Kraig Biocraft Laboratories a leader in spider silk-based fibers, has achieved a major milestone by creating a new transgenic silkworm inspired by the Darwin’s bark spider (Caerostris darwini).
This advancement marks a leap forward in the production of high-performance recombinant spider silk, which is known to be over 10 times tougher than traditional para-aramid fibers used in bulletproof vests and other high-strength applications.
By incorporating the genetic elements of Darwin's bark spider silk into its proprietary silkworms, Kraig Labs has developed a scalable system for producing this incredibly tough material.
The new transgenic combines the strength and elasticity of the spider silk with the efficiency of traditional silkworm silk production, enabling the company to pursue commercial-scale production.
Kim Thompson, Founder and CEO, emphasized that this breakthrough showcases Kraig Labs commitment to advancing material science by leveraging nature's best designs. COO Jon Rice expressed optimism for 2025, highlighting ongoing advancements and the company's growing production capacity.
This innovation strengthens Kraig Labs position as a leader in sustainable spider silk-based super materials with vast applications across textiles, defense, medical, and industrial sectors.
