Application of Dehumidifier in Leather Industry
When it comes to leather, wetness is likely its worst foe. Leather is very hygroscopic, meaning it absorbs moisture from the air at every stage of the manufacturing process. Excessive moisture encourages the growth of germs such as fungus and bacteria, resulting in leather breakdown.
As a result, the quality of the product deteriorates and it loses its shine.When the leather product is completed and ready for sale, it must be stored in a humidity-controlled environment to avoid regaining moisture.
In order to keep leather in good condition, the relative humidity should be kept below 40%. In the leather sector, a dehumidifier comes in helpful, especially in a humid nation like Bangladesh.
Advantages of dehumidifier in Leather Industry
Enhance/regulate leather product quality
By keeping the proper temperature and humidity during the manufacturing process of leather products, you may avoid product stagnation or loss, as well as significantly enhance product quality, such as by avoiding hygroscopic materials and products from fusing or sticking.
Prevent Condensation
Condensation should be avoided by shielding open goods from the elements. Equipment can be harmed by condensation. Condensation is more likely in cold rooms or places with high humidity levels due to manufacturing activities. These issues can be resolved with the use of an industrial dehumidifier.
Reduce bacterial and fungal development in the leather items
Leather products are often manufactured in warm, humid, and poorly ventilated place. As a result,dehumidification is the greatest technique to prevent fungus and bacteria from growing in the leather items.
Type of Dehumidifier Used in Leather Industry
Leather may be used in a variety of ways. From high-fashion clothing to furniture to automobile upholstery, you can easily find an example of leather items practically anywhere.
The use of desiccant rotor air drying technology in storage areas preserves the acceptable relative humidity and essential airflow conditions for products and materials storage. The desiccant rotor passes the air that has to be dehumidified (process air).
In a particular silica gel rotor, water molecules are adsorbed. The second air stream, which is warmed to 90-140 °C, regenerates the desiccant rotor. Warm wet air is used to eliminate humidity from the facilities.
How It Works?
Mode 1
This mode of functioning uses a single common fan to handle both process and reactivation air flows. Due to the pattern of air flows depicted on the diagram, maximal heat recovery occurs in this situation. This approach simplifies installation and provides for the lowest dew point feasible.
Mode 2
This is the most typical mode of functioning, and it enables for highly effective air drying down to about 0% RH.
Mode 3
Heat is recovered in this mode of functioning. During the regeneration process, the desiccant wheel soaks up the heat. Reactivation air is therefore pre-heated and partially dehumidified before being fed into the reactivation area through the heater.
After all leather is often quite durable, it is commonly employed in hard-wearing applications on trendy objects. Throughout the tanning procedure, variations in ambient humidity may have a considerable influence on the tensile strength of leather, leaving it either easier or more difficult to break.
This has been a long-standing problem. If you want to make leather with the proper amount of softness or strength for its intended usage, you will need to be able to sustain the appropriate humidity levels. It is also worth mentioning that humidity has a stronger effect on chrome-tanned leather than on vegetable-tanned leather.
The bottom line for all these issues would be to upgrade to dehumidification technology in order to maintain the leather quality and strength by controlling moisture at an optimum level.
