摘要： Improved meltspinning productivity is achieved by employing polyolefin resins having key molecular weight distribution and rheological property parameters within predetermined ranges. These parameters include the molecular weight distribution breadth parameter, M.sub.z /M.sub.n ; and rheological property parameters of flow rate ratio, I.sub.10 /I.sub.2, and the power law index, n, of the regression analysis viscosity equation. These parameters additionally include one or both of the z-average molecular weight, M.sub.z, of the resin, or the second order constant, b.sub.2, of the regression analysis viscosity equation, and unless both of the latter two parameters are met, the parameters further include the die swell and the spinnability factor (determined from the relationship between die swell and MFR) of the resin.

摘要： Fibers of linear polyethylene or polypropylene are solution spun, cooled, dried in hot air and hot drawn. Drying and hot drawing are carried out by passing a moving filament of the wet polymer through a hot air dryer having an air temperature of at least 55.degree. C., preferably at least 60.degree. C., then heating and hot drawing a moving filament of the dried fiber. Optional steps include wet drawing the fiber prior to drying, and solvent exchange of the original solvent, e.g. decalin, for a more volatile solvent.

摘要： There is disclosed a radiation stabilized fabric of propylene polymer or copolymer of propylene which has improved odor characteristics. Radiation stabilization results from adding by weight 0.25 to 2.0 percent of an acetylated hindered amine light stabilizer known in the art as Cyasorb UV-3668 or by adding by weight 0.25 to 2.0 percent of an oligomeric, hindered amine substituted siloxane such as polymethyl propyl 3-oxy [4- (2, 2, 6, 6-tetramethyl) piperdinyl] siloxane.

摘要： A polyolefin BMF web made from a mixture of polypropylene and surfactant can have high wet strength when a) the surfactant is nonionic and b) the surfactant is mixed with the polypropylene at a static mixer that interconnects the extruder and the BMF die. By so postponing the addition of the surfactant, it is protected from both the exceedingly high temperatures of the extruder and from the high shearing forces within the extruder. The surfactant also is heated to high temperatures for a much shorter time than if it were premixed with the polypropylene.
