01 Temperature
Storage Temperature: Maintain warehouse temperature at 25°C ±3°C.
Temperatures above 40°C can accelerate molecular chain breakage in spandex, leading to permanent loss of elasticity.
Low temperatures may cause spandex to become stiff and brittle, affecting performance.
02 Humidity
Storage Humidity: Keep relative humidity at 65% ±5%.
Humidity above 70% increases the risk of mold and may cause spandex to stick to packaging materials.
Excessively low humidity can dry out spandex, raising the risk of filament breakage during processing.
03 Light Exposure
Store in a well-ventilated area, avoiding direct sunlight and strong UV exposure.
UV rays can cause oxidation, reducing spandex strength and causing fading.
04 Packaging
Keep in original sealed packaging to prevent:
Contamination by dust and impurities.
Oxidation due to prolonged air exposure.
05 Storage Conditions
Place on pallets or shelves (not directly on the floor) to avoid moisture absorption.
Keep away from heat sources, open flames, and chemicals (e.g., sulfur dioxide, nitrogen oxides), which may degrade spandex or pose fire hazards.
