    • 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.
    • 阻燃树脂组合物包含热塑性树脂,阻燃增强纤维和阻燃剂。 阻燃增强纤维包括纤维素纤维,接枝到纤维素纤维表面上的磷化合物和结合到磷化合物上的多胺化合物。 阻燃剂是磷基阻燃剂。 用于生产阻燃树脂组合物的方法包括以下步骤:在纤维素纤维已经用电子束照射之后,通过使乙烯基磷酸酯化合物与纤维素纤维接触,将磷酸乙烯酯化合物接枝到纤维素纤维上,任选地接着电子束 照射; 将多胺化合物结合到接枝到纤维素纤维上的乙烯基磷酸酯化合物中以形成阻燃增强纤维; 研磨阻燃增强纤维; 将热塑性树脂,阻燃增强纤维,含有磷系阻燃剂的成分熔融混炼,造粒。 这可以提供具有足够阻燃性的非卤素阻燃树脂组合物。

    • The invention relates to the textile industry, and specifically to methods for processing bast-fiber materials, for instance the fiber of flax, hemp, jute, nettle, kenaf, and others. The technical result which the present invention aims to achieve consists in: enhancing the quality of a cottonized fiber, when processing bast-fiber materials, by means of high-voltage electric pulse discharges following preliminary biochemical and final minimal mechanical processing; and in enhancing the physical/mechanical and spinning properties thereof, which, overall, allows for an optimized, efficient production process. Said technical result is achieved in that a bast-fiber material processing method includes a technological sequence of processes involving feeding raw material into a bale breaker, which is provided with a decompactor, and into a dosing system, processing using high-voltage electric pulse discharges, rinsing with emulsifying reagents, washing and press-drying in a drum-type installation, decompacting, final drying and light decompacting; the raw material is biochemically treated prior to being fed into high-voltage electric pulse discharge chambers.
