Abstract:
Seam strips are provided in a textile covering for a floor, wall or ceiling which are exposed and afford an aesthetic surface treatment. The seam strips comprise inverted T-shaped strips with an upstanding web terminating in a margin short of the pile height and a pair of flanges projecting laterally from each of the lower opposite sides of the web. The flanges have holes for securing, by way of screws or nails, the strips to the underlying floor, wall or ceiling. The adjacent edges of the textile covering are secured to the upper surfaces of the flanges. The textile coverings preferably have the backstitches of tufts and portions of the primary backing forming an exposed surface which, together with the exposed margin of the strips, form an aesthetically pleasing surface treatment.
Abstract:
The invention relates to an acarcid-resistant carpet wherein an acaracidal compound is fixed at or near the base of the carpet tufts over which an adhesive layer is applied to the carpet tufts into a primary backing material. The invention further relates to methods of making such carpet.
Abstract:
A coated woven textile fabric is disclosed which is formed of synthetic yarns of more than one denier preferably synthetic filamentary yarns of differing deniers. A polymeric coating such as polyurethane is layered on at least one side thereof, but may also be provided on both sides. The combination of yarns of different deniers provides a superior adhesion surface for the polymeric coating. The yarns and the polymeric coating are preselected respectively in deniers and thickness so as to render the fabric substantially impermeable to fluid under pressure, while maintaining superb packageability and antiblocking properties for use in vehicle occupant restraint systems. A flexible lightweight air bag for receiving and containing fluid under pressure for use in a vehicle air restraint system is also disclosed, incorporating the woven textile fabric of the invention.
Abstract:
The invention is directed to fabric-based inserts and layers for use with tires in order to provide an improved level of puncture resistance to the tire. Disclosed embodiments of the invention include tire anti-puncture layers including puncture-resistant layers that comprise a single or multiple layers of fabric. Preferably, for low cost and low abrasion, the puncture-resistant layers comprise fibers having a tensile strength or tenacity of less than about 15 g/denier. In some preferred constructions, especially where the puncture-resistant layer comprises a single layer of fabric, the puncture-resistant layer comprises a high cover factor, tightly woven fabric, for example having a round packed cover factor of at least about 40% of full in the warp direction and at least about 65% of full in the fill direction. In other embodiments, especially where the puncture-resistant layer comprises multiple layers of fabric, lower cover, less tightly woven woven fabrics can be used, or, alternatively, non-woven fabrics such as knitted or felted fabrics (felts) can be used. Some such preferred, less tightly-woven fabrics are woven from untwisted yarns, enabling the fibers or filaments comprising the yarns to spread out into a tape-like configuration under compression, thereby increasing the effective cover factor and level of puncture resistance over that predicted from the round packed cover factor. A nulltaped fiber densitynull calculation is presented for predicting the effective cover factor of such taped-out woven fabrics, and certain preferred embodiments of such fabrics have a taped fiber density of at least about 80% of full in at least one of the warp and fill directions. In some embodiments, the puncture-resistant layer, or one or more layers of fabric comprising the layer, are coated with polymeric coatings to increase the level of puncture resistance. In some embodiments, the tire anti-puncture device is configured as a separable strip that can be placed within a tire to act as a liner. In other embodiments, the puncture-resistant device is incorporated within the cross-section of the tire body itself. While the tire anti-puncture device in some embodiments comprises just the puncture-resistant layer, in other embodiments, one or more low abrasion layers can be added to isolate and protect the tire and/or inner tube, if present, from the puncture-resistant layer. Such law abrasion layer(s) are particularly useful for embodiments involving puncture-resistant layers coated with polymeric coatings containing abrasive fillers, which can serve to increase puncture resistance but tent also to increase abrasiveness of the puncture-resistant layer.
Abstract:
Polymeric carpet and a method of making and recycling such carpet, the carpet having fibers, backing and extruded adhesive all of completely recyclable materials, the recycling being accomplished in one melting step, without a separation step.
Abstract:
A carpet in tile or roll form is produced using an open mesh reinforced foam layer with foam nodules. The carpet is produced having a primary backing through which carpet fiber bundles are tufted and a precoat layer which locks the tufts in place to prevent easy extraction of the fibers so that a tufted face and a relatively smooth back face are provided. The foam layer with foam nodules is brought into intimate contact with the relatively smooth back face, and is substantially permanently adhered to it producing a carpet tile or roll that is substantially prevented from curling or doming (or they are significantly reduced) and may be installed without adhesive if desired. Adhering may be practiced by using a non-fused adhesive formulation which is subsequently fused at a low temperature (about 310.degree. F. or less), or by forcing the foam layer with foam nodules into contact with the carpet back while the hot melt backing is still in a fluid form, or by use of a thermoplastic layer between the carpet and foam sheet.
Abstract:
A composite floor covering having an upper layer of a decorative fabric, a dimensionally stabilizing intermediate layer, and an optional lower cushioning layer has at least the upper surface of the decorative fabric coated with a protective polymeric coating in a manner such that the hand of the decorative fabric layer is substantially retained. The materials of the fabric layer, stabilizing layer, and cushioning layer (if provided) as well as the form of attachment therebetween, cooperate to render the floor covering substantially impervious to liquid.
Abstract:
A mat for removing dirts or dusts comprises a cushioning material made of a plurality of curled elastomeric filaments and a collector sheet of electret laying under the cushioning material. The filaments are formed of a compound of synthetic resinous material and a powdered electrical conductive material, and entangled with each other to provide a plurality of through holes or voids extending vertically through the cushioning material.
Abstract:
A carpet underlay comprising a fibrous non-woven substrate composed of natural or synthetic fibers having in or on it a repellent finish which makes said substrate substantially impervious to liquids.
Abstract:
A tufted carpet comprising a base and a plurality of tufts. Each of the tufts have a looped portion on an underside of the base. The looped portions are fused to the underside of the base and to adjacent looped portions using heat and pressure, thereby forming a homogeneous layer of the looped portions on the underside of the base.
