Binder for carpet coating compositions
The object of the invention is the use of an aqueous dispersion of a vinylacetate-ethylene-copolymer and of at least one polyethylene imine as a binder in a carpet coating composition for the production of carpets.
Reinforced polymeric nonwoven mat for carpet tiles
A carpet tile includes a textile top member and a carrier mat that is coupled with the textile top member via a thermoplastic material. The textile top member includes carpet yarns and a backing that is coupled with the carpet yarns so that the backing structurally supports the carpet yarns. The carrier mat includes a polymeric material component, a reinforcement, and a binder that is uniformly distributed throughout the polymeric material component and reinforcement component. The polymeric material component includes polymer fibers that are randomly oriented and entangled together. The reinforcement is disposed within the polymeric material component so that the reinforcement is entirely covered and concealed by the entangled polymer fibers to prevent exposure to a user. The reinforcement mechanically reinforces and stabilizes the polymeric material component and carpet tile.

ARTIFICIAL TURF FIELD SYSTEM
An artificial turf field system is provided. The system may include a plurality of synthetic turf strands attached to a backing layer and an infill material positioned between the synthetic turf stands. The infill material may include a plurality of porous particles. A sub-layer may be included beneath the backing layer, and may be formed of a resilient material. A support layer may be included beneath the sub-layer, and may include materials configured for drainage. The porous particles of the infill material may include porous ceramic particles and the sub-layer may include rubber. The porous particles may be at least partially coated, for example, by a polymer coating. The infill material may be free of sand and/or crumb rubber.
CARRIER MATERIAL COMPRISING A FIRST PART OF A FORM-FIT CONNECTION
A carrier material includes at least a first thermoplastic fiber layer and a second thermoplastic fiber layer. At least a part of the first thermoplastic fiber layer and/or the second thermoplastic fiber layer at at least one boundary of the carrier material is removed, to provide a first part of a form-fit connection. The carrier material can be used in bituminous roofing membranes, roofing underlayment sheets, carriers for filter media, primary backings for tufted carpets and (cushion) vinyl floor coverings.
Method to produce a laminated textile product
The present invention pertains to a method to produce a laminated textile product, the product comprising a primary carrier sheet with yarns that form a pile on the front surface thereof, and a secondary carrier sheet adhered to the back surface of the primary carrier sheet, the method comprising providing a lick roller having a mass of molten polymer adhesive at its outer circumference, transporting the primary carrier sheet along the lick roller while its back surface is in contact with the outer circumference of the roller at a contact site, thereby transferring a layer of adhesive to the back surface of the primary carrier sheet, and bringing the secondary sheet in contact with the layer of adhesive to adhere the secondary sheet to the back surface of the primary carrier sheet to produce the laminated textile product, wherein downstream of the contact site between the primary carrier sheet and the lick roller, before the secondary sheet is contacted with the layer of adhesive, cobwebbing of the adhesive between the primary carrier sheet and the lick roller is induced.
Geocomposite covering
A geocomposite covering for placement atop the ground including a lower carrier layer and an intermediate layer of particulate material positioned above the lower carrier layer. A synthetic turf is positioned over the particulate material and is affixed to the lower carrier layer to contain the particulate material between the lower carrier layer and the synthetic turf. The synthetic turf is affixed to the lower carrier layer by one or more of stitches, needle-punched staple fibers, linking fibers, heat bonded fibers, or mechanical fasteners. The particulate material can include clays, cementitious materials, granular material, powder-like material, and the like.
METHOD FOR MANUFACTURING A CARPET OR A RUG AND A CARPET OR RUG OBTAINED THEREBY
Method for manufacturing a carpet or a rug, comprising the following steps: the step (S1-S2) of providing a primary backing (1), being a woven or non-woven layer comprising filaments (2) of polyethyleneterephthalate and copolymer of polyethyleneterephthalate, the coPET having a lower melting temperature than the PET and wherein said PET is available in said primary backing (1) in a higher amount than said coPET; the step of providing a glue layer (11) consisting for 50% or more out of coPET; the step of tufting yarn at least into said primary backing (1); the step of activating said glue layer (11) at least for partially fixing said yarn (12) on said primary backing (1). The invention also concerns carpets (16) and rugs that are obtained or obtainable by means of such method.
CARPET TILE
Mass production of carpet tiles can be enabled by a method for manufacturing a carpet tile by applying an adhesive layer to a carpet tile base material containing pile, the method including: a first process of mixing 15 to 25 wt. % of urethane resin glue to an acrylic foamed resin to produce 100 wt. % of a mixture, thereby obtaining an adhesive; a second process of subjecting the adhesive to viscosity adjustment to adjust viscosity thereof to 3000 to 6000 cps; and a third process of applying the adhesive to the carpet tile base material by using a screen mesh having a mesh thickness of 20 m or more and less than 100 m and an opening area ratio of 40% to 60%.
FLOOR CARPET WITH ELECTROMAGNETIC SHIELDING
A floor carpet for an automobile comprises a first layer of polyester carpet pile, a second layer including an electromagnetic shield, the electromagnetic shield including a grid of conductive metal fibers molded into a matrix of thermoplastic material, and a third layer including a sound dampening backing made from one of wool and polyurethane, wherein, the first layer, second layer, and third layer are molded together as a unitary piece that is shaped to conform to the contour of a floor panel within an automobile and adapted to be immovably installed within the automobile, the electromagnetic shield extending across substantially all of the floor carpet to provide electromagnetic shielding across substantially the entire floor of the automobile.
