Maalmahan, fiilooyinka polyester-ka ayaa xisaabiya qayb weyn oo ka mid ah dharka dharka ee dadku xidhaan. Intaa waxaa dheer, waxaa jira fiilooyinka akril, fiilooyinka nylon, spandex, iwm. Fiber polyester, oo caadi ahaan loo yaqaan "polyester", oo la alifay 1941, waa noocyada ugu badan ee fiilooyinka synthetic. Faa'iidada ugu weyn ee fiber polyester-ka ayaa ah in ay leedahay iska caabin wanaagsan oo laalaabkii iyo xajinta qaabaynta, xoog badan iyo awoodda soo kabashada, waana mid adag oo adkaysi leh, laalaabka adkaysi u leh oo aan feereynin, oo aan ku dhejin dhogorta, sidoo kale waa sababta ugu weyn ee sababta. dadka casriga ah waxay jecel yihiin inay isticmaalaan.
Fiber polyester-ka waxaa lagu miiri karaa fiber staple polyester iyo fiilada polyesterka. Polyester staple fiber, oo ah polyester staple fiber, waxa loo qaybin karaa fiber staple fiber suuf ah (dherer ahaan 38mm) iyo dhogorta dhogorta ah (dhererka 56mm) si loogu daro suufka suufka iyo dhogorta. Fiilada Polyester-ka, sida fiber-ka dharka, dharkeedu wuxuu gaari karaa saameynta laalaabka iyo birta ka dib marka la dhaqo.
Faa'iidooyinka polyesterka:
1. Waxay leedahay awood sare iyo awood soo kabasho laastiig ah, sidaa darteed waa mid adag oo waara, laalaabku u adkaysta iyo birta xorta ah.
2. caabbinta iftiinka ayaa wanaagsan. Marka laga soo tago in ay ka hooseyso faybarka loo yaqaan 'acrylic fiber', caabbinta iftiinka ayaa ka fiican tan dharka dabiiciga ah ee dabiiciga ah, gaar ahaan ka dib fiber-ka dhalada, caabbinta iftiinka waxay ku dhowdahay mid la mid ah fiilada akril.
3. Dharka polyester-ka (polyester) ayaa iska caabin wanaagsan u leh kiimikooyinka kala duwan. Acid iyo alkali waxay leeyihiin waxyeelo yar. Isla mar ahaantaana, kama baqin caaryada iyo aboor.
Dhibaatooyinka polyester-ka:
1. Hygroscopicity liidata, hygroscopicity daciif ah, fududahay in la dareemo ciriiri, caabbinta dhalaalaysa liidata, fududahay in la nuugo boodhka, sababtoo ah qaabkeeda;
2. Dulqaadka hawada oo liita, ma fududa in la neefsado;
3. Waxqabadka midabaynta ayaa liidata, waxayna u baahan tahay in lagu rinjiyeeyo midabyo kala firdhiyey heerkul sare.
Dharka Polyester-ka waxaa iska leh fiber-ka aan dabiiciga ahayn, kaas oo inta badan loo isticmaalo xilliga dayrta iyo dharka jiilaalka, laakiin kuma habboona nigisyada. Polyester-ku waa u adkaysta aashitada. Isticmaal saabuunta dhexdhexaadka ah ama aashitada leh markaad nadiifinayso, saabuunta alkaline-ku waxay soo dedejin doontaa gabowga dharka. Intaa waxaa dheer, dharka polyester-ka guud ahaan uma baahna feerayn. Feeraynta uumiga heerkulka hooseeya waa OK.
Hadda qaar badan oo ka mid ah kuwa soo saara dharka ayaa inta badan isku dara ama isku dhejiya polyester-ka fiilooyinka kala duwan, sida polyester-ka suufka, polyester-ka dhogorta, iwm, kuwaas oo si weyn loogu isticmaalo qalabka kala duwan ee dharka iyo alaabta qurxinta. Intaa waxaa dheer, fiber polyester-ka waxaa loo isticmaali karaa warshadaha suunka gudbinta, teendhada, shiraac, fiilada, shabagga kalluumeysiga, iwm, gaar ahaan xadhigga polyester-ka ee loo isticmaalo taayirada, kaas oo ku dhow naylon waxqabadka. Polyester-ka waxa kale oo loo isticmaali karaa sida walaxda korantada, maro shaandhada u adkaysata aashitada, dharka warshadaha caafimaadka, iwm.
Waa kuwee fiilooyinka polyester-ka lagu qasi karo sida maaddo dhar ah, iyo dharkee ayaa badanaa la isticmaalaa?
Fiber Polyester wuxuu leeyahay awood sare, modules sare, nuugista biyaha hooseeya, waxaana si ballaaran loo isticmaalaa sida dharka madaniga ah iyo warshadaha. Maaddada dunta, polyester staple fiber waxay noqon kartaa mid saafi ah oo miiqan ama lagu qaso fiilooyinka kale, ama leh fiilooyinka dabiiciga ah sida suufka, hemp, dhogorta, ama fiilooyinka kale ee kiimikada ah sida fiber viscose, fiber acetate, fiber polyacrylonitrile, iwm.
Cudbi sida, dhogorta u eg iyo dharka sida dharka ka samaysan fiilooyinka polyester-ka ee saafiga ah ama la isku daray guud ahaan waxay leeyihiin sifooyinkii asalka ahaa ee ugu fiicnaa fiilooyinka polyesterka, sida caabbinta laalaabtay iyo iska caabinta xoqidda. Si kastaba ha ahaatee, qaar ka mid ah cilladahooda asalka ah, sida nuugista dhididka oo liita iyo qulqulka, iyo dhalaalidda fudud ee godadka marka ay la kulmaan dhimbiilo, waa la yarayn karaa oo la wanaajin karaa ilaa xad iyada oo la isku darayo fiilooyinka hydrophilic.
Polyester twisted filament (DT) ayaa inta badan loo isticmaalaa in lagu tolo xariiro kala duwan sida maryaha, waxaana sidoo kale lagu dhex-xidhi karaa fiber dabiici ah ama fiber fiber kiimikaad ah, iyo sidoo kale xariir ama fiilooyinka kale ee kiimikada. Dharkan isku xidhan ayaa ilaalinaya faa'iidooyin taxane ah oo polyesterka ah.
Noocyada ugu muhiimsan ee fiber polyester-ka ah ee laga sameeyay Shiinaha sannadihii la soo dhaafay waa polyester textured dunn (badanaa filament laastikada hooseeya DTY), taas oo ka duwan filamentiga caadiga ah waa qalafsanaan badan, qallafsanaan weyn, dhogorta dhogorta, jilicsan, oo leh dabacsanaan sare. dhererka (ilaa 400%).
Dharka ay ku jiraan polyester textured dunni waxay leedahay sifooyin diirimaad wanaagsan oo haynta, daboolka wanaagsan iyo guryaha dahaadhka, iyo dhalaalka jilicsan, sida dharka dhogorta leh, jaakad, jaakad iyo dhar qurxiyo oo kala duwan, sida daahyada, dharka miiska, dharka fadhiga, iwm.
