Abstract:
Wallcoverings which include a nonwoven synthetic substrate and a water-based ground coating which is applied thereto. The ground coating includes emulsion polymer pigment binders and a mineral pigment composition. The ground coating provides the nonwoven substrate with superior printing and durability properties, enabling the production of wallcoverings which may be printed with a decorative design. The wallcoverings are desirable for environmental, health, and safety reasons.
Abstract:
The invention relates to a flexible scrubbing material that combines at least two discrete components. One component is a continuous flexible substrate. A second component is a discontinuous abrasive layer affixed to the flexible substrate. The abrasive layer is a set of plates formed from a material different than the continuous flexible substrate. One or two flexible substrates with affixed plates can be combined with an intermediate layer such as sponge or terry cloth. The gaps between plates are relatively large and are generally larger than one-third the largest plate dimension. The flexible substrate can be tightly woven fabric that can be printed with visually attractive colors, patterns and images. The plate material is a printable material that subsequently solidifies, such as epoxy. The inventions include associated methods of use and manufacture.
Abstract:
The floor covering includes multiple layers including a non-woven base layer, a VAE precoat applied to the non-woven woven base layer and overlaid by a first PVC layer. A fiberglass mat is applied over the first PVC layer and a second PVC layer is applied over the mat. A woven PVC layer is laminated by heat and pressure to the underlying second PVC layer. The woven PVC layer comprises monofilament or multifilament cores, preferably but not limited to, polyester filaments overlaid by a PVC coating.
Abstract:
Reactive geocomposite mats, and their method of manufacture, for treating contaminants in soil or water that allow the passage of essentially non-contaminated water therethrough. The geocomposite mat includes a pre-formed woven or non-woven geotextile, having a thickness of about 6 mm to about 200 mm, and having, a porosity sufficient to receive a powdered or granular contaminant-reactive material, contaminant-sorptive material, or a contaminant-neutralizing material (hereinafter collectively referred to as “contaminant-reactant material” or “contaminant-reactive material”) throughout its thickness, or in any portion of the thickness across its entire major surface(s). The powdered or granular contaminant-reactive material is disposed within the pores of the previously formed, high loft geotextile mat to surround the fibers, e.g., by vacuum or vibrating the high loft mat while in contact with the contaminant-reactive material to allow the powdered or granular contaminant-reactive material to flow by gravity into the pores of the previously formed geotextile and vibrational forces. Liquid-permeable cover sheets are adhered to the upper and lower major surfaces of the filled geotextile to prevent the powdered or granular material from escaping from the geotextile during transportation and installation.
Abstract:
An upper surface layer 2 and a nonwoven fabric sound absorption layer 3 are integrally secured via an air permeable adhesive resin layer 4 formed by melting thermoplastic resin powder, and the air permeability of the thickness direction of the entire carpet 1 falls within the range of 1 to 50 cm3/cm2·second. This effectively absorbs noise from the upper side entering via a roof, doors and windows as well as noise from the lower side. The carpet can be manufactured by scattering thermoplastic resin powder on an upper surface member, heating the thermoplastic resin powder into melted thermoplastic resin, placing a nonwoven fabric on the upper surface member via the melted thermoplastic resin, and pressing the nonwoven fabric and the upper surface member in a laminated state. It is preferable that powder of particle size of 90 to 10,000 μm is scattered in the amount of 5 to 500 g/m2.
Abstract:
A nonwoven fabric is provided for a primary carpet backing comprising a bicomponent filament of polymeric core/sheath-type, the polymeric core component of which has a higher melting point than the polymeric sheath component, said bicomponent filaments are bonded together by the application of heat to form said fabric, characterized in that the polymeric sheath component is selected from the group containing polypropylene and copolymers comprising polypropylene and/or blends thereof. The invention is further directed to a process of manufacturing such nonwoven fabrics and to articles, such as car carpets, comprising them.
Abstract:
A backing or an intermediate layer for a surface covering is described which comprises a fused recycled material, wherein the material comprises a thermoplastic material, for instance, a vinyl material from a vinyl backed carpet or vinyl backed carpet manufacturing waste or both. Surface coverings containing the backing or intermediate layer of the present invention are also described as well as methods of making the backing or intermediate layer and methods of making the surface coverings containing the backing or intermediate layer of the present invention.
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 310null 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 process for forming a carpet, and the carpet formed thereby are provided. The process includes forming a thread comprising low melt fiber and high melt fiber. The thread is then heated above a temperature sufficient to melt the low melt fiber. The thread is tufted in a carpet backing to form a tufted carpet. The tufted carpet is then printed or dyed with an image. A process for forming a low melt content yarn and the yarn formed thereby are provided. It is preferred that the carpet and low melt content yarn be adapted to printing or dyeing.
Abstract:
To improve the liquid barrier properties of a carpet, a repellency compound, such as a fluorochemical, is applied to the backstitch side or underside of the primary backing layer of a carpet.
