E shebahala joaloka silika, e nang le khanya ea eona e nyenyane ea perela, empa ho bonolo ho e hlokomela ho feta silika, ’me ho bonolo ho e apara.”Ha u utloa tlhahiso e joalo, ka sebele u ka hakanya lehlabuleng lena lesela le loketseng - lesela la triacetate.
Lehlabuleng lena, masela a triacetate a nang le khanya e kang silika, maikutlo a pholileng le a boreleli, le thobalano e ntle ea pendant e hapile mohau oa li-fashionistas tse ngata.Bula Buka e Nyenyane e khubelu 'me u batle "triacetic acid", u ka fumana lintlha tse fetang 10,000 tseo u ka li arolelanang.Ho feta moo, lesela ha le hloke tlhokomelo e ngata hore le lule le bataletse, 'me le ka shebahala joaloka li-yuan tse sekete.
Lilemong tsa morao tjena, hangata triacetate e hlahile tseleng ea lifofane ea Marc Jacobs, Alexander Wang le Acne Studios.Ke e 'ngoe ea masela a lokelang ho ba le nako ea selemo le ea lehlabula bakeng sa lihlahisoa tse ngata tse kholo' me e 'nile ea e-ba sepheo sa mefuta e mengata ea mabothobotho.Hantle-ntle triacetate ke eng?Na e hlile e ka bapisoa le silika ea sebele?Na lesela la diacetic acid le tlase ho triacetic acid?
01.Triacetate ke eng
Triacetate ke mofuta oa Cellulose Acetate (CA), e leng fiber ea lik'hemik'hale e entsoeng ka Cellulose Acetate ka motsoako oa lik'hemik'hale.Ka mantsoe a bonolo, ke mofuta oa makhasi a tlhaho a lehong e le thepa e tala ea fiber e tsosolositsoeng, e leng mofuta o mocha oa fiber ea tlhaho le ea theknoloji e phahameng e entsoeng ke Mitsubishi Corporation ea Japane.
02.Melemo ea triacetate fiber ke efe?
Triacetate e tumme, haholo hobane e ka sebelisoa le silika ea amora, e tsejoang e le "silika ea semela se hlatsuoang".Triacetate e na le gloss e ts'oanang le silika ea mulberry, e na le drape e boreleli, e bonolo haholo 'me e hlahisa letlalo le phodileng.Ha ho bapisoa le fiber ea polyester, ho monya ha eona ha metsi ho molemo, ho omella ka potlako, ha ho bonolo ho electrostatic.Habohlokoa le ho feta, e hlōla mefokolo ea masela a silika le a boea ao ho seng bonolo ho a hlokomela ebile ho seng bonolo ho a hlatsoa.Ha ho bonolo ho holofala le ho sosobana.
Mabapi le nts'etsopele e tsitsitseng, lesela la triacetic acid le entsoe ka makhasi a lehong a hloekileng, 'me lisebelisoa tsohle li tsoa morung o tsitsitseng oa tikoloho tlas'a tsamaiso e ntle, e leng ntho e tsitsitseng le eco-friendly.
03.Ho khetholla diacetic acid ho triacetic acid?
Likhoebo tse ngata tse kang lesela la triacetic acid le lesela la diacetic li fapane ho totobatsa melemo ea triacetic acid.Ha e le hantle, diacetic acid le triacetic acid li tšoana haholo.Li na le maikutlo a tšoanang a pholileng le a boreleli le marotholi joaloka silika, 'me ha li khone ho hlatsoa le ho roala joaloka polyester.Leha ho le joalo, diacetic acid e na le fiber e teteaneng hanyenyane 'me sebopeho sa sebopeho se fokola ho feta triacetic acid, empa ha e senyehe ebile e boloka chelete e ngata.
Mokhoa o bonolo oa ho tseba asiti ea diacetic ho triacetic acid ke ho sheba leibole ea sehlahisoa.Hobane litšenyehelo tsa masela a mabeli a fapane haholo, haeba sehlahisoa sa sehlahisoa ke triacetic acid, letšoao le tla le khetholla.Ha ho boletsoe ka ho hlaka hore fiber ea triacetate, eo hangata e bitsoang fiber ea acetate e bolela fiber ea diacetate.
Ho latela maikutlo, lesela la diacetic acid le ikutloa le omme, le khahleha hanyane;Lesela la triacetate le ikutloa le boreleli haholoanyane, le le matla, le le haufi le silika.
Ho ea ka pono ea setsebi, bobeli ba diacetate le triacetate ke ba fiber ea acetate (eo hape e tsejoang e le fiber ea acetate), e leng e 'ngoe ea likhoele tsa pele tsa lik'hemik'hale tse entsoeng lefatšeng.Fiber ea acetate e entsoe ka makhasi a selulose e le lisebelisoa tse tala, ka mor'a hore acetylation e thehoe, ho thehoa li-derivatives tse entsoeng ka selulose, ebe ka mokhoa o omileng kapa o metsi.Cellulose e ka aroloa ka fiber ea diacetate le fiber ea triacetate ho latela tekanyo ea sehlopha sa hydroxyl se nkeloang sebaka ke sehlopha sa acetyl.
Asene ea bobeli ke mofuta oa acetate oa mofuta oa 1 o entsoeng ka karolo ea hydrolysis, 'me tekanyo ea eona ea esterification e tlase ho feta ea asene ea boraro.Ka hona, ts'ebetso ea ho futhumatsa e ka tlase ho asene e meraro, ts'ebetso ea ho daea e betere ho feta asene e meraro, sekhahla sa ho monya mongobo se phahame ho feta asene e meraro.
Asene e meraro ke mofuta oa acetate, ntle le hydrolysis, tekanyo ea esterification e phahame.Ka hona, ho hanyetsa khanya le mocheso ho matla, ts'ebetso ea ho daea e fokola, sekhahla sa ho monya mongobo (hape se bitsoa sekhahla sa ho khutla ha mongobo) se tlase.
04.Ke efe e molemo ho feta triacetic acid le silika ea amora?
Fiber ka 'ngoe e na le melemo ea eona.Fiber ea triacetate e ts'oana le silika ea amora ka chebahalo, maikutlo le ho hula.
Ho ea ka pono ea setsebi, khopolo ea thepa ea mechine, matla a li-acetate tse tharo ka lehlakoreng le tlaase, bolelele bo robehileng bo boholo, karo-karolelano ea matla a metsi le matla a omileng a tlaase, empa a phahame ho feta a viscose rayon, qalong. modulus e nyane, ho khutlisa mongobo ho tlase ho feta silika ea amora, empa e phahame ho feta fiber ea maiketsetso, karo-karolelano ea matla a eona a matla a metsi le a omileng, matla a hook a amanang le matla a lefito, sekhahla sa ho hlaphoheloa le silika ea amora.Ka hona, ts'ebetso ea fiber ea acetate ke eona e haufi haholo le silika ea mulberry ka fiber ea lik'hemik'hale.
Ha ho bapisoa le silika ea amora, lesela la triacetic acid ha le bonolo hakaalo, le entsoeng ka liaparo tsa lona ha le bonolo ho sosobana, le ka boloka phetolelo, le tlhokomelo e ntle ea letsatsi le letsatsi le tlhokomelo.
Silika ea mulberry, e tsejoang e le "fiber queen", le hoja letlalo le phefumoloha, le boreleli ebile le bonolo, le hlompheha ebile le khabane, empa mefokolo e boetse e totobetse haholo, tlhokomelo le tlhokomelo li thata le ho feta, ho potlaka ha mebala ho boetse ho le bonolo ka tlas'a masela a tlhaho. .
Ho utloisisa melemo le melemo ena, o ka khetha lesela la bona ho latela litlhoko tsa bona
