Viscose fiber yog raws li ntuj cellulose (pulp hectometer) raw cov ntaub ntawv, spinning dua tom qab cov daj acid ester tov rau hauv fiber thiab regenerated cellulose fiber.Nyob rau hauv kev tsim cov viscose fiber ntau solidification txheej txheem, dilute sodium hydroxide thiab sulfuric acid nyob rau hauv lub solidification da dej tshuaj tiv thaiv rau daim ntawv glauberite (sodium silicate hmoov).Los ntawm qhov kev xav ntawm cov kua khib nyiab rov qab, qhov zoo ntawm sodium sulfate rov qab los ntawm cov kua khib nyiab hauv cov txheej txheem ntawm viscose txhob lo lo ntxhuav yog qhov zoo.Daim ntawv tshaj tawm kev soj ntsuam zoo qhia tau hais tias qhov zoo ntawm viscose fiber ntau los ntawm cov khoom siv sodium sulfate yog: zoo whiteness, siab cov ntsiab lus, cov ntsiab lus chloride ion tsawg, cov nqi tsim khoom tsawg thiab cov nqi muag khoom yooj yim;Qhov tsis zoo ntawm cov khoom yog: zoo particle loj, yooj yim rau caking, PH nqi acidic.Viscose fiber ntau los ntawm cov khoom siv hmoov yog tsim rau iav, ntawv thiab lwm yam kev lag luam downstream.
Tuam Tshoj yog ib lub chaw tsim khoom loj ntawm cov tshuaj fiber ntau thiab cov neeg tsim khoom muaj zog hauv kev txhim kho.Nyob rau hauv xyoo tas los no, kev lag luam siv cellulose fiber ntau hauv peb lub teb chaws yog cov khoom siv fiber ntau, nrog rau kev tsim khoom muaj peev xwm txog li 5 lab tons.Raws li kev txheeb cais ntawm Yuanming hmoov kev lag luam ntaub ntawv xov xwm pej xeem platform, zus tau tej cov sodium byproduct sulfate nyob rau hauv tshuaj fiber kev lag luam suav txog li ib nrab ntawm tag nrho cov khoom ntawm sodium byproduct sulfate nyob rau hauv lub teb chaws, uas yog lub siab tshaj plaws nyob rau hauv ntau yam ntawm sodium byproduct sulfate kev lag luam. tam sim no.
Viscose staple fiber belongs rau cov khoom siv fiber ntau ntawm cov cellulose, thiab paj rwb thiab polyester staple fiber yog peb cov paj rwb loj spinning raw khoom.Nws yog tsim los ntawm ntuj cellulose (pulp) raws li cov khoom siv raw, los ntawm alkalination, kev laus, sulfonation thiab lwm yam txheej txheem rau hauv soluble cellulose sulfonate, tom qab ntawd yaj hauv dilute lye los ua viscose, los ntawm ntub spinning thiab ua.
Raws li kev txheeb cais, xyoo 2021, Tuam Tshoj tus viscose fiber ntau tso tawm yog 4.031 lab tons, nce 1.93% piv nrog rau xyoo 2020. Raws li qhov ntev fiber ntau, viscose fiber ntau tuaj yeem muab faib ua viscose staple fiber thiab viscose filament.Hauv xyoo 2021, cov khoom tsim tawm ntawm viscose staple fiber ntau tau mus txog 3.87 lab tons, nrog rau kev nce xyoo ntawm 2.12%;Viscose filament ntau lawm yog 161,000 tons, nqis 2.42% xyoo-rau-xyoo.
