Ọ dị ka silk, nke nwere ọmarịcha pearlescent na-egbuke egbuke nke ya, ma ọ dị mfe ilekọta karịa silk, ọ na-akakwa mma iyi. N'ịnụ ndụmọdụ dị otú ahụ, ị nwere ike ịkọ n'oge okpomọkụ a kwesịrị ekwesị ákwà - akwa triacetate.
Nke a n'oge okpomọkụ, triacetate akwa na ha silk-dị ka luster, jụụ na-eji ire ụtọ mmetụta, na magburu onwe pendant mmekọahụ meriri ihu ọma nke ọtụtụ fashionistas.

Kedu ihe ọzọ, akwa ahụ anaghị achọ nlekọta dị ukwuu iji nọrọ larịị, ọ pụkwara ịdị ka otu puku yuan.
N'ime afọ ndị na-adịbeghị anya, triacetate na-apụtakarị na runway nke Marc Jacobs, Alexander Wang na Acne Studios. Ọ bụ otu n'ime akwa mmiri na ọkọchị ga-enwerịrị maka ọtụtụ ụdị isi ma bụrụkwa ihe a na-elekwasị anya nke ọtụtụ ụdị okomoko. Kedu ihe bụ triacetate kpọmkwem? Enwere ike iji ya tụnyere ezigbo silk? akwa diacetic acid ọ dị ala karịa triacetic acid?
01. Gịnị bụ triacetate
Triacetate bụ ụdị Cellulose Acetate (CA), nke bụ eriri kemịkal nke Cellulose Acetate mere site na njikọ kemịkalụ. N'ikwu ya n'ụzọ dị mfe, ọ bụ ụdị pulp osisi sitere n'okike dị ka ihe eji eme fiber emegharịrị, nke bụ ụdị eriri eke ọhụrụ na teknụzụ dị elu nke Mitsubishi Corporation nke Japan mepụtara.
02.Gịnị bụ uru nke eriri triacetate?
Triacetate na-ewu ewu, tumadi n'ihi na enwere ike iji ya na silk mulberry, nke a maara dị ka "silk osisi a na-asacha". Triacetate nwere gloss yiri nke silk mulberry, nwere akwa drape dị nro, dị nnọọ nro ma na-emepụta mmetụ dị jụụ na akpụkpọ ahụ. E jiri ya tụnyere eriri polyester, ntinye mmiri ya dị mma, ihicha ngwa ngwa, adịghị mfe electrostatic. Nke kachasị mkpa, ọ na-emeri adịghị ike nke akwa silk na ajị anụ ndị na-adịghị mfe ilekọta na ọ dịghị mfe ịsacha. Ọ dịghị mfe nrụrụ na wrink.
N'ihe gbasara mmepe na-adigide, a na-eji akwa osisi dị elu mee akwa triacetic acid, na ihe ndị a na-emepụta sitere na oke ọhịa na-adịgide adịgide n'okpuru nlekọta dị mma, nke bụ ihe na-adịgide adịgide na enyi na enyi.
03. Kedu ka esi amata ọdịiche diacetic acid na triacetic acid?
Ọtụtụ azụmaahịa dị ka akwa triacetic acid na akwa diacetic acid dị iche iji gosipụta uru nke triacetic acid. N'ezie, diacetic acid na triacetic acid yiri nnọọ. Ha na-enwe mmetụta dị jụụ na nke dị nro dị ka silk, ma na-eguzogide ọgwụ ịsacha na iyi dị ka polyester. Otú ọ dị, diacetic acid nwere eriri dị ntakịrị karịa yana mgbanwe ederede dị ntakịrị karịa triacetic acid, mana ọ na-eguzogide iyi na ọ na-efu ọnụ.
Ụzọ kachasị mfe iji gwa diacetic acid site na triacetic acid bụ ileba anya na akara ngwaahịa. N'ihi na ọnụ ahịa nke akwa abụọ ahụ dị nnọọ iche, ọ bụrụ na ngwaahịa ngwaahịa bụ triacetic acid, akara ahụ ga-achọpụta ya. A naghị akọwapụta ya kpọmkwem bụ eriri triacetate, nke a na-akpọkarị acetate fiber na-ezo aka na eriri diacetate.
Na-ekpe ikpe site na mmetụta ahụ, akwa diacetic acid na-eche na akọrọ, ntakịrị adsorption; Ngwongwo Triacetate na-enwe mmetụta nke ọma karị, na-achasi ike, na-abịaru nso silk.
Site n'echiche ndị ọkachamara, ma diacetate na triacetate bụ nke acetate fiber (nke a makwaara dị ka acetate fiber), nke bụ otu n'ime eriri kemịkal mbụ mepụtara n'ụwa. A na-eme eriri acetate nke cellulose pulp dị ka ihe eji eme ihe, mgbe acetylation gasịrị, a na-emepụta cellulose esterified derivatives, na mgbe ahụ site na akọrọ ma ọ bụ mmiri na-atụgharị usoro. Enwere ike kewaa cellulose n'ime eriri diacetate na eriri triacetate dịka ogo hydroxyl Group nke acetyl nọchiri anya ya.
Mmanya nke abụọ bụ ụdị 1 acetate nke e mepụtara site na akụkụ hydrolysis, na ogo esterification ya dị ala karịa nke mmanya nke atọ. Ya mere, arụmọrụ kpo oku na-erughị atọ mmanya, ọrụ dyeing dị mma karịa mmanya atọ, ọnụ ọgụgụ mmiri absorption dị elu karịa mmanya atọ.
Mmanya atọ bụ ụdị acetate, na-enweghị hydrolysis, ogo nke esterification dị elu. Ya mere, ọkụ na okpomọkụ na-eguzogide siri ike, ịrụ ọrụ dyeing adịghị mma, ọnụego nnabata mmiri (nke a na-akpọkwa nlọghachi mmiri) dị ala.
04. Kedu ihe dị mma karịa triacetic acid na silk mulberry?
Fiber ọ bụla nwere uru nke ya. Triacetate eriri yiri silk mulberry n'ọdịdị, mmetụta na draping.
Site na echiche ọkachamara, echiche nke ihe ndị na-emepụta ihe, ike nke acetate atọ dị n'akụkụ dị ala, na-agbaji elongation dị ukwuu, oke nke ike mmiri na ike akọrọ dị ala, ma dị elu karịa nke viscose rayon, mbụ. modul dị obere, mmiri na-enwetaghachi dị ala karịa silk mulberry, mana dị elu karịa eriri sịntetik, oke nke ike mmiri ya siri ike na akọrọ, ike nko na ike eriri, ọnụego mgbake na-agbanwe na silk mulberry. Ya mere, arụmọrụ nke eriri acetate bụ nke kacha nso na silk mulberry na eriri kemịkal.
Tụnyere mulberry silk, triacetic acid ákwà bụ otú siri, mere uwe ya adịghị mfe wrinkle, nwere ike nke ọma ịnọgide na-enwe version, mma kwa ụbọchị mmezi na-elekọta.
Mulberry silk, nke a maara dị ka "eze nwanyị fiber", ọ bụ ezie na akpụkpọ ahụ na-eku ume, dị nro ma dị nro, dị mma na nke mara mma, ma adịghị ike ya pụtakwara ìhè nke ọma, nlekọta na nlekọta na-enye nsogbu karị, ịdị ngwa agba bụkwa ihe nro dị nro nke ákwà okike. .
N'ịghọta uru na ọghọm ndị a, ị nwere ike ịhọrọ akwa nke ha dịka mkpa ha si dị
