The above prior art solutions have the following drawbacks: the existing leather clothes are still to be improved because the existing leather clothes are stored for a long time and cannot be found in time once being wetted in the storage process, and the existing leather clothes are easy to get mildewed.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the mildew-proof leather garment to relieve the mildew of the leather garment caused by storage and dampness.

The second purpose of the invention is to provide a processing technology of the mildew-proof fur clothing.

In order to achieve the purpose, the invention provides the following technical scheme:

the mildew-proof fur clothing comprises a fur clothing body, wherein the surface of the fur clothing body is finished by a mildew-proof agent, and the mildew-proof agent comprises the following raw materials in parts by weight:

15-25 parts of acrylic resin;

6-8 parts of N-bromosuccinimide;

2-3 parts of ethyldichlorosilane;

1-2 parts of a catalyst;

a surfactant;

40-60 parts of deionized water.

By adopting the technical scheme, the mildew preventive is sprayed on the surface of the leather garment body to form an inert film to obtain a physical barrier layer, so that microorganisms are prevented from reaching the surface of the leather garment body; the acrylic resin is taken as a carrier, N-bromosuccinimide with mildew-proof effect is added, and stable emulsion is formed under the action of a surfactant, so that a protective film is easily formed when the acrylic resin is sprayed on the surface of a leather garment body; meanwhile, the catalyst can catalyze the reaction of the ethyl dichlorosilane and the acrylic resin, which is beneficial to forming a continuous protective film, improving the moisture resistance, relieving the problem of easy mildew caused by moisture and achieving an effective mildew-proof effect.

The present invention in a preferred example may be further configured to: the mildew preventive also comprises 3-4 parts of diethanolamine and 0.2-0.3 part of p-toluenesulfonic acid in parts by weight.
