Abstract: A process obtains an aged or faded effect on garments made of protein fibers such as wool, cashmere and silk. Granules of inert materials, which are particularly light in order not to damage very fine fibers, are introduced into a tumbler. The garments were previously treated with a chemical product commonly referred to as “dye retardant” for inhibiting dyeing of the fabric. The tumbler is pre-arranged so that the chemical product does not migrate through holes or openings. Raw confectioned garments that are to be treated, such as jerseys or outerwear, are introduced into the tumbler. The garments are extracted from the tumbler at the end of migration of the chemical product for inhibiting dyeing of the outer surface of the garments by the granules and steamed in an autoclave to fix the chemical process of the product for inhibiting dyeing of the outer surface of the garments. The garments are then dyed with a specific selection of dyes that must be defined each time according to the desired result.
Abstract: Described are compositions and methods relating to the treatment of keratinous fibers and textiles comprising such fibers with enzymatically-generated peracids in aqueous media. The treatment has beneficial effects, including reducing felting, increasing dye uptake, and reducing prickling tendency.
Abstract: Useful materials are produced from keratin containing raw materials by a process that includes gentle lanthionization of cystine disulfide bonds. Hydratable materials are produced for use in medical and cosmetic applications.

Abstract: A process for treating a textile fabric to impart or enhance at least one property of the fabric comprising:
introducing the fabric into an aqueous formaldehyde containing solution to provide a wet pickup of an effective amount of the solution by the fabric, applying to the fabric an effective amount of a catalyst for catalyzing a reaction between formaldehyde and the fabric;
thereafter exposing the wet fabric to a temperature of at least about 300° F. to react the formaldehyde with the fabric to impart or enhance the property of the fabric before there is a substantial loss of formaldehyde from the exposed fabric.
Abstract: The present invention provides regenerated collagen fibers which have light color and excellent touch in wet conditions and which can be formed into desirable shape with the shape being maintained properly. The present invention also provides regenerated collagen fibers whose foul odor generated in thermal treatment can be inhibited.
The present invention relates to regenerated collagen fibers obtained by treating collagen with a monofunctional epoxy compound and an aluminum salt.
The present invention also relates to a process for preparing regenerated collagen fibers which comprises treating collagen with a monofunctional epoxy compound, and then treating the same in such a way that 2 to 40% by weight of an aluminum salt converted to an aluminum oxide (Al2O3) basis is contained to said collagen.
Abstract: Compositions are described with organopolysiloxanes which contain crosslinked units and are further crosslinkable. The compositions further contain reaction products of diepoxides and diamines. They are useful for treating fiber materials, especially textile sheet materials, and can be applied thereto in the form of aqueous solutions or dispersions. Textiles which are 50 to 100% by weight wool and have been finished with the compositions exhibit low shrinkage and low felting tendency during washing operations.

Abstract: A durable press process for rayon fiber-containing fabrics comprising treating a rayon fiber-containing fabric with an aqueous mixture containing a high concentration of formaldehyde, and a catalyst capable of catalyzing the crosslinking reaction between formaldehyde and the rayon, wherein the concentration of the formaldehyde is sufficient to produce a durable press fabric without substantially shrinkage of the treated fabric, followed by heat curing the treated fabric to produce a durable press rayon fabric without substantial shrinkage.
Abstract: A composition is disclosed that comprises non-hydrolyzable, block, non-(AB)n type copolymers comprising units of the formula {XR2[(SiO(R1)2]xSi(R1)2R2X}, units of the formula {YO(CaH2aO)bY}, and linking groups —NR3—, wherein R1 is alkyl, R2 is a divalent organic moiety, X and Y are independently selected divalent organic groups formed by the ring opening of an epoxide, R3 is selected from the group consisting of alkyl, aryl, aralkyl, oxygen-containing alkyl, oxygen-containing aryl, and oxygen-containing aralkyl, a=2 to 4, b=2 to 100, and x=1 to 500.
Abstract: This present invention provides regenerable antimicrobial animal fiber materials and methods for preparing the same. Such animal fiber materials are prepared using an aqueous finishing process to covalently attach a heterocyclic N-halamine to an animal fiber material. Once prepared, the finished animal fiber materials of the present invention have antibacterial activity against pathogenic microorganisms. Moreover, the antibacterial activity of such animal fiber materials can be regenerated by washing with a chlorine containing solution.
