Abstract
The invention discloses the preparation method of a kind of essence microcapsule antibacterial for leather, take following steps: A) take the essence of 30 parts and 0.06 0.6 parts of polyvinylpyrrolidones by mass fraction, stirring obtains compound；B) adding the gumwater that mass concentration is 1.2% 1.6% in compound, emulsifying uniformly obtains emulsion；C) add the lactoalbumin soln that mass concentration is 1.2% 1.6%, stir under room temperature, obtain mixed liquor；D) pH value of mixed liquor regulates after 3.0 4.0, and stirring embedding obtains essence microcapsule；E) retanning during microcapsule joins leather sample；F) by through step E) leather sample that processes is placed on evacuation in the close drying case of vacuum drier, and make drying baker internal gas pressure drop to below normal atmosphere, complete and essence microcapsule is filled in leather.Essence microcapsule is applied in leatherware by the present invention, and the mycete on leather, antibacterial etc. are had obvious inhibitory action.
Description
Technical field
The invention belongs to leather production field, particularly relate to the preparation method of a kind of essence microcapsule suppressing mycete antibacterial in leather.
Background technology
It is a kind of that leather belongs to natural organic high-molecular, and itself is just containing abundant collagen matter and fat.Additionally, the oils and fats used in the course of processing of leather, saccharide, the composition such as inorganic salt, these all become the good nutrition source of fungus growth.So, during use after leather, loss along with oils and fats, on the one hand, leather occurs aging stiff phenomenon, on the other hand, leatherware easily produces mildew, the serious outward appearance that must have impact on leatherware and serviceability, in addition, for the leatherware of some contact human body skins, mildew also has damaging effect to human body.At present about the bacteria mildew-proof agent of leather, mainly in the production process such as tanning stuffing of leather.But along with leatherware uses for a long time, antibacterial and mouldproof effect fades away.And the existing antibacterial for leather finish, for some aging leatherware, although can there be certain antibacterial effect, but it can not be made to recover original feel, color and luster and other performances.
Summary of the invention
In order to solve the present situation of above-mentioned prior art, the present invention provides the preparation method of a kind of essence microcapsule antibacterial for leather, makes essence microcapsule be filled in leather, reaches the effect of long-term suppression mycete antibacterial.
Adopt the following technical scheme that for this: the preparation method of a kind of essence microcapsule antibacterial for leather, it is characterised in that take following steps:
A) take essence and 0.06-0.6 part polyvinylpyrrolidone of 30 parts by mass fraction, be at room temperature sufficiently stirred for making it mix, obtain compound；
B) to step A while stirring) compound in add mass concentration be the gumwater of 1.2%-1.6%, emulsifying uniformly obtains emulsion, and described compound is 30:(54-66 with the mass ratio of the gumwater of addition)；
C) to step B) to add mass concentration in the emulsion of gained be to stir under the lactoalbumin soln of 1.2%-1.6%, room temperature, obtains mixed liquor, described emulsion is 70:(25-35 with the lactoalbumin soln volume ratio of addition)；
D) under conditions of temperature is 25-45 DEG C, by step C) the pH value regulation of the mixed liquor prepared to after 3.0-4.0, stirring embedding 4-7h, obtain essence microcapsule；
E) pH value be 3.0-4.0, under conditions of temperature is 25-45 DEG C, by step D) in the microcapsule for preparing join in the leather sample of 12cm*12cm, retanning is carried out by leaching chrome tanning method with chrome tanning agent in steaming device, in microcapsule shell through a passage, keeping temperature to be 100-120 DEG C, the vapours of humidity 50%～80% penetrates in leather and makes leather the wettest；
F) by through step E) leather sample that processes is placed on evacuation in the close drying case of vacuum drier, and make drying baker internal gas pressure drop to below normal atmosphere, complete and essence microcapsule is filled in leather.
Further, step A) described in essence be rose scent beta-schardinger dextrin-essence.
In preparation process, step E is in microcapsule shell through a passage, and vapours can penetrate in leather and make leather the wettest, by humidity, temperature passes to rapidly unexpanded microcapsule, microcapsule shell is caused to soften so that microcapsule expands immediately and defines bigger microsphere.Through F) leather rapid draing can be made, essence microcapsule is filled in leather and reaches fungistatic effect.
The present invention compared with prior art, has the advantage that: 1) mycete on leather, antibacterial etc. are had obvious inhibitory action, efficiently, environmental protection, health；2) to have consumption few for fragrant microcapsule, lasting fragrance, can cover leather abnormal flavour, improves leather class；3) leather is a three-dimensional porous type carrier, compared with other materials, it is easier to absorb chemical materials, the intensity of absorption also can be higher, after essential oil is prepared as the powder of microcapsule " plan solid ", essence microcapsule can stably be present in the space net structure of leather, plays a role stably and lastingly, do not affect the outward appearance of leather, it is achieved becoming more meticulous of leather products；4) the distinctive fragrance of essential oil can not only cover up the abnormal flavour of leather, also has effect of many health cares.
