Abstract: A rubber-reinforcing polyester fiber composed of a polyester prepared by using 30 to 150 ppm as antimony of an antimony compound and 5 to 60 ppm as germanium of a germanium compound as the polymerization catalyst. The fiber is characterized in that the terminal carboxyl group content is not larger than 25 eq/ton, diethylene glycol content (DEG) is not larger than 1.3% by weight, the intrinsic viscosity (IV) is at least 0.85, the sum (S) of the intermediate elongation and the dry heat shrinkage is lower than 8%, the product between strength and elongation (T~E) is at least (2S + 5), and the terminal modulus (TM) is not higher than 40 g/d. The polyester fiber is used as a rubber reinforcement.

Abstract: Disclosed is a biodegradable oriented film of a plasticizer-containing biodegradable resin, of which the both surfaces are coated with at least one thin layer and of which the loop stiffness change ( DELTA R) after heat treatment at 130 DEG C for 30 minutes is at most 20 %. This is favorable for wrapping films.

Abstract: A biaxially oriented polypropylene film exhibiting a high rigidity in the machine direction can be produced according to a general lengthwise-widthwise sequential biaxial stretching process either by specifying the additive contained in the film, the melt-tensile strength (MS) and melt flow rate (MFR) of the polypropylene as determined at 230 °C, or the Trouton ratio of the polypropylene or by making specified longitudinal fibrils present in the film.
