    摘要： A textile includes a substrate and a coating applied to a surface of the substrate. The coating includes a plurality of bilayers positioned one on top of the other. Each bilayer includes a first layer including a cationic polymer and a second layer comprising an anionic polymer. The cationic polymer in the first layer includes a polyethyleneimine (PEI), a poly(vinyl amine) (PVAm), a poly(allyl amine) (PAAm), a polydiallyldimethylammonium chloride (PDDA), or a chitosan (CH). The anionic polymer in the second layer includes a poly(acrylic acid) (PAA), a poly(styrene sulfonate) (PSS), a poly(methacrylic acid) (PMAA), a poly(sodium phosphate) (PSP), or a poly(vinyl sulfate) (PVS).

    摘要： A flame retardant resin composition includes a thermoplastic resin, flame retardant reinforced fibers, and a flame retardant. The flame retardant reinforced fibers include cellulosic fibers, a phosphorus compound that is grafted to the surface of the cellulosic fibers, and a polyamine compound that is bound to the phosphorus compound. The flame retardant is a phosphorus-based flame retardant. A method for producing the flame retardant resin composition includes the following: grafting a vinyl phosphate compound to cellulosic fibers by bringing the vinyl phosphate compound into contact with the cellulosic fibers after the cellulosic fibers have been irradiated with an electron beam, optionally followed by electron beam irradiation; binding a polyamine compound to the vinyl phosphate compound, which is grafted to the cellulosic fibers, to form flame retardant reinforced fibers; grinding the flame retardant reinforced fibers; and melt-kneading and pelletizing a thermoplastic resin, the flame retardant reinforced fibers, and a component containing a phosphorus-based flame retardant. This can provide a non-halogen flame retardant resin composition with sufficient flame resistance.

    摘要： A composite textile is provided. The composite textile includes a textile substrate and a thermal material layer formed on the textile substrate. The thermal material layer includes a nanocomposite powder. The nanocomposite powder is composed of a pyrrolidone-containing polymer and an inorganic particle. The pyrrolidone-containing polymer is polyvinylpyrrolidone, a derivative of polyvinylpyrrolidone or a combination thereof. The inorganic particle is a metal oxide composed of a first metal MA, a doping metal MB and oxygen. The inorganic particle makes up 62.5-99.9 wt. % of the nanocomposite powder.

    摘要： The present invention relates to a modified cellulosic fiber that comprises anionic moieties in an amount of more than 0.25 mol/kg of dry fiber and has applied theron a polymeric modifying agent in an amount of from 0.5 wt. % to 5.0 wt. %, based on dry fiber, the polymeric modifying agent comprising cationic moieties with a charge of at least 1.5 meq per gram of polymer and the molar ratio of anionic moieties to cationic moieties contained in the fiber is in the range of from 1:1 to 25:1. The fiber according to the present invention is characterized in that the anionic moieties are incorporated in the fiber and are from carboxymethylcellulose, and that the polymeric modifying agent comprising cationic moieties is selected from the group consisting of polydiallyldimethylammonium chloride (poly-DADMAC), poly(acrylamide-co-diallyldimethylammonium chloride) (PAM-DADMAC) and mixtures thereof. The invention furthermore relates to a nonwoven product or fabric comprising the modified cellulosic fiber. (FIG. 1)
