Dapre elastik elongation gwosè ka divize 3a(1) elastik elastik yarn, elastik elongation 30 30 pousan ~50 pousan , ak thermoplastic chofe mete ak false twist deformation oswa knife edge gege deformation nan filaman yarn, spandex elastik filament yarn konpoze te fè nan filament yarn, itilize pou pwosesis elastik sere, chosèt, swisid, sports rad rad elatriye. (2) Low Low elastisite yarn, elastik elongation sou 20 pousan ~30 , elastisite yarn dezyèm chalè mete tretman filament yarn, yarn yarn spandex elastik filaman yarn kòm nwayo yarn ak melanje staple fib yarn yarn elastik fib fib itilize pwosesis low elastisite men dwe gen eksteryè twal mèb twal 2c elatriye.
