Vim hais tias cov dej dav hlau siv cov dej ntws cov nyhav dej ntau, muaj qee qhov kev cai rau cov kev siv roj ntawm cov phom ntau thiab cov thickness ntawm lub fiber. Nws yuav tsum tau hais tias lub xov tooj tawg thiab phom nyhuv muaj roj hydrophobicity, xws li cov ntaub thaiv polyester, nylon phuam ntoo thiab lwm cov khoom fibre hluavtaws; txoj kab ntim ntawm cov fib fais yog tsim ntawm 33 thiab 500 dtex, thiab cov fiber ntau dhau vim dej haus tsis txaus hlo nqus yuam kom ruaj khov.
