Fibre fibre ishingiye kubintu bisanzwe bya selile (pulp hectometer) yibikoresho fatizo, byongera kuzunguruka nyuma yumuti wa ester acide yumuhondo muri fibre hamwe na fibre selile.Mu gukora fibre fibre yogukomera, koresha hydroxide ya sodium na acide sulfurike mu kwiyuhagira kwiyuhagira kugirango ube glauberite (ifu ya sodium silike).Urebye imyanda isubirana, ubwiza bwa sodium sulfate yagaruwe mumazi yimyanda mugihe cyo kubyara silike ya viscose nibyiza.Raporo y'ubugenzuzi bufite ireme yerekana ko ibyiza bya fibre fibre ikomoka ku bicuruzwa bya sodium sulfate ari: umweru mwiza, ibicuruzwa byinshi, ibirungo bya chloride nkeya, igiciro gito cy'umusaruro n'igiciro cyoroshye cyo kugurisha;Ibibi byibicuruzwa ni: ingano yingirakamaro, byoroshye guteka, PH agaciro acide.Ifu ya Viscose fibre yibicuruzwa ikwiranye nikirahure, impapuro nizindi nganda zo hepfo.
Ubushinwa n’umusemburo ukomeye wa fibre chimique nuwukora cyane mu iterambere.Mu myaka yashize, inganda za fibre selile ikoreshwa mu gihugu cyacu ni fibre nyamukuru, ifite umusaruro wa toni zigera kuri miliyoni 5.Dukurikije imibare y’inganda za Yuanming zerekana amakuru ku mbuga rusange, umusaruro wa sodium byproduct sulfate mu nganda zikora fibre chimique zingana na kimwe cya kabiri cy’umusaruro wa sodium byproduct sulfate mu gihugu, kikaba ari cyo kinini mu bwoko bwinshi bwa sodium byproduct sulfate Kuri ubu.
Viscose staple fibre ni iy'ibibyimba bishya bya selile isanzwe, naho ipamba na polyester staple fibre ni bitatu byingenzi byingenzi bizunguruka.Ikozwe muri selile karemano (pulp) nkibikoresho fatizo fatizo, binyuze muri alkalination, gusaza, sulfonation nibindi bikorwa muri selile sulfonate ya elegitoronike, hanyuma igashonga muri lye dilute kugirango ikore viscose, mukuzunguruka no gukora.
Nk’uko imibare ibigaragaza, mu 2021, Ubushinwa bwasohotse muri toni miliyoni 4.031, bwiyongereyeho 1,93% ugereranije na 2020. Ukurikije uburebure bwa fibre, fibre viscose ishobora kugabanywamo fibre staple fibre na viscose.Mu 2021, umusaruro wa fibre staple fibre wageze kuri toni miliyoni 3.87, umwaka ushize wiyongereyeho 2,12%;Umusemburo wa Viscose wakozwe ni toni 161.000, wagabanutseho 2,42% umwaka ushize.
