【発明の詳細な説明】 （産業上の利用分野） 本発明は床革と銀面からなる銀付き人工皮革の人工銀
面に関するものである。Description: TECHNICAL FIELD The present invention relates to an artificial silver surface of artificial leather with silver comprising floor leather and a silver surface.
（従来の技術および背景） 製品革（銀付き革）の製造における副産物である床革
は、強度的に不均質であり、また薄くするとその強度が
著しく低下するという欠点があるので、その用途は、工
業用手袋、袋物素材などに限定されている。(Background Art and Background) Floor leather, which is a by-product in the production of product leather (silvered leather), is disadvantageous in that it is inhomogeneous in strength, and its strength is significantly reduced when thinned. , Industrial gloves, bag materials, etc.
一方、床革は、吸・放湿性に富み、柔軟で且つ広い温
度範囲に渡って動的弾性率が殆ど変化しないという、合
成高分子化合物には見られないユニークな性質を有して
いる。On the other hand, floor leather has a unique property not found in synthetic polymer compounds, that is, it is rich in moisture absorption and desorption properties, is flexible, and has little change in dynamic elastic modulus over a wide temperature range.
そこで、床革を基材としたものと銀付き革に匹敵する
機能を有する人工皮革部分（本明細書において、人工銀
面という）とを複合することによって、床革の付加価値
を高め、床革の新たな用途展開を図る試みがされつつあ
る。Therefore, by adding a material based on floor leather and an artificial leather portion having a function comparable to that of silvered leather (referred to as an artificial silver surface in this specification), the added value of floor leather is increased, and floor leather is added. Attempts are being made to develop new uses for leather.
ところで、この人工銀面には、「柔軟であること。

特有の柔軟性を欠き、床革との接着性に問題があり、さ
らに通気性を有しない。However, no artificial silver surface having these functions has been provided so far. For example, when a synthetic resin alone is used as a relatively inexpensive material for the artificial silver surface, even if it can obtain a certain degree of heat resistance and abrasion resistance, it lacks the flexibility peculiar to leather, and is not compatible with floor leather. There is a problem in adhesiveness, and furthermore, it has no air permeability.
（発明が解決しようとする課題） 本発明はこのような状況に鑑みてなされたものであ

熱性・耐摩耗性に優れ、さらに 通気性に優れた人工銀面を提供することにある。(Problems to be Solved by the Invention) The present invention has been made in view of such a situation, and its object is to be flexible, have good adhesion to floor leather, and have excellent heat resistance and wear resistance. Another object of the present invention is to provide an artificial silver surface having excellent air permeability.

工銀面を第二の発明とする。(Means for Solving the Problems) In order to achieve the above object, the gist of the present invention is to provide a leather powder of 100 parts by weight, a synthetic resin, a functional group at both ends and which do not react with the synthetic resin. The first invention is an artificial silver surface composed of a compounded and kneaded mixture of parts by weight of a polymer compound, and 100 parts by weight of leather powder, a synthetic resin, and a reaction with a synthetic resin having a functional group at both ends. A second aspect of the present invention is an artificial silver surface which is obtained by mixing and kneading 20 to 25 parts by weight of a polymer compound and silk fiber.

と、上記閉曲線の形成が阻害される。(Action) The reaction between the functional group of the collagen of the leather powder and the polymer compound having a functional group at both ends and not reacting with the synthetic resin is, so to speak, an arc on the surface of the collagen fiber, and has a functional group at both ends. Form a closed curve with the polymer compound as a chord,
The closed curve is filled with synthetic resin, and since the synthetic resin does not react with the polymer compound, it is flexible and has excellent heat resistance and abrasion resistance without being affected by the characteristics of the synthetic resin. Thus, an artificial silver surface having excellent adhesion to floor leather can be obtained. However, with respect to 100 parts by weight of leather powder, when the polymer compound of the present invention is less than 20 parts by weight, the closed curve is not formed, while when the polymer compound of the present invention exceeds 25 parts by weight, the closed curve is not formed. Formation is inhibited.
さらに絹繊維を添加することにより、通気性が大幅に
改善される。Furthermore, the breathability is greatly improved by adding silk fibers.
