Abstract
Silk infused performance apparel and methods of preparing the same are disclosed herein. In some embodiments, silk performance apparel includes textiles, fabrics, consumer products, leather, and other materials that are coated with aqueous solutions of pure silk fibroin based protein fragments. In some embodiments, coated apparel products, textiles, and upholstery, as well as other materials, exhibit surprisingly improved moisture management properties, resistance to microbial growth, increased abrasion resistance, and flame resistance.
