Iphepha elisetyenziswe kwinkampani yethuiibhokisi zesonka,iibhokisi zepizzakunye nezinyeiibhokisi zokupakisha ukutyaiveliswa ngowona buchwepheshe buphambili bokwenza iphepha, ukubonelela undwendwe ngalunye ngezona mveliso zisemgangathweni
Ngexesha le-Western Han Dynasty (206 BC), i-China yayisele inephepha, kwaye kunyaka wokuqala we-Yuanxing (105) kwi-Eastern Han Dynasty, uCai Lun waphucula ukwenza iphepha.Usebenzisa amaxolo, intloko yehempe, ilaphu, umnatha wokuloba kunye nezinye izinto ezikrwada ukwenza iphepha ngenkqubo yokucofa, ukubhuqa, ukuqhotsa, ukubhaka, njalo njalo, eyimvelaphi yephepha langoku.Olu hlobo lwephepha, imathiriyeli ekrwada kulula ukuyifumana, inexabiso eliphantsi kakhulu, umgangatho nawo uphucukile, kwaye ngokuthe ngcembe isetyenziswa ngokubanzi.Ukukhumbula impumelelo kaCai Lun, izizukulwana ezilandelayo zalibiza eli phepha ngokuthi “iphepha leCai Hou”.
Iphepha liyicrystallization yamava exesha elide kunye nobulumko babantu baseTshayina abasebenza.Iphepha yimveliso yefiber efana neshiti esetyenziselwa ukubhala, ukuprinta, ukupeyinta okanye ukupakisha.Ngokuqhelekileyo, yenziwe ngokunqunyanyiswa kwamanzi kwimicu yezityalo edibeneyo, edityaniswe kwi-net, iqale iphelelwe ngamanzi, kwaye icinezelwe kwaye yomiswe.I-China lilizwe lokuqala ehlabathini ukwenza iphepha.
Ubugcisa bale mihla buhambela phambili ngokukhawuleza, yaye inkqubo yale mihla yokwenza iphepha iye yenziwa ngoomatshini.
I-Groundwood Pulp isebenzisa amandla okusila oomatshini ukufumana i-fiber yomthi, ekwabizwa ngokuba yi-pulp yomatshini, enokwahlulwa ibe yipulp yomatshini ngokubanzi, i-pulp yomatshini esulungekileyo, ipulp ye-thermomechanical, njl.
I-pulp yekhemikhali isebenzisa iindlela zekhemikhali ukwahlula iintsinga kwi-lignin ukufumana imicu yomthi, enokwahlulwa kwakhona ibe yi-soda pulp, i-sulfite pulp, kunye ne-sulfate pulp.
I-pulp ye-semichemical (i-Semichemical Pulp) Ukudibanisa iindlela zomatshini kunye neekhemikhali zokutsalwa kweekhemikhali, zinokwahlulwa kwakhona zibe yi-pulp ye-semi-chemical engathathi hlangothi, i-pulp ye-soda ebandayo, i-pulp ye-chemical mechanical, njl.
