What kind of fabric is polyester fiber with spandex?
Polyester fiber plus spandex is spandex.
Polyester fiber: polyester; elastic fiber: spandex. Namely: polyester and spandex interwoven fabric. Or wrapped or coated
Polyester fiber refers to polyester fabric (the fabric does not fade, no deformation, and volatile moisture), elastic fiber refers to spandex (the fabric costs more, do not fade, sweat absorption, ventilation, non deformation)
Spandex is the abbreviation of polyurethane fiber, it is a kind of elastic fiber. Spandex filament which is composed of a plurality of general, generally 10D/ root, there are even 15D/ root, 20D/ root, root number theory less, evenness is better, because the opportunity to overlap form rate is less, the production of dry spinning solution DMAC is harmful to human liver, 10D/ containing control 0.5mg/kg, such as 15D/ the root is 0.7mg/kg, more than the standard. The production of Spandex, for the winding tension, cylinder number, fracture strength, fracture elongation, forming of oil adhesion amount of elastic recovery and so on, they should pay special attention to these problems directly affect the weave, especially in the production of knitted single-sided cloth more should pay attention to.
