摘要： A PTFE fiber with a low density and having a network structure that allows effective performances to be given to its finished articles and a method for manufacturing the PTFE fiber are provided. The PTFE fiber is a filament obtained by giving a heat treatment to a biaxially stretched polytetrafluoroethylene (PTFE) film, followed by slitting partially in a lengthwise direction of the film. The filament includes a network structured fiber in which single fibers are opened partially in the width direction, and the filament is an aggregate of the single fibers. This fiber is manufactured as the filament by feeding a biaxially stretched PTFE film to a revolving pin roll with needles implanted thereon, the needles being arranged so that a plurality of rows run obliquely along a circumferential direction at substantially regular intervals, and slitting the film partially in a lengthwise direction. This PTFE filament may be cut into short fibers with a cutter. The short fibers include a branch structure.

摘要： To provide a method of producing a uniaxially stretched polytetrafluoroethylene gasket tape, which comprises: (1) a step for preparing a paste comprising a mixture of a polytetrafluoroethylene powder obtained by emulsion polymerization and an extrusion aid, (2) a step for extruding the paste by means of an extruder equipped with a die which has plural separators inside an orifice thereof having a rectangular cross section, (3) a step for rolling, in the extruding direction, an extrudate having slit lines to give a rolled polytetrafluoroethylene sheet, (4) a step for uniaxially stretching the rolled sheet in the rolling direction after removing the extrusion aid from the rolled sheet, and (5) a step for heat-treating the obtained uniaxially stretched polytetrafluoroethylene sheet. The die of the extruder has plural sheet-like separators in the orifice thereof having a rectangular cross section. The separators are mounted so that free ends thereof are located at a point exceeding a center point of a long side of the orifice, and function to provide slit lines inside the extrudate in parallel with the long side of the orifice. The high performance inexpensive PTFE gasket tape is produced by the uniaxially stretching method and has properties equal to those of biaxially stretched PTFE gasket tape.
