Embonini yamaphepha, i-Fiber Morphology ingenye yezinto ezibalulekile ezanquma izakhiwo zePulp nekhwalithi yokugcina yamaphepha. I-Fiber Morphoology ehlanganisa ubude bemicu ephakathi, isilinganiso sokuqina kodonga lwe-fiber cell kububanzi be-cell (okubhekiselwa khona njengesilinganiso sodonga-to-cavity), kanye nenani lama-heteroctys angewona ama-heteroc. Lezi zinto zixhumana nomunye, futhi ngokuhlanganyela zithinte amandla ebhondi ye-pulp, ukusebenza kwamapheko, ukukopisha ukusebenza, kanye namandla, ukuqina kanye nekhwalithi ephelele yephepha.
1) Ubude obumaphakathi wefiber
Ubude obuphakathi bemicu bungenye yezinkomba ezibalulekile zekhwalithi ye-pulp. Imicu emide iklama amaketanga wenethiwekhi amade ku-pulp, esiza ukuthuthukisa amandla webhondi nezindawo ezishubile zephepha. Lapho ubude bemicu obuphakathi benyuka, inani lamaphuzu ahlanganisiwe phakathi kwemicu likhuphuka, livumela iphepha ukuthi lisakaze kangcono ukucindezelwa lapho libhekiswe emandleni angaphandle, ngaleyo ndlela lithuthukisa amandla nokuqina kwephepha. Ngakho-ke, ukusetshenziswa kwemicu yobude obude, njenge-pulp ye-spruce njengezinto zokupakisha, iphepha lokuphrinta nokunye.
2) isilinganiso sokuqina kodonga lwe-fiber cell ku-cell cavity ububanzi (isilinganiso sodonga-to-cavity)
Isilinganiso sodonga-to-cavity kungenye into ebalulekile ethinta izakhiwo ze-pulp. Isilinganiso se-Low Wall-to-Cavity sisho ukuthi udonga lweseli lwe-fiber luncane futhi umgodi weseli lukhulu, ukuze imicu ephutselweni kanye nenqubo yokuphamba kulula ukuyithola amanzi futhi ithambile, ilungele ukucolisiswa kwemicu, ukuhlakazeka nokuhlangana. Ngasikhathi sinye, imicu emincane ebiyelwe ngodonga ihlinzeka ukuguquguquka okungcono nokusongekayo lapho kwakha iphepha, okwenza iphepha lifaneleke kakhulu ukucubungula okuyinkimbinkimbi nezinqubo zokwakha. Ngokuphambene, imicu enezilinganiso eziphezulu zodonga-to-cavity ingaholela ekutheni kube nzima kakhulu, iphepha le-brittle, elingalungile ekucutshungweni nasekusetshenzisweni okulandelayo.
3) Okuqukethwe kwama-heterocytes angewona ama-fibrous kanye nezinqwaba zefayibha
Amaseli angawona ama-fibrous kanye nezinqwaba zefayibha ku-pulp yizici ezingezinhle ezithinta ikhwalithi yephepha. Lokhu kungcoliswa ngeke kunciphise ubumsulwa nobunye be-pulp, kepha futhi nasezinhlotsheni ezinamaphepha ukwakha ama-knots kanye neziphambeko, okuthinta ubushelelezi namandla ephepha. Ama-heterocytes angavuleki angewona ama-fibrous angavela ezingxenyeni ezingahambisani namagxolo, ama-resin kanye nezinsini ezibonakalayo ezingavuthiwe, ngenkathi ama-fiber aggrensi afakwa ngenxa yokwehluleka kwenqubo eluhlaza. Ngakho-ke, lokhu kungcola kufanele kususwe ngangokunokwenzeka ngesikhathi senqubo yokuphamba ukwenza ngcono ikhwalithi ye-pulp kanye nesivuno sephepha.
