POLYTETRAFLUORETHYLENFASER, BAUMWOLLARTIGES, DIESE FASER ENTHALTENDES MATERIAL, UND VERFAHREN ZU DEREN HERSTELLUNG

摘要

A cottony polytetrafluoroethylene material is obtained by breaking a monoaxially stretched polytetrafluoroethylene molding by a mechanical force. This material contains 5-150 mm long fibers having branches and crimps and a cross section with an indefinite shape. It can be interlaced so well that it can readily provide nonwoven fabric. <IMAGE>
