The medical nerve graft is formed from catheter or catheter and fibre scalfold, and is characterized by that at least one of catheter and fibre scalfold contains silk bambycin protein component. Its preparation method includes the following steps: making natural silk into silk bambycin protein fibre; preparing said silk bambycin protein fibre into catheter containing silk bambycin protein, and combining the catheter and fibre scalfold.

The invention relates to a method for restraining and eliminating fluorescence of a textile product, comprising a chlorine dioxide fluorescence-eliminating method, a chlorine dioxide / sodium chlorite fluorescence-eliminating method and an acetyhydroperoxide fluorescence-eliminating method; the methods can effectively restrain or eliminate the fluorescence on the textile product made of cellulose fibre or protein fibre, and the processed textile product has high intensity and little damage; the method not only can be used for eliminating the fluorescence of the textile product, but also can be used for stripping processing of colored textile products.

The invention discloses a method for making edible artificial sausage casings by enzymatically decomposing collagen fibers. The method successfully uses protease to moderately hydrolyze animal leather with protein activity to obtain delicate long collagen fibers, and through grading Grinding, high-pressure spinning, mixing and other processing steps make the collagen fibers more subdivided and softer, and obtain longitudinal strips of collagen fibers. The collagen fibers are braided and shaped by a circular cross braiding machine, and then shaped with ammonia gas. After drying and qualitative treatment, it is made into seamless, transparent, thin and soft tubular casings. The casings produced by this method mainly contain 50-60 parts by weight of collagen protein and have sufficient compressive strength. When used in sausage production, There will be no tearing phenomenon, and good edibility and palatability are obtained. The performance of the casing is especially suitable for the use of medium and high-end western-style sausages and high-speed automatic sausage filling machines.

The invention relates to a recovery method of an N-methylmorpholine oxide (NMMO) solvent in a process of generating regenerated protein fibre by a solvent method in a spinning technology. The technical scheme of the invention is designed as follows: NMMO aqueous solution with the mass concentration of 50% is taken as a coagulating bath of the regenerated protein fibre; the circulation of the coagulating bath is optimally controlled so that the mass concentration of the coagulating bath of the NMMO aqueous solution in a coagulating bath-loading container is controlled to be 50%; and multiple impurities in recovery liquid, namely a coagulating bath solution, are removed through rough filtration, microporous membrane microfiltration, anion exchange resin treatment, cation exchange resin treatment and hydrogen peroxide oxidization, thereby achieving the recovery of the NMMO solvent.

The invention discloses a synthetic fiber containing animal hair protein, composed of protein and poval, where the protein is a separation one extracted from the animal hair and the content of the protein in the synthetic fiber is 1%-25% or 40%-90%. It also discloses a method to make the synthetic fiber. It uses not only the animal hair but also human broken hair as raw material, thus further enlarging the raw material source of making fiber, and the made fiber does not contain unnecessary inorganic chemical composition and will not produce environmental pollution in the making course.

The present invention relates to a process for the aqueous extraction, fractionation and enzymatic treatment of oilseed materials to generate valued products with no significant low value by-product or waste streams. In particular, the fractionation scheme generates a protein-fibre feed ingredient principally for use with ruminant animals and a second dephytinized high protein fraction. The dephytinized high protein fraction has value as feed ingredient for a variety of species of animals.

The invention provides protein cellulose microparticles. These microparticles comprise cellulose nanocrystals and one or more peptides, one or more proteins, or mixtures thereof, wherein the nanocrystals aggregate with the peptides and / or proteins to form microparticles. In embodiments, the microparticles comprise silk fibroin, and advantageously, the silk fibroin is hydrophobic and lipophilic. The invention also provides cosmetic products comprising these microparticles. In advantageous embodiments, these cosmetic articles comprise a water-in-oil emulsion or a lipophilic medium. Finally, the invention also provides a method for preparing the microparticles.

The present invention relates to artificial organ, in particular it relates to a natural flexible synthetic fibre and protein fibre blended artificial blood vessel with good biological modification potential energy. The natural flexible synthetic fibre is the fibre made up by using two polyester chip with different contraction rates through the processes of mixing, melting and spinning and having cyclic tortuous property, so that it has natural flexible property. The production process of said invented artificial blood vessel made up by blending the above-mentioned natural flexible synthetic fibre and protein fibre is similar to that of other general artificial blood vessel, but said invented artificial blood vessel has higher strength, good vessel wall permeability and good tissue compatibility.
