Abstract
The invention discloses a processing technology for manufacturing leather by waste leather. The method comprises the processing steps that (1), the smashed waste leather is subjected to tanning treatment; (2), the tanned leather is subjected to dyeing treatment; (3), the dyed leather is subjected to fat liquoring treatment; and (4), the leather subjected to the fat liquoring treatment is subjected to retanning treatment. With the adoption of the scheme disclosed by the invention, the processing technology for manufacturing the leather by the waste leather is simple in operation and high in finished product rate, and the manufactured leather is low in cost and good in wear-resisting performance.
Description
Technical field
The present invention relates to the leather preparation field, particularly relate to a kind of complete processing of utilizing waste and old cladding to make leather.
Background technology
The Chinese leather industry is optimized structure through adjusting, and has begun to take shape in the whole nation that a collection of division of labor based on specialization is clear and definite, characteristic outstanding, the pulling local economy has been played leather production characteristic zone and the specialized market of very important effect.As everyone knows, the daily necessitiess such as fur clothing, leather shoes, corium sofa belong to easy loss product, and it updates than very fast, throw away a lot of waste and old claddings because of natural renewal, wear and tear every year, not only cause the pollution of environment, also cause the waste of material.And behind the scrap leather and the pulverizing of corium tankage with various animals, the leather that allotment industrial chemicals processing and fabricating forms, its surface processing technique is the same with the skin of having a shave, the embossed leather of corium, the hide edge is more neat, utilization ratio is high, low price, but the skin body is generally thicker, intensity is relatively poor, setting process product and the par belts such as a suitable for making par briefcase, pull bar bag, club cover.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of waste and old cladding that utilizes simple to operate and makes the complete processing of leather, and the leather quality of making is good, wear resisting property is good, can be used for making the daily necessitiess such as sofa, case and bag.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of complete processing of utilizing waste and old cladding to make leather is provided, comprises following processing step:
(1) the waste and old cladding after will pulverizing carries out tanning and processes,
(2) processing of dyeing of the cladding after tanning is processed,
The cladding that (3) will dye after processing carries out the stuffing processing,
(4) cladding after the stuffing processing being carried out retanning processes.
In a preferred embodiment of the present invention, described tanning treatment solution PH remains on 3.5-4.5, and described tanning treatment temp remains on the 25-50 degree, and the described tanning treatment time is 10-15 hour.
In a preferred embodiment of the present invention, described dyeing treatment solution PH remains on 4.5-5.5, and described dyeing treatment temp remains on the 45-65 degree, and the described dyeing treatment time is 2-5 hour.
In a preferred embodiment of the present invention, described stuffing treatment solution PH remains on 4-6, and described stuffing treatment temp remains on the 40-70 degree, and the described stuffing treatment time is 1-2 hour.
In a preferred embodiment of the present invention, described retanning treatment solution PH remains on 4-6, and described retanning treatment temp remains on the 25-55 degree, and the described retanning treatment time is 1-2 hour.
The invention has the beneficial effects as follows: the present invention utilizes waste and old cladding to make that the leather cost that the complete processing of leather is simple to operate, yield rate is high, be made is low, wear resisting property good.
Embodiment
The below is described in detail preferred embodiment of the present invention, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
A kind of complete processing of utilizing waste and old cladding to make leather comprises following processing step:
(1) the waste and old cladding after will pulverizing carries out tanning and processes, and utilizes trivalent chromic ion that the collagen group of hide fiber is coupled together, and gives leather plentiful feel, increase the intensity of the anti-stretch-draw of leather, anti tear, select vegetable tanning agent, the leather that the filling personality is good, hardness large, make is abundant
(2) processings of dyeing of the cladding after tanning is processed gives cladding certain color, and key is to improve the combination rate of dyestuff and hide fiber, improves the intensity of dyestuff and hide fiber combination, water-fastness by force,
The cladding that (3) will dye after processing carries out the stuffing processing, allows cladding absorb an amount of stuffing material, prevents stiff plate of cladding, cracking,
(4) cladding after stuffing is processed carries out retanning and processes, and can replenish the tanning effect, improves content of tannin, makes physical properties of leather more even, and that improves leather goes out the sanction rate.
In addition, described tanning treatment solution PH remains on about 4, and described tanning treatment temp remains on 35 degree, and the described tanning treatment time is 13 hours.
In addition, described dyeing treatment solution PH remains on about 5, and described dyeing treatment temp remains on 50 degree, and the described dyeing treatment time is 3 hours.
In addition, described stuffing treatment solution PH remains on about 5, and described stuffing treatment temp remains on 60 degree, and the described stuffing treatment time is 1.5 hours.
In addition, described retanning treatment solution PH remains on about 5.5, and described retanning treatment temp remains on 40 degree, and the described retanning treatment time is 2 hours.
The leather that the complete processing that the present invention utilizes waste and old cladding to make leather processes, can be used for making sofa, case and bag etc. is not too high daily necessities to the leather quality requirement, its Costco Wholesale is low, wear resisting property good, water-fastness, arrange well.
Be different from prior art, the present invention utilizes waste and old cladding to make that the leather cost that the complete processing of leather is simple to operate, yield rate is high, be made is low, wear resisting property good.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification sheets of the present invention to do, or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
