  • Patent number: 7147669
    Abstract: Excellent water repellency and Oil repellency are imparted to a textile by a method including (1) preparing a treatment liquid comprising a water- and oil-repellent agent, (2) adjusting pH of the treatment liquid to at most 7, (3) applying the treatment liquid to a textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile, wherein the water- and oil-repellent agent comprises at least one fluorine-containing compound selected from the group consisting of a fluorine-containing polymer and a fluorine-containing low molecular weight compound, and the water- and oil-repellent agent or the treatment liquid contains a cationic emulsifier and/or a salt.

  • Patent number: 7141076
    Abstract: A hydrolizable polymer-containing textile article and method for producing the same is provided that has been chemically modified by treating the article with certain branched chain amines to reduce the strength of the fibers contained therein, thus rendering the article less prone to the formation of objectionable pill balls, thereby increasing wearer comfort and retaining the desired appearance of the article, and thereby extending the useful life of the article.

  • Patent number: 7090701
    Abstract: Methods of improving shrink-resistance of natural fibers (e.g., wool, wool fibers, animal hair, cotton), synthetic fibers (e.g., acetate, nylon, polyester, viscose rayon), or blends thereof (e.g., wool/cotton blends), or fabrics or yarns composed of natural fibers, synthetic fibers, or blends thereof, involving contacting the fibers (or fabric or yarn) with NaOH, H2O2, gluconic acid, dicyandiamide, and non-ionic surfactant (e.g., Triton X surfactant such as Triton X-100 and preferably Triton X-114), and optionally subsequently contacting the fibers (or fabric or yarn) with protease and non-ionic surfactant and optionally sodium sulfite and optionally triethanolamine and optionally polyacrylamide polymer. The methods do not utilize dichloroisocyanuric acid, chloroamines, peroxymonosulfuric acid, monoperoxyphthalic acid, permanganate, chlorine gas, sodium hypochlorite, or aminoplast resins.

  • Patent number: 7070624
    Abstract: The present invention is directed to a process for separating polyester, and particularly polyethylene terephthalate, from various contaminants and impurities. In general, the process includes the steps of mixing materials containing polyester with an alkaline composition in a mixer. The mixer imparts sufficient energy to the slurry to provide substantially complete, even coating of the polyester containing materials with the alkaline composition and cause saponification of the outer surface of the polyester with the alkaline composition. After reaction in the mixer, the mixture is heated causing some of the impurities to be chemically modified into a more separable form. After heating, the mixture can be washed with water and the polyester can be easily separated from the remaining impurities. Through the process of the present invention, polyester can be separated and recovered from waste materials such as those containing polyvinyl chloride and aluminum.

  • Patent number: 7018421
    Abstract: The present invention relates to a process for preparing synthetic hair fiber comprising halogen-containing synthetic fiber, in which synthetic hair fiber can be evenly dyed at a low temperature in a short period, maintaining excellent fastness, without abnormal shrinking (frizzing) and embrittlement of the fiber due to swelling. The object is attained by dipping the synthetic hair fiber bundle in a solution containing a dye, a carrier (accelerating agent) and a solvent for halogen-containing fiber, and then dyeing at 60° to 90° C.
