Hauv kev lag luam daim ntawv, fiber morphology yog ib qho ntawm cov ntsiab lus tseem ceeb txiav txim siab rau cov khoom thiab cov ntawv kawg zoo. Fiber morphology encompasses qhov nruab nrab ntev ntawm fibers, piv txwv ntawm fiber ntau heterocytes thiab fiber ntau pob hauv lub pulp. Cov xwm txheej no sib cuam tshuam nrog txhua lwm yam, thiab ua ke cuam tshuam rau txoj kev sib txuas lus ntawm lub zog ntawm lub zog ntawm lub zog, luam tawm kev ua tau zoo, ua kom muaj zog, kev ua tau zoo thiab tag nrho cov ntawv.
1) Qhov ntsuas nruab nrab fiber ntau
Qhov nruab nrab ntev ntawm fibers yog ib qho ntawm cov ntsuas tseem ceeb ntawm pulp zoo. Ntev zog ua tiav cov saw ntev ntev hauv pulp, uas pab txhim kho txoj hlua khi thiab lub zog tensile ntawm cov ntawv. Thaum nruab nrab ntev ntawm cov fibers nce, tus naj npawb ntawm cov ntsiab lus cuam tshuam ntawm cov fibers nce ntxiv, yog li txhim kho lub zog thiab tawv ntawm daim ntawv. Yog li ntawd, kev siv ntawm qhov ntev ntev ntev fibers, xws li cov ntaub qhwv tshiab, cov ntaub ntawv thiab cov ntaub pua tsev tsim nyog rau kev siv hauv lub zog ntawm lub sijhawm, xws li ntim cov ntaub ntawv, luam ntawv thiab lwm yam.
2) Tus piv ntawm fiber ntau phab ntsa tuab rau Cell Nineity Diam (phab ntsa-rau-kab noj hniav diam)
Phab ntsa-rau-kab noj hniav sib piv yog lwm qhov tseem ceeb cuam tshuam cuam tshuam rau cov khoom siv pulp. Txo phab ntsa-rau-kab noj hniav sib piv txhais tau tias cov txheej txheem fiber ntau dua, yog li cov kab noj hniav yooj yim dua, yog li cov kab mob ntawm tes yooj yim dua, yog li cov kab mob ntawm tes yooj yim dua, yog li cov kab mob ntawm tes yooj yim dua, yog li cov kab mob ntawm tes yog qhov ua kom haum rau cov fibers, dispersion thiab intertwining. Nyob rau tib lub sijhawm, cov falled nyias nyias muaj zog muab cov ntawv yooj yim dua thiab cov ntawv sau, ua cov ntawv sau ua kom haum thiab cov txheej txheem. Nyob rau hauv kev sib piv, fibers nrog cov phab ntsa siab-rau-kab noj sib piv tuaj yeem ua rau cov ntawv nyuaj heev, cov ntawv loj, uas tsis zoo rau kev ua tiav thiab siv.
3) Cov ntsiab lus ntawm tsis-fibrous heterocytes thiab fiber bundles
Cov tsis muaj fibroous hlwb thiab fiber ntau cov pob hauv lub pulp yog qhov tsis zoo cuam tshuam rau cov ntawv zoo. Cov impurities no yuav tsis tsuas yog txo cov kev coj dawb huv thiab kev sib txawv ntawm cov pemp, tab sis kuj nyob rau qhov tsis xws luag, cuam tshuam rau lub smoothness thiab lub zog ntawm daim ntawv. Tsis-fibrocess heterocytes yuav tshwm sim los ntawm cov tawv nqaij tsis muaj fiber ntau, thaum cov pos hniav fiber ntau, thaum cov pos hniav fiber ntau, thaum cov pos hniav fiber ntau, thaum cov pos hniav uas muaj fiber ntau, thaum cov khoom siv fiber ntau, thaum cov pos hniav uas muaj fiber ntau los ua kom tsis muaj kev tshem tawm thaum lub sijhawm npaj. Yog li no, cov impurities no yuav tsum tau muab tshem tawm kom ntau li ntau tau thaum lub sij hawm pulping los txhim kho pulp zoo thiab daim ntawv tawm los.
