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： A polytetrafluoroethylene (PTFE) fiber includes a filament obtained by partially slitting an oriented PTFE film in a lengthwise direction of the film. Emboss processing is conducted linearly along the lengthwise direction of the film and like a zigzag shape or a convexo-concave shape in a width direction of the film, followed by slitting, whereby the filament includes a network structure in which single fibrils that are opened partially are arranged regularly. A PTFE short fiber is obtained by cutting the above filament and includes a branch structure. Thereby, a PTFE fiber with a small average fineness of single fibrils, a uniform fineness and a single-peak distribution with the peak at a center of fineness and with a high production yield and uniform and stable branch structure can be provided and a method for manufacturing the PTFE fiber can be provided.
