摘要： The present invention relates to a method for tanning animal skins, comprising the following steps: - Staining and pickling the animal skin in an aqueous solution, - reducing the liquid content of the animal skin, - substituting at least part of the liquid quantity removed in the previous step from the animal skin by a tanning solution that contains the tanning agent to be absorbed by the animal skin in a quantity that equals an excess of no more than 80%, and – treating the animal skin comprising the tanning solution with compressed gas in a pressure container for a time period of at least 15 minutes. A method of said kind is largely free of waste water, optionally even completely free of waste water, and produces high-quality tanned leathers or furs with short treatment times.

摘要： The present invention relates to a novel method of recovering and recycling active tannins from spent vegetable tanning liquors. Using a low molecular weight alcohol as the extraction agent produces an alcohol fraction or precipitate containing extracted active tannins, and leaves virtually all non-tannins in the aqueous phase of the spent tanning liquor. The methods and resulting chemical mixtures of the present invention have a variety of uses and applications. The method can be applied to freshly produced or aged spent vegetable tanning liquors. The methods are further applicable to dried forms of spent tanning liquors through aqueous reconstitution of dried ReTan, followed by alcohol extraction. The recovered chemical mixture contains recovered tannins which can be recycled through combination with fresh tanning liquors to form an improved tanning liquor.

摘要： The invention relates to a method for tanning hides, comprising the following steps: softening the hides in liquid at a pH value in a range of approximately 7 to approximately 10, unhairing the hides in liquid at a pH value of up to 13, dewatering the dripping-wet hides by 5 to 40 wt%, treating the moist hides in a pressure vessel at a pressure of 5 to 60 bar for a pressure treatment time of 60 to 360 minutes, wherein the pressure is built up by feeding carbon dioxide, introducing a tanning solution into the pressure vessel, wherein the mass of the tanning solution preferably corresponds at least substantially to the mass by which the dripping-wet hides have been dewatered in the dewatering step, lowering the pressure in the pressure vessel at least substantially continuously to ambient pressure over a pressure-relief time period of 15 to 90 minutes. Consequently, the method according to the invention leads to significantly reduced wastewater, and thus significantly reduced environmental impact, in relation to known tanning methods while achieving at least the same quality of the tanned leather.
摘要翻译：本发明涉及一种鞣制皮革的方法，包括以下步骤：将pH值在约7至约10的范围内软化液体中的皮革，将pH值高达13的液体中的皮革脱毛，脱水滴湿湿皮5〜40重量％，在压力容器中以5〜60巴的压力处理湿皮，压力处理时间为60〜360分钟，其中压力通过进料二氧化碳，引入鞣制溶液进入压力容器，其中鞣制溶液的质量优选至少基本上对应于脱水步骤中滴水湿皮已经脱水的质量，至少基本上连续地将压力容器中的压力降低至减压时间为15〜90分钟时的环境压力。因此，根据本发明的方法导致显着减少的废水，从而相对于已知的鞣制方法显着降低了环境影响，同时达到至少相同质量的鞣制的皮革。
