I-Viscose fibre isekelwe ku-cellulose yemvelo (i-pulp hectometer) impahla eluhlaza, iphinde iphothwe ngemva kwesixazululo se-ester esiphuzi esine-asidi sibe yifayibha kanye nefayibha ye-cellulose evuselelwe.Ekukhiqizeni inqubo yokuqinisa i-viscose fibre solidification, hlambulula i-sodium hydroxide ne-sulfuric acid ekuphenduleni kokugeza okuqinile ukuze wenze i-glauberite (impushana ye-sodium silicate).Ngokombono wokuthola kabusha uketshezi olungcolile, ikhwalithi ye-sodium sulfate etholwe oketshezini olubi ngesikhathi sokukhiqizwa kukasilika we-viscose lihle uma kuqhathaniswa.Umbiko wokuhlolwa kwekhwalithi ubonisa ukuthi izinzuzo zemikhiqizo ye-viscose fiber by-product sodium sulfate yilezi: ubumhlophe obuhle, okuqukethwe komkhiqizo ophezulu, okuqukethwe kwe-ion ye-chloride ephansi, izindleko eziphansi zokukhiqiza kanye nentengo yokuthengisa eguquguqukayo;Ububi bomkhiqizo yilokhu: usayizi wezinhlayiyana ezinhle, ukwakheka kalula, i-PH value acidic.I-Viscose fiber by-product powder ifanele ingilazi, iphepha nezinye izimboni ezingaphansi komfula.
I-China ingumkhiqizi omkhulu we-chemical fiber kanye nomkhiqizi oqinile ekuthuthukisweni.Eminyakeni yamuva nje, imboni ye-cellulose fiber egaywe kabusha ezweni lethu iyi-fiber eyisisekelo, enekhono lokukhiqiza elingamathani ayizigidi ezi-5.Ngokwezibalo ze-Yuanming powder yesikhulumi solwazi sembonini yomphakathi, ukukhiqizwa kwe-sodium byproduct sulfate embonini yamakhemikhali e-fiber akhawunti cishe ingxenye yengqikithi yokukhiqizwa kwe-sodium byproduct sulfate ezweni, ephakeme kakhulu ezinhlotsheni eziningi zemboni ye-sodium byproduct sulfate. okwamanje.
I-Viscose staple fiber ingeye-fiber evuselelayo ye-cellulose yemvelo, kanti i-cotton ne-polyester staple fiber ingezinto ezintathu ezinkulu zokuphotha ukotini.Yenziwe nge-cellulose yemvelo (i-pulp) njengento eyisisekelo eluhlaza, ngokusebenzisa i-alkalination, ukuguga, i-sulfonation nezinye izinqubo zibe yi-soluble cellulose sulfonate, bese incibilika ku-lye ehlanjululwe ukwenza i-viscose, ngokuphotha okumanzi futhi yenziwe.
Ngokwezibalo, ngo-2021, i-viscose fibre ephumayo yaseChina yayingamathani ayizigidi ezingu-4.031, okuwukunyuka ngo-1.93% uma kuqhathaniswa no-2020. Ngokobude befayibha, i-viscose fiber ingahlukaniswa ibe i-viscose staple fiber kanye ne-viscose filament.Ngo-2021, ukukhishwa kwe-viscose staple fiber kwafinyelela amathani ayizigidi ezingu-3.87, ngokunyuka konyaka ngonyaka ngo-2.12%;Ukukhiqizwa kwe-Viscose filament kwaba amathani angu-161,000, phansi ngo-2.42% unyaka nonyaka.
