Inoratidzika sesilika, ine pearlescent yayo pachayo yakapfava, asi iri nyore kutarisira pane sirika, uye iri nyore kupfeka.” Kunzwa kurudziro yakadaro, iwe unogona zvechokwadi kufungidzira iri zhizha rakakodzera jira - triacetate jira.
Zhizha rino, machira e-triacetate ane sirika-sekupenya kwawo, inotonhorera uye yakatsetseka kunzwa, uye yakanakisa pendant bonde yakahwina kufarirwa nevazhinji fashionistas. Vhura The Little Red Book uye tsvaga "triacetic acid", unogona kuwana zvinopfuura 10,000 manotsi ekugovera. Zvakare, jira racho haridi kutarisirwa zvakanyanya kuti rirambe rakati sandara, uye rinogona kuita sechiuru cheyuan.
Mumakore achangopfuura, triacetate yagara ichionekwa munzira yeMarc Jacobs, Alexander Wang uye Acne Studios. Ndiyo imwe yeanofanirwa-kuva nemachira echirimo uye ezhizha kune akawanda makuru mabhureki uye anga ari kutarisa kweakawanda eumbozha mhando. Chii chaizvo chinonzi triacetate? Inogona kuenzaniswa chaizvoizvo nesirika here? Iyo diacetic acid jira rakaderera kune triacetic acid?
01.Chii chinonzi triacetate
Triacetate imhando yeCellulose Acetate (CA), iri kemikari fiber yakagadzirwa neCellulose Acetate nemakemikari synthesis. Kuzvitaura zviri nyore, imhando yehuni yechisikigo pulp seyakabikwa yefiber yakadzokororwa, inova rudzi rutsva rwechisikigo uye yakakwira-tech fiber yakagadzirwa neMitsubishi Corporation yekuJapan.
02.Ndezvipi zvakanakira triacetate fiber?
Triacetate inonyanya kufarirwa, kunyanya nekuti inogona kushandiswa nesirika yemurubheri, inozivikanwa se "washable plant silk". Triacetate ine gloss yakafanana neyemurubheri sirika, ine dhiraivha yakatsetseka, yakanyanya kupfava uye inoburitsa inotonhorera kubata paganda. Kuenzaniswa nefiber yepolyester, kunyura kwayo mvura kwakanaka, kuomesa nekukurumidza, kwete nyore kumagetsi. Zvinonyanya kukosha, inokunda kukanganisa kwesilika uye machira emvere izvo zvisiri nyore kutarisira uye kwete nyore kushambidza. Hazvisi nyore kukanganisa uye kuunyana.
Panyaya yekusimudzira kwakasimba, triacetic asidhi jira rakagadzirwa nepamusoro-kuchena huni pulp, uye zvigadzirwa zvese zvinobva kusango rakagadzikana rezvipenyu riri pasi pekutonga kwakanaka, chinova chinhu chakasimba uye chinoshamwaridzana.
03.Kusiyanisa sei diacetic acid kubva kune triacetic acid?
Mabhizinesi mazhinji senge triacetic asidhi jira uye diacetic asidhi jira mutsauko kuratidza zvakanakira triacetic acid. Muchokwadi, diacetic asidhi uye triacetic asidhi zvakafanana. Vane zvakafanana inotonhorera uye yakatsetseka kunzwa uye kudonha sesirika, uye inoshingirira kugeza nekupfeka sepolyester. Nekudaro, diacetic asidhi ine faibha yakati kukora uye kushomeka kwemavara anochinja pane triacetic asidhi, asi yakanyanya kusakara uye inodhura.
Nzira iri nyore yekuudza diacetic acid kubva ku triacetic acid ndeyekutarisa chigadzirwa label. Nekuti mutengo wemachira maviri akasiyana, kana chigadzirwa chemukati chiri triacetic acid, mhando inozoizivisa. Hazvina kutaurwa zvakananga ndeye triacetate fiber, inowanzonzi acetate fiber inoreva diacetate fiber.
Tichitarisa kubva pakunzwa, diacetic acid jira rinonzwa rakaoma, zvishoma adsorption; Triacetate jira rinonzwa zvakanyanya kutsvedzerera, drape rakasimba, pedyo nesirika.
Kubva kunyanzvi yekuona, zvose diacetate uye triacetate ndezveacetate fiber (inozivikanwawo seacetate fiber), inova imwe yemakemikari ekutanga akagadzirwa munyika. Acetate fiber inogadzirwa ne cellulose pulp seyakabikwa, mushure meacetylation, cellulose esterified derivatives inogadzirwa, uyezve nekuoma kana kunyorova kutenderera maitiro. Cellulose inogona kukamurwa kuita diacetate fiber uye triacetate faibha zvichienderana nechiyero cheboka rehydroxyl rakatsiviwa neboka reacetyl.
Yechipiri vhiniga imhando 1 acetate yakaumbwa nechidimbu hydrolysis, uye esterification dhigirii rayo rakaderera pane rechitatu vhiniga. Naizvozvo, kuita kwekudziya kusingasviki matatu vhiniga, kuita kwedhayi kuri nani pane matatu vhiniga, mwero wekunyudza hunyoro wakakwira kupfuura matatu vhiniga.
Vatatu vhiniga imhando yeacetate, isina hydrolysis, dhigirii re esterification rakakwirira. Naizvozvo, mwenje uye kupisa kuramba kwakasimba, kuita kwedhayi kwakashata, mwero wekunyudza hunyoro (unonziwo hunyoro hwekudzoka) hwakaderera.
04.Ndezvipi zviri nani pane triacetic acid uye sirika yemubheri?
Imwe neimwe fiber ine zvayakanakira. Triacetate fiber yakafanana nesirika yemurubheri pakuonekwa, kunzwa uye kudonhedza.
Kubva pakuona kwehunyanzvi, dzidziso yemechanical properties, simba reacetate matatu padivi rakadzika, kutyora kureba kwakakura, chiyero chesimba rakanyorova uye kuoma kwesimba rakaderera, asi rakakwirira kupfuura reviscose rayon, yekutanga. modulus idiki, kunyorova kudzoreredza kwakadzikira pane sirika yemurubheri, asi yakakwirira kupfuura synthetic fiber, chiyero chesimba rayo rakasimba rakanyorova uye rakaoma, simba rehuku uye simba repfundo, iyo elastic kupora mwero uye mulberry silk. Naizvozvo, kuita kweacetate fiber ndiyo iri padyo nesiriki yemurubheri mumakemikari fiber.
Kuenzaniswa nesirika yemuberry, jira re triacetic acid harina kutetepa, rakagadzirwa nembatya dzaro hazvisi nyore kuunyana, rinogona kuchengetedza shanduro, kuchengetedza zviri nani zuva nezuva uye kutarisira.
Mulberry silk, inozivikanwa se "fiber queen", kunyange zvazvo ganda rinofema, rakapfava uye rakapfava, rakanaka uye rinoyevedza, asi zvikanganiso zviri pachena zvakare, kutarisira uye kugadzirisa kunonyanya kunetsa, kukurumidza kwemavara ndiko zvakare kunyorova kwezasi kwemachira echisikigo. .
Kunzwisisa izvi zvinobatsira uye zvisingabatsiri, unogona kusarudza jira ravo maererano nezvavanoda
