Tam sim no, cov ntaub ntawm cov ntaub yog feem ntau natural fibers thiab artificial fibers. Piv txwv li, paj rwb yog ib tug natural fiber nrog zoo breathability thiab noo noo nqus, tab sis nws muaj tsis zoo elasticity thiab yooj yim deform. Artificial fiber, raws li lub npe qhia, yog fiber ntau synthesized raws li kev thov, uas daws qee qhov tsis zoo ntawm cov fiber ntau. Spandex, ib hom polyester fiber uas yog chemically synthesized, kuj hu ua elastic fiber vim nws elasticity zoo heev. Cov khaub ncaws fabrics feem ntau tov nrog sib txawv proportions ntawm spandex kom elasticity thiab kev nplij siab, thiab yog dav siv.
