States, Mexico, Central America and South America.

The sourcing decision the news forces: brands and mills weighing microplastics exposure can now license a certified additive from a single, well-capitalized US-based yarn producer with confirmed retail adoption — but any biodegradation claim placed on a hangtag or in an ESG report needs to be tied to the specific ASTM or ISO test data, since lab soil conditions are not real-world conditions.
