Conventional technology The materials conventionally used as interior materials for vehicles include:
A thin fabric such as a film, knitted fabric, or non-woven fabric is attached to the surface of a resin product, or a fiberboard-like molded product impregnated with a thermosetting resin or a foamed polyurethane sheet is attached to the surface of the product. Those with a surface material pasted are mainly used. In both of these conventional methods, the inside of the interior material (window side) is a molded product impregnated with resin or cardboard, so it has little elongation, and therefore it can be used depending on the shape of the vehicle. There is a drawback that it is difficult to withstand mold matching, especially so-called deep drawing molding, to match the shape of interior materials used in interior materials, and for example, deep drawing molding with a depth exceeding 20 cIn is considered a national disaster. These conventional interior materials have no problem when used as flat or gently curved interior materials, but resin plates and resin-impregnated fiberboards always have a large amount of M, and cardboard cannot be deep drawn. In addition, even if they had initial rigidity, they would break if subjected to large deformation, so there were many car models that could not be installed inside the vehicle. Another drawback of conventional interior materials is that it is necessary to finish the surface of the core-side molded product, which has low elongation as described above, by pasting it with a film or fabric in order to prevent it from being exposed to the outside (surface side) of the vehicle interior material. The point is that there is.

C. Detailed explanation of the invention Deep drawing is possible by increasing the elongation of the window side of the material - two points: the binding and the fact that the interior material is made mainly of fibers, making it unnecessary to attach a film, etc. to the surface of the interior material. It is. The present invention solves these two problems by creating a web consisting of main fibers and adhesive fibers, which retains its shape by partially bonding the main fibers with at least some of the adhesive fibers, and especially on the surface of the interior material. The apparent density of the side web and the window side web are different, and the basis weight of the entire interior material is 200 to 1.50 (M'/♂
The structure is as follows. In particular, the apparent density of the web layer on the surface side of the interior material is set to 0.4 f/cd or less, and that of the web layer on the window side exceeds 0.3 floA.
And the difference between both densities is at least Q, 1f/J, preferably 0.
31/ctA or more, more preferably 8 side webs are 0.9
~ By creating a web layer with a high apparent density, i.e., a hard web layer, such as 1,3f10A, it is expected that the 8-side web will have a hardness that allows deep drawing, and the surface side web will have a flexible finish. It is. By doing this,
The interior material of the present invention does not require the finishing operation of attaching a film or fabric to the surface side, which is essential for conventional interior materials, making it possible to shorten the process. This, of course, also leads to energy conservation.

As far as the present inventors know, there has been no vehicle interior material obtained by bonding main fibers with adhesive fibers as in the present invention, and the present inventors believe that the present invention is a novel interior material.

以下本発明の内装材について詳述する。The interior material of the present invention will be described in detail below.

First, the interior material of the present invention basically has a density difference of 0.17/d between a web layer with an apparent density of 0.4F/6A or less and a web layer with an apparent density of more than 0.32A. Any interior material may be used as long as it can be divided into two layers having the above-mentioned properties, and to that extent, the interior material does not need to be derived solely from a laminate of two or more webs as the initial starting material. However, a preferred embodiment is one obtained by heat-treating a stack of two or more webs to soften or melt bond at least some of the adhesive fibers in the web to the main fibers. However, depending on the selection of heat treatment conditions, by changing the heat treatment conditions for the surface side and window side of one web of main fibers containing adhesive fibers,
As a result, the difference in apparent density between the front side web and the 8th side web can be kept within the above range. Accordingly, the present invention is characterized in that the main fibers have a density difference between the outer core webs due to the bonding of adhesive fibers,
It exhibits a so-called two-layer structure in its density. Furthermore, the second feature of the interior material of the present invention is that its basis weight is 200 to 1.500 f/nt. The reason for providing such a difference in apparent density between the two layers in the present invention is to make one hard and the other soft, and the density difference is 0.1 f/d or more, preferably 0.3 f/J.
It is advantageous for the purposes of the invention that there be more than one.

That is, the preferred web apparent density of the interior material is preferably 0.4 t/- or less on the surface side and 0.7 f/crA or more on the window side, particularly 0.9 to 1.3 y/ctA. Furthermore, in the interior material of the present invention, a film, other web, resin-impregnated paper, knitted fabric, etc. may be interposed between both web layers, but even in that case, the surface side web and the 8th side web of the interior material may be interposed between the two web layers. must satisfy the above conditions.

First, the main fibers in the present invention include an 8-side web,
Various organic synthetic fibers, recycled fibers, natural fibers, inorganic fibers, or mixtures thereof are used for both the surface side web. The main fibers in the 8-side web are preferably thick fibers in order to provide rigidity to the molded product, and the fineness is preferably 6 to 20 d1, preferably 10 to 15 d1, and more preferably hollow fibers. The appropriate length is 30 to 80 cm. On the other hand, the main fibers in the front side web need to provide a flexible surface, but depending on the part used as an interior material, severe abrasion resistance is required, and the fiber thickness must be selected according to the application. . For example, if flexibility is important, a fineness of 2 to 6 d is appropriate; if abrasion resistance is considered, a fineness of 6 to 20 d is appropriate; and a length of 3 (
A value of 1 to 80 is appropriate. Here, the main fibers in the surface side web do not necessarily have to be of the same material as the main fibers in the 8th side web, but in particular, since they are used on the surface, they must be made of a material with good light resistance and a color with good light resistance. need to be. Furthermore, it is preferable that the main fiber has specific properties such as antifouling properties, antistatic properties, flame retardant properties, etc., either as a raw material or as a result of post-processing.

Next, the adhesive fiber in the present invention will be explained. It must be one that softens or melts at a temperature below the melting point of the above-mentioned main fiber, and such thermoplastic components include, for example, polyolefin, polyamide, and polyester. polymers are used. Adhesive fibers are fibers in which the entire fiber is made of the thermoplastic component, and the entire fiber softens and melts at the heat treatment temperature, or the component that melts at the treatment temperature and the component that does not melt are in a core-sheath shape. Composite fibers with a bimetallic or seabird-like cross-sectional shape may also be used, and in consideration of shrinkage during melting, it is preferable to use composite fibers because of their low shrinkage. especially,
Considering that the material is exposed to high temperatures during use in automobiles, there is a possibility that the material may be deformed or its surface condition may change after being molded as an interior material. For this reason, it is desirable that the adhesive fiber preferably has a melting point of 130° C. or higher. However, due to the deterioration of the main fibers due to the processing temperature during molding of interior materials, or from the viewpoint of productivity, the appropriate processing temperature is often 160 to 220°C, and therefore the melting point of adhesive fibers is 130 to 200°C. temperature, more preferably in the range of 150°C to 180°C. In addition, the adhesive fibers of the window side web and the front side web do not necessarily have to be made of the same material; in particular, the adhesive fibers of the front side web have light resistance, coloring, stain resistance, antistatic properties,
It is preferable that various properties such as flame retardancy are imparted to the material as a raw material or as a result of post-processing.

When a composite fiber is used as the adhesive fiber, the composition of the melting component/non-melting component is polyethylene/polypropylene, polyethylene/polyester, polyethylene/polyamide, polypropylene/polyester, polypropylene/polyamide, copolyester/polyester, Various combinations such as polyester/polyamide, copolyamide/polyester, and copolyamide/polyamide are possible, and the combination and composition ratio should be selected as appropriate depending on the main fiber used and the molding heat treatment temperature for the interior material. I can do it. Since the adhesive fibers are softened and melted, their thickness and length do not have a great effect on the final product, but from the point of view of card passability during web production, the fineness is 2 to 20 d1 length. 30~
80■ is appropriate.

When producing the web according to the present invention, these main fibers,
The adhesive fibers are thoroughly blended separately in the eight side web and the front side web in the cotton blending process, and then made into a web using card or random univer and laminated to form the fiber layer which is the starting material of the present invention. Although common, in some cases it can also be obtained by subjecting a single layer web to different molding conditions for the core and surface.

The important point in the present invention is the mixing ratio of the main fiber and the adhesive fiber, which has a great influence on the properties of the final product. The web on the 8th side mainly exhibits rigidity and shape retention after molding. Therefore, in the window side web, the adhesive fibers are the main ones, and the ratio of main edge m/adhesive fibers is 4.
5155 to 10/90 is suitable. In addition, when the adhesive fiber is a composite fiber, the ratio of molten component/non-melt component also affects the adhesive fiber, but the remaining non-melt component will play the role of the main fiber, so in extreme cases, the adhesive It is also possible to make the window side web only from the composite fibers used as the synthetic fibers. On the other hand, since the surface web is required to have a soft or felt-like appearance, it is mainly made of fibers.
, the ratio of main fiber/adhesive fiber is 55/45 to 90/1
0, preferably 65/35 to 80/20. Here, when the proportion of adhesive fibers increases, a smooth plastic-like surface is often obtained even if the molding temperature or pressure is lowered. On the other hand, if the amount of adhesive fibers is less than 10 inches, the surface-based fibers will not be bonded and fixed, resulting in a significant decrease in wear resistance, which is unsuitable.

As described above, web A is a typical starting material for the present invention.
As main fiber/adhesive fiber=45155~10/90

In the present invention, after such 2s webs are laminated, at least a portion of the adhesive fibers are subjected to softening and melting treatment under pressure or no pressure. The heat treatment conditions are uniform heat treatment on the front and back sides of the laminated web, and are below the melting point of the main fibers and above the softening point of the adhesive fibers, and the heat treatment causes the main fibers in the web to soften the adhesive fibers, At the same time as the web is temporarily bonded by the molten material, the entire web is densified by shrinkage. In the present invention, it is necessary to subsequently perform reheating treatment and pressure treatment.

That is, since the desired product cannot be obtained only by the first stage of uniform heat treatment, the second stage of non-uniform heat treatment is always required. In other words, non-uniform heat treatment means that the treatment temperature must be within the same range as in the first stage, but the important point is that the front and back sides of the temporarily bonded and shrunk web after the first stage heat treatment (i.e., the interior When the material is used as a material, it is necessary to give different heat treatment effects to the front side and the side (8), so different heat treatment temperatures are set and applied. This point is the most distinctive feature of the manufacturing method of the present invention, and is the second point in the manufacturing method.
The feature of the present invention is that the second-stage non-uniform heat treatment is performed at the same time as pressure treatment, that is, heating and pressure molding (hot press), or that pressure treatment, that is, cold press is performed during cooling after the non-uniform heat treatment. The object of the present invention can only be obtained by pressing or cold pressing.

As described above, in the manufacturing method of the present invention, uniform heat treatment on the web → non-uniform heat treatment and simultaneous hot press treatment or sequential cold press treatment are essential steps. There is no problem in applying needle punching treatment. Especially web A
, B. In the case of an improved embodiment of the present invention in which a film or other sheet-like material is interposed between B, needle punching is effective. In addition, especially when a film is interposed, #1, which partially softens and melts the film together with the adhesive fibers in the web, is effective in imparting rigidity, and when a film is interposed, the film shrinks slightly. Therefore, sufficient shrinkage should be achieved during the first soaking process. Otherwise, there is a risk that the film will shrink during the second stage of non-uniform heat treatment, resulting in a wrinkled molded product as a whole of the interior material. In this regard, in order to keep the shrinkage small, measures can be taken such as using a film with a low shrinkage rate or using composite fibers as adhesive fibers.

The molded product of the present invention can be used in various parts of a vehicle. In this case, parts that are in close contact with a part of the body do not require much rigidity, but in the case of parts that are not in close contact or interior materials that have a fairly large area, there is a considerable need for rigidity in terms of ease of handling and sway during use. Rigidity is required. In order to compensate for this, it is possible to interpose a thermoplastic resin film as described above between webs A and B, or to disperse thermoplastic resin as uniformly as possible between the webs for reinforcement.
These are merely improved embodiments of the present invention. Among these, it has been found that the former method, that is, the film-interposed method, is preferable, and in that case, a film thickness of about 50 to 300 μm is preferable. Here, if the film thickness is less than 50 μm, there is virtually no effect of improving rigidity;
When μ is exceeded, needle breakage is observed.

Furthermore, other than films, it is also effective to use paper such as kraft paper with a basis weight of 100 to 200 f/m impregnated with a phenol resin, etc., and then heat treated to advance the crosslinking stage to 50 to 80 degrees. When applying a needle punch to a web with this sheet-like material inserted, the paper is not very hard and is easy to process, and the cross-linking stage is over 100 due to uniform heat treatment and non-uniform heat treatment. The product will be able to exhibit sufficient rigidity.

In the hot press method, the adhesive fibers are compressed against the main fibers in a sufficiently softened and molten state, so the molding surface tends to become plastic-like, and the shape retention is difficult when the molded product is removed. It is important to take it out because it is difficult to deform and is easily deformed. However, it is preferable to use a mold with one side at a high temperature and the other side at a low temperature because it facilitates removal and allows the high-temperature treated side to be shaped like plastic and the low-temperature treated side to be shaped like felt. On the other hand, in cold pressing, the adhesive fibers are heated to sufficiently melt them during heat treatment before pressing, and are cooled at the same time as compression molding during pressing to develop shape retention, so they can be removed immediately after pressing, increasing productivity. expensive. Therefore, cold pressing is preferable as a manufacturing method for the molded product of the present invention. According to the research of the present invention,
When performing cold pressing, if the temperature of the mold surface is below 50°C, the surface of the molded product will be almost the same as that of a mold at room temperature, and in general, it will not become a very smooth plastic-like surface and will be felt. It will be like that. Furthermore, when the surface temperature of the mold exceeds 50°C, particularly 70°C or higher, the surface of the molded product is quite smooth and dense, but does not have the same smoothness as plastic. The surface temperature of the mold is 120'
When the temperature exceeds C, the surface becomes plastic-like as in the case of hot pressing, and the rigidity becomes high. Based on the results of cold pressing as described above, when manufacturing the interior material of the present invention, as a method of finishing the surface side like felt and hardening the window side, after sufficiently melting the molten component of the adhesive fiber, By setting the side mold temperature to 50° C. or lower and the window side mold temperature to 70° C. or higher, a molded product with a good surface and a highly rigid core can be manufactured by one molding.

As mentioned above, the cold press method is suitable for press molding in the present invention. Therefore, the optimal manufacturing method for obtaining the interior material of the present invention is to uniformly heat-treat the web laminate with hot air or the like, then perform non-uniform heat treatment by changing the heat treatment temperature on one side and the other side of the web, and then This is a cold pressing method that changes the contact temperature on both sides.
