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 should not be placed in a place exposed to sunlight, and it should not be stored with sulfur dioxide, nitrogen oxides and other chemical products, causing its decomposition.
Storage period: 20D (3 months), 30D (4 months), 40D-70D (6 months), 100D-280D (9 months), coarser than 420D (12 months), the coarser the Spandex, the longer the storage period.
When weaving, Spandex opens the carton at least 16 hours in advance from the constant temperature warehouse to the workshop and puts it in the weaving workshop to regain moisture to reduce the phenomenon of yarn breakage during weaving.
