It can be infected with spot and moisture after, be easy to cause leather mouldy, leather and fur products also will appear expansion and deformation, dimensional stability
Difference is obviously shortened the service life of leather and fur products.
Existing 108251572 A of patent document CN discloses a kind of production method of mildew proof leather, will include following step
Rapid: degreasing rewetting, retanning, neutralization, filling, dyeing and fat-liquoring, solid acid and post-processing are handled, patent text repeatedly by plurality of step
There is no the mildew proof effects of publicly available leather for part, and make effective water-filling between leather fiber, leather fiber evacuation,
It can mutually be slided between fiber and fiber, leather is easy to happen expansion and deformation after water suction, has seriously affected the strong of leather and fur products
Degree and beauty.
Summary of the invention
In order to make up the defect of prior art, the object of the present invention is to provide a kind of preparation sides of antibacterial anti-deformation leather
Method.
A kind of preparation method of antibacterial anti-deformation leather, comprising the following steps:
(1) it retanning: is rubbed being placed in chrome tanning agent after tanning by cuing open the cladding of layer and finishing again, in 41 ~ 43 DEG C of rotary drum tans
5 ~ 6h is made, collagen fabric in leather can be promoted to synthesize, make the homogeneous softness of leather, take out, rushed using deionized water
Wash clean obtains retanning material；
(2) primary drying: retanning material is placed in baking oven, and it is 43 ~ 45% that water content is dried in 37 ~ 39 DEG C, makes cladding surface
Moisture is quickly reduced, and is reduced the porosity on cladding surface, is improved the uniformity of cladding, then reduce temperature to 28 ~ 30 DEG C, continue to dry
Doing to water content is 20 ~ 22%, so that cladding internal moisture is slowly scattered and disappeared, increases the mesh-structured and fibre strength inside cladding, make
Cladding breathable heat insulating obtains primary drying material；
(3) antimicrobial treatment: to the inner face of primary drying material and outside, even application antibacterial agent, quantity for spray are 15 ~ 20ml/ simultaneously
dm2, after spraying by the inner face of primary drying material with interior towards to overlapping, in 10 ~ 15 DEG C of 20 ~ 30h of standing, continuous spray 2 ~
3 times, it is 30 ~ 35% that water content is dried in 45 ~ 55 DEG C, enables cladding uniform pickup antibacterial agent, can increase the glue in cladding
Former protein content, enhances the intensity and wearability of leather, while antibacterial agent can be made sufficiently to be combined with collagen, has leather
Have and stablize permanent antibacterial functions, obtains antimicrobial treatment material；
(4) stuffing: fatting agent will be uniformly smeared in antimicrobial treatment material inner face after the tiling of antimicrobial treatment material, applying amount is 10 ~ 15ml/
dm2, after spraying by the inner face of antimicrobial treatment material with interior towards to overlapping, in 15 ~ 20 DEG C of 4 ~ 5h of standing, make between cladding fiber

Existing 108251572 A of patent document CN discloses a kind of production method of mildew proof leather.
The performance of embodiment and comparative example leather:
36 pieces of ox first layer lether that tanning is completed are randomly choosed, size is 20cm × 20cm, is respectively divided into 12 groups, every group 3 pieces, divides
Not Wei embodiment group and comparative example group, each group carries out the preparation of leather with the method for the group respectively, and water content is after the completion of preparation
10%, it is resistance to DIN53273 detection peel strength (kg/cm), ASTM D-3885 detection abrasion performance, SATRA TM55-1999 detection
Tortuous, ASTMD1148-07A detects color inhibition, and is inoculated with mould in each group leather surface, examines afterwards for 24 hours according to optimum condition culture
The bacteriostasis rate (%) of each group leather is surveyed, and slowly adds water into each group leather, until falling bulging 20min when water content is 80%, detection is each
The size changing rate (%) of group leather, the performance of embodiment and comparative example leather are shown in Table 1.
Table 1: the performance of embodiment and comparative example leather
From table 1 the result shows that, the antibacterial anti-deformation leather that the preparation method of the antibacterial anti-deformation leather of embodiment is prepared,
Peel strength, abrasion performance, resistance to complications, color inhibition, bacteriostasis rate and size changing rate index be substantially better than comparative example, illustrate this hair
The antibacterial anti-deformation leather that the preparation method of the antibacterial anti-deformation leather of bright offer is prepared has good antibacterial and preapres for an unfavorable turn of events
Shape performance.
