ANN ARBOR – US research firm Kraig Labs has spun its first composite bio-engineered spider silk and Pima cotton yarn as it looks to advance the genetics and robustness of its technology for future textile manufacture.
The production of these bio-engineered yarns, first designed in late 2022, has allowed the company to improve the silk cutting, washing, and opening of the new composite yarns – ready for in-house scale-up.
Robust, bio-engineered silk fibres have been put forward as a candidate to replace synthetic textile fibres in future.
