Ikhangeleka ngathi yisilika, kunye nokubengezela kwayo okucekethekileyo kweperile, kodwa kulula ukuyinyamekela kunesilika, yaye kulula ukuyinxiba.”Ukuva isincomo esinjalo, unokuqikelela ngokuqinisekileyo eli hlobo lelaphu lifanelekileyo - ilaphu le-triacetate.
Ngeli hlotyeni, amalaphu e-triacetate ane-silk-like luster, imvakalelo epholileyo kunye negudileyo, kunye nesondo esilengayo esigqwesileyo sizuze inkoliseko yeefashionistas ezininzi.Vula i-Little Red Book kwaye ukhangele "i-tricacetic acid", unokufumana amanqaku angaphezu kwe-10,000 ukwabelana.Ngaphezu koko, ilaphu alifuni kukhathalelwa kakhulu ukuze lihlale lithe tyaba, kwaye linokubonakala ngathi liwaka leeyuan.
Kwiminyaka yakutshanje, i-triacetate idla ngokuvela kwindlela yeenqwelo-moya kaMarc Jacobs, Alexander Wang kunye ne-Acne Studios.Yenye yezinto ekufuneka zibe nazo amalaphu entwasahlobo kunye nasehlotyeni kwiimveliso ezininzi eziphambili kwaye ibiyeyona nto kugxilwe kuyo kwiibrendi ezininzi zodidi oluphezulu.Yintoni kanye kanye i-triacetate?Ngaba ngokwenene inokuthelekiswa nesilika yokwenene?Ngaba ilaphu le-diacetic acid lingaphantsi kwe-triacetic acid?
01.Yintoni i-triacetate
I-Triacetate luhlobo lwe-Cellulose Acetate (CA), eyi-chemical fiber eyenziwe nge-Cellulose Acetate nge-chemical synthesis.Ukuyibeka ngokulula, luhlobo lwentlama yenkuni yendalo njengesixhobo ekrwada sefiber esetyenzisiweyo, luhlobo olutsha lwefiber yendalo kunye nobuchwepheshe obuphezulu obuphuhliswe yiMitsubishi Corporation yaseJapan.
02.Ziziphi iingenelo zetriacetate fiber?
I-Triacetate iyathandwa, ikakhulu ngenxa yokuba ingasetyenziswa kunye nesilika ye-mulberry, eyaziwa ngokuba "yisilika yesityalo esihlambekayo".I-Triacetate ineglosi efana ne-mulberry silk, ine-drape egudileyo, ithambile kakhulu kwaye ivelisa ukubamba okupholileyo esikhumbeni.Xa kuthelekiswa nefiber yepolyester, ukufunxwa kwayo ngamanzi kulungile, ukomisa ngokukhawuleza, akukho lula kwi-electrostatic.Okubaluleke ngakumbi, inqoba iintsilelo zesilika kunye neendwangu zoboya akulula ukuzinyamekela kwaye akukho lula ukuzihlamba.Akukho lula ukukhubaza kunye nokushwabana.
Ngokubhekiselele kuphuhliso oluzinzileyo, ilaphu le-asidi ye-triacetic lenziwe nge-pulp yomthi we-high-purity, kwaye izinto eziluhlaza zivela kwihlathi elizinzileyo le-ecological phantsi kolawulo olulungileyo, into ezinzileyo kunye ne-eco-friendly.
03.Uyahlula njani i-diacetic acid kwi-asidi ye-triacetic?
Amashishini amaninzi afana nelaphu le-triacetic acid kunye nelaphu le-diacetic acid umahluko ukuqaqambisa iingenelo ze-triacetic acid.Enyanisweni, i-diacetic acid kunye ne-triacetic acid zifana kakhulu.Banemvakalelo efanayo epholileyo kunye negudileyo kunye ne-droppiness njengesilika, kwaye bayaxhathisa ukuhlanjwa kunye nokunxiba njenge-polyester.Nangona kunjalo, i-asidi ye-diacetic inefayibha engqindilili kancinci kwaye inguqu encinci ye-texture kune-asidi ye-triacetic, kodwa iyaxhathisa kwaye iyabiza.
Eyona ndlela ilula yokuxelela i-diacetic acid kwi-triacetic acid kukujonga ileyibhile yemveliso.Ngenxa yokuba iindleko zeempahla ezimbini zihluke kakhulu, ukuba isithako semveliso yi-asidi ye-triacetic, uphawu luya kuyichonga.Ayichazwanga ngokuthe ngqo i-triacetate fiber, ebizwa ngokuba yi-acetate fiber ibhekisa kwifiber ye-diacetate.
Ukujonga kwimvakalelo, ilaphu le-asidi ye-diacetic liziva lomile, i-adsorption kancinane;Ilaphu le-Triacetate livakala ligudile ngakumbi, lilomelele, lisondele kwisilika.
Ukusuka kwimbono yobuchwephesha, zombini i-diacetate kunye ne-triacetate zeze-acetate fiber (ekwaziwa ngokuba yi-acetate fiber), eyona micu yokuqala yekhemikhali eyenziwe kwihlabathi.Ifiber ye-acetate yenziwe ngepulp ye-cellulose njengento eluhlaza, emva kwe-acetylation, i-cellulose esterified derivatives yenziwa, emva koko ngenkqubo eyomileyo okanye emanzi yokujikeleza.I-Cellulose inokwahlulwa ibe yifayibha ye-diacetate kunye ne-triacetate ifayibha ngokwenqanaba leqela le-hydroxyl endaweni yalo liqela le-acetyl.
Iviniga yesibini luhlobo lwe-acetate lwe-acetate eyenziwe yi-hydrolysis ye-partial, kwaye i-degree ye-esterification ingaphantsi kuneyesithathu iviniga.Ke ngoko, ukusebenza kokufudumeza kungaphantsi kweviniga emithathu, ukusebenza kokudaya kungcono kuneviniga emithathu, izinga lokufunxa ukufuma liphezulu kuneviniga emithathu.
Iviniga emithathu luhlobo lwe-acetate, ngaphandle kwe-hydrolysis, iqondo le-esterification liphezulu.Ke ngoko, ukukhanya kunye nokumelana nobushushu kunamandla, ukusebenza kokudaya kumbi, izinga lokufunxa ukufuma (elikwabizwa ngokuba yinqanaba lokubuyiswa komswakama) liphantsi.
04.Yeyiphi engcono kune-triacetic acid kunye nesilika ye-mulberry?
Ifiber nganye ineengenelo zayo.Ifiber ye-triacetate ifana nesilika ye-mulberry ngenkangeleko, imvakalelo kunye nokudonsa.
Ukusuka kwimbono yobuchwephesha, ithiyori yeepropathi zoomatshini, amandla ee-acetate ezintathu kwicala eliphantsi, ukophuka kobude bukhulu, umlinganiselo wamandla amanzi kunye namandla omileyo uphantsi, kodwa uphezulu kune-viscose rayon, ekuqaleni Imodulus incinci, ukufuma kwakhona kungaphantsi kunesilika ye-mulberry, kodwa iphezulu kunefayibha eyenziweyo, umlinganiselo wokuqina kwayo okumanzi kunye nokomileyo, amandla okuhambelana nekhonkco kunye nokomelela kweqhina, izinga lokubuyisela i-elastic kunye nesilika ye-mulberry.Ke ngoko, ukusebenza kwefiber ye-acetate yeyona nto ikufutshane kwi-mulberry silk kwifiber yekhemikhali.
Xa kuthelekiswa nesilika ye-mulberry, ilaphu le-asidi ye-triacetic ayilulanga kangako, eyenziwe ngeempahla zayo akukho lula ukushwabana, inokugcina inguqulelo, ukugcinwa okungcono kwemihla ngemihla kunye nokunyamekela.
Isilika ye-Mulberry, eyaziwa ngokuba "yi-fiber queen", nangona ulusu luphefumulayo, lugudileyo kwaye luthambile, luhloniphekile kwaye luhle, kodwa iintsilelo zikwabonakala kakhulu, ukukhathalela kunye nokugcinwa kuyinkathazo, ukukhawuleza kombala kukwangaphantsi kwamalaphu endalo. .
Ukuqonda ezi zibonelelo kunye nokungonakali, unokukhetha indwangu yabo ngokwezidingo zabo
