That was how I stumbled upon soy fibre. According to the website of a clothing line named Baby Soy, Henry Ford of Ford Motor first talked of soy fibre in the 1940s and was photographed wearing the first known soy suit and tie. Technological breakthrough in 1999 made mass production of soy fibre realistic and economically sound. The invention of soy textile was awarded the gold prize by World Intellectual Property Organization (WIPO) in 2003.
Soy fibre is manufactured from extracting the proteins from leftover dregs from soya oil/ tofu/ soy milk production, turning waste into useful products. The resulting textile is sustainable, utilising renewable natural resources.
In addition to being environmentally friendly, soy textile has the same warmth retention as wool and better moisture transmission than cotton, making it very comfortable to wear. Thus, ideal for baby clothing as it keeps babies warm and dry. It is also soft, smooth, and light; with silky lustre and a cashmere feel...at cotton prices!
While Argentina is a major producer and exporter of soya, most are sold in the form of primary products. This soy clothing retailer I have found is a company based in California.
