ABSTRACT Non-woven fabrics produced from spunbonded web of the thermally bonded type suitable for use in folding window blinds are disclosed. To provide an opaque fabric with a weave-like finish a metalized blackout film and the spunbonded web substrate are laminated together while simultaneously embossing the substrate. Non-opaque fabrics may be made by using a film without metalization. Binder material is added to provide corrosion protection for the metalized film and additional bonding to the substrate . Difficulties in embossing this type of web are overcome by using steel embossing rollers and narrow widths of web. Using this basic process opaque fabrics may be made without embossing by creating a temporary bond between the layers with the surface tension of water, or non-opaque fabric made by not adding any film in the embossing step.
