However, the synthetic resin of the resin laminated sheet is the same polymer as the synthetic fiber. Even if it is made of a material, the conventional resin laminated sheet is not suitable for tennis court ground because it does not have a molecular structure in which a polymeric material is oriented like synthetic fibers and is easily stretched and easily worn. It lacked durability, and because the surface was smooth and slippery, the ball was slippery, making it unsuitable for tennis court grounds. Of course, although there were attempts to emboss in order to make fine irregularities on the surface like natural ground and to sprinkle rubber crushed pieces etc. to improve it, a resin laminated sheet that can substitute for artificial grass is Not obtained.

A warp knitted fabric can also be used as the base fabric 11 in the case where the is inserted. The specifications of the fibers used in the fiber web are not particularly limited, but particularly preferred fibers are polyester fibers and polypropylene fibers. The fibrous web may be laminated only on one side of the base fabric 11 and needling may be applied. However, when it is desired to thicken the coating layers 14 and 15 of the resin compositions 12 and 13 to be applied and laminated on the front and back sides, Fiber webs may be laminated on both front and back surfaces.

される。To form a convex portion on the surface of the coating layer 14,
The coating amount of the resin composition 12 may be reduced so that the coating thickness becomes thinner than the apparent thickness of the fluff layer. When the resin laminated sheet 18 is used as a surface material for a tennis court ground, a road surface, a floor in a room or a car, etc.
The surface is made slippery and has a large coefficient of friction, and it is recognized that the surface is free from flicker and the abutted seams are inconspicuous. Therefore, the resin laminated sheet 18
Is used with the surface on which the convex portion 16 is formed facing the front.

ェルトを用いるとよいと言う訳である。Therefore, it is not always necessary to form a convex portion on the other surface 15 (hereinafter referred to as the back surface) of the resin laminated sheet 18 which is the back surface, and the coating layer 15 on the back surface is a foamed layer having a cushioning property. Is desirable. When the back surface of the resin laminated sheet 18 is used as the foam layer (15) and the needle punched felt is used for a double-sided hair cloth, the needle punched felt has a fluff layer with a low basis weight as the surface of the resin laminated sheet 18. The fluff layer having a high basis weight is preferably used as the back layer 15 as the layer 14. More specifically, the needle punch felt is formed by needling the fibrous web laminated on the base fabric 11, and the fibers 20 projected on one side of the base fabric 11 by needling are laminated on the other side. Since it is a part of the fibrous web that is formed, the fluff layer on one side (hereinafter, referred to as a web protruding surface) of the protrusion is the other one side (hereinafter, referred to as a web laminating surface) on which the fibrous web is laminated. It has less basis weight than the fluff layer. Therefore, it is preferable to use the needle punch felt so that the web protruding surface is the front surface layer 14 of the resin laminated sheet 18 and the web laminated surface is the back surface layer 15 of the resin laminated sheet 18.

うこと、その結果、耐久性のある樹脂積層シート１８が
得られる等の理由による。The reason why the needle punch felt is used with the web protruding surface as the surface layer 14 and the web laminated surface as the back surface layer 15 is as follows: (1) Web protruding surface (14)
Then, the needle through hole 21 made by needling
The fluff fibers 20 are bundled upright and are upright, and the vicinity of the needle through hole 21 is the densest part of the fiber density. That is, the web protruding surface (14) is provided with irregularities due to the upright state of the fluff fibers 20 and the density of the fiber density, and when the resin composition 12 is applied thereto, the resin is formed near the needle through holes 21. The composition 12 is easily adsorbed, and a part of the resin composition 12 is pushed up by the surface fluff 19 to easily form a hard and granular convex portion 16.
(2) Then, the fluff fibers 20 at the root of the convex portion 16 pass through the needle through holes 21 and the web laminated surface (1
5), so that the convex portion 16 has a protruding surface (1
It is difficult to separate from (4), (3) Furthermore, since the fibers 19 and 20 and the resin composition 12 complement each other to form the convex portion 16, it is difficult to wear the convex portion 16 That is, as a result, a durable resin laminated sheet 18 can be obtained.

脂組成物１３を塗布して発泡層を形成することが推奨さ
れるのである。On the other hand, on the web laminating surface (15), the laminated fibrous web is thick and swelled to form a flat fluff layer which is still laminated and is applied to the base fabric 1
The foamed resin composition 13 that has penetrated to reach 1 forms a cushion layer (15) which is intimately integrated with the fibrous web. As described above, the cushion layer (15) is not a foam layer made only of a resin, and since the fibers 22 are interspersed inside the cushion layer (15) in a mesh shape, the cushion layer (15) is less likely to expand and contract and has excellent wear resistance as compared with a foam made of only a resin. Unlike the felt having only the fibrous web, the fibers 22 and 22 are connected by the foamed resin composition 13, so that the compression elastic recovery rate and the abrasion resistance are excellent. For this reason, it is recommended that the web protruding surface (14) be the surface of the resin laminated sheet 18 and the foam resin composition 13 be applied to the web laminated surface (15) to form a foam layer.

The resin composition 13 applied to the above may be foamed. However, in that case, the resin composition 13 applied to the web protruding surface (14) has a lower expansion ratio than the foamed resin composition 13 forming the cushion layer (15) on the back surface.

It is also possible to use 5) facing the surface. In that case,
The coating thickness of the resin composition 13 on the web laminated surface (15) is made thinner than the apparent thickness of the fluff layer of the needle punch felt before coating, and the applied resin composition 13 is pressed into the fluff layer with a doctor or the like. As the doctor passes, the fluff 23 projects to the coating layer surface (15) due to the compression elastic recovery force of the fibrous web to form the convex portion 24. This is also the case when a double-sided raised fabric is used for the double-sided fabric. Even when the web laminated surface (15) is used as the back surface, the resin composition 13 is not applied so thick that the fibers 22 are completely hidden under the coating layer 15, and the fluff 23 is projected and recessed. Allowing (24) to be formed on the surface (15) of the coating layer is convenient when the resin laminated sheet 18 is adhered to the substrate 26 via the adhesive (25) for use.

等して最終仕上をすることも出来る。In order to interpose particles having a particle diameter of 0.2 to 1 mm in the non-foamed or low-foamed coating layer 14, the unfoamed or low-foamed resin composition 12 containing the particles is mixed with a doctor or a spray gun. By applying it to the double-sided hair cloth by
It is also possible to disperse the particles on the surface of the double-sided hair-coated cloth on which the resin composition 12 is applied, and entangle the particles with the surface fluff 19 in advance. The latter, that is, the method of entangling the particles is effective when the specific gravity of the particles is heavy and the particles sink into the resin composition and are easily separated when the particles are mixed with the resin composition. In order to smooth the irregularities 16 and 17 on the surface and make the heights of the convex portions 16 uniform, the resin laminated sheet 18 may be passed through a smooth embossing roll. Of course, the resin laminated sheet 18 is laid on the base 26 as a surface material for a ground of a ball game field such as a tennis court or a basketball, a surface material for a passage in a car of a bus or a train, a surface material for a floor, a surface material for a road surface, etc. It is also possible to hang the surface on the roller to make the heights of the convex portions 16 uniform, and to apply a paint to finish the finishing.
