Abstract: Process for preparing an industrial polyester multifilament yarn with high modulus and low shrinkage, in which polyethylene terephthalate polyester is wound at 2000 m/min or more to produce undrawn yarns with an intrinsic viscosity of 0.88 or higher and a density of 1.338 to 1.365 g/cm3, an oiling agent is provided to undrawn yarns, the resulting undrawn yarns are wound, drawn through three stages, heat set, relaxed, and wound again. The polyethylene terephthalate polyester yarn is produced by drawing undrawn yarns at a glass transition temperature (Tg, about 80° C.) or lower through three stages under conditions that a draw ratio of the 1st stage is greater than a draw ratio of the 2nd stage or a draw ratio of the 3rd stage and the draw ratio of the 3rd stage is greater than the draw ratio of the 2nd stage.

Abstract: Processes for coating sewing thread using a radiation curable composition and the resultant coated sewing thread. Sewing thread is coated with a radiation curable composition, which exhibits a self sustaining cure after exposure to radiation. The composition is applied using contact coating techniques to coat and impregnate the thread with resin. The coated thread is then exposed to radiation to cure the coating. Because the cure is self sustaining, the composition more fully and completely reacts to form a coating with increased durability and reduced susceptibility to stripping or flaking during use in demanding industrial applications.

Abstract: The present invention provides a fiber reinforced polypropylene-based composite material comprising reinforcing fibers and a matrix resin, wherein the reinforcing fibers and the matrix resin are made of different polypropylene-based resins and wherein a melting point, Tm(F), of the polypropylene-based resin which is the material forming the reinforcing fibers and a melting point, Tm(M), of the polypropylene-based resin which is the matrix resin satisfy Tm(F)−Tm(M)>10° C. Since the fiber reinforced polypropylene-based composite material of the present invention contains reinforcing fibers and a matrix resin both of which are made of polypropylene-based resins, adhesiveness of the reinforcing fibers and the matrix resin is excellent and therefore the composite material exhibits excellent mechanical strength.
