Irasa n'ubudodo, ifite isaro ryiza cyane irabagirana, ariko biroroshye kubyitaho kuruta ubudodo, kandi byoroshye kwambara. ”Kumva ibyifuzo nkibi, urashobora rwose gukeka iyi mpeshyi ikwiye - igitambaro cya triacetate.
Muriyi mpeshyi, imyenda ya triacetate hamwe nubudodo bwabo bumeze nkubudodo, ubukonje kandi bworoshye, hamwe nigitsina cyiza cyane cyashimishijwe nabamideri benshi.Fungura igitabo gito gitukura hanyuma ushakishe "acide triacetic", urashobora kubona inoti zirenga 10,000 kugirango dusangire.Ikirenzeho, umwenda ntusaba kwitabwaho cyane kugirango ugume neza, kandi urashobora kumera nku gihumbi.
Mu myaka yashize, triacetate yakunze kugaragara kumuhanda wa Marc Jacobs, Alexander Wang na Studiyo ya Acne.Nimwe mubigomba-kugira imyenda yimpeshyi nimpeshyi kubirango byinshi byingenzi kandi byibanze kumurongo wimyambarire myinshi.Ni ubuhe butumwa butatu?Birashobora kugereranywa rwose nubudodo nyabwo?Imyenda ya acide ya diacetike iruta aside triacetike?
01.Ni ubuhe butatu
Triacetate ni ubwoko bwa Acetate ya Cellulose (CA), ni fibre ya chimique ikozwe muri selile ya selile na synthesis.Tubivuze mu buryo bworoshe, ni ubwoko bwibiti bisanzwe nkibikoresho fatizo bya fibre yongeye gukoreshwa, ni ubwoko bushya bwa fibre karemano kandi yubuhanga buhanitse bwakozwe na Mitsubishi Corporation yu Buyapani.
02.Ni izihe nyungu za fibre triacetate?
Triacetate irazwi cyane, kubera ko ishobora gukoreshwa na silike ya tuteri, izwi nka "silk igihingwa cyogejwe".Triacetate ifite ububengerane busa na silike ya tuteri, ifite drape yoroshye, yoroshye cyane kandi itanga igikonjo gikonje kuruhu.Ugereranije na fibre polyester, kwinjiza amazi ni byiza, gukama vuba, ntibyoroshye amashanyarazi.Icy'ingenzi cyane, iratsinda ibitagenda neza mu mwenda wa silike nu bwoya bitoroshye kubyitaho kandi ntibyoroshye koza.Ntibyoroshye guhindura no kubyimba.
Ku bijyanye n’iterambere rirambye, imyenda ya acide triacetike ikozwe mu mbaho zifite isuku nyinshi, kandi ibikoresho fatizo byose biva mu ishyamba ry’ibidukikije rirambye riyobowe neza, rikaba ari ibikoresho birambye kandi bitangiza ibidukikije.
03.Ni gute ushobora gutandukanya aside ya diacetike na aside triacetike?
Ubucuruzi bwinshi nkimyenda ya acide triacetike nigitambara cya acide diacetique itandukanye kugirango igaragaze ibyiza bya acide triacetic.Mubyukuri, aside diacetike na acide triacetike birasa cyane.Bafite ibyiyumvo byiza kandi byoroshye kandi bitonyanga nkubudodo, kandi birwanya gukaraba no kwambara nka polyester.Nyamara, aside ya diacetike ifite fibre yoroheje cyane kandi ihinduka ryinshi ryimiterere kuruta acide triacetic, ariko irwanya kwambara kandi ihendutse.
Inzira yoroshye yo kubwira aside diacetike ivuye kuri acide triacetike ni ukureba ikirango cyibicuruzwa.Kuberako ikiguzi cyimyenda yombi kiratandukanye cyane, niba ibicuruzwa bigize acide triacetic, ikirango kizabimenya.Ntabwo byerekanwe neza ni fibre triacetate, mubisanzwe bita fibre acetate bivuga fibre diacetate.
Ukurikije ibyiyumvo, umwenda wa acide diacetike wumva wumye, adsorption nkeya;Imyenda ya Triacetate yumva yoroshye, drape ikomeye, yegereye silik.
Dufatiye ku mwuga, diacetate na triacetate byombi ni fibre acetate (izwi kandi nka fibre acetate), ikaba ari imwe mu miti ya kera y’imiti yateye imbere ku isi.Fibre ya Acetate ikozwe muri selile ya selile nkibikoresho fatizo, nyuma ya acetylation, selile ikomoka kuri selile yakozwe, hanyuma ikoresheje uburyo bwumye cyangwa butose.Cellulose irashobora kugabanywamo fibre ya diacetate na fibre triacetate ukurikije urugero rwitsinda rya hydroxyl ryasimbuwe nitsinda rya acetyl.
Vinegere ya kabiri ni ubwoko bwa acetate yo mu bwoko bwa 1 bwakozwe na hydrolysis igice, kandi urugero rwa esterification ruri munsi ya vinegere ya gatatu.Kubwibyo, imikorere yo gushyushya iri munsi ya vinegere eshatu, imikorere yo gusiga irangi kuruta vinegere eshatu, igipimo cyo kwinjiza amazi kiri hejuru ya vinegere eshatu.
Vinegere eshatu ni ubwoko bwa acetate, idafite hydrolysis, urugero rwa esterification ruri hejuru.Kubwibyo, kurwanya urumuri nubushyuhe birakomeye, imikorere yo gusiga irangi ni mibi, igipimo cyo kwinjiza amazi (nanone cyitwa igipimo cyo kugaruka).
04.Ni ikihe kiruta aside triacetike na silike ya tuteri?
Buri fibre ifite ibyiza byayo.Triacetate fibre isa na silike ya tuteri mumiterere, kumva no kunyerera.
Duhereye ku mwuga, igitekerezo cyimiterere yubukanishi, imbaraga za acetate eshatu kuruhande rwo hasi, kurambura kumeneka ni binini, igipimo cyimbaraga zitose nimbaraga zumye ni gito, ariko birenze ibya viscose rayon, intangiriro modulus ni ntoya, kugarura ubuhehere biri munsi yubudodo bwa tuteri, ariko burenze fibre ya sintetike, ikigereranyo cyimbaraga zayo zikomeye kandi zumye, imbaraga zifatika zifatika nimbaraga zipfundikizo, igipimo cyo gukira kwa elastike hamwe na silike ya tuteri.Kubwibyo, imikorere ya fibre acetate niyo yegereye silike ya tuteri muri fibre chimique.
Ugereranije na silike ya tuteri, umwenda wa acide triacetike ntabwo woroshye cyane, wakozwe mumyenda yawo ntabwo byoroshye kubyimba, urashobora gukomeza verisiyo, kubungabunga no gufata neza burimunsi.
Ubudodo bwa Mulberry, buzwi nka "fibre queen", nubwo bworoshye uruhu ruhumeka, rworoshye kandi rworoshye, rwiza kandi rwiza, ariko ibitagenda neza nabyo biragaragara cyane, kwita no kubungabunga ni ikibazo cyane, kwihuta kwamabara nabyo byoroshye munsi yimyenda isanzwe. .
Gusobanukirwa nibyiza nibibi, urashobora guhitamo imyenda yabo ukurikije ibyo bakeneye
