摘要:
In accordance with the invention, a laminate of two or more layers and the method of making it is provided. The laminate includes at least one organic synthetic filament non-woven layer, and at least one woven web or scrim of glass fibers pre-consolidated by a binding agent. The polyester non-wovens and the woven webs or scrims are bound by needling such that a part of the (e.g., polyester) filaments penetrate through the laminate and emerge at the lower surface of the laminate and lie adjacent thereto The formed laminate is subjected to a final consolidation by an acrylate or a styrene binder.

The present invention provides non-woven laminate that is not subjected to final consolidation by a binder and the production thereof. The laminate includes at least one non-woven mat containing glass staple fibers pre-consolidated with a resin, and at least one non-woven layer of synthetic fibers. The synthetic non-woven layers and the pre-consolidated non-woven mat of glass fibers are bounded together by needling such that a portion of the fibers of the upper synthetic non-woven layer passes through the non-woven mat of glass fibers possibly through the underlying synthetic non-woven layer. The synthetic fibers are heat shrunken and the laminate is binder free.

A method of bonding an unsintered unexpanded PTFE feed film to a flexible PTFE coated substrate comprises providing a three roll calender comprising a metal surfaced roll coacting with two filled rolls to define first and second nips. The PTFE feed film is calendered in the first nip, with the thus calendered PTFE film remaining supported on the metal surfaced roll for transport to and through the second nip. The PTFE coated substrate is directed through the second nip for calendering with and bonding to the calendered PTFE film to thereby produce a laminated composite.

Disposable polymeric container covers, methods of manufacturing the same, and machines for manufacturing the same are disclosed wherein the cover may include a polymer film adapted to enclose a bowl or the like, and an elastic film proximate thereto adapted to seal the cover against the bowl. The elastic film may be provided as an annular member completely surrounding the bowl, or in segments around an otherwise non-elastic ring. The method may include co-extruding the elastic with the non-elastic polymer, or stamping the elastic and non-elastic polymers as separate pieces and then heat sealing them together.

A method of forming a laminate of at least two layers including at least one aramid paper with at least one layer of polymer by calendering opposing surfaces of the aramid paper at different temperatures prior to laminate formation.
摘要:
The present invention provides wall and floor coverings based on a carrier coated with one or more layers. The carrier includes a fiberglass containing mat consolidated with a binder, a non-woven made of organic synthetic fibers bonded with the fiberglass containing mat by needling. Part of the organic fibers penetrate through the fiberglass mat, and one or more layers coated on a glass fiber side of said carrier, opposite the non-woven synthetic mat.
