の用途に好適な天然人造複合皮革に関する。TECHNICAL FIELD The present invention relates to a natural artificial composite leather suitable for use in furniture, vehicles, bags, shoes, clothing, gloves, hats and the like.
従来の技術と問題点 此の発明における、床皮とは、牛皮、羊皮、馬皮、など
の原皮をスライスして銀面層を分離した後の網様層を指
し、粗い繊維組織からなる皮層であるため、従来から、
商品価値の少ないものである。Conventional technology and problems In the present invention, the term “dermis” refers to a net-like layer obtained by slicing a rawhide such as cowhide, sheepskin, horsehide, etc. to separate a silver surface layer, and a skin layer composed of a coarse fiber tissue. Therefore, from the past,
It has little commercial value.
従来、此の床皮の上面に着色した柔軟性ビニール系合成
樹脂からなる皮膜層を形成し、該皮膜上面にシボ模様を
付した擬革は知られている。（実公昭２６−１２３９
１）。Conventionally, a pseudo leather is known in which a coating layer made of a colored flexible vinyl-based synthetic resin is formed on the upper surface of the floor skin, and a grain pattern is formed on the upper surface of the coating. (Actual public 26-1239
1).
しかし、上記の擬革は、床皮の上面に設けたビニール系
樹脂によって、強靭性、耐久性の向上は得られても、基
皮である床皮の保有している透湿性という特長を損なう
ものであった。However, the above-mentioned pseudo leather has a toughness and durability improved by the vinyl-based resin provided on the upper surface of the floor leather, but it impairs the moisture permeability characteristic of the floor leather as the base leather. It was a thing.
そこで、最近、開発された透湿性ウレタン樹脂を採用し
て、これを塗工すれば、問題点は容易に解決し得るよう
に思われるが、人造皮革層の床皮に対する接着力を充分
にし、且つ床皮の特性を活かた商品価値のある複合皮革
を得るには、以下に説明するような、技術を必要とする
ことに到達したのである。Therefore, it seems that the recently developed moisture permeable urethane resin can be applied to coat the problem, but the adhesive strength of the artificial leather layer to the floor skin can be made sufficient, In addition, in order to obtain a composite leather having a commercial value that makes the best use of the characteristics of the floor leather, it has been necessary to use the technique as described below.
問題点を解決するための手段及び作用 即ち、本発明では、透湿性ウレタン樹脂より成る人造皮

部当たり、０乃至１００重量部の皮粉を混合する。尚、
皮粉の添加量が１００重量部を越えると、接着力が低下
する。Means and Actions for Solving the Problems That is, in the present invention, an artificial leather layer made of a moisture-permeable urethane resin is used as two layers of an adhesive layer and an outer skin (surface) layer, and the adhesive layer directly bonded to the floor skin is usually With a thickness of 10 to 40 μm, 0 to 100 parts by weight of skin powder is mixed with 100 parts by weight of the moisture-permeable urethane resin as a coating material. still,
If the amount of skin powder added exceeds 100 parts by weight, the adhesive strength will decrease.
此の皮粉とは、前記の原皮をスライスした時に出来る粗
いシェービング粉と銀面層をバフィングした時の出来る
細かいペーパー粉とから成るもので、その平均粒径は、
通常１０乃至３００ミクロンであるが、ミキサー等で砕

適性の面で望ましい。This leather powder consists of coarse shaving powder produced when the above-mentioned raw leather is sliced and fine paper powder produced when buffing the silver surface layer, and its average particle size is
Usually, it is 10 to 300 μm, but it is desirable to grind with a mixer or the like to 100 μm or less from the viewpoint of dispersibility and coating suitability.
また、前記の表皮層は、通常１０乃至５０ミクロンの厚
さとして、皮粉の添加量は、透湿性ウレタン系樹脂１０
０重量部当たり、３０乃至３００重量部とする。３０重

表面に型押し、表面処理を施してもよい。The skin layer is usually 10 to 50 μm thick, and the amount of skin powder added is such that the moisture permeable urethane resin 10
It is 30 to 300 parts by weight per 0 parts by weight. If it is less than 30 parts by weight, the moisture permeability is not sufficient, and if it exceeds 300 parts by weight, the dispersibility in the resin is lowered and the suitability for coating is deteriorated. In addition, a coloring agent, a filler, another resin, or the like can be mixed in this skin layer, if necessary.
The surface may be embossed and surface-treated.
