    摘要: Textile fibers are treated with enzymes in the absence of surfactants, with the effect of increasing the wettability and absorbency of the fibers. The enzymes are pectinases, cellulases, proteases, lipases or combinations thereof. The wetting properties of cotton fibers are found to be most substantially improved by treatment with a mixture of cellulase and pectinase. The effects of five hydrolyzing enzymes on improving the hydrophilicity of several polyester fabrics have been studied. Four out of the five lipases studied improve the water wetting and absorbent properties of the regular polyester fabrics more than alkaline hydrolysis under optimal conditions (3N NaOH at 55° C. for 2 hours). Compared to aqueous hydrolysis, the enzyme reactions have shown to be effective under more moderate conditions, including a relatively low concentration (0.01 g/L), a shorter reaction time (10 minutes), at an ambient temperature (25° C.). Contrary to the results with alkaline hydrolysis, the improved water wettability is accompanied by full strength retention. Lipase has also shown to be effective in improving the wetting and absorbent properties of sulfonated polyester and microdenier polyester fabrics.

    摘要: Copolyesters containing monohydroxyamine salts of oxalic acid or dihydroxyamine salts of organic aliphatic dicarboxylic acids in which the carboxyl groups are separated by at least two carbon atoms can be formed into fibers that dye to deep shades with acid type dyes. From about 1 to about 15 mol percent of the amine salt is used based on the total mols of acid units in the polyester exclusive of the acid in the amine salt itself. The invention encompasses random copolyesters as well as block copolyesters, both of which have improved anionic dyeability. Fibers of such copolyesters can be dyed to deep shades in solvents such as chlorobenzene or in strong acetic acid solutions. Dyeing can also be accomplished in aqueous dye solutions with or without the use of pressure. Dyeing in acidic medium gives excellent results.

    摘要: The dimensional stability, wrinkle resistance, smooth drying characteristics and total shape retentivity of cellulosic material such as cotton fabrics are improved by impregnating the fabric with an aqueous solution of a monomeric compound which has at least one active hydrogen and reacts with formaldehyde, e.g., urea, exposing the impregnated fabric to an atmosphere containing formaldehyde vapors in the absence of a catalyst until a creaseproofing amount of an at least partially polymerized, substantially water-insoluble condensate (such as an amideformaldehyde condensate) is affixed to the fabric without, however, effecting any substantial amount of cross-linking with the cellulosic fiber. The thus-exposed fabric is thereafter postheated in an inert gaseous atmosphere also in the absence of a catalyst to further polymerize and cross-link the fabric.

    摘要: A process for decreasing the flammability of textiles comprising a cellulosic fiber component and preferably a nitrogen-free thermoplastic fiber component which comprises treating the cellulosic fiber component with a condensate or a physical admixture of an allylurea and a phosphine/formaldehyde condensate such as a tetrakis (hydroxymethyl)-phosphonium salt to introduce allyl groups into the cellulosic component, and subsequently halogenating, preferably brominating, the allyl groups thus introduced.

    摘要: This invention relates to a process for modifying keratinous material, and, in particular, to a process for rendering the material resistant to shrinkage and to a process for imparting durable press characteristics to the material. This process comprises treating the material with a resin having at least two thiol groups per molecule and containing a radical of a polyhydric alcohol, bound to this radical, at least two poly(oxyalkylene) chains, at least two radicals of a thiolcontaining aliphatic carboxylic acid or of a thiol-containing aliphatic alcohol. As curing catalyst a sulfur-containing organic compound is used.
