Spandex should be stored in an environment with constant temperature and humidity. The temperature is between 18-20 degrees Celsius. The lower the temperature, the longer the storage period. The relative humidity is 60%-70%. It is not suitable to be placed in a place exposed to sunlight. It is stored with chemical products such as sulfur dioxide and nitrogen oxides, causing it to decompose.
Storage period: 20D (3 months), 30D (4 months), 40D-70D (6 months), 100D-280D (9 months), thicker than 420D (12 months), the thicker the spandex, the storage period Longer.
When Spandex is weaving, from the constant temperature warehouse to the workshop, the carton is opened at least 16 hours in advance and placed in the weaving workshop to regain moisture to reduce yarn breakage during weaving.
