Yog vim li cas vim li cas cov ntaub so ntswg yuav plam hmoov yog tias daim ntawv yog ua los ntawm fibers ntawm txawv lengths interwoven ua ke. Thaum lub sij hawm tsim thiab ua cov ntawv, cov fibers me me qee zaum khiav tawm, tsim cov ntawv hmoov. Cov khoom tsim los ntawm cov txheej txheem papermaking zoo tshaj plaws, cov cuab yeej siv siab heev, thiab cov ntaub ntawv zoo zoo muaj cov hmoov ntawv tsawg dua, uas txhais tau hais tias cov khoom zoo dua qub, cov hmoov ntawv tsawg dua. Yog li ntawd, peb tuaj yeem txiav txim siab qhov zoo ntawm daim ntawv raws li tus nqi ntawm cov ntawv hmoov.
Qee cov neeg ntseeg tias cov ntawv softer, cov hmoov ntau dua, tab sis qhov tseeb, nws tsis yog. Yog vim li cas rau kev tsim cov ntawv hmoov muaj cov txheej txheem ntawm cov txheej txheem nyuaj xws li pulp, additives, thiab wrinkling, yog li nws tsis tas yuav softer daim ntawv, ntau cov ntawv hmoov muaj. Tab sis feem ntau hais lus, los ntawm kev sib piv, rau cov khoom siv tib yam, cov ntawv softer, cov ntawv hmoov ntau yuav muaj.
