The culprit of the mildew of shoes - glue
Dec 07, 2018

Glue anti-fungal agents have become a hot topic in recent years. Especially since 2006, developed countries in Europe and the United States have adopted trade protection policies for China, and more and more use environmental protection thresholds to restrict our exports. Although the factory has taken various measures to prevent mold, according to the incomplete statistics of the customs department, in 2006, the annual export of single footwear reached 10 billion pairs. To this end, commissioned by the China Industrial Products Antibacterial Association, we organized a team of 30 experts to track 206 large and medium-sized shoe factories, 83 furniture factories, and 47 handbag factories. We went deep into the first floor of the factory floor, from the material procurement of the factory to the cutting, sewing, (finishing) packaging, warehousing, transportation, we gave an unexpected result, 46.8% of the mold is made of glue As a result, 23.2% of the mold is caused by the packaging, 13.5%, and only 16.5% is caused by the material itself is not clean. This is why the more preventive the mold, the more it is because the glue is not found.

Then why does the glue become the culprit of mildew? First, the general glue is composed of polyvinyl alcohol, white latex, sodium stearate, talcum powder, urea, ethylene glycol, sucrose, flavor, water, etc., slightly stimulated. Flavor, volatile, volatile gas with weak tearing. In order to eliminate the pungent odor in the glue, the glue manufacturer will add a small amount of ammonia water in the glue to balance and play a deodorant effect. At the same time, however, the alkaline environment makes the glue, especially the water-soluble white latex, rich in sugar and protein, providing a large amount of breeding nutrition and food for the mold. Secondly, the Pearl River Delta and the Yangtze River Delta region are subtropical climates. Sea transportation, temperature and humidity vary greatly, increasing the risk of moisture and mildew in the glue.
