Description
Technical field
The present invention relates to leather processing technique field, especially a kind of processing side of high anti-aging type animal's leather of breathing freely
Method.
Background technique
Leather be lost hair or feathers, the Animal Skin of the resulting denaturation without putrefaction of physics, the chemical process process such as tanning, leather is day
What right protein fibre was constituted in three-dimensional space close weave, be mainly to process raw material to be made by the animals cladding such as ox-hide, pigskin,
There is a kind of special grain layer on its surface, has natural graining and gloss, comfortable feel.Continuous development and people in society
During class is evolved, it has been found that some waters or mineral oil have certain flexibility to leather, and raw material skin passes through these
The immersion of tanning agent, so that leather be made to have the physical and chemical performances such as gas permeability, anti-corrosive properties, tear resistance, resistance to tortuosity, skin just has at this time
For the characteristic of leather goods.Till now, leather is divided by purpose can be divided into life leather, national defence leather, work to leather industry
Agricultural leather and culture and sports four classes of leather, can be divided into chrome leather, vegetable leather, chamois leather and combination tanned leather, skin by process for tanning
Leather industry has nowadays been not limited to leather manufacture, and it is many to further relate to process hides, shoemaking, fur clothing, leather hardware and leather machine etc.
Field has formed more complete product chain.However anti-aging is poor during use for leather, many clothing leathers pass through
It phenomena such as will appear color variation, fold after the use of certain time, needs often to be maintained, and leather and fur products is generally saturating
Gas is poor, influences the comfort of people's dress, and therefore, the existing leather manufacture technology in China is improved there is still a need for further to mention
Its high anti ageing property and gas permeability, to further increase the wearing comfort degree of Leather clothing cap.
Summary of the invention
In order to overcome the problems, such as that anti-aging property existing in the prior art is insufficient, permeability is poor, leather and fur products is improved
Anti ageing property and gas permeability, the present invention a kind of processing method of high anti-aging type animal's leather of breathing freely is provided.
The technical solution adopted by the present invention to solve the technical problems is: it is a kind of it is high breathe freely anti-aging type animal's leather plus
Work method, including following procedure of processing:
(1) skin and preparatory processing are selected
(a) classification of raw material skin and select: the raw material skin before going into operation first to processing is classified and organizes production batch；
(b) sundries such as unhairing and bur, dust are removed: the former skin of the production got ready batch is subjected to machine unhairing, Yi Jiqing
Except sundries such as the bur in original paper sheet face and dust；
(c) it washes skin: the hide that step (b) processing obtains being placed in cylinder and is impregnated using clear water, 15~18 DEG C of water temperature, impregnate
Then 6~10h of time will be washed by rubbing with the hands in the hide merging sig water of dipped water, buck washes 15~30min of skin time, removes
Greasy dirt places into 4~6h of rinsing in clear water；
(d) degreasing fleshing: by grease, the dirt on the removal of hide obtained by step (c) surface, removing subcutaneous tissue, draws skin living
Fiber keeps cortex soft；
