摘要:
The present invention provides expanded polyolefin resin particles which do not suffer a reduction in foamability during production or a reduction in fusibility during molding and which may be used to produce a molded product that does not generate frictional sound. The expanded polyolefin resin particles are obtained by expanding, by using water and/or an inorganic gas, polyolefin resin particles containing a polyolefin resin (a), a product (b) obtained by heating and kneading a mixture containing certain substances, and a water absorbing substance (c).
摘要:
A polymer fiber sheet exhibits high porosity and good tensile properties in both “wet” and “dry” states. A fiber modifying agent is incorporated into a polymer extrusion and fiber formation process to produce a highly porous polymer fiber sheet that is instantaneously wettable by an aqueous medium. The fiber modifying agent functions as either one or both (1) a plasticizer that reduces the polymer extrudate melt viscosity and allows the formation of fine fibers during processing and (2) a surface modifying agent that promotes the instantaneous and sustainable wettability of individual polymer fibers and a porous fiber sheet formed from them. The polymer fiber sheet maintains its wettability even after repeated washing and drying cycles. The resultant fiber sheet can be densified and embossed to provide a desired thickness and porosity, while at the same time longitudinal ribs with desired pattern can also be formed on the fiber sheet.
