Abstract: Fibers and filaments of an ultra-high-molecular-weight polyolefin that have a void volume greater than about 20% and are wettable. Wettability is imparted to the fibers and filaments by incorporating a filler into the composition that is hydroscopic, has a particle size less than about 10 microns in diameter and a surface area greater than about 30 square meters per gram. The preferred fillers are those that contain surface silanol groups. The fibers and filaments are formed by the process of preparing a mixture of an ultra-high-molecular-weight polyolefin, filler and plasticizer, metering the mixture to an extruder, heating and kneading the blend in the extruder, conveying the extrudate to a fiber or filament forming type die, expressing the extrudate through the die openings to form fibers or filaments, and extracting at least a portion of the extractable plasticizer to provide the desired porosity.

Abstract: A container body for a photographic film cartridge which comprises propylene-ethylene random copolymer resin composed of 96 to 98.5 wt. % of propylene units and 1.5 to 4 wt. % of ethylene units having a melt flow rate of 10 to 70 g/10 minutes and a molecular weight distribution of 2.5 to 5.5, Rockwell Hardness R of more than 80, and an organic nucleating agent. In the container body for a photographic film cartridge of the invention, breakage and cracking do not occur by the improvement in dropping strength. The white powder caused by the friction with the film cartridge packaged therein is prevented by the improvement of Rockwell hardness and wear resistance. The white powder caused by the sublimation or bleeding out of the organic nucleating agent is also prevented by the resin composition.
