Japanese Utility Model Application Publication No. 59-139322 discloses a cloth in which a protective layer is provided on the surface of the cloth to prevent the protruding convex portions from coming off or being worn out. This is a material in which a pattern is formed on the surface of a non-woven fabric using a foamed ink layer, and the surface is covered with a resin coating.By covering the surface of the foamed ink layer with a resin coating, the foamed ink layer rubs directly against other objects. This was done so that they would never match.

し脱落しにくくなっている。As shown in Figures 1 and 2, in the nonwoven fabric interior material (+) of the present invention, the furnace-type expansion agent applied to the nonwoven fabric (2) is applied to the surface of the nonwoven fabric and to the gaps between the constituent fibers of the nonwoven fabric. As this furnace-type expanding agent is compressed and expanded, the furnace-type expanding agent existing between the constituent fibers of the nonwoven fabric (2) expands the gap in the constituent fibers, and expands this. result,
As shown in FIG. 2, a convex portion (4) is formed that protrudes from the surface of the nonwoven fabric (2). Therefore, the constituent fibers of the nonwoven fabric (2) enter the convex part (4), and the convex part (4) itself is strengthened, and the nonwoven fabric (2)
It is firmly fixed by the constituent fibers of the material, making it difficult to wear out and fall off.

わめて優れたものとなっている。Thus, in the nonwoven fabric interior material (1) of the present invention,
The furnace-type expanding agent applied to the nonwoven fabric (2) expands, and a convex part (4) is provided on the surface of the nonwoven fabric (2), but this convex part (4) has no internal parts. Since the constituent fibers of the nonwoven fabric (2) are embedded, even if it rubs against other objects, it will not be scraped off or worn out. In addition, the unique texture of the nonwoven fabric interior material (4), which has convex portions (4) protruding from the surface of the nonwoven fabric (2), can be used as a design, so it is extremely excellent from a design perspective. It has become a thing.
次に、上記構造を有する請求項２記載の不織布内装材の

閏の間隙を充分に押し閏〈ことがてきないからである。The nonwoven fabric (2) of the present invention is preferably one in which the constituent fibers are bonded and fixed in a movable state, and methods for fixing the constituent fibers include entanglement, adhesion with a binder, and other conventionally known methods. A different method can be used. When intertwining constituent fibers, 0.05 to 0
．． It is preferable to intertwine the fibers so that the density is within the range of 3 g/cm3, which means 0.05 g/cm3.
In a bulky state with exa 3 or less, the degree of entanglement is insufficient and the strength as a nonwoven fabric (2) cannot be maintained, while in a dense state with m density of 0.3 g/cwa' or more, the degree of entanglement is insufficient. The temperature is too high, and due to the expansion of the thermal expansion agent, the constituent line &lK
This is because you cannot press the gap sufficiently to make the leap.

Furthermore, the fineness of the constituent fibers is 0.
It is preferably 1 to 50 deniers.

。The thermal expansion agent to be applied to the nonwoven fabric (2) is not particularly limited, but for example, the thermal expansion agent applied to the inside of the outer wall formed of vinylidene chloride-acrylonitrile copolymer, methyl methacrylate-7-acrylonitrile copolymer, etc. Examples include microcapsule types containing low boiling point hydrocarbons such as isobutane and isopentane. Typical examples of such microcapsules include ■:
The outer wall is made of vinylidene chloride-acrylonitrile copolymer, and isobutane is sealed inside, and the maximum magnification temperature is 1.
35°C, ■: The outer wall is made of methyl methacrylate-acrylonitrile copolymer, the interior of which is encapsulated with isobutane, and the maximum magnification temperature is 150°C, ■: The outer wall is made of methyl methacrylate-acrylonitrile copolymer (methyl methacrylate) Examples include those in which the ratio of (1) is smaller than (2), in which n-pentane is sealed and the maximum magnification temperature is 175°C. In the examples, a commercially available microcapsule-type thermal expansion agent (Microsphere-F-50 manufactured by Matsumoto Yushi Pharmaceutical Co., Ltd.) was used.

に十分に入り込ませることができるからである。In addition, when applying the thermal expansion agent to the nonwoven fabric (2), consider the permeability of the thermal expansion agent into the nonwoven fabric (2), the adhesion between the thermal expansion agent and the constituent fibers, etc. It is preferable to use a compounded liquid (3) prepared by adding a synthetic resin emulsion, a thickener, and water to a swelling agent to adjust the viscosity to a predetermined value. The synthetic resin emulsion is preferably, for example, an acrylic emulsion or an ethylene-vinyl chloride copolymer, and the resin component contained in this synthetic resin emulsion allows the thermal expansion agent and the constituent fibers to be bonded together. In addition to this synthetic resin emulsion, the viscosity of the liquid mixture containing the thermal expansion agent is adjusted by adding a thickener and water. It is desirable that the viscosity of the compounded liquid be within the range of toooo to 5QOOOCPS. This is because, within this range, when the same compounded liquid (4) is applied to the nonwoven fabric (2), the thermal expansion agent is applied to the gaps between the constituent fibers of the nonwoven fabric (2), preferably the nonwoven fabric (
This is because the thermal expansion agent (2) can be sufficiently penetrated between the constituent fibers of the surface layer portion on the side to be applied.

At this time, depending on the resin component of the synthetic resin emulsion contained in the compounded liquid (3), the thermal expansion agent in the compounded liquid (3) and the nonwoven fabric (2)
The structure m fibers will be bonded together.

よって強固に固着された状態となる。Next, the nonwoven fabric (2) coated with a thermal expansion agent is heat-treated. The heating temperature is not particularly limited as long as it is within a temperature range that allows the thermal expansion agent to expand. Due to this heating, the thermal expansion agent expands, and the thermal expansion agent present in the gaps between the constituent fibers expands the gaps between the constituent fibers. As a result, as shown in Figure 2, the surface of the nonwoven fabric (2) Convex part (4) in a more protruding state
will be formed. The constituent fibers of the non-woven fabric (2) enter this convex portion (4), which strengthens the convex portion (4) itself and also strengthens the non-woven fabric (2). It will be in a state where it is firmly fixed by the constituent fibers of the cloth (2).

とができるという理由か・らである。In addition, as shown in FIG. 3, the nonwoven fabric (2) may have a multilayer structure in which two or more sheets are laminated. In this case, any material may be used, but at least the nonwoven fabric (2) on the side to which the thermal expansion agent is applied should be such that the constituent fibers are bonded and fixed in a movable state. This is because when the thermal expansion agent is applied, the permeability of the thermal expansion agent increases, and the expansion of the thermal expansion agent pushes open the gaps between the constituent fibers of the nonwoven fabric (2). This is because the convex portions (4) can be easily provided on the surface of the nonwoven fabric (2).

ものであった。The convex portions of the nonwoven fabric interior material thus obtained had the constituent fibers incorporated therein, and had a three-dimensional appearance in which the intertwined state of the fibers stood out. Since such a state can be observed from the outside, the unique texture of nonwoven fabric interior materials has also been utilized for design purposes. Therefore, the nonwoven fabric was not only excellent in abrasion resistance but also excellent in design, and was extremely suitable as an interior material. In addition, the non-lined fabric interior material had flame retardancy and was excellent in terms of fire protection.
