Cov fibers me me qee zaum dhau mus, thiab ntawv yog tsim thiab ua tiav los ntawm kev sib tshuam fibers ntawm qhov ntev sib txawv. Daim ntawv hmoov. Cov txheej txheem ua ntawv yog cov khoom siv zoo thiab cov khoom siv raw ua cov hmoov ntawv tsawg dua, uas txhais tau hais tias cov khoom zoo dua qub, cov hmoov ntawv tsawg dua. Yog li ntawd, qhov zoo ntawm daim ntawv tuaj yeem txiav txim siab raws li tus nqi ntawm cov ntawv hmoov. Thaum siv, talc hmoov yog ib qho yooj yim mus poob tawm, uas yog feem ntau hu ua "poob hmoov".
Qee tus 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.
Thaum xaiv daim ntawv tso quav tso quav, cov ntim sab nrauv yuav tsum tau kuaj xyuas ua ntej. Lub ntim ntim ntawm cov khoom yuav tsum zoo huv si thiab ruaj khov, tsis muaj kev puas tsuaj; Cov ntim khoom yuav tsum tau luam tawm nrog cov ntaub ntawv xws li cov chaw tsim khoom lub npe, hnub tsim khoom, qib khoom, tus lej siv, thiab tus lej tus qauv siv tu cev. Saib ntawm qhov pom ntawm daim ntawv, qhov saum npoo yuav tsum huv thiab tsis muaj qhov pom tseeb ntawm qhov tuag folds, qhov tsis xws luag, kev puas tsuaj, cov blocks nyuaj, nyom fibers, pulp clumps, thiab lwm yam ntawv tsis xws luag thiab impurities. Daim ntawv yuav tsum tsis txhob muaj cov plaub hau loj los yog hmoov thaum siv, thiab yuav tsum tsis muaj cov ntawv luam tawm nyob hauv daim ntawv.
