Abstract
Silk performance apparel and methods of preparing the same are disclosed herein. In some embodiments, silk performance apparel includes textiles, fabrics, consumer products, and other materials that are coated with aqueous solutions of pure silk fibroin-based protein fragments. In some embodiments, coated apparel products exhibit surprisingly improved moisture management properties and increased resistance to microbial growth.
Claims48
An article comprising a fiber or yarn having a coating, wherein the coating comprises silk based proteins or fragments thereof having an average weight average molecular weight selected from about 5 to about 10 kDa, about 6 kDa to about 16 kDa, about 17 kDa to about 38 kDa, about 39 kDa to about 80 kDa, about 60 to about 100 kDa, or about 80 kDa to about 144 kDa,
- wherein the silk based proteins or fragments thereof have a polydispersity of between about 1.5 and about 3.0, and
- wherein the silk based proteins or protein fragments thereof, prior to coating the fiber or yarn, do not spontaneously or gradually gelate and do not visibly change in color or turbidity when in a solution for at least 10 days.
An article comprising:
- a synthetic fiber or yam;
- and
- a coating comprising silk based proteins or fragments thereof having an average weight average molecular weight selected from about 5 kDa to about 144 kDa and a polydispersity ranging from 1 to about 5.0,
- wherein the article is a fabric, and
- wherein the silk based proteins or protein fragments, prior to coating the fabric, do not spontaneously or gradually gelate and do not visibly change in color or turbidity when in a solution for at least 10 days.
