Kupaka thonje, silika ndi ulusi wopangidwa

Ngakhale kuti ulusi wina wachilengedwe monga thonje ndi silika uli ndi zonyansa zomwe zimakhala zosavuta kuchotsa kusiyana ndi zomwe zimachitika muubweya, ndizofunikirabe kuzipukuta kuti zitsimikizidwe kuti bleaching yunifolomu, kupaka utoto ndi kumaliza komanso kupititsa patsogolo kunyowa kwawo ndi kuyamwa.

Thonje likhoza kukhala ndi 4-12% ndi zonyansa zolemera mu mawonekedwe a sera, mapuloteni, pectins, phulusa, ndi zinthu zina monga inki, hemicelluloses ndi kuchepetsa shuga.Mkhalidwe wa hydrophobic wa sera umapangitsa kuchotsedwa kwawo kukhala kovuta poyerekeza ndi kuchotsa zonyansa zina.Kupangidwa kwa sera ya thonje kumapangidwa makamaka ndi unyolo wautali wautali (C₁₅ku C₃₃) mowa, ma asidi, ndi ma hydrocarbons komanso ma sterols ndi ma polyterpenes.Zitsanzo ndi monga gossypol (C₃₀H₆₁OH), stearic acid (C₁₇H₃₅COOH), ndi glycerol.Ndizochepa zomwe zimadziwika za kapangidwe ka mapuloteni, ndipo ma pectins amapezeka ngati methyl ester ya poly-D-galacturonic acid.Phulusa ndi chisakanizo cha mankhwala achilengedwe (makamaka sodium, potaziyamu, magnesium ndi calcium salt), pomwe zonyansa zina zimasiyana mosiyanasiyana koma zimasinthidwa mosavuta ndi hydrolyzed ndikuchotsedwa pansi pamikhalidwe yowaza.

Kuchotsa bwino zonyansa mu thonje, makamaka sera, zimatheka powiritsa 3-6% sodium hydroxide kapena kuchepera pafupipafupi mu njira zochepetsera za calcium hydroxide (laimu) kapena sodium carbonate (soda phulusa).Kusankha koyenera kwa zida zothandizira nsalu mumtsuko wa alkaline ndikofunikira pakukwapula bwino.Izi zikuphatikizapo sequestering kapena chelating agents monga ethylenediaminetetraacetic acid (EDTA) kuti asungunuke zinthu zosasungunuka zomwe zimapezeka m'madzi olimba komanso zowonongeka monga anionic sodium lauryl sulfate yomwe imakhala ngati mankhwala otsukira, obalalitsa, ndi emulsifying agent kuchotsa unsaponifiable waxe.Ulusi wopangidwa umapakidwa ndi zinthu zocheperako monga sopo kapena zotsukira zomwe zimakhala ndi alkali pang'ono (monga 0.1-0.2% sodium carbonate).Zosakaniza za thonje/zopanga (monga thonje/poliyesitala) zimafuna kuchuluka kwa alkaline ndi mikhalidwe yapakatikati pakati pa thonje ndi zonse zopangira kuti zikolole bwino.

Kupaka ulusi wa silika kumadziwikanso kuti degumming.Kukwapula kwa silika kwawunikiridwa mozama pokhudzana ndi njira za degumming ndi makina komanso kuzindikira zinthu zomwe zachotsedwa mu ulusi.Choyipa chachikulu chomwe chiyenera kuchotsedwa ku silika ndi protein sericin, yomwe imadziwikanso kuti chingamu, yomwe imatha kuchoka pa 17% mpaka 38% potengera kulemera kwa ulusi wa silika wosapukuta.Sericin yochotsedwa mu ulusi wa silika wagawidwa m'zigawo zinayi zomwe zimasiyana mu kapangidwe kake ka amino acid ndi mawonekedwe ake.Pali njira zisanu zochotsera ulusi wa silika: (a) kuchotsa ndi madzi, (b) kuwiritsa mu sopo, (c) kutsuka ndi alkalis, (d) kutulutsa ma enzymatic degumming ndi (e) kuchotsa madzi mu acidic solution.Kuwotcha mu sopo ndi njira yodziwika kwambiri yochotsera degumming.Zosiyanasiyana za sopo ndi zosinthidwa zosinthidwa zimapereka milingo yosiyana ya kuyeretsedwa kwa ulusi wa silika.Ngakhale pali njira zambiri zodziwira kuchuluka kwa ulusi wa silika, njira zochulukira zochotsera sericin ndi njira zomwe amachotsera sizinapangidwe komanso kuperekedwa.

Zonyansa zomwe zimapezeka mu ulusi wopangidwa ndi mafuta ndi zopota zopota zomwe zimagwiritsidwa ntchito popota, kuluka ndi kuluka.Izi zitha kuchotsedwa mumikhalidwe yocheperako kuposa zonyansa za thonje ndi silika.scouring solutions for synthetic fibers amakhala ndi anionic kapena nonionic detergents okhala ndi sodium carbonate kapena ammonia;Kutentha kwa ulusi umenewu nthawi zambiri kumakhala 50-100 ° C.
