Abstract

1286499 Woven and non-woven fabrics GLASSEIDEN-WERK OSCHATZ VEB 6 Oct 1969 48997/69 Headings D1K and D1R A woven or non-woven fabric, suitable for use as a heat resistant filter material, consists of polyacrylonitrile fibres and glass fibres twisted together so that the glass fibres are wholly covered by the polyacrylonitrile fibres; the heat resistance of the polyacrylonitrile fibres has been increased by heat treatment, e.g. at 250-400‹C.
