Dacron waa noocyo kala duwan oo muhiim ah oo fiber synthetic ah waana magaca ganacsiga ee fiber polyester ee Shiinaha.Waxay ku salaysan tahay terephthalic acid la safeeyey (PTA) ama dimethyl terephthalic acid (DMT) iyo ethylene glycol (MEG) sida alaabta ceeriin, iyada oo loo marayo esterification ama transesterification iyo falcelinta polycondensation iyo diyaarinta polymer - polyetylen terephthalate (PET), wareeg iyo post- farsamaynta ka samaysan fiber.Waxa loogu yeero xuubka polyester-ka waa dhererka in ka badan kiiloomitir oo xariir ah, fiilku wuxuu ku dhaawacmay kubbadda.Sida laga soo xigtay hababka wax soo saarka ee kala duwan, polyester-ka guud ahaan waxaa loo qaybiyaa saddex qaybood: filaha aasaasiga ah, filaha fidsan iyo fiilada qallafsan.
Astaamaha fiilaha polyesterka
Xoog: Fiilooyinka polyesterku waxay ku dhow yihiin laba jeer inay ka xoog badan yihiin suufka iyo saddex jeer waxay ka xoog badan yihiin dhogorta, sidaas darteed dharka polyesterka waa kuwo xoog badan oo waaraya.
Iska caabinta kulaylka: waxaa loo isticmaali karaa -70 ℃ ~ 170 ℃, waa iska caabbinta kulaylka ugu fiican iyo xasiloonida kulaylka ee fiilooyinka synthetic.
Elasticity: Laastikada polyester-ka waxay ku dhowdahay dhogorta, caabbinta cirifka ayaa ka fiican fiilooyinka kale.Dharka ayaa ah mid aan laalaabmin oo waxay leedahay haynta qaab wanaagsan.
Xiro iska caabin: Polyester-ka caabbinta iska caabbinta ayaa ah ka labaad oo kaliya naylon, booska labaad ee fiber synthetic.
Nuugista biyaha: Polyester waxay leedahay nuugista biyaha hooseeya iyo heerka soo kabashada qoyaanka iyo waxqabadka dahaarka wanaagsan.Si kastaba ha ahaatee, sababtoo ah nuugista biyaha oo hooseeya iyo koronto taagan oo sarreeya oo ay dhaliso isqabqabsigu, waxqabadka dabiiciga ah ee dheehu waa mid liita.Sidaa darteed, polyester-ka guud ahaan waxaa lagu rinjiyeeyaa heerkulka sare iyo midabaynta cadaadiska sare.
Dheejinta: Polyester-ka lafteedu waxa ay ka maqan tahay kooxo hydrophilic ah ama qaybo aqbala dheeha, markaa dheehidda polyesterku waa mid liidata, waxaa lagu rinjiyeeyaa midabyo kala firdhisan ama midabyo aan ionic ahayn, laakiin xaaladaha midabaynta ayaa adag.
Isticmaalka fiilada polyester-ka
Polyester sida fiber-ka dharka, dharkeeda ka dib marka la dhaqo si loo gaaro saameynta aan laalaabin, aan-feereynin.Polyester-ka waxaa inta badan lagu daraa ama lagu dhex-xidhaa fiilooyinka kala duwan, sida polyester-ka suufka ah, polyester-ka dhogorta, iwm, oo si ballaaran loo isticmaalo noocyada kala duwan ee alaabta dharka iyo alaabta qurxinta.Polyester-ka waxaa loo isticmaali karaa warshadaha suunka gudbinta, teendhada, shiraac, fiilada, shabagga kalluumeysiga, iwm, gaar ahaan xadhigga polyester-ka ee taayirka, kaas oo ku dhow naylon waxqabadka.Polyester sidoo kale waxaa loo isticmaali karaa in qalabka dahaarka korantada, maro filter acid-u adkaysta, dharka warshadaha dawooyinka, iwm fiber synthetic ayaa si ballaaran loo isticmaalo beeraha kala duwan ee dhaqaalaha qaranka sababtoo ah xoog sare, caabin abrasion, caabbinta acid, caabbinta alkali, sare. caabbinta heerkulka, miisaanka fudud, diirimaadka, dahaarka koronto oo wanaagsan iyo caariyaysi caariyaysi.
