ECDP flat FDY yarn has good moisture regain. What are the specific requirements for the storage, transportation and use environment of the product?

ECDP flat FDY yarn has good moisture regain, which makes it sensitive to the temperature and humidity of the storage environment. Suitable temperature and humidity environment is the key to ensure the stability of fiber performance. If the humidity of the storage environment is too high, the fiber will absorb a lot of moisture, which will not only easily cause mildew, resulting in mildew spots and odor on the fiber surface, affecting the fiber quality, but also may cause adhesion between fibers, increase the difficulty of subsequent processing, and even cause fiber breakage. An overly dry environment will cause the fiber to lose water, become fragile and easy to break, and reduce the physical properties of the fiber.

Comprehensive and effective moisture-proof measures should be taken in the storage area. Materials with good moisture-proof properties, such as waterproof coatings and moisture-proof panels, can be used for the construction of warehouses to reduce the impact of moisture on fibers from the source. At the same time, the installation of professional dehumidification equipment is also essential. According to the area and humidity of the warehouse, the appropriate dehumidifier model and quantity can be selected to monitor and adjust the humidity in the warehouse in real time.

Ventilation can effectively reduce air humidity, discharge moisture in the warehouse in time, and avoid moisture accumulation around the fiber. At the same time, ventilation can also reduce the chance of microbial growth. In a humid environment, microorganisms are easy to grow and reproduce on the surface of the fiber, which will not only destroy the structure of the fiber, but also produce odor and affect the use value of the fiber. Therefore, the storage area should reasonably set vents or install ventilation equipment, such as exhaust fans, to ensure that the air can flow smoothly. If the weather permits, the doors and windows of the warehouse can also be opened appropriately for natural ventilation, but care should be taken to avoid external moisture directly entering the warehouse.

In the process of transporting ECDP flat FDY yarn, the sealing of the packaging is the key to preventing external moisture from invading. Reliable quality and good sealing performance packaging materials, such as plastic film, moisture-proof cartons, etc., should be selected to package the fiber in multiple layers to ensure that the packaging is not damaged and has no gaps. In addition, an appropriate amount of desiccant, such as silica gel desiccant, calcium chloride desiccant, etc., can be added to the packaging to absorb the trace moisture that may exist in the packaging and further reduce the risk of fiber moisture. After packaging is completed, the packaging should be carefully checked to ensure that the sealing effect is good to avoid moisture in the fiber due to packaging problems during transportation.
