An object of the present invention is to provide a method capable of producing a protein fiber in which shrinkage at the time of first contact with moisture after production is more reliably suppressed and generation of crimp is also suppressed. A method for producing a protein fiber according to the present invention includes: a pre-shrinking step of shrinking a protein fibril in a relaxed state after drawing and before being wound; a winding step of winding the protein fibril subjected to the pre-shrinking step to obtain a wound product; and a post-shrinking step of shrinking the protein fibril subjected to the winding step in a relaxed state.

Disclosed is a method of crosslinking hair or other keratin fibers by (i) providing a crosslinking agent comprising an oxidized sugar having at least two aldehyde groups; and (ii) infiltrating a plurality of non-crosslinked hair or other keratin fibers with the crosslinking agent under conditions effective to cause protein molecules contained in the non-crosslinked hair or other keratin fibers to become crosslinked, thereby yielding a population of crosslinked hair or other keratin fibers. The protein molecules include amine groups that react with the aldehyde groups of the oxidized sugar to yield the crosslinked hair or other keratin fibers. Also disclosed are formulations for crosslinking hair or other keratin fibers and methods of using the formulations to treat human hair to maintain a desired three dimensional structure. This formulation includes a crosslinking agent having a plurality of oxidized sugars having at least two aldehyde groups or mixture thereof.

The invention provides fabrics that incorporate a cold-adapted trypsin derived from a fish or a crustacean, which trypsin inactivates viruses. The fabrics of the invention may be used in the production of various items of self-sterilizing protective equipment including gowns, sheets, curtains, surgical hats, surgical booties and protective facemasks.

Disclosed is a method of crosslinking protein fibers, including wool fibers, by (i) providing a crosslinking agent including an oxidized sugar mixture having a plurality of different oxidized sugars of different molecular lengths and having at least two aldehyde groups (e.g., oxidized soy flour sugars); and (ii) infiltrating a plurality of non-crosslinked protein fibers with the crosslinking agent under conditions effective to cause protein molecules contained in the non-crosslinked protein fibers to become crosslinked. This method yields a population of crosslinked protein fibers, where the protein molecules of the non-crosslinked protein fibers include amine groups that react with the aldehyde groups of the oxidized sugars to achieve the crosslinking of the protein molecules to yield the crosslinked protein fibers.

This patent document discloses a method of fabricating an electrically conductive fiber coated with polythiophene and a carbon material. The low-cost method is amenable to modifications to suit the practical needs in various applications.

The present disclosure provides improved long uniform recombinant protein fibers with desirable physical traits. The present disclosure also provides compositions derived from the long uniform recombinant protein fibers.

A functional cashmere fiber includes a cashmere fiber, a boron-doped TiO.sub.2 layer and a carboxymethyl cellulose (CMC) binder. The CMC binder binds the boron-doped TiO.sub.2 layer on the cashmere fiber such that the boron-doped TiO.sub.2 layer at least partially covers the cashmere fiber. The functional cashmere fiber provides self-cleaning function under visible light and high washing stability.
