Zotsatira za fiber morphology pazamkati ndi khalidwe

M'makampani opanga mapepala, fiber morphology ndi chimodzi mwazinthu zazikulu zomwe zimatsimikizira zamkati ndi mtundu womaliza wa pepala. Fiber morphology imaphatikizapo kutalika kwa ulusi, chiŵerengero cha makulidwe a fiber cell khoma mpaka ma cell awiri (otchedwa khoma-to-cavity ratio), ndi kuchuluka kwa ma heterocyte opanda fibrous ndi mitolo ya ulusi mu zamkati. Zinthu izi zimalumikizana wina ndi mzake, ndipo zimakhudzanso mphamvu ya mgwirizano wa zamkati, kuchepa kwa madzi m'thupi, kukopera ntchito, komanso mphamvu, kulimba ndi khalidwe lonse la pepala.

1) Avereji ya utali wa fiber
Utali wapakati wa ulusi ndi chimodzi mwa zizindikiro zofunika kwambiri za ubwino wa ulusi. Ulusi wautali umapanga unyolo wautali wa netiweki mu ulusi, zomwe zimathandiza kulimbitsa mphamvu ya mgwirizano ndi mphamvu zomangika za pepala. Utali wapakati wa ulusi ukawonjezeka, kuchuluka kwa mfundo zolukana pakati pa ulusi kumawonjezeka, zomwe zimathandiza kuti pepalalo lifalikire bwino likakumana ndi mphamvu zakunja, motero kulimbitsa mphamvu ndi kulimba kwa pepalalo. Chifukwa chake, kugwiritsa ntchito ulusi wautali wapakati, monga ulusi wa spruce coniferous kapena ulusi wa thonje ndi nsalu, kungapangitse kuti pepala likhale lolimba kwambiri, ndipo mapepalawa ndi oyenera kugwiritsidwa ntchito pofunikira zinthu zakuthupi, monga zinthu zopakira, mapepala osindikizira ndi zina zotero.
2) Chiyerekezo cha makulidwe a fiber cell khoma mpaka cell cavity diameter (khoma-to-cavity ratio)
Chiŵerengero cha khoma-to-cavity ndi chinthu china chofunikira chomwe chimakhudza zamkati. Chiŵerengero chochepa cha khoma-to-cavity chimatanthawuza kuti khoma la selo la fiber ndilochepa kwambiri ndipo khungu la selo ndilokulirapo, kotero kuti ulusi mu pulping ndi kupanga mapepala zimakhala zosavuta kuyamwa madzi ndi kufewetsa, zomwe zimathandizira kukonzanso kwa ulusi, kufalikira ndi kuphatikizika. Panthawi imodzimodziyo, ulusi wokhala ndi mipanda yopyapyala umapereka kusinthasintha bwino komanso kupindika popanga mapepala, zomwe zimapangitsa kuti pepala likhale loyenera kwambiri pokonza ndi kupanga njira. Mosiyana ndi zimenezi, ulusi wokhala ndi makoma a khoma-to-cavity ukhoza kupangitsa pepala lolimba kwambiri, losasunthika, lomwe silingagwirizane ndi kukonzanso ndi kugwiritsira ntchito.
3) Kuchuluka kwa ma heterocyte osalimba ndi ma fiber bundles
Maselo osakhala ndi ulusi ndi ma ulusi m'mapepala ndi zinthu zoipa zomwe zimakhudza ubwino wa pepala. Zonyansa zimenezi sizingochepetsa kuyera ndi kufanana kwa mapepala, komanso njira yopangira mapepala kuti apange mfundo ndi zolakwika, zomwe zimakhudza kusalala ndi mphamvu ya pepala. Ma heterocyte osakhala ndi ulusi angachokere ku zinthu zopanda ulusi monga makungwa, utomoni ndi chingamu mu zinthu zopangira, pomwe ma ulusi ndi ma fiber aggregates omwe amapangidwa chifukwa cha kulephera kwa zinthu zopangira kugawanika mokwanira panthawi yokonzekera. Chifukwa chake, zonyansa izi ziyenera kuchotsedwa momwe zingathere panthawi yopangira mapepala kuti ziwongolere ubwino wa mapepala ndi kuchuluka kwa mapepala.
