Ma'anar rini mai amsawa
Rini mai amsawa: Rini mai amsawa, wanda kuma aka sani da rini mai amsawa, nau'in rini ne da ke amsa zaruruwa yayin rini.Irin wannan nau'in kwayoyin rini yana ƙunshe da ƙungiyar da za ta iya amsawa ta hanyar sinadarai tare da fiber.A lokacin rini, rini yana amsawa da zaren, yana samar da haɗin gwiwa tsakanin su biyun kuma yana yin gaba ɗaya, wanda ke inganta saurin wankewa da shafa.
Rini masu amsawa sun ƙunshi rini na iyaye, ƙungiyoyi masu haɗawa da ƙungiyoyi masu amsawa.Rini precursor yana da azo, anthraquinone, phthalocyanine tsarin, da dai sauransu. Mafi na kowa reactive kungiyoyin su ne chlorinated junsanzhen (X-nau'in da K-type), vinyl sulfone sulfate (KN-type) da biyu-reactive kungiyar (M-type).Kwayoyin rini masu amsawa sun ƙunshi ƙungiyoyi masu aiki da sinadarai, waɗanda za su iya amsawa tare da auduga, ulu da sauran zaruruwa a cikin maganin ruwa don samar da haɗin gwiwa na gama gari, ta yadda masana'anta da aka gama rini suna da saurin wankewa.
Rini masu amsawa suna narkewa cikin ruwa kuma suna iya haɗawa tare da zaruruwan cellulose.Yana da launi mai haske, kyakkyawan aikin daidaitawa, yana iya rufe wasu lahani, kuma yana da saurin sabulu mai kyau.Duk da haka, yawancin rini masu amsawa ba su da ƙarancin juriya ga bleaching chlorine kuma suna kula da acid da alkalis.Kula da saurin yanayi lokacin rini launuka masu haske.Rini mai amsawa na iya rina auduga, viscose, siliki, ulu, nailan da sauran zaruruwa.

Rarraba rini masu amsawa
Dangane da ƙungiyoyin masu aiki daban-daban, ana iya raba rini masu amsawa zuwa nau'i biyu: nau'in triazene na simmetric da nau'in vinyl sulfone.
Nau'in triazene na simmetric: A cikin irin wannan nau'in rini mai amsawa, yanayin sinadarai na zarra na chlorine mai amsawa ya fi aiki.A lokacin rini, ana maye gurbin ƙwayoyin chlorine da fibers cellulose a cikin matsakaici na alkaline kuma su zama ƙungiyoyi masu barin.Halin da ke tsakanin rini da fiber cellulose shine yanayin maye gurbin bimolecular nucleophilic.
Nau'in Vinyl sulfone: Ƙungiyar mai amsawa da ke cikin wannan nau'in rini mai amsawa shine vinyl sulfone (D-SO2CH = CH2) ko β-hydroxyethyl sulfone sulfate.A lokacin rini, β-hydroxyethyl sulfone sulfate an kawar da shi a cikin matsakaiciyar alkaline don samar da rukunin vinyl sulfone, wanda sannan aka haɗa shi da fiber cellulose kuma ya sami ƙarin amsawar nucleophilic don samar da haɗin gwiwa.
Na sama nau'i biyu na rini mai amsawa sune manyan rinayen amsawa waɗanda suka fi girma a duniya.Domin inganta ƙimar daidaita rini masu amsawa, an shigar da ƙungiyoyi biyu masu amsawa cikin ƙwayoyin rini a cikin 'yan shekarun nan, waɗanda ake kira rini mai amsawa dual.
