When the raincoats produced by raincoat manufacturers are in use, some products are not waterproof. So what is the reason why it is not waterproof? Today, I will give you a brief introduction!
Speaking of the reason why it is not waterproof, I believe many people know that this is mainly caused by its substandard quality. In the production process, a paraffin emulsion slurry containing aluminum salts needs to be used. After the paraffin is emulsified, it will become small particles, which are distributed on the fibers of the cotton cloth, and the distribution is relatively uniform, and this paraffin is compatible with the water advantage, so this has the effect of waterproofing, but if you use If it is an inferior product, it will have the effect of not being waterproof.
In order to reduce the occurrence of this situation, you must pay attention to this problem when purchasing, and go to a regular raincoat manufacturer to buy, so that you can buy high-quality products and prolong its service life.
