    摘要: Process for transforming the residues left after tanning without chroming and the products thereby obtained, based on the process of homogenising (2) the raw material (1), which consists of the leftovers of the tanning industry, such as remnants of skin with hair, trimmings, suede, etc. A mineral acid (3) is added to the mixture, as are semi-metals and metals (4) with a valency of 0, phenol and phenolate (15). The mixture is put in a pressure vessel (5) and is filtered (6) to separate the liquid portion (7) and the solid part (9), which can be neutralised (10) or treated with micro organisms (13). This process is intended to be used in the leather and fur industry as well as in agriculture.

    摘要: A novel pre-tannage system for leather comprises treating the pelt or hide with a zeolite material in a first pre-tannage step and thereafter treating the pelt or hide with one or more modified aldehyde tanning agents. In this condition the pelt or hide is suitable for a number of different tanning steps namely chrome tannage, vegetable tannage, synthetic tannage or a combination of these.

    摘要: A process is disclosed for preparing a suede leather product from animal hides. The hide is scalded before tanning and the finished product can be washed and ironed in a manner similar to a woolen garment. The hide is pretanned in formaldehyde, neutralized in sodium bicarbonate, tanned with a basic chrome solution, neutralized with sodium sulfate, and dyed with a direct color dye. More specifically, an outer suede product is obtained from the external corium of the skin, instead of the flesh side, with the result that less expensive sheepskin acceptable to the trade can be used in place of top grade kidskin and goatskin suedes. In a preferred practice of the method, the hide is burnt twice in scalding steps carried out in a swelling state, soon after first and second fleshing steps and, prior to a bating step. The burning affects the entire thickness of the fibrous grain layer by exposing the upper layer of the corium by soaking the hide in the third solution of sodium sulfide after a third fleshing step. The process obtains a soaped-water washable skin capable of maintaining a soft condition and avoiding fading of the dye. The washable condition is obtained by soaking the dyes, greased with egg yolk, in hot water.

    摘要: The present invention concerns a process for the softening of furs while at the same time taking the greatest possible care of the appearance of the hair. The process of this invention comprises contacting a fur with an acid aqueous liquor containing an acid protease from a fungus strain of the genus Rhizopus rhizopodiformis, said acid protease being effective in the pH range of from about 2.5 to 6.5.

    摘要: Hides may be cured and pretanned by: treating raw hides with a sodium hydroxide solution so as to react the lipid material in order to cause formation of soaps, limited attack on protein material present in the hides, and swelling of the collagen in the hides; adding sodium chloride to the sodium hydroxide solution in order to enable this salt to be taken up from the solution by the hides, causing an increase in the strength of the swollen collagen; dehairing the hides; treating the hides with sodium sulphite solution so as to add strength to the swollen collagen; treating the hides with a mixture of quaternary ammonium salt, and a calcium salt in order to precipitate any soaps present and to place the ammonium salt within the remaining hide material and to separate facia tissue from the remaining hide material; and pickling the hides with an acid solution so as to effect a size reduction and strengthening of the swollen collagen. If desired, the hides may be bated prior to being pickled. The so-cured hides have properties which are related to the properties of the ammonium salt. The resulting hides can be further treated in accordance with conventional tanning practices.
