【発明の詳細な説明】
〔産業上の利用分野〕
本発明は皮靴工程で使用される鞣剤に係わり、更に詳し
くは、クロム化合物、アルミニウム化合物、および、合
成タンニンの3成分系より構成される鞣剤、および、そ
の製造方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tanning agent used in the leather shoe process, and more specifically, it is composed of a three-component system of a chromium compound, an aluminum compound, and a synthetic tannin. The present invention relates to a tanning agent and a method for producing the same.
現在、鞣剤としては種々提案され、かつ使用されている
か、主としてクムロ鞣剤が汎用されている。クロム鞣剤
はその優れた菫柔効果と紅済性の故に、−世紀以上に渡
って広く普及してきた。また、クロム鞣剤には種々の塩
基度、および、クロム含有量の差異に基づく各種の塩基
性硫酸クロムが知られ、皮革産業の発展に大きく貢献し
てきた。Currently, various tanning agents have been proposed and used, and Kumuro tanning agent is mainly used. Chrome tanning agents have been widely used for more than a century because of their excellent violet softening and redness properties. Furthermore, various types of basic chromium sulfate based on various basicities and differences in chromium content are known as chromium tanning agents, and have greatly contributed to the development of the leather industry.
しかし、かかる効果的なりロム鞣剤においても、幾つか
の欠点が時代の要請と共に指摘されてきている。この最
大のものは、クロム化合物の環境汚染問題であり、社廃
水中のクロム、皮革スラッジ中のクロムの処理対策が要
求され、種々の研究が行われ、実用化も推進されている
。However, even with such effective ROM tanning agents, some drawbacks have been pointed out in line with the demands of the times. The biggest problem is the environmental pollution problem caused by chromium compounds, and measures are required to deal with chromium in company wastewater and leather sludge, and various studies are being conducted and practical applications are being promoted.
この対策には、
(1)クロム揉廃液を直接循環利用、または、クロム化
合物を沈澱・回収し、再溶解により再利用する方法。Countermeasures include: (1) Direct recycling of chromium milling waste, or reuse by precipitating and recovering chromium compounds and redissolving them.
(2)クロムの皮革への吸着率を、温度、pH1浴量等
の支社条件の改善や、吸着促進剤の使用により増大させ
る方法。(2) A method of increasing the adsorption rate of chromium on leather by improving branch conditions such as temperature and pH 1 bath amount, and by using an adsorption promoter.
(3)クロムを必要最少量使用し、他の鞣剤を併用する
、いわゆる省りロム社方法。(3) The so-called Somi-Rom method, which uses the minimum necessary amount of chromium and also uses other tanning agents.
等が提案され、一部実施されている。etc. have been proposed and partially implemented.

Leather J11', which is made using a tanning agent mainly composed of synthetic tannins and processed in the same manner as the normal chrome toughening method, is superior to the normal chrome tanning method in terms of heat resistance, flexibility, fullness, and dyeability. It is superior to bast leather made by this method, and has 1. In the production of IQ, the tube color is less bluish than that produced by Chrome alone, and the painting process is easier, and the characteristics of natural leather are not impaired. It has better dye penetration and level dyeing properties than single bast leather, allowing for shorter working times.

るものである。Furthermore, when violet leather is made using the tanning agent of the present invention, the rate of neck absorption of chromium into the leather is higher than when tanning is performed using the same procedure as the conventional method using chromium, jl, and IJ agents. The outflow of chromium to the waste liquid is suppressed to less than 1/1 degree. This suggests that the tanning agent of the present invention not only contributes to improving the quality of leather, but also works extremely effectively to reduce environmental pollution caused by chromium compounds in waste liquid.
