Abstract
The invention relates to a method for tanning-processing animal leather. The steps show follow: In the first step, it adds aluminum sulfate and sodium chloride. In the second step, it adds sodium silicate and hydrochloric acid. In the third step, it adds oxygen titanium ammonium sulfate and sodium sulfate synthesis zirconium. In the forth step, it adds red alum. In the fifth step, it adds adding sodium bicarbonate. In the sixth step, it takes the leather out of the drum, and carries out aging. The invention makes the shrinkage temperature of leather reach 105deg.C, and makes finished inside of the leather meticulous, smooth.
Description
Technical field the present invention relates to a kind of processing method for tanning of animal's leather.
Background technology is well-known, and the chrome tanning agent over-all properties is best, and therefore the field of animal skin process hides is at home and abroad used by extensive, a large amount of at present, and its main drawback is that toxicity is big, pollutes heavy.
And the content of silicon salt in the earth's crust is very abundant, and nontoxic, for other inorganic salt tanning materials can't be obtained, but the separately not anti-storage of silica tanning leather, leather becomes crisp firmly in the storage.Titanium salt has the advantage of fast light, wash resistant and anti-storage as tanning material, and shortcoming is to prepare relatively difficulty of owse separately.Zirconates has the good characteristics of fillibility as tanning material, but is difficult for being penetrated into pelt inside.The leather fine hair of aluminum tanning material tanning is careful, and the pollution of this kind tanning material is less, and shortcoming is that leather shrinking temperature is lower after the tanning.
The processing method for tanning of existing animal's leather generally adopts chrome tanning process, and with the method for chrome tanning report is arranged also in technical literature again with the pre-treatment of aluminium salt earlier.But, still do not have at present a kind of technology that chromium, aluminium, titanium, zirconium, silicon carry out leather tanning that fully utilizes.So existing leather tanning method is not brought into play the comprehensive advantage of above-mentioned these tanning materials, no matter the product that obtains still can not be satisfactory on the physical chemistry Biological indicators still are the finished product impression.
Summary of the invention technical problem to be solved by this invention is, a kind of method of tanning animal leather is provided, by selecting suitable inorganic salt and proportion scale, be equipped with ancillary component, and preferred their using method, fully utilize multiple inorganic tanning material and carry out leather tanning, improve the integrated performance index of leather goods.
Technical scheme of the present invention is as follows:
A kind of method of tanning animal leather is characterized in that: carries out according to following steps,
In the pelt double centner of the first step: pH1.0-2.0, add water 200-300 kilogram, at 2 meters rotary drums of diameter, under the rotating speed 8-10rpm, add Tai-Ace S 150 0.15-0.20 kilogram, sodium-chlor 1.2-1.6 kilogram rotated 3-4 hour;
Second step: add water glass 1.5-2.5 kilogram, hydrochloric acid 0.8-1 kilogram rotated 4-6 hour;
The 3rd step: add titanyl sulfate ammonium salt 0.1-0.15 kilogram, zirconium oxygen base sodium sulfate 0.2-0.4 kilogram rotated 4-6 hour;
The 4th step: add arsenic 0.2-0.25 kilogram, rotated 5-8 hour;
The 5th step: add sodium bicarbonate 0.1-0.5 kilogram, rotated 3-5 hour;
The 6th step: go out drum, took the horse ageing 24-48 hour.
More than order, processing parameter, various material and the usage ratio thereof of each processing step all be key of the present invention, drawing through a large amount of experiments.Though mechanism is still not clear, satisfactory according to this method result of use, what change then such-and-such problem can occur, mainly is the physical and chemical index aspect of finished product and the problem of feel aspect.
The present invention compares with existing method, has following positively effect: at first, combine the advantage of multiple inorganic tanning material, various components act synergistically on the animal pelt, use the back leather shrinking temperature to reach 105 ℃, and the finished product the inside is careful, smooth, good hand feeling, elasticity is better.Secondly, pollute lighter.Three, can save follow-up retanning technology, simplify the operation, reduce whole process hides cost, improve work efficiency.
Embodiment further specifies the present invention below in conjunction with embodiment.
