Abstract:
A carpet tile of improved dimensional stability having a hot melt composition backing layer and which has a secondary backing of a glass fiber tissue sheet material directly adjacent to a non-woven fibrous sheet material, such as a polypropylene sheet material. The backing layer penetrates the glass fiber tissue sheet material and partially penetrates and bonds the fibrous sheet material which forms the exterior surface of the secondary backing. The method of producing the carpet tile includes forcing the liquid, hot melt composition into the secondary backing sheet employing a roll-over-roll applicator.
Abstract:
A backing layer and a substrate layer, particularly of fabric-backed tufted carpeting, are bonded together using discrete areas of adhesive applied to one side of the backing layer. The adhesive is applied using a perforated roller (3) with an internal abutment such as a second roller (4). The adhesive material (6) is fed to the inside of the perforated roller (3) and is forced through the perforations with the internal roller (4).
Abstract:
A broadloom carpet is featured that can be laid similar to modular carpet tiles, and which can be cut or severed to remove damaged portions or to gain access to the floor below the carpet. The carpet is uniquely characterized by its ability to prevent fraying and/or warping of severed flaps.
Abstract:
A warp resistant tile and method for preparation thereof in which a primary facing layer is secured to a tile backing layer which comprises a laminate having(A) a characterizing layer of predetermined weight, bulk, and strength, this layer and being complementary to the primary facing, and to(B) a thin flexible base layer.
Abstract:
Lamination of a tufted, primary carpet backing to a secondary backing is conducted using a composite hot melt adhesive in sheet form. The composite adhesive overcomes the unfavorable temperature-viscosity gradient within the carpet structure during the lamination process, yielding tufted pile carpets with good tuft encapsulation, tuft bind strength and delamination strength. Also disclosed are hot melt adhesive compositions suitable for use in sheet form in such a process.
Abstract:
A carpet tile and method of production wherein the carpet tile comprises a carpet tile having a fibrous face, such as a tufted face, and a fibrous back surface secured to a primary backing and comprising three separate hot melt coating composition layers and a secondary backing on the back surface of the carpet tile. The carpet tile is produced by coating a thick backing layer of a rubber-modified bitumen coating composition onto a secondary backing sheet material and separately coating a first precoat layer comprising a hot melt petroleum resin or bitumen and a second layer comprising a hot melt bitumen composition containing a flexible vinyl adhesive resin, like ethylene vinyl acetate, onto a fibrous back surface of a carpet material having a primary backing sheet containing a fibrous face wear surface and laminating the surface of the second layer to the surface of the backing layer to provide a carpet tile having dimensional stability, good lay flat characteristics and capable of production by an in-line production method.
Abstract:
A process is provided for making a water-impermeable, vapor-permeable fabric. A lightweight continuous coating of polypropylene resin is applied to the surface of a fibrous sheet to make the sheet impermeable to water and vapor. Subsequent calendering provides vapor permeability to the sheet while maintaining liquid water impermeability. The resultant product is particularly suited for use as a roofing-tile underlayment or as an air-infiltration barrier.
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:
A felting of synthetic fibers having an embossed pattern that forms depressions in at least one surface of the felting is disclosed. The surface of the felting with depressions contains, in at least the area of the depressions, a layer of small hollow spheres that are bonded to one another and to the felting by means of a binding agent. The layer of hollow spheres fills up, at least partially, the depressions in the surface of the felting produced by embossing. This reinforces and strengthens the thinner areas of felting in the vicinity of these depressions. When the reinforced felting is applied to a shoe upper, for example, the resulting upper has improved stiffness and strength. Furthermore, the excessive penetration of adhesive into the felting, which can cause a spotty or uneven appearance of the reinforced upper, is prevented. Resistance to splitting and separating is likewise improved.
Abstract:
Multicolored pile materials, and particularly pile carpets, comprising a fabricated backing and a fabricated pile face having: (1) upper pile face portions which have a predetermined color; and (2) lower pile face portions which have a color which is different and darker than the predetermined color of the upper pile face portions, whereby unusual multicolored effects are obtained; and, more specifically, multicolored pile fabrics, and particularly pile carpets, comprising a fabricated backing and a fabricated pile face having: (1) upper pile face portions which are substantially white in color; and (2) lower pile face portions which have a color which is different and darker than white, whereby unusual multicolored, frosted effects are obtained. Processes for making such multicolored or frosted pile materials are also included.
