摘要:
A flooring material having a textile pad substructure with a density of greater than 10 pounds per cubic foot is provided. The textile pad has reinforcement and binding fibers. The binding fibers are thermoplastic and are used to bind the reinforcement fibers together. The pad is created by heating and compressing a fibrous textile batt so that it has a density of greater than 13 pounds per cubic foot.

In some embodiment, a method of manufacturing an automobile floor carpet comprises a step of pressing a nonwoven fabric 4, an adhesive film 3 obtained immediately after extruding thermoplastic resin having a melt flow rate of 10 to 1,000 g/10 min from an extruder 20, and a surface skin material 2 piled together in this order with a pair of rollers 21 and 22. With this manufacturing method, an automobile floor carpet excellent in sound absorption performance and also excellent in sound insulation performance can be manufactured.

An automobile wallpaper, and an exterior surface finishing agent for the door trim, seats, and so on, of automobiles, as well as its manufacturing method. To manufacture such automobile wallpaper, a printing process is performed on the surface of a surface material which is currently being used, in order to render a three-dimensional effect to the surface, so as to achieve various luxurious appearances. The three-dimensional effect of the printing is maintained even during the molding process, and it also possesses excellent properties relative to sound absorbency, due to the three-dimensional effect of the surface.
摘要:
Acoustically absorptive carpeting includes a primary layer of fibrous material with yarn tufts extending outwardly therefrom and a secondary layer of thermoplastic material that forms a carpet backing. The carpet backing is rendered porous. A substrate of porous material is attached to the carpet backing. The substrate includes a layer of fine fibrous material attached to a layer of coarse fibrous material. The layers of fine and coarse fibrous material each have respective different acoustic impedances. The layer of coarse fibrous material has fibers in an open, loose configuration. The carpet backing is bonded to the layer of coarse fibrous material with a thermoplastic adhesive material such that the thermoplastic adhesive material encapsulates individual fibers of the layer of coarse fibrous material without extending therebetween.

A reflective metallized material having at least one metal layer with at least one reflective surface that is capable of reflecting radiant energy, and at least one spacing layer to provide void space directly adjacent the reflective surface of the metal layer. The reflective metallized material may be used in a floor covering installation, such as in a carpet backing or carpet underlay, to provide a reflective insulating barrier to the floor covering. When the floor covering is installed, the resultant floor has improved energy efficiency.
摘要:
A sound absorbing carpet according to the present invention is characterized in that a sound absorbing nonwoven fabric layer is integrally bonded to a lower surface side of the surface skin material layer via an adhesive film layer made of thermoplastic resin, and a part of fibers constituting the sound absorbing nonwoven fabric layer are constituted by thick fibers of 11 to 220 desitex, and the adhesive film layer is provided with a number of permeable pores formed by being contacted by the thick fibers.
摘要:
An improved acoustically and thermally insulating fire-retardant composite material suitable for use in structures such as buildings, appliances, and the interior passenger compartments and exterior components of automotive vehicles is provided. The material is comprised of at least one airlaid fibrous layer of controlled density and composition and incorporating suitable binding agents and additives as needed to meet expectations for noise abatement, fire-retardancy, and mildew resistance. Separately, an airlaid structure which provides a reduced, controlled airflow therethrough useful for acoustic insulation is provided, and which includes a woven or nonwoven scrim. A process for the production of the fire retardant nonwoven material is also provided.
摘要:
Sound absorbing/sound blocking products, including trim products formed from a porous fibrous layer backed by a sound absorbing layer and a sound blocking layer for use within vehicles, and methods of making same, are provided. A porous fibrous layer structure including a fibrous layer backing is heated to achieve a fluid or semi-fluid state and then subjected to vacuum to draw air through the fibrous layer backing to create a porous structure. A layer of sound absorbing and a layer of sound blocking material may be applied to the porous fibrous layer backing to provide improved acoustic properties. An underlayment may further be included to provide selected areas of increased thickness and provide tailoring of sound attenuation.
