Polyester fiber cotton products should be stored in a dry and clean environment. The relative humidity of the warehouse should generally be controlled within a reasonable range to avoid prolonged exposure to moisture, which can affect the material's bulkiness and resilience. The storage area should also have good ventilation to reduce the risk of mold and odor.
Products should be stored off the ground using pallets or shelves to avoid direct contact with the ground. Products should not be stacked too high or subjected to prolonged heavy pressure to prevent compression and deformation of the fiber structure, which could affect subsequent performance. Products of different specifications and batches should be stored separately and clearly labeled for management and quality traceability.
The storage area should be away from open flames, high-temperature heat sources, and highly corrosive substances, and should meet basic fire safety requirements. The warehouse should be equipped with necessary fire-fighting facilities, and the integrity of product packaging and storage conditions should be checked regularly. For materials stored long-term, periodic random inspections should be conducted to ensure that their physical properties and appearance meet usage requirements.
