Abstract
The invention discloses a preparation method of essence microcapsules for leather bacteriostasis. The preparation method comprises the following steps: A) stirring 30 parts by mass of essence and 0.06-0.6 part of polyvinylpyrrolidone to obtain a mixed material; B) adding 1.2-1.6% of Arabic gum solution into the mixed material and uniformly emulsifying to obtain an emulsion; C) adding 1.2-1.6% whey protein solution and fully and uniformly stirring at normal temperature to obtain a mixed liquid; D) adjusting the pH value of the mixed liquid to 3.0-4.0 and stirring and embedding to obtain the essence microcapsules; E) adding the essence microcapsules into a leather sample to retan; and F) vacuumizing the leather sample which is treated by the step E) in a closed drying box of a vacuum drier, so that the air pressure in the drying box is reduced below the standard atmospheric pressure and the essence microcapsules are filled in leather. The essence microcapsules are applied to leather products, so that the essence microcapsules have a remarkable inhibiting effect on mildews, bacteria and the like on leather.
Description
Technical field
The invention belongs to leather production field, particularly relate to a kind of preparation method for the essence microcapsule of mould fungus inhibition bacterium in leather.
Background technology
Leather belongs to natural organic high-molecular one, and itself is just containing abundant collagen matter and fat.In addition, the grease used in the course of processing of leather, carbohydrate, the compositions such as inorganic salt, these all become the good nutrition source of mould-growth.So, in use procedure after leather, along with the loss of grease, on the one hand, there is aging stiff phenomenon in leather, on the other hand, leatherware very easily produces mildew, serious outward appearance and the use properties that must have impact on leatherware, 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 fungistat for leather finish, for some aging leatherware, although certain antibacterial effect can be had, 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 invention provides a kind of preparation method of the essence microcapsule antibacterial for leather, making essence microcapsule be filled in leather, reach the effect of long-term mould fungus inhibition bacterium.
Adopt following technical scheme: a kind of preparation method of the essence microcapsule antibacterial for leather, is characterized in that taking following steps for this reason:
A) get essence and 0.06-0.6 part polyvinylpyrrolidone of 30 parts by massfraction, at room temperature fully stir and make it mix, obtain compound;
B) while stirring to steps A) compound in add the gumwater that mass concentration is 1.2%-1.6%, emulsification evenly obtains emulsion, and described compound is 30:(54-66 with the mass ratio of gumwater added);
C) to step B) add the lactoalbumin soln that mass concentration is 1.2%-1.6% in the emulsion of gained, stir under normal temperature, obtain mixed solution, described emulsion and the lactoalbumin soln volume ratio added are 70:(25-35);
D) be under the condition of 25-45 DEG C in temperature, by step C) after the pH value of mixed solution prepared is adjusted to 3.0-4.0, stirs embedding 4-7h, obtain essence microcapsule;
E) pH value be 3.0-4.0, under temperature is the condition of 25-45 DEG C, by step D) in obtained microcapsule join in the leather sample of 12cm*12cm, retanning is carried out by leaching chrome tanning method with chrome tanning agent in steam unit, in microcapsule shell through a passage, maintenance temperature is 100-120 DEG C, and the hot steam of humidity 50% ~ 80% to penetrate in leather and leather is not wet;
F) by through step e) leather sample that processes be placed on Vacuumdrier close drying case in vacuumize, make loft drier internal gas pressure drop to below standard atmospheric pressure, complete and essence microcapsule is filled in leather.
Further, steps A) described in essence be rose scent beta-cyclodextrin essence.
In preparation process, step e is in microcapsule shell through a passage, and hot steam to penetrate in leather and leather is not wet, and by humidity, temperature is passed to rapidly unexpanded microcapsule, cause microcapsule shell to be softened, microcapsule are expanded immediately and defines larger microballoon.Through F) leather rapid drying can be made, essence microcapsule is filled in leather and reaches fungistatic effect.
Compared with prior art, having advantage is: 1) have obvious restraining effect to the mould on leather, bacterium etc. in the present invention, efficient, environmental protection, health; 2) to have consumption few for fragrant microcapsule, and lasting fragrance, can cover leather peculiar smell, improves leather class; 3) leather is a three-dimensional porous type carrier, compared with other materials, more easily absorb chemical materials, the intensity of absorption also can be higher, after volatile oil is prepared into 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, realize becoming more meticulous of leather products; 4) the distinctive fragrance of volatile oil can not only cover up the peculiar smell of leather, also has effect of many health cares.
