Mu nganda zimpapuro, fibre morphologie nimwe mubintu byingenzi bigena imiterere ya pulp nubwiza bwimpapuro zanyuma. Imiterere ya fibre ikubiyemo uburebure buringaniye bwa fibre, igipimo cyurukuta rwa fibre selile yuburebure na diameter ya selile (byitwa igipimo cyurukuta na cavity), hamwe nubunini bwa heterocytes idafite fibrous hamwe na fibre bundles muri pulp. Izi ngingo zikorana nizindi, kandi zifatanije zigira ingaruka kumubano wububiko bwa pulp, gukora umwuma, gukora kopi, kimwe nimbaraga, ubukana hamwe nubwiza bwimpapuro.
1) Impuzandengo ya fibre
Impuzandengo yuburebure bwa fibre nimwe mubimenyetso byingenzi byerekana ubwiza bwa pulp. Fibre ndende ikora urunigi rurerure mumurongo, ifasha kuzamura imbaraga zumubano hamwe nimiterere yimpapuro. Iyo impuzandengo yuburebure bwa fibre yiyongereye, umubare wibintu bifatanye hagati ya fibre uriyongera, bigatuma impapuro zishobora gukwirakwiza neza imihangayiko iyo ikorewe imbaraga ziva hanze, bityo bikazamura imbaraga nubukomezi bwimpapuro. Kubwibyo, gukoresha uburebure burebure buringaniye bwa fibre, nka spuce coniferous pulp cyangwa ipamba na pisine, birashobora gutanga imbaraga nyinshi, gukomera kwimpapuro, izi mpapuro zirakwiriye gukoreshwa mugukenera ibintu bifatika byumubiri byigihe, nk'ibikoresho byo gupakira, impapuro zo gucapa n'ibindi.
2) Ikigereranyo cyurukuta rwa fibre selile yububiko bwa diameter (urukuta-kuri-cavity ratio)
Ikigereranyo cyurukuta-kuri-cavity nikindi kintu cyingenzi kigira ingaruka kumiterere. Ikigereranyo cyo hasi kurukuta-cavity bivuze ko urukuta rwa fibre selile ruba ruto kandi urwobo rwakagari nini, kuburyo fibre mugikorwa cyo guhonda no gukora impapuro byoroshye gufata amazi no koroshya, bifasha gutunganya neza fibre, gutatanya no gufatanya. Muri icyo gihe, fibre yoroheje ifite uruzitiro rutanga uburyo bwiza bwo guhinduka no guhindagurika mugihe ukora impapuro, bigatuma impapuro zikwiranye no gutunganya no gukora ibintu bigoye. Ibinyuranyo, fibre ifite igipimo kinini cyurukuta-kuri-cavity irashobora kuganisha ku mpapuro zikomeye cyane, zimenetse, zidafasha gutunganya no gukoreshwa nyuma.
3) Ibiri muri heterocytes idafite fibrous na fibre bundles
Utugingo ngengabuzima tutari fibrous hamwe na fibre bundles muri pulp ni ibintu bibi bigira ingaruka kumiterere yimpapuro. Iyi myanda ntizagabanya gusa ubuziranenge nuburinganire bwimbuto, ahubwo no mubikorwa byo gukora impapuro kugirango bibe ipfundo nudusembwa, bigira ingaruka kumyizerere n'imbaraga zimpapuro. Heterocytes idafite fibrous irashobora guturuka mubintu bitari fibrous nkibishishwa, resin hamwe nishinya mubikoresho fatizo, mugihe imigozi ya fibre ni fibre igizwe na fibre iterwa no kunanirwa kw'ibikoresho fatizo gutandukana bihagije mugihe cyo kwitegura. Kubwibyo, iyi myanda igomba gukurwaho bishoboka mugihe cyogusunika kugirango ubwiza bwimbuto hamwe numusaruro wimpapuro.
