Cov xov paj kub yaj sib cais yog hais txog ib hom xov paj uas yog siv los cais cov txheej txheem ntawm cov ntaub ntawv hauv kev tsim cov ntaub ntawv tsis-woven, xws li cov ntaub so thiab cov khoom siv tu cev. Cov xov paj yog melted thaum lub sij hawm tsim khoom thiab ua raws li ib tug binder, tuav cov khaubncaws sab nraud povtseg ntawm cov khoom ua ke thaum lawv tab tom ua. Thaum cov khoom tiav lawm, cov xov paj kub yaj solidifies, tsim kom muaj kev sib raug zoo ntawm cov khaubncaws sab nraud povtseg.
Kub yaj sib cais yarns feem ntau yog ua los ntawm hluavtaws polymers, xws li polyester los yog nylon, uas yog yaj thiab spun rau hauv fibers siv cov txheej txheem hu ua yaj spinning. Cov xov paj no paub txog lawv lub zog siab thiab ruaj khov, nrog rau lawv lub peev xwm los khi cov ntaub ntawv zoo.
Hauv cov ntsiab lus, cov xov paj kub melts sib cais yog ib hom xov paj siv hauv kev tsim cov ntaub ntawv tsis-woven los cais thiab khi cov txheej txheem ntawm cov khoom. Nws yog tsim los ntawm cov hluavtaws polymers uas yog yaj thiab spun rau hauv fibers thiab paub txog nws lub zog siab, ruaj khov, thiab muaj peev xwm sib txuas cov ntaub ntawv.
