Cattle wet white leather which is tanned by multiple metals and a tanning agent which are matched is used as raw stock, various vegetable extracts are matched with the cattle wet white leather to carry out two-time retanning filling treatment, and after retanning, a novel green chrome-free tanning agent is added to further carry out tanning extract fixing and stuffing treatment; in an implementation process, a chrome tanning agent is not used, even if a large amount of vegetable tanning agents are used, the circumstance that brightness of colorful crust leather is affected by the color of tanning extracts is avoided, the production technology is simple and is easy to implement, the production cost is proper, and upper leather is suitable for being produced in a large scale; and the upper leather which is manufactured by the production technology is chrome-free and formaldehyde-free, the shrinkage temperature is greater than or equal to 90 DEG C, the tearing force is greater than or equal to 40N, the air permeability and the water permeability are good, the crust leather is even and full in color, bright and beautiful in hue and high in color fastness, various physical and chemical properties of the crust leather meet the industrial standard, and the subsequent processing performance is good.
Description
Technical field
The present invention relates to tanning chemistry and field of engineering technology, particularly to a kind of technology of cattle hide upper leather without chrome retanned based on vegetable tanning agent.
Background technology
The reserves of China's chromium are few, it is not enough to go around, and the chromium that raw material skin has 20-30% during tanning and retanning can not absorb for it and utilize, discharge along with sewage, cause the pollution of environment and the waste of ample resources, and after China joins WTO, more focus on environmental protection and environmental quality, therefore leather is taked harmonious with environment in producing, environment amenable Leather Chemicals (i.e. green material) and technology (i.e. cleaning technology), increasingly receive publicity and support, the research of leather chrome-free tanning and Chrome-free retanning Technology is the inexorable trend of future development.
In sum, exploitation chrome-free tanning be industry research focus without chrome retanned new technology, be the important component part of clean leather-making technology, be also one of the key point of leather industry sustainable development.
Summary of the invention
Therefore, for above-mentioned problem, the present invention provides a kind of technology of cattle hide upper leather without chrome retanned based on vegetable tanning agent, the described technology implementation process of cattle hide upper leather without chrome retanned based on vegetable tanning agent does not use chrome tanning agent, also will not affect the vividness of colored crust leather because of the color of tannin extract itself even with substantial amounts of vegetable tanning agent, production technology the most easily realizes, and production cost is suitable, is suitable for producing in enormous quantities；And make gained upper leather Chrome-free, formaldehydeless by this production technology, shrinkage temperature >=90 DEG C, tear edge >=40N, there is good gas permeability and permeable gas, crust leather color is the fullest, tone bright-coloured beautiful, color fastness is high, the every physico performance of crust leather is satisfied by professional standard, and properties for follow is good.
For realizing above-mentioned technical problem, the solution that the present invention takes is: a kind of technology of cattle hide upper leather without chrome retanned based on vegetable tanning agent, in turn includes the following steps:
