Shandong Gaomi Lianchi protective equipment explains how to prevent and deal with moldy shoes

   How to prevent shoe mold? Today I will introduce some methods for you. The details are as follows:       We have known for a long time that under the right conditions, mold can grow on most shoe materials. According to the JACKIE GLASSPOOL report, dealing with this phenomenon continues to be a challenge for companies purchasing raw materials from all over the world. Mold spores are always present in the environment. Although they are generally small and invisible to the naked eye, these spores—much like plant seeds—need to germinate under warm conditions with moisture. If they have the right conditions, mold spores will flourish. If they have a food source, they will thrive and form a dense colony of mold.

      The materials used in footwear construction—such as leather, textiles, and polymeric materials—provide good food sources for mold, and ideal temperature and temperature conditions may exist during transportation or storage. It usually takes 6-8 weeks to take a ship in the Far East to Europe or the United States, including transporting the goods from the factory to the dock, and a large amount of time to allow mold to grow, if conditions are right. 1. Conditions in transportation

      Footwear is usually packed in metal containers and stacked on the open deck of ships for transportation. A temperature and humidity recorder is placed in a container full of shoes shipped from Thailand to the United States. The results show that the conditions in the container vary greatly depending on the voyage. Big. For example, in the first 7 days, the temperature fluctuation, on average, from the peak (at noon) to the valley at night, is about 23°C, and the highest temperature during this period is about 55°C. The temperature change in the container is much more significant than the temperature-on average, the change is as high as 42% in 24 hours, and the highest temperature recorded during this time is 78%. The recorder placed in the shoe box revealed a different picture: the small environment in the shoe box proved to be much more stable than the environment in the container. At the beginning of the voyage, the humidity in the shoe box was kept at 3°C. Changes within the region, slowly rising to a peak of 35°C on the fifth day, and then slowly falling back. The relative humidity changes almost in exactly the same pattern and keeps changing within 3% during these 7 days. 2. Silica gel-not much value?

     The relative humidity inside the container always changes in the opposite direction to the temperature. When the temperature rises, the relative humidity drops; when the temperature drops, the relative humidity rises. This type of temperature and humidity activity is due to the fact that cold air cannot retain as much moisture as warm air. What's interesting is that the small environment in the shoe box is not only much more stable, but also shows another way of temperature and humidity activity. Contrary to the environment in the container, the relative humidity in the shoe box changes in the same direction as the temperature. The data recorded from the shoe box shows that the water in the small environment is absorbed when the temperature drops and is released when the temperature rises. The shoe box and the shoe itself (not the silica gel dryer) are almost certainly responsible for absorbing this water. This conclusion is based on the fact that—perhaps surprisingly—the water absorption capacity of commonly used silica gel is much smaller than that of commonly used leather shoe uppers or commonly used shoe boxes (SATRA's research shows that at a relative humidity of 85% Under the condition of, the ability of commonly used shoe boxes to absorb moisture is 25 times that of commonly used silica gel dry.) Therefore, we can reasonably be sure that any silica gel in the shoe box cannot be responsible for stabilizing the relative humidity of the small environment in the shoe box. In fact, it is likely that the shoebox itself plays an important role in isolating the environment. 3. Restore the affected shoes      Prevention is undoubtedly better than correcting time. However, when faced with a product affected by mold and there is no time to replace it, the only choice is to repair the damaged product or unnecessary inventory. What measures can be taken? It depends on many factors, but more importantly, the location and severity of the mold. If the mold growth is serious, it is likely that the mechanical properties of the material on which the mold grows have been damaged, and it is impossible to be repaired. If the mold has entered the structure of the shoe material—such as PU coating material—it is usually impossible to remove or cover the mold left by the mold. Stain, even if the mold growth is not serious. However, if only mildew grows on the surface of the material (the wax coating on the leather upper), the shoes can usually be repaired very well. Removal of the materials that support the growth of mold also removes mold and mildew caused by it. If the shoes can be dried enough, they will not grow mold again. In any case, this article emphasizes that putting anti-mold sheet or similar products in the shoe box is a wise preventive measure. Fourth, use antibacterial products       If silica gel desiccant does not help, what other methods can be used to reduce the risk of mold problems to a very low level? Controlled use of products that release germicidal chemicals—for example, chlorine may help. Antibacterial products come in various forms, such as self-adhesive anti-mold sheets placed in shoe boxes, and anti-mold paper wrapping shoes. However, it is very important that if you plan to use antibacterial products, you should not only get The permission of the country of production of the shoes and the permission of the country of destination should resist the temptation to use products without sufficient documentation. Reputable companies will be willing to demonstrate the methods they use to ensure that the products meet the intended purpose and provide evidence Prove that the antibacterial agent used in the product is licensed by the target market of the shoes and the country of manufacture.  

    Consumer product regulations around the world have zero tolerance for packaging materials and negligence in the use of antibacterial agents. Recent evidence on the health threats caused by the presence of dimethyl fumarate in furniture and footwear products has proved that the cost of making a wrong decision may be significant. When deciding whether to use an antibacterial product to protect shoes in transit, if there is Any doubts about the need for self-audit testing can now be clearly dispelled.
