Milestone Marks Recombinant Spider Silk’s Move from Scaled Production to a First-of-Its-Kind Performance Textile

ANN ARBOR, Mich., Sept. 29, 2026 (GLOBE NEWSWIRE) -- Kraig Biocraft Laboratories, Inc. (OTCQB: KBLB) (“the Company”, “Kraig Labs”, or “Kraig's”), a world leader in spider silk technology*, today announced the shipment of its first commercial order of recombinant spider silk yarn. The custom-engineered yarn was produced to fulfill a purchase commitment from a globally recognized performance sports brand and is slated for development into a first-of-its-kind performance textile.

This spider silk sale is part of a confidential pilot development program. The program targets one of the most demanding and innovation-focused segments of the athletic apparel market. The yarn has been custom processed to the customer's specifications and has now shipped.

“Completing the delivery of this spider silk yarn is a huge milestone for Kraig Labs,” said Kim Thompson, Founder and CEO of Kraig Labs. “The volume is small by design. This is a precision application, not a bulk order. It is exactly the kind of application where spider silk's real advantages can be highlighted. Strength, flexibility, toughness, and light weight, under conditions pushing materials to their limits. This application is a shining example of how spider silk can transform markets.”

The shipment comes at a pivotal moment for the global textile industry, as fashion and performance brands explore new materials while confronting the challenge of moving promising fiber technologies from laboratory innovation to reliable production. Textile Exchange’s Materials Market Report 2026, published September 22, reported that global fiber production reached a record 139 million metric tons in 2025, with polyester accounting for 59% of total output and 88% of polyester production coming from virgin fossil-based sources. Against that backdrop, the opportunity for emerging performance materials is significant, but so is the challenge: new fibers must deliver differentiated properties while proving they can be produced consistently and integrated into an industry built around enormous volumes of established materials. Kraig Labs’ first commercial shipment represents an important step from material innovation and scaled production toward real-world textile adoption.

Kraig Labs views elite performance apparel as one of the clearest proving grounds for recombinant spider silk. A category where gains in strength-to-weight ratio and durability translate directly into competitive advantage for the athlete.

“High-performance sport is where materials prove themselves,” Thompson continued. “Performance wins. That is the only thing that matters in elite sport. It's about how it performs when everything is on the line, and that's exactly what we intend to prove.”

While the quantity of silk in this shipment is small, Kraig Labs believes the true significance lies in what it represents for the broader athletic and performance textile market. A successful application here demonstrates that recombinant spider silk can meet the exacting technical standards of elite sport, standards few materials, natural or synthetic, are able to satisfy. A validated performance application of this kind opens the door to further engagement with brands across the performance apparel space.

“This is the kind of project that changes the conversation,” Thompson concluded. “When a brand at this level puts our material to the test, the results speak for themselves. We intend for this to be the first of many.”
