Ifayibha yeViscose isekelwe kwiselulosi yendalo (i-pulp hectometer) imathiriyeli ekrwada, ijikeleza kwakhona emva kwesisombululo se-ester esityheli kwifayibha kunye nefayibha eselulosi ehlaziyiweyo.Kwimveliso ye-viscose fiber solidification process, dilute i-sodium hydroxide kunye ne-sulfuric acid kwi-reaction bath yokuqinisa ukwenza i-glauberite (i-sodium silicate powder).Ngokwembono yokubuyiswa kwenkunkuma yolwelo, umgangatho we-sodium sulfate efunyenwe kwinkunkuma engamanzi kwinkqubo yokuveliswa kwesilika ye-viscose ulungile.Ingxelo yokuhlola umgangatho ibonisa ukuba inzuzo ye-viscose fiber ngemveliso ye-sodium sulfate yimveliso: ubumhlophe obuhle, umxholo wemveliso ephezulu, umxholo we-ion ye-chloride ephantsi, ixabiso eliphantsi lokuvelisa kunye nexabiso lokuthengisa eliguquguqukayo;Ukungalungi kwemveliso: ubungakanani bamasuntswana alungileyo, kulula ukwenza i-caking, ixabiso le-PH li-acidic.I-Viscose fiber nge-powder powder ifanelekile kwiglasi, iphepha kunye namanye amashishini asezantsi.
I-China ngumvelisi omkhulu wefayibha yemichiza kunye nomvelisi onamandla kuphuhliso.Kwiminyaka yakutshanje, umzi-mveliso wefayibha eselulose esetyenzisiweyo kwilizwe lethu ubukhulu becala yifayibha eyi-staple, enamandla okuvelisa malunga ne-5 yezigidi zeetoni.Ngokutsho manani Yuanming umgubo kushishino iqonga ulwazi likawonke, ukuveliswa sodium byproduct sulfate kushishino imichiza ifayibha akhawunti malunga nesiqingatha semveliso iyonke sodium byproduct sulfate kweli lizwe, leyo iphezulu kwiindidi ezininzi sodium byproduct sulfate ishishini. ngoku.
Ifayibha esisiseko yeViscose yeyefayibha yokuhlaziya yendalo eselulosi, kwaye umqhaphu kunye nefiber esisiseko yepolyester zezezi zinto zintathu ziphambili zokusonta umqhaphu ekrwada.Yenziwe nge-cellulose yendalo (i-pulp) njengeyona nto isisiseko ekrwada, ngokusebenzisa i-alkalination, ukuguga, i-sulfonation kunye nezinye iinkqubo zibe yi-soluble cellulose sulfonate, emva koko inyibilikiswe kwi-lye e-dilute ukwenza i-viscose, ngokujikeleza okumanzi kwaye yenziwe.
Ngokwezibalo, kwi-2021, i-fiber ye-viscose yaseChina yayiyi-4.031 yezigidi zeetoni, ukwanda kwe-1.93% xa kuthelekiswa no-2020. Ngokobude befiber, i-viscose fiber inokwahlulwa ibe yi-viscose staple fiber kunye ne-viscose filament.Kwi-2021, imveliso ye-viscose staple fiber yafikelela kwi-3.87 yezigidi zeetoni, kunye nokunyuka konyaka-ngonyaka we-2.12%;Imveliso ye-Viscose filament yayiyi-161,000 yeetoni, phantsi kwe-2.42% ngonyaka.
