Abstract:
A preparation method for artificial leather, includes applying a weaving process. The weaving includes adopting at least two groups of warp or weft yarns, and weaving each group of yarns into a monolayer structure to form at least two monolayer structures. Each of the monolayer structures is woven with some of the warp and/or weft yarns in such layer or with some of the warp and/or weft yarns in another layer to form a number of connecting points, such that at least two monolayer structures arranged in an orderly manner as two laminates are connected with each other by the weaving process, thereby forming a multi-layer integrated base fabric. The method includes bonding the base fabric and a resin layer together to form an artificial leather; and punching holes multiple air vent holes in the leather distributed in the resin layer and base fabric in the thickness direction.
Abstract:
The invention provides for a method of manufacturing artificial turf (1000). The method includes creating a polymer mixture, such as polymer mixture (400), where the polymer mixture is at least a three-phase system. The polymer mixture includes a first polymer, a second polymer and a compatibilizer. The first polymer is a polyamide (PA) and the second polymer is a polyethylene (PE). The first polymer is included in an amount of 0.125 percent to 5 percent by weight, the second polymer is included in an amount of 60 percent to 97 percent by weight and the compatibilizer is included in an amount of 0.375 percent to 15 percent by weight. The first polymer and the second polymer are immiscible, and the first polymer forms polymer beads surrounded by the compatibilizer within the second polymer.
Abstract:
A low-weight carpet tile and process for making the same, wherein the carpet tile comprises a facecloth having a plurality of face yarns tufted through a primary backing, an extruded polymer secondary backing layer, and a reinforcing scrim layer partially embedded within the extruded polymer secondary backing layer. The top surface and bottom surface of the carpet tile are defined by the facecloth and the reinforcing scrim layer, respectively. A polymer-based resin is extruded onto the facecloth to form an at least substantially uniform secondary backing layer, and the reinforcing scrim layer is laid onto the extruded polymer secondary backing layer while the extruded polymer secondary backing layer remains above a softening temperature for the resin. The entire multi-layer web is then passed through a nip to embed the reinforcing scrim layer into the extruded polymer secondary layer, and the entire web is chilled.
Abstract:
An interior trim part made by a method that includes the steps of bringing a fiber web onto a conveyor, needlepunching the fiber web to form a base in contact with the conveyor, and introducing a binder component on the base. The binder component introduced on the base is a thermoplastic polymer in solid form. The method includes a step for heating the base to cause the thermoplastic polymer making up the binder component to penetrate the base over a thickness smaller than the thickness of the base.
Abstract:
A laminated sheet includes a base cloth layer having a porous structure obtained by impregnating a woven fabric, which has a tear strength by a trapezoid method of 150 N or more in the longitudinal direction and 100 N or more in the lateral direction, with a resin composition containing a polyurethane resin and an organic flame retardant, and a skin layer layered on the base cloth layer, and has plural air holes penetrating in the thickness direction.
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 carpet is constructed of a face yarn comprised principally of a bulked continuous filament carpet face yarn or a bulk staple carpet face yarn wherein the face yarn comprises principally a bundle of drawn and crimped bi-component filaments, and wherein each such filament consists essentially of an outer lengthwise sheath of a dyeable polymeric material surrounding a core of a different polymeric material, and wherein the two polymeric materials are not dyeable by the same method. A particularly advantageous filament structure comprises a nylon sheath surrounding a polyester core. The nylon sheath may be dyed or pigmented. For automotive and similar usage, a polyester sheath surrounding a core of, for example, polyethylene, may be preferred.
