Proteinaceous Fibers Patents (Class 8/127.5)
  • Patent number: 8999005
    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.

  • Patent number: 6827746
    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.

  • Patent number: 6749642
    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.

  • Patent number: 6579325
    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.
