  • Patent number: 5589245
    Abstract: The textile spacer material is a material for replacing foamed substances; it consists of two knitted or woven covering layers that are connected by a pile thread structure. The pile thread structure produces the compressibility known from flexible foams and the large air fraction. The elasticity can be determined by the length and density of the pile threads and the material used. When recyclable materials are used, an environmentally compatible foam substitute can be obtained. Moreover, the textile spacer material can also assume chemical or physical properties through the use of treated starting material or a treatment during or after production and thus be used as a filter or catalyst material, for example.

  • Patent number: 5445860
    Abstract: A method for making tufted carpet, as well as the tufted carpet made by this method, are provided. Pile yarn fibers are tufted into a tufting backing, which is composed of a primary backing, a secondary backing, and an elastomer sandwiched between the primary and secondary backings. In another embodiment, the tufting backing comprises a primary backing and an elastomer applied to the primary backing, but does not include a secondary backing. In a preferred embodiment, the elastomer is applied to the primary backing in a non-contiguous form whereby voids are provided within the arrangement for the tufting backing to be tufted without the primary backing fibers being immobilized. After the pile yarn fibers are tufted into the tufting backing, the elastomer is heated such that it softens, allowing the elastomer to flow in and around the pile yarn fibers. The elastomer may then be cooled, thereby hardening the elastomer and bonding the pile yarn fibers to the primary backing.

The contamination of the film by the thermobleeding of the dye is prevented by using a particular dye. The generation of static marks is also prevented by treating the light-shielding cloth comprising synthetic fiber with a special antistatic agent or treatment.

  • Patent number: 5227409
    Abstract: A polyurethane adhesive is prepared from a reaction mixture containing small amounts of chain extender material and a high equivalent weight of a polyol and a monoalcohol. An article adhered to a substrate using this adhesive is firmly affixed to the substrate, yet can be removed without leaving residual adhesive on the substrate. In addition, this adhesive can be washed and reused if desired.

  • Patent number: 5227214
    Abstract: A cleated dust control mat having a plurality of rows of elliptical cleats located at an angle to the border of the mat with the cleats in each row being parallel to the other cleats in the row and being substantially perpendicular to the cleats in the next adjacent rows of cleats. A second set of small circular cleats is located between the elliptical cleats in each row equally spaced from adjacent elliptical cleats in each row.

  • Patent number: 5217783
    Abstract: The specification discloses a two-sided carpet construction and a method for the continuous manufacture thereof. The carpet manufacturing process begins by tufting a carpet yarn into a scrim layer. The process continues up to the point where the bonding material is applied to the carpet scrim to lock the tufts of the carpet fiber in place. In the process disclosed herein, immediately after the bonding material is applied, a piece of carpet material, by which may be similar to the piece just described, or which may be different in color or construction from that just described, is continuously applied in 180.degree. opposed relationship on the top of the bonding material just applied. The carpet construction thus formed is then passed through pressure applying means to firmly force the bonding material into the carpet tufts and carpet scrim to form a continuous piece of two-sided carpet material having approximately half the weight of bonding materials of previous constructions.

  • Patent number: 5204155
    Abstract: A floor covering, such as a carpet or carpet tile, which comprises a primary backing sheet having a fibrous face wear surface and back surface and first and second backing layers and with a low density, resilient, non-elastomeric, closed cell polymeric foam layer, such as a thermoset, cross-linked polyethylene foam layer, positioned between and bonded to the first and second backing layers, optionally with a secondary backing layer bonded to the secondary bitumen backing layer. A method of producing a floor covering, such as a carpet tile, which comprises providing a primary backing sheet having a fibrous face wear surface and a back surface and bonding a first bitumen backing layer onto the primary backing sheet, bonding a low density, thermoset, polymeric foam layer to the first bitumen backing layer through a glass tissue to protect the polymeric foam layer and stabilize the composite, and bonding a second bitumen backing layer onto the polymeric foam layer.

  • Patent number: 5198278
    Abstract: In a mat composed of a base cloth, a pile tufted thereto, and a rubber backing applied to the non-pile surface of the base cloth, a cotton-like layer composed of a woven cloth of a polyester textured yarn non-adherent to the rubber and a filament or staple which layer is needle-punched is used. In this mat, weakly adherent regions at which the woven cloth and the rubber portion contact each other and strong adhesive regions at which the cotton-like layer and the rubber portion content each other are formed in dots in a large distribution. Waving deformation during repeated use is prevented.
