摘要:
The present invention provides highly safe functional fibers by imparting a novel function to recycled cellulose fibers. The present invention provides recycled cellulose fibers which contain an eggshell membrane hydrolysate. The recycled cellulose fibers according to the present invention may contain about 0.5 part by mass to about 25 parts by mass of the eggshell membrane hydrolysate per about 100 parts by mass of cellulose.
摘要:
A metal adsorbent which can adsorb a wide variety of metals, can conform to various uses, and adsorbs metals in large amounts . Metal adsorbents in various forms, which have the property of highly efficiently adsorbing metals, are produced by (a) a method in which a polyamine polymer is chemically bonded and immobilized to a porous support, (b) a method in which a polyamine polymer is blended into a solution of a raw material for fibers and the mixture is formed into fibers by wet-spinning or dry spinning, and (c) a method in which a polyamine polymer is blended into a solution of a film-forming polymer and the mixture is formed into a film by a method of film formation from solution.
摘要:
A rayon fiber that does not use a halide-based flame retardant, a phosphorous flame retardant or an organic solvent, has excellent flameproofness and launderability and is biodegradable when buried in the soil at the time of disposal, and a method for manufacturing the same are provided. The flameproof rayon fiber according to the present invention contains components of silicon and magnesium, and a compound containing the components of silicon and magnesium is amorphous. This rayon fiber can be manufactured by preparing a viscose solution, adding a solution containing a silicate compound containing an alkali metal to the viscose solution so as to make a silicic compound-added viscose spinning solution containing the alkali metal, performing spinning by extruding the silicate compound-added viscose spinning solution containing the alkali metal through a spinneret into a spinbath containing a sulfuric acid, thus producing a fiber to be treated containing the silicate compound, and treating the fiber to be treated using a magnesium-containing solution in a scouring process or an aftertreatment process.
摘要:
A regenerated cellulose fiber dyeable with disperse dyes, which contains 10-40 wt.% of fine particles of a polyester or a styrene/acrylate copolymer dyeable with disperse dyes and having an average particle diameter of 0.05 - 5µm. When dyed in the form of a mixture thereof with a polyester fiber, it can attain an excellent union dyeing and the dyeing efficiency is remarkably improved because both fibers can be simultaneously dyed.
