この発明は、皮革製品、建材、家具、衣料等に用いられ
る皮革の床革と布地の張り合わせからなる複合材料に関
する。The present invention relates to a composite material made of a laminated layer of leather and fabric used for leather products, building materials, furniture, clothing, etc.
従来から、皮革は、皮革製品、建材、家具、衣料等の多
くの用途に幅広く用いられている。Conventionally, leather has been widely used for many purposes such as leather products, building materials, furniture, and clothing.
ところで、皮革は、銀と呼ばれる表皮部分と、床革とか

に用いられている。
すなわち、床革は、２Ｍ以下に薄くスライスすることが
できるが、その引き裂き強度、引っ張り強度が銀に比較
して極めて小さいものである。従って、床革は余り利用
されず捨てられているのが、現状である。
そこで、この発明者らは、薄くスライスされた床革の一
側面に接着剤を介して補強用の布地を貼着して複合材料
にすれば、捨てられる安価な床革を利用することができ
るのではないかと考えた。
しかしながら、液状の接着剤を用いたところ、皮革本来
の風合が得られなかった。
すなわち、銀のように皮革の繊維が緻密に絡まっている
ものであれば、接着剤が皮革の中に浸透しにくいため、
皮革自体の風合が損なわれることがないが、床革の場合
、繊維が緻密さに欠けボーラスな部分が非常に多く存在
するため、床革の内部や他側面に達するまで接着剤が浸
透してしまう。
したがって、接着剤が硬化すると、床革まで剛直させて
しまい、皮革本来の風合を得ることができなかった。
この発明は、このような事情に鑑みて、床革を利用して
天然皮革の風合を備え、かつ、充分な強度を有する複合
材料を提供することを目的としている。By the way, leather is made up of an outer skin called silver and a floor leather, of which only silver is used for the above-mentioned purposes. That is, although floor leather can be sliced into thin slices of 2M or less, its tear strength and tensile strength are extremely small compared to silver. Therefore, the current situation is that floor leather is not used much and is thrown away. Therefore, the inventors found that by attaching reinforcing fabric to one side of thinly sliced floor leather using adhesive to create a composite material, it is possible to use cheap floor leather that would otherwise be thrown away. I thought it might be. However, when a liquid adhesive was used, the original feel of leather could not be obtained. In other words, if the leather fibers are tightly intertwined, such as silver, it is difficult for the adhesive to penetrate into the leather.
The texture of the leather itself is not impaired, but in the case of floor leather, the fibers are not dense and there are many bolus parts, so the adhesive may penetrate into the interior of the floor leather and reach other sides. I end up. Therefore, when the adhesive hardens, even the floor leather becomes stiff, making it impossible to obtain the original feel of the leather. In view of these circumstances, an object of the present invention is to provide a composite material using floor leather that has the feel of natural leather and has sufficient strength.

ィルムを用いることが好ましい。In order to achieve this purpose, the present invention provides a composite material made by thermocompression-bonding thinly sliced leather floor leather and a desired reinforcing fabric via a thermoplastic film. Further, as the thermoplastic film, it is preferable to use a vinyl chloride resin film.

って行った。The present invention will be described in detail below with reference to drawings showing embodiments thereof. FIG. 1 shows an embodiment of the composite material according to the present invention in a cross section viewed from the side. As shown in the figure, in this composite material A, a reinforcing fabric 3 is adhered to one side of a thinly sliced floor leather 1 via a thermoplastic film 2 serving as an adhesive. That is, the thermoplastic film 2 sandwiched between the floor leather 1 and the reinforcing fabric 3 is melted by thermocompression bonding, and a portion of it enters the uneven surfaces of the floor leather 1 and the reinforcing fabric 3, resulting in its anchoring effect. The two are glued together. Therefore, unlike a liquid adhesive, the adhesive does not penetrate deep into the floor leather 1, and the floor leather 1 does not become rigid. The floor leather 1 can be made of any animal, and is preferably sliced to a thickness of 2n or less. The fabric 3 is not particularly limited as long as it can be reinforced. Natural fibers such as cotton, silk, wool, and rayon. Polyester, acrylic. It may be a woven fabric or a non-woven fabric formed from synthetic fibers such as nylon or blended fibers thereof. Examples of the thermoplastic film 2 include, but are not limited to, vinyl chloride resin, vinyl acetate resin, synthetic rubber, natural rubber, acrylic resin, epoxy resin, urethane resin, chloroprene resin, etc. Comparisons of vinyl chloride resin and the like below 150°C It is preferable to use a material that melts at a relatively low temperature. FIG. 2 shows another embodiment of the composite material according to the present invention in a cross section viewed from the side. As shown in the figure, in this composite material B, floor leather 1 is adhered to both sides of a fabric 3 via a thermoplastic film 2, respectively. Examples will be described in detail below. (Example 1) Cow leather was 0. Prepare cotton sateen sliced into 74 inch thick pieces, 130 g/m'' thick, and a 100 μm thick vinyl chloride resin film made of 100 parts by weight of polyvinyl chloride with an average degree of polymerization of 1300 and 45 parts by weight of dioctyl phthalate. Then, a vinyl chloride resin film was sandwiched between the floor leather and cotton sateen, and heat at 120°C was applied from the cotton sateen side to create a composite material. (Example 2) Floor leather with a thickness of 1.10fi and a fabric weight of 80g/
A composite material was obtained in the same manner as in Example I except that m2 polyester was used. The obtained composite material did not impair the original texture of bed grass. The tensile strength and tear strength of the composite materials obtained in Examples 1 and 2 above were measured at thicknesses of 0. It was measured along with 83 pieces of cow leather and silver, and the results are shown in Table 1. As shown in Table 1, all of the composite materials according to the present invention exhibited tensile strength and tear strength close to that of silver. In addition,
The tensile strength and tear strength were measured according to JIs-K6550.

る。As described above, in the composite material according to the present invention, the thinly sliced leather floor leather and the desired reinforcing fabric are thermocompression bonded via a thermoplastic resin film, so that the thermoplastic film is melted by the thermocompression bonding. The adhesive penetrates into the uneven surfaces of the floor leather and reinforcing fabric, and the two are bonded together, preventing the adhesive from penetrating deep into the floor leather. Therefore, it is possible to obtain a composite material having sufficient strength without impairing the original feel of the floor leather. Furthermore, since the floor leather that was conventionally discarded is used, products using inexpensive leather can be manufactured. In addition, if a vinyl chloride resin film is used as the thermoplastic film, it can be bonded at a heating temperature of 150°C or less, so the floor leather or fabric will not be damaged by heat, making it a better composite material. can be obtained.
