Ua ntej, cov duab lossis cov qauv luam tawm ntawm daim ntawv sublimation, thiab tom qab ntawd daim ntawv muab tso rau hauv kev sib cuag nrog cov ntaub. Cov ntawv sublimation thiab ntaub ua ke yob rau hauv lub tshuab hloov hluav taws xob, uas nws ua haujlwm kub ntawm ib ncig ntawm 220 degree centigrade. Ntawm qhov kub thiab txias, tus number case molecules hloov ncaj qha los ntawm cov khoom mus rau lub xeev gaseous, thiab tom qab ntawd nkag mus rau hauv cov fibers ntawm cov ntaub. Thaum qhov kub thiab txias, tus number case re-solidifies thiab bonds rau fibers, tsim ib tug ntev daim duab los yog qauv.
