i-sulfur emnyama 240%yi-compound ephezulu ye-molecular equlethe i-sulfur engaphezulu, isakhiwo sayo sinee-disulfide bonds kunye nee-polysulfide bonds, kwaye ayizinzanga kakhulu. Ngokukodwa, i-polysulfide bond inoku-oxidized ibe yi-sulfur oxide yi-oxygen emoyeni phantsi kweemeko ezithile zobushushu kunye nokufuma, kwaye iqhubeke nokusebenzisana nee-molecule zamanzi emoyeni ukuvelisa i-sulfuric acid, ngaloo ndlela kunciphisa amandla entambo, ukubhitya kwefayibha, kwaye zonke iifayibha ziyabhitya zibe ngumgubo xa zinzima. Ngenxa yesi sizathu, ukuze kuncitshiswe okanye kuthintelwe umonakalo we-fiber brittleness emva kokudaywa ngedayi emnyama evulcanized, kufuneka kuqatshelwe la manqaku alandelayo:
① Ubungakanani bedayi emnyama evulcanized kufuneka bulinganiselwe, kwaye ubungakanani bedayi ekhethekileyo yemibala e-mercerized akufuneki budlule kwi-700g/ iphakheji. Ngenxa yokuba ubungakanani bedayi buphezulu, amathuba okuba buthathaka makhulu, kwaye ukukhawuleza kokudaya kuyancipha, kwaye ukuhlamba kunzima ngakumbi.
② Emva kokudaywa, kufuneka ihlanjwe ngokupheleleyo ukuze ingahlanjwa ngendlela engcolileyo, kwaye umbala odadayo kwintambo kulula ukuwubolisa ube yi-sulfuric acid ngexesha lokugcinwa, nto leyo eyenza ifayibha ibe buthathaka.
③ Emva kokudaywa, i-urea, i-soda ash kunye ne-sodium acetate mazisetyenziswe kunyango lokulwa nokuqhekeka kwesikhumba.
④ Intambo ibiliswa emanzini acocekileyo ngaphambi kokuba idaywe, kwaye izinga lokuqhekeka kwentambo edaywe emanzini acocekileyo lingcono kunele-lye emva kokuba idaywe.
⑤ Intambo kufuneka yomiswe ngexesha emva kokudaywa, kuba intambo emanzi kulula ukuyifudumeza kwinkqubo yenqwaba, ukuze umxholo wento yokulwa nokuqhekeka kwentambo unciphe, ixabiso le-pH linciphe, nto leyo engayivumeliyo ukuba iqhekeke. Emva kokomisa intambo, kufuneka ipholiswe ngokwemvelo, ukuze ubushushu bentambo bupakishwe ngaphambi kokuba buwele kubushushu begumbi. Ngenxa yokuba ayipholiswa emva kokuyomiswa kwaye ipakishwe kwangoko, ubushushu abulula ukusasazwa, nto leyo enyusa amandla okubola kwedayi kunye ne-asidi, nto leyo ebangela ukuba ifayibha ibe buthathaka.
⑥Ukukhethwa kweedayi ezimnyama ezichasene ne-brittle-sulphur, ezi dayi zongezwe kwi-formaldehyde kunye ne-chloroacetic acid xa kusenziwa, i-methyl-chlorine ebangela ukuba i-vulcanized anti-brittle-black iphume, ukuze ii-athomu ze-sulphur ezidityaniswe lula zibe yimeko eqinileyo yesakhiwo, enokuthintela i-oxidation yee-athomu ze-sulphur ukuvelisa i-asidi kunye ne-brittle fiber.
