Kwiminyaka emibini edlulileyo, abayili badla ngokuthi "ilaphu le-acetic acid" kunye "nelaphu le-triacetic acid", baze emva koko bajikeleze isandi nge-3D, "andinakukwazi!" "Hayi ukufa! Andinakuyisebenzisa!" Olu hlobo lwelaphu lukwathandwa kakhulu ziinkampani zophawu oluphezulu kwiminyaka emibini edlulileyo, ke liphi?
Yabelana ngazo zonke iintlobo zezinto ezomileyo ze-acetic acid ngoko nangoko, uphi, kwaye kwinkqubo yokwenza uyilo lwempahla, senza amalaphu e-acetic acid abize kakhulu? Yisebenzise kakuhle.
1. I-asidi ye-aceticilaphu
I-acetate fiber luhlobo lwefayibha yokwenziwa, yinto yefayibha eyenziwe ngokwe-semi-synthetic, yi-cellulose kunye ne-acetic anhydride reaction ukuze kufunyanwe i-fiber acetate, ize emva koko kwenziwe i-cellulose acetate fiber. I-ACETATE fiber, eyaziwa ngokuba yilaphu le-acetate, oko kukuthi, abantu badla ngokuthi ilaphu le-acetic acid, elaziwa ngokuba yilaphu le-acetate, elaziwa ngokuba yiYasha, ligama lesiTshayina elithi acetate yesiNgesi.
I-acetate fiber inokwahlulwa ibe ziintlobo ezimbini ze-acetate fiber kunye ne-acetate fiber ezintathu. Yintoni umahluko phakathi kweeviniga ezimbini nezithathu?
(1) Iviniga ezintathu luhlobo lwe-acetate, ngaphandle kwe-hydrolysis, kwaye inqanaba layo le-esterification liphezulu. Ngenxa yoko, ukumelana nokukhanya nobushushu kunamandla, ukusebenza kokudaya kuphantsi, kwaye izinga lokufunxwa komswakama (okwaziwa ngokuba yi-moisture recover rate) liphantsi.
(2) Iviniga ezimbini luhlobo lwe-acetate eyenziwe emva kwe-hydrolysis engaphelelanga, kwaye inqanaba layo le-esterification liphantsi kuneleviniga ezintathu. Ke ngoko, ukusebenza kobushushu akukuhle njengeviniga ezintathu, ukusebenza kokudaya kungcono kuneviniga ezintathu, kwaye izinga lokufunxwa komswakama liphezulu kuneviniga ezintathu.
2. Ilaphu le-asidi yeTriacetic
I-Triacetate isetyenziswa rhoqo kuyilo lwethu lwefashoni. Namhlanje, sigxila kwilaphu le-triacetate elilelaphu le-acetic acid ecolekileyo, ngoko ke i-triacetate ukongeza kwixabiso eliphakamileyo, elibizayo, nelibiza kakhulu ~ wonke umzimba unezibonelelo ~
I-Triacetate, phantsi kwegama elithi SOALON, isuka kwi-conifers ezikhuliswe eKhanada naseAlaska. Yifayibha ecocekileyo engaphantsi kokwenziwa, eyenziwe yiMitsubishi Rayon Company yaseJapan, uhlobo olutsha lwendibaniselwano yendalo neyetekhnoloji ephezulu yelaphu, enobuthambile obufanayo neefayibha zendalo, kodwa isiphumo sayo siyafana neefayibha zokwenziwa.
Kwinkqubo yokwenziwa kwe-acetate fiber, iqondo le-esterification lingaphezulu kwe-2.7, libizwa ngokuba yi-triacetate fiber, kwaye ilaphu elenziwe nge-triacetate fiber libizwa ngokuba yi-triacetate fabric.
3. I-PK enemicu yendalo kunye nemicu eyenziwe ngumntu
Inkangeleko kunye nokukhazimla kwefayibha ye-triacetate kufana noko kwesilika ye-mulberry. Imvakalelo yokuthamba kunye nokugudama ifana noko kwesilika ye-mulberry, kwaye ubunzima bayo obuthile bufana nobesilika ye-mulberry, ngoko ke akukho nto ingaqhelekanga kwisilika yomile kunye ne-mulberry. Uphawu kukuba ixabiso leefayibha zendalo liye landa kwiminyaka yakutshanje, kwaye i-triacetic acid iye yaba yindawo elungileyo.
Ngoko ke, akukho bumdaka obungaqhelekanga kunye nesilika. Uphawu kukuba ixabiso leefayibha zendalo liye lanyuka kwiminyaka yakutshanje, kwaye i-triacetic acid iye yaba yindawo efanelekileyo yokuthatha indawo.
Amanqaku okuphumelela:
(1) Ilaphu lesilika elineentsholongwane, uthuli kwaye linokucoca kuphela, kodwa akukho lula ukuvelisa umbane ongashukumiyo, akukho lula ukufunxa uthuli emoyeni, kwaye akukho laphu lesilika kulula ukulitya, kulula ukulinyamekela.
(2) Ine-thermoplasticity elungileyo, imilo yayo kulula ukuyilungisa, xa ithelekiswa nezinto ze-hemp, ayibimbi lula, ine-mobility yokufunxa umswakama yelinen, kwangaxeshanye, inemvakalelo yokuba ndindisholo, ivakalelwa kukubanda xa inxitywa.
(3) Ngenxa yentuthuzelo yeefayibha zendalo, oku kungcono kuneefayibha zokwenziwa. Kwangaxeshanye, ukuthamba kweefayibha ze-viscose kungcono, kodwa kulula nokudaya, kwaye umbala ukhawuleza kakhulu.
4. Ukusetyenziswa kunye nokubekwa kwelaphu le-acetic acid kuyilo lwempahla
Ixabiso lelaphu le-acetic acid libiza kakhulu, kugqitywa ukuba kusetyenziswe impahla ekumgangatho ophezulu, kunye nezinye izinto ze-satin, okanye izinto ze-TR azinakutshintshwa, ngokwebhanti yexabiso lophawu, ukuze kubonwe ukuba zifanelekile na kuphawu.
(1) Uyilo lwefashoni --ilokhwe
Ilaphu le-acetic acid lokwenzailokhwe yokutyibiliza, yindlela ye-ace, kwaye singaba neendlela ezininzi ezahlukeneyo zokutolika ngokwee-sag ezahlukeneyo zelaphu, kunye nesitayile sobume belaphu.
Uhlobo: uSsheena
Izithako: i-triacetate 82%, i-ethylene 18%)
(2) Uyilo lwefashoni -- iibhulukhwe
Okanye isaci sakudala: uyilo lwesitayile sebhulukhwe, alunakwahlulwa ububanzi kunye nokugoba kwelaphu. Izinto ze-acetic acid ziyafana, nikela ingqalelo kwimvakalelo ye-satin ye-acetic acid, kwaye ziya kubamba isenzeko.
Uhlobo: 3.1 Phillip Lim
Izithako: I-Triacetate 66%, i-polyester 34%)
(3) Uyilo lwefashoni -- Iingubo
Uhlobo: uCalvin Klein
Izithako: I-Triacetate 81%, iPolyester 19%)
(4) Uyilo lweempahla -- iihempe
Uhlobo: T Ngu-Alexander Wang
Izithako: I-Triacetate 86%, i-polyester 14%)
