Viscose faibha yakavakirwa pachisikigo cellulose (pulp hectometer) mbishi zvinhu, ichitenderera zvakare mushure meyero asidhi ester mhinduro mufayibha uye regenerated cellulose fiber.Mukugadzira viscose faibha solidification process, dilute sodium hydroxide uye sulfuric acid mune solidification bath reaction kuita glauberite (sodium silicate poda).Kubva pakuona kwekurasa kwemvura kupora, mhando yesodium sulfate yakadzoserwa kubva mumarara emvura mukugadzira viscose sirika kugadzirwa kwakanaka.Chirevo chekuongorora chehutano chinoratidza kuti zvakanakira viscose fiber by-product sodium sulfate zvigadzirwa ndezvi: kuchena kwakanaka, kugadzirwa kwepamusoro kwechigadzirwa, pasi chloride ion content, mutengo wakaderera wekugadzira uye mutengo wekutengesa unoshanduka;Kukanganisa kwechigadzirwa ndeichi: yakanaka particle size, iri nyore kugadzira, PH kukosha acidic.Viscose fiber by-chigadzirwa poda inokodzera girazi, pepa uye mamwe maindasitiri ezasi.
China ndiyo inogadzira makemikari fiber uye inogadzira yakasimba mukusimudzira.Mumakore achangopfuura, iyo yakadzokororwa cellulose fiber indasitiri munyika yedu inonyanya kufayibha, ine simba rekugadzira rinosvika mamirioni mashanu ematani.Zvinoenderana nehuwandu hweYuanming powder industry information public platform, kugadzirwa kwesodium byproduct sulfate mumakemikari fiber indasitiri inokwana hafu yehuwandu hwekugadzirwa kwesodium byproduct sulfate munyika, inova ndiyo yepamusoro-soro mumhando dzakawanda dzesodium byproduct sulfate indasitiri. parizvino.
Viscose staple fiber ndeyezve kugadzirwa patsva kwechisikigo cellulose, uye donje uye polyester staple fiber ndeye matatu makuru edonje anoruka zvinhu.Iyo inogadzirwa neyechisikigo cellulose (pulp) seyakanyanya mbishi zvinhu, kuburikidza nealkalination, kuchembera, sulfonation uye mamwe maitiro mu soluble cellulose sulfonate, yozonyungudika mu dilute lye kugadzira viscose, nekunyorova kuruka uye kugadzirwa.
Maererano nenhamba, muna 2021, China yeviscose fiber yakabuda yaiva mamiriyoni 4.031 emamiriyoni, kuwedzera kwe1.93% kana ichienzaniswa ne2020. Maererano nehurefu hwefiber, viscose fiber inogona kugoverwa kuva viscose staple fiber uye viscose filament.Muna 2021, kubudiswa kweviscose staple fiber kwakasvika mamiriyoni 3.87 emamiriyoni, nekuwedzera kwegore negore kwe2.12%;Kugadzirwa kweViscose filament kwaive 161,000 matani, pasi 2.42% gore negore.
