Indastering ea pampiri, fiber morphology ke e 'ngoe ea lintlha tsa bohlokoa tse khethollang thepa ea makhasi le boleng ba pampiri ea ho qetela. Fiber morphology e akaretsa bolelele bo tloaelehileng ba likhoele, karo-karolelano ea botenya ba lerako la fiber ho bophara ba sele (e bitsoang karo-karolelano ea lebota ho isa ho cavity), le bongata ba li-heterocyte tse se nang li-fibrous le li-bundle tsa fiber ka har'a makhasi. Lintlha tsena li sebelisana, 'me li ama ka kopanelo matla a tlamahano ea makhasi, katleho ea ho felloa ke metsi, ts'ebetso ea ho kopitsa, hammoho le matla, ho tiea le boleng ba kakaretso ba pampiri.
1) Karolelano ea bolelele ba fiber
Karolelano ea bolelele ba likhoele ke e 'ngoe ea matšoao a bohlokoa a boleng ba makhasi. Likhoele tse telele li etsa liketane tse telele tsa marang-rang ka har'a makhasi, tse thusang ho matlafatsa matla a tlamahano le thepa e tsitsitseng ea pampiri. Ha bolelele ba likhoele bo ntse bo eketseha, palo ea lintlha tse kopantsoeng pakeng tsa likhoele li eketseha, e leng se lumellang pampiri hore e ntlafatse khatello ea kelello ha e le tlas'a matla a ka ntle, kahoo e ntlafatsa matla le ho tiea ha pampiri. Ka hona, ts'ebeliso ea likhoele tse telele tsa bolelele bo bolelele, joalo ka spruce coniferous pulp kapa k'hothone le makhasi a line, li ka hlahisa matla a phahameng, ho thatafala ha pampiri, lipampiri tsena li loketse ho sebelisoa ha ho hlokahala thepa e phahameng ea 'mele ea ketsahalo eo, joalo ka thepa ea ho paka, pampiri ea khatiso joalo-joalo.
2) Karo-karolelano ea botenya ba lerako la fiber ho bophara ba selefouno (lebota-to-cavity ratio)
Karo-karolelano ea lebota-to-cavity ke ntlha e 'ngoe ea bohlokoa e amang thepa ea pulp. Karo-karolelano e ka tlaase ea lebota ho ea ho cavity e bolela hore lerako la sele ea fiber le batla le le tšesaane 'me sebaka sa sele se seholoanyane, e le hore likhoele tse ka har'a pulping le ho etsa pampiri li nolofalloe ho monya metsi le ho nolofatsa, ho thusa ho ntlafala ha likhoele, ho hasana. le ho hohlana. Ka nako e ts'oanang, likhoele tse tšesaane tse nang le marako li fana ka phetoho e ntle le ho phutholoha ha ho etsoa pampiri, ho etsa hore pampiri e tšoanelehe haholoanyane bakeng sa ts'ebetso e rarahaneng le mekhoa ea ho etsa. Ka lehlakoreng le leng, likhoele tse nang le likarolo tse phahameng tsa lebota-to-cavity li ka lebisa pampiring e thata ka ho fetisisa, e brittle, e sa lokelang ho sebetsa le ho sebelisoa ka mor'a moo.
3) Likahare tsa li-heterocyte tse se nang fibrous le li-fiber bundles
Lisele tse se nang li-fibrous le li-fiber bundles ka har'a makhasi ke lintlha tse mpe tse amang boleng ba pampiri. Litšila tsena li ke ke tsa fokotsa feela bohloeki le ho tšoana ha makhasi, empa hape le ka mokhoa oa ho etsa pampiri ho etsa mafito le mefokolo, e amang boreleli le matla a pampiri. Li-heterocyte tse se nang li-fibrous li ka 'na tsa tsoa ho likarolo tse se nang fiber tse kang makhapetla, resin le marenene ka lihlahisoa tse tala, ha li-fiber bundles e le li-fiber aggregates tse entsoeng ka lebaka la ho hlōleha ha thepa e tala ho ikarola ka ho lekaneng nakong ea ho lokisetsa. Ka hona, litšila tsena li lokela ho tlosoa ka hohle kamoo ho ka khonehang nakong ea ts'ebetso ea pulping ho ntlafatsa boleng ba makhasi le tlhahiso ea pampiri.
