Abstract:
The present invention relates to several novel compositions and methods employing infrared radiation, microwave radiation or high voltage polymerization for modifying the surfaces of materials to impart desired characteristics thereto. More particularly, the present invention relates to a method for modifying the surfaces of objects to increase the lubricity, hydrophilicity, hydrophobicity, or biofunctionality of the surface of the object.
Abstract:
Oil and water repellency is conferred upon porous substrates (10) by treatment with a solution of a monomer (16) of the formula: (C.sub.n E.sub.2n+1)(CH.sub.2).sub.x (CHR)OCOCH.dbd.CH.sub.2 where n is an integer; X is 0,1,2 or 3 and R is H or CH.sub.2 --OCOCH.dbd.CH.sub.2. The monomer is polymerized in situ upon the substrate to provide a conformal coating (16') which preserves the porous structure.
Abstract:
A process is disclosed in which low energy electrons are used chemically to graft phosphorous or halogen-rich double bonded molecules and the like into natural and synthetic materials to render the same flame retarding.
Abstract:
The present invention relates to a fiber treatment agent for electron beam fixing that contains an acrylic-modified organopolysiloxane (A) having two or more acrylic groups per molecule, as represented by the following general formula (I). MaMAbDcDAdTe (I) (in the general formula (I), M=R1R2R3SiO1/2, MA=R4R5R6SiO1/2, D=R7R8SiO2/2, DA=R9R10SiO2/2, T=R11SiO3/2, R1 to R11 each independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or a phenyl group, R4 and R9 each independently represent a monovalent hydrocarbon group represented by the following general formula (II), a, to d each independently are 0 or a positive integer, e is an integer of 0 to 3, c+d is an integer of 10 to 1000, b+d is an integer of at least 2, and a+b is an integer equal to e+2.) (in the general formula (II), n is an integer of 1 to 3.)
Abstract:
Cotton and cotton/polyester blended fabrics are impregnated with aqueous solutions of certain water-soluble monomers and each treated fabric subsequently exposed to near-ultraviolet light thereby initiating polymerization of the monomer on and/or within the yarn and fiber structure. The resulting textiles have improved physical and chemical properties, among which are dyereceptivity, moisture-regain, and personal comfort.
Abstract:
There are disclosed novel copolycondensed vinylphosphonates and a process for their preparation. These products may be used as flame retardant monomers and are especially suitable for flame retarding textiles and a variety of other flammable substrates.
Abstract:
In one embodiment, the present invention relates to silicone-fixed fibers including fibers and silicone fixed to the fibers. The silicone includes an acrylic-modified organopolysiloxane (A) having two or more acrylic groups per molecule. A rate of decrease in the amount of Si after the silicone-fixed fibers are washed 10 times is less than 50%. The present invention relates to a method for producing silicone-fixed fibers. The method includes coating or impregnating the fibers with a fiber treatment agent containing silicone, and irradiating the fibers coated or impregnated with the fiber treatment agent with an electron beam so that the silicone is fixed to the fibers. The silicone includes an acrylic-modified organopolysiloxane (A) having two or more acrylic groups per molecule. Thus, the present invention provides silicone-fixed fibers that include fibers to which silicone is fixed by electron beam irradiation and have a good texture even after washing, and a method for producing the silicone-fixed fibers.
Abstract:
The invention relates to fabrics, comprising fibers and a coating that is covalently bound on the surface of the fibers, characterized in that the fabrics are temperature-stable at 200° C. The invention further relates to methods for the production thereof, fuel cells and gas diffusion layers comprising the fabrics, and to the use thereof in fuel cells and gas diffusion layers.
Abstract:
The present invention provides a process for flame-proofing synthetic textiles which comprises passing a textile through an aqueous padding solution containing a polycondensed vinylphosphonate monomer and curing said monomer on said textile, and thereby rendering the textile flame retardant. The present invention also includes the flame retardant textile produced by the process.
