Abstract:
Disclosed is a precoat resin dispersion having a solids content from about 63% to about 69% comprising (1) at least one resin having a Ring and Ball softening point from about 60.degree. C. to about 100.degree. C. in an aqueous dispersion having a solids content from about 53% to about 58%; (2) at least one water-soluble polymer; (3) at least one cationic resin; and (4) water. The precoat resin dispersion is useful in the manufacture of tufted carpets, especially carpets manufactured with carboxylated latices as a backcoat.
Abstract:
Polymeric blends comprising a rubber latex and large particle size solid polyvinyl chloride resin provide good tuft lock in tufted carpets and enhance flame retardancy of same. The blend is applied to the carpet and dried at an elevated temperature below the flux temperature of the polyvinyl chloride resin.
Abstract:
Wet steam or hot water treatment of a secondary backing just before application to an aqueous adhesive coated back of a carpet or rug such as a tufted carpet containing a primary backing provides on drying and curing of the laminate an increase in many instances in the dry and wet strength of the secondary backing to the primary backing and some reduction in the time of drying or curing of the adhesive to bond the laminate together.
Abstract:
The present invention relates to a flexible sealing membrane that is particularly useful for covering roofs. The flexible sealing membrane is usable for sealing substantially planar surfaces such as roofs or the like, said membrane being essentially water- and steam-tight, characterized in that said membrane does not contain any bitumen or bitumen derivative and also characterized in that said membrane is essentially formed of at least one thermoplastic (co)polyurethane or thermoplastic (co)polyamide, thus ensuring the essentials of said sealing functions, said thermoplastic (co)polyurethane(s) or thermoplastic (co)polyamide(s) each containing at least one natural monomer that is integrated into the (co)polymer during the polymerization(s) thereof.
Abstract:
A lightweight, high-strength composite fabric (110) suitable for use in a carpet backing, roofing and membranes and other products which employ rugged fabrics. The composite fabric (110) comprises a layer of nonwoven material (116) disposed between a layer of low shrinkage warp strands (112) and a layer of low shrinkage weft strands (114). The layers are stitched or knitted together and the resultant fabric (110) may be coated with a resin or sizing agent (122) to prevent slippage between the several layers of the fabric (110) and impart a measure of stiffness to the fabric (110). The fabric may be manufactured in sheet or, more preferably, roll form and may be coated with materials suitable for desired end applications, e.g., bituminous material whereby the fabric (110) may function as a ready-to-use roofing membrane or other high-strength fabric product.
Abstract:
The invention is directed to carpet coating compositions which utilize an emulsion binder which is prepared by emulsion polymerization of ethylene, a vinyl ester monomer having a Tg of between about 20°C and about 45°C, and an essentially non-reactive monomer having a Tg of less than 10°C, and to carpet products prepared with the carpet coating compositions.
Abstract:
Carpet coating compositions are disclosed which comprise 40 to 80 percent by weight filler and 20 to 60 percent by weight of a latex binder, the binder comprising an emulsion polymer of a) 40 to 80% by weight of a vinyl ester of an alkanoic acid, the acid having from 1 to 13 carbon atoms; b) 5 to 25% by weight of a copolymerizable comonomer having a Tg of at least 50°C; and; c) 10 to 30% ethylene.
Abstract:
The invention relates to a canvas to be painted, consisting of a fabric comprising plant fibres, especially linen, jute, ramie and/or sisal, said fabric also being coated with a size.
