Fiber ea Viscose e thehiloe holim'a selulose ea tlhaho (pulp hectometer) e tala, e bilika hape ka mor'a tharollo ea ester e mosehla ho fiber le fiber e tsosolositsoeng ea selulose.Ho hlahisoeng ha viscose fiber solidification process, hlapolla sodium hydroxide le sulfuric acid ka karabelo ea ho hlapa ea solidification ho theha glauberite (sodium silicate powder).Ho ea ka pono ea ho hlaphoheloa ha metsi a litšila, boleng ba sodium sulfate bo fumanoeng ho tsoa ho litšila nakong ea tlhahiso ea silika ea viscose bo batla bo le ntle.Tlaleho ea tlhahlobo ea boleng e bontša hore melemo ea lihlahisoa tsa viscose fiber by-product sodium sulfate ke: bosoeu bo botle, lihlahisoa tse phahameng tsa lihlahisoa, lihlahisoa tse tlaase tsa chloride ion, theko e tlaase ea tlhahiso le theko e bonolo ea thekiso;Phoso ea sehlahisoa ke: boholo bo botle ba likaroloana, bo bonolo ho kaka, PH e na le asiti.Viscose fiber by-product powder e loketse khalase, pampiri le liindasteri tse ling tse tlase.
China ke mohlahisi e moholo oa fiber ea lik'hemik'hale le mohlahisi ea matla nts'etsopele.Lilemong tsa morao tjena, indasteri ea fiber ea selulose e nchafalitsoeng naheng ea rona haholo-holo ke fiber e tloaelehileng, e nang le matla a tlhahiso ea lithane tse ka bang limilione tse 5.Ho ea ka lipalo-palo tsa Yuanming powder tlhahisoleseding sethaleng sa sechaba, tlhahiso ea sodium byproduct sulfate indastering ea lik'hemik'hale fiber e etsa hoo e ka bang halofo ea kakaretso ea tlhahiso ea sodium byproduct sulfate naheng, e leng eona e phahameng ka ho fetisisa mefuteng e mengata ea sodium byproduct sulfate indasteri. hajoale.
Viscose staple fiber ke ea fiber e nchafatsang ea selulose ea tlhaho, 'me fiber ea k'hothone le polyester ke tsa lisebelisoa tse tharo tse kholo tsa k'hothone tse ohlang.E entsoe ka selulose ea tlhaho (pulp) e le thepa ea motheo e tala, ka alkalination, botsofali, sulfonation le mekhoa e meng ho kena ka har'a cellulose sulfonate e qhibilihang, ebe e qhibiliha ka sesepa sa sesepa ho etsa viscose, ka ho ohla metsi le ho etsoa.
Ho ea ka lipalo-palo, ka 2021, tlhahiso ea China ea viscose fiber e ne e le lithane tse limilione tse 4.031, keketseho ea 1.93% ha e bapisoa le 2020. Ho ea ka bolelele ba fiber, fiber ea viscose e ka aroloa ka viscose staple fiber le viscose filament.Ka 2021, tlhahiso ea fiber ea viscose e fihlile ho lithane tse limilione tse 3.87, ka keketseho ea selemo le selemo ea 2.12%;Tlhahiso ea li-viscose filament e ne e le lithane tse 161,000, ho theoha ka 2.42% selemo le selemo.
