Textile laminates

Verbunde mit textilem Charakter mit hoher Wasserdampfdurchlässigkeit und hoher Dichtigkeit gegenüber Wasser bestehen aus textilen Flächengebilden, Folien- und/oder Extrusionsbeschichtungen aus modifizierten Polypropylenen und nichtmodifizierten Polypropylenen und gegebenenfalls einer Haftvermittlerzwischenschicht zwischen textilem Flächengebilde und Folien- und/oder Extrusionsbeschichtung. Die Herstellung der Verbunde mit textilem Charakter erfolgt durch Extrusionsbeschichtung oder Folienbeschichtung der textilen Flächengebilde. Einsatzgebiete der Verbunde mit textilem Charakter sind der Hygienebereich, der Bereich Medizin, die Textil- und Bekleidungsindustrie, die Automobilindustrie und das Bauwesen. Textile laminate with a water vapor permeability of more than 1000 (preferably more than 1800) g/m per 24 hours and a water tightness corresponding to a water column of more than 500 mm (preferably more than 750) mm comprises: (A) a sheet of woven, knitted or nonwoven fabric based on polyethylene, polypropylene, polyethylene terephthalate, polyamide, cellulose or cotton; (B) a film or extruded coating with a thickness of 3-200 (preferably 5-70) mu m based on polypropylene and containing 0.01-2.5 wt.% stabilizers, 0.01-1 wt.% processing aids and optionally 0.1-1 wt.% antistatic, 0.2-3 wt.% pigments, 2-20 wt.% flame retardants and/or 0.05-1 wt.% nucleating agents and/or 10-70 (preferably 20-50) wt.% (in)organic fillers and/or reinforcers; and optionally (C) an adhesive layer between (A) and (B), having a thickness of 0.5-20 (preferably 1-10) mu m and comprising a polar olefin polymer and/or an olefin graft copolymer, e.g. a copolymer of ethylene with vinyl acetate or (meth)acrylic acid or polyethylene or polypropylene grafted with an unsaturated carboxylic acid or anhydride. The film or extruded coating is based on either: (1) a polymer blend comprising (a) 1-50 (preferably 5-30) wt.% of a modified propylene polymer with a melt flow index of 0.1-50 (preferably 1-40) g/10 minutes at 230 degrees C and 2.16 kg, where the ratio of the limiting viscosity of the modified polypropylene to that of an unmodified polypropylene with approximately the same molecular weight is 0.2-0.95; and (b) 50-99 (preferably 70-95) wt.% of a polymer selected from (i) propylene homopolymers and/or copolymers (statistical and/or block copolymers) with ethylene and/or 4-18C alpha -olefins, with a propylene content of 80-99.9 wt.%, preferably producing using Ziegler-Natta or metallocene cat
