专利汇可以提供Surface texture for fibrous boards专利检索,专利查询,专利分析的服务。并且An aesthetically pleasing texture is imparted to wet-laid fibrous mats by distributing a layer of solid expanded particles of synthetic thermoplastic resinous foamed material on the upper surface of the mat. The particles are then pressed into the wet lap to embed the particles in the fibrous material and the wet lap is subsequently heated to reduce the volume of the particles and leave depressions in the surface which result in a unique random surface texture.,下面是Surface texture for fibrous boards专利的具体信息内容。

1. A METHOD OF TEXTURING THE SURFACE OF A WATER-LAID LAP OF ENTANGLED FIBERS COMPRISING: A. FORMING A WATER-LAID LAP OF ENTANGLED FIBERS: B. SUBSTANTIALLY UNIFORMLY DISTRIBUTING A LAYER OF DISCRETE PARTICLES OF A FOAMED SYNTHETIC ORGANIC THERMOPLASTIC RESINOUS MATERIALS ON ONE SURFACE OF THE WATER-LAID LAP OF ENTANGLED FIBERS SUCH THAT MOST OF THE PARTICLES ABOUT ONE ABOTHER BEFORE PRESSING THE WET LAP, C. PRESSING THE PARTICLES INTO THE WET-LAP TO EMBED THE PARTICLES IN THE WET LAP, AND, D. HEATING THE WET LAP TO REDUCE THE VOLUME OF THE FOAMED MATERIAL AND LEAVE DEPRESSIONS IN THE SURFACE WHICH PRODUCE A UNIQUE RANDOM SURFACE TEXTURE.
1. A method of texturing the surface of a water-laid lap of entangled fibers comprising: a. forming a water-laid lap of entangled fibers; b. substantially unifOrmly distributing a layer of discrete particles of a foamed synthetic organic thermoplastic resinous materials on one surface of the water-laid lap of entangled fibers such that most of the particles abut one another before pressing the wet lap; c. pressing the particles into the wet lap to embed the particles in the wet lap; and, d. heating the wet lap to reduce the volume of the foamed material and leave depressions in the surface which produce a unique random surface texture.
2. The method of claim 1 wherein the thermoplastic material is selected from the group consisting of polystyrene, polyethylene, polypropylene, poly(vinyl chloride), poly(methyl methacrylate), nylon, and copolymers and blends thereof.
3. The method of claim 2 in which the thermoplastic material is polystyrene.
4. The method of claim 2 including the step of painting the surface of the resulting board after the heating step to alter the visual appearance of the board and to help bind the thermoplastic material to the surface of the board.
