Abstract

1394460 Non-woven fabrics RHONE-POULENC SA 15 Dec 1972 [17 Dec 1971] 58047/ 72 Headings D1R and D2B A non-woven fabric comprises a web of either non-fusible fibres or fibres having a softening point or melting point above 180‹C bonded together by a polyamide-imide in an amount from 3 to 150% by wt. based on the dry wt. of the fibres. The polyamide-imide may comprise a plurality of units of the formula: in which Q represents a divalent radical containing at least one benzene ring and R represents a trivalent aromatic radical. The fibres may be inorganic e.g. glass, carbon, boron, asbestos, metal e.g. copper, steel, or fibres of aluminium oxide and of zirconium oxide, or organic polymeric e.g. polyesters, polyacrylonitrile, polytetrafluoroethylene, copolymers of tetrafluoroethylene and hexafluoropropylene, polyamides, or polyamide-imides. The fabric may be made by forming a dry web of fibres, contacting the web with organic solution of the polyamide-imide, and drying the treated web. The web may be formed by a dry technique e.g. by superposing layers of carded parallel fibres with binder in between the layers, or by blowing the fibres against a screen using an air jet, or by spin bonding. Such dry-formed webs may be mechanically treated e.g. needled punched. Alternatively, the web may be formed by a papermaking method. Binders e.g. polyvinyl alcohol, may be incorporated in the aqueous dispersion of fibres before web-formation. The non-woven fabric may be used in the manufacture of filters, cores for insulating linings, arid catalyst supports.
