Waxay u egtahay xariir, oo leh dhaldhalaal jilicsan oo u gaar ah, laakiin way ka sahlan tahay in la daryeelo xariirta, wayna raaxo badan tahay in la xidho."Markaad maqasho taladan oo kale, waxaad hubaal ka dhigan kartaa xagaagan dharka ku habboon - dharka triacetate.
Xagaagan, dharka triacetate oo leh xarrago xariir ah oo u eg, dareen qabow oo siman, iyo galmo qallafsan oo aad u fiican ayaa ku guuleystay fashionistas badan.Fur buug-yaraha cas oo raadi "triacetic acid", waxaad ka heli kartaa in ka badan 10,000 oo qoraal ah oo aad wadaagto.Waxa intaa dheer, dharku uma baahna daryeel badan si uu u sii joogo, oo wuxuu u ekaan karaa kun yuan.
Sanadihii la soo dhaafay, triacetate ayaa inta badan ka soo muuqday wadada Runway ee Marc Jacobs, Alexander Wang iyo Acne Studios.Waa mid ka mid ah dharka gu'ga iyo xagaaga ee loogu talagalay noocyo badan oo waaweyn waxayna ahayd diiradda noocyo badan oo raaxo ah.Waa maxay dhab ahaantii triacetate?Runtii ma la barbar dhigi karaa xariir dhab ah?Dharka diacetic acid miyuu ka hooseeyaa triacetic acid?
01.Waa maxay triacetate
Triacetate waa nooc ka mid ah Cellulose Acetate (CA), kaas oo ah fiber kiimiko ah oo laga sameeyay Cellulose Acetate by synthesis kiimikaad.Si fudud loo dhigo, waa nooc ka mid ah saxarka alwaaxda dabiiciga ah sida alaabta ceeriin ee fiber-ka dib loo warshadeeyay, taas oo ah nooc cusub oo fibre dabiici ah oo heersare ah oo ay samaysay Shirkadda Mitsubishi ee Japan.
02.Waa maxay faa'iidooyinka fiber triacetate?
Triacetate waa caan, inta badan sababtoo ah waxaa loo isticmaali karaa xariirta bulk, oo loo yaqaan "xariir dhirta la dhaqi karo".Triacetate waxay leedahay dhalaal la mid ah xariirta mulberry, waxay leedahay daahyo siman, aad bay u jilicsan tahay waxayna soo saartaa taabasho qabow oo maqaarka ah.Marka la barbardhigo fiber polyester-ka, nuugista biyuhu waa wanaagsan tahay, si degdeg ah u engejin, ma fududa in elektrostatic.Tan ka sii muhiimsan, waxay ka gudubtaa cilladaha dharka xariirta iyo dhogorta ee aan sahlanayn in la daryeelo oo aan sahlanayn in la dhaqo.Ma fududa in la qalloobo oo laalaabto.
Marka la eego horumarinta joogtada ah, dharka triacetic acid wuxuu ka samaysan yahay saxarka alwaax-sadiif ah oo sarreeya, iyo alaabta ceeriin waxay dhammaantood ka soo jeedaan kaynta deegaanka ee joogtada ah ee maaraynta wanaagsan, taas oo ah walxo waara iyo deegaan-saaxiibtinimo.
03. Sidee loo kala soocaa diacetic acid iyo triacetic acid?
Ganacsiyo badan ayaa jecel dharka triacetic acid iyo dharka diacetic acid ka duwan si ay u muujiyaan faa'iidooyinka triacetic acid.Dhab ahaantii, diacetic acid iyo triacetic acid aad bay isugu dhow yihiin.Waxay leeyihiin dareen qabow oo siman iyo hoos u dhac la mid ah sida xariirta, wayna u adkaysanayaan dhaqidda iyo xidhashada sida polyesterka oo kale.Si kastaba ha ahaatee, aashitada diacetic waxay leedahay fiber wax yar ka dhumuc weyn iyo isbeddelo muuqaal ah oo ka yar triacetic acid, laakiin way adkaysi badan tahay oo kharash-ool bay u tahay.
Sida ugu fudud ee diacetic acid looga sheegi karo triacetic acid waa in la eego calaamadda alaabta.Sababtoo ah qiimaha labada dhar ayaa aad u kala duwan, haddii maaddada alaabadu ay tahay triacetic acid, calaamad ayaa aqoonsan doonta.Si gaar ah looma tilmaamin waa fiber triacetate, guud ahaan loo yaqaan fiber acetate waxaa loola jeedaa fiber diacetate.
Marka la eego dareenka, dharka diacetic acid waxay dareemaan qallayl, wax yar oo la dareemo;Dharka 'Triacetate' ayaa dareemaya siman, daahyo xoog leh, oo u dhow xariir.
Marka laga eego aragtida xirfadeed, labadaba diacetate iyo triacetate waxay ka tirsan yihiin fiber acetate (sidoo kale loo yaqaan fiber acetate), taas oo ah mid ka mid ah fiilooyinka kiimikada ugu horreeya ee lagu sameeyay adduunka.Fiber Acetate wuxuu ka samaysan yahay saxarka cellulose sida alaabta ceeriin, ka dib acetylation, cellulose esterified derivatives ayaa la sameeyay, ka dibna habka qallafsan ama qoyan.Cellulose waxaa loo qaybin karaa fiber diacetate iyo fiber triacetate iyadoo loo eegayo heerka kooxda hydroxyl ee lagu beddelay kooxda acetyl.
Khalka labaad waa nooca 1 acetate oo ay samaysay qayb ka mid ah hydrolysis, iyo shahaadada esterification waxay ka hooseysaa kan khalka saddexaad.Sidaa darteed, waxqabadka kuleylku wuxuu ka yar yahay saddex khal, waxqabadka midabaynta ayaa ka fiican saddex khal, heerka nuugista qoyaanku wuxuu ka sarreeyaa saddex khal.
Saddex khal waa nooc ka mid ah acetate, iyada oo aan lahayn hydrolysis, heerka esterification waa sare.Sidaa darteed, caabbinta iftiinka iyo kulaylku waa mid xooggan, waxqabadka dheeha ayaa liidata, heerka nuugista qoyaanka (sidoo kale loo yaqaan heerka soo celinta qoyaanka) ayaa hooseeya.
04. Keebaa ka wanaagsan triacetic acid iyo xariirta bulk?
Fiber kasta wuxuu leeyahay faa'iidooyin u gaar ah.Fiber Triacetate waxay la mid tahay xariirta bulberry muuqaal ahaan, dareemo iyo duubid.
Marka laga eego aragtida xirfadeed, aragtida guryaha farsamada, xoogga saddexda acetate ee dhinaca hoose, dhererka jebinta waa ka weyn yahay, saamiga xoogga qoyan iyo xoogga qallalan waa hooseeyaa, laakiin ka sarreeya tan viscose rayn, bilawga modules waa yar yahay, soo celinta qoyaanku wuu ka hooseeyaa xariirta bubka, laakiin wuxuu ka sarreeyaa fiber synthetic, saamiga xooggiisa qoyan iyo xoogga qallalan, xoogga jillaab qaraabo ah iyo xoogga guntinka, heerka soo kabashada laastikada iyo xariirta bulk.Sidaa darteed, waxqabadka fiber acetate waa kan ugu dhow xariirta bulberry ee fiber kiimikaad.
Marka la barbardhigo xariirta bulk, dharka triacetic acid ma aha mid aad u jilicsan, oo ka samaysan dharkeeda ma fududa in la duuduubo, waxay si fiican u ilaalin kartaa nooca, dayactirka maalinlaha ah iyo daryeelka maalinlaha ah.
Xariirka Mulberry, oo loo yaqaan "boqoradda fiber", inkasta oo maqaarka saaxiibtinimo uu neefsanayo, siman oo jilicsan, sharaf leh oo qurux badan, laakiin cilladuhu sidoo kale waa mid aad u muuqda, daryeelka iyo dayactirka ayaa aad u dhib badan, midabka midabka sidoo kale waa jilicsanaanta jilicsan ee dharka dabiiciga ah. .
Fahamka faa'iidooyinkan iyo khasaarooyinkaas, waxaad dooran kartaa dharkooda iyaga oo raacaya baahidooda
