Fiber polyester, oo badanaa loo yaqaan "polyster".Waa fiber-synthetic ah oo laga helay polyester-wareega oo laga helay polycondensation of dibasic acid organic iyo aalkolada dihydric.Waa iskudhis polymer waana noocyada ugu badan ee fiilooyinka synthetic ee hadda jira.Dharka polyester-ka ayaa si weyn loogu isticmaalaa warshadaha habeynta shandadaha, iyo dharka polyester-ka waxaa loo isticmaalaa badeecooyin badan oo bac ah.Sidaa darteed, haddii aad aragto "fiber polyester" oo ku qoran sharaxaadda alaabta ee sumadda dhabarka mustaqbalka, ka dibna boorsada dhabarku waxay ka samaysan tahay dhar polyester ah.
Dharka polyesterka waa mid ka mid ah dharka caadiga ah ee boorsooyinka dhabarka.Waxay leedahay iska caabin laalaab oo aad u fiican, xajinta qaabka, awood sare iyo awoodda soo kabashada laastikada, caabbinta laalaabka, laalaab la'aan, timo aan dhejin iyo faa'iidooyin kale.
1. Barafnimada dharka polyester-ka ayaa wanaagsan
Dharka Polyester-ka ayaa leh awood sare iyo awood dib u soo kabasho, waxayna leedahay caabin wanaagsan oo laalaabkii iyo xajinta qaabka.Waxaa loo isticmaalaa in lagu sameeyo boorsooyinka dhabarka.Boorsada dhabarka ee dhammaatay waa mid xoog badan oo adkaysi u leh.Dharka si sahal ah uma qalloocin hoos ficilka xoogga dibadda, aad u laalaab u adkaysta, asal ahaanna uma baahna feerayn., qaabka baakadku wuxuu ahaan doonaa mid siman, saddex-cabbir ah iyo qaabaysan.Isticmaalka caadiga ah, boorsooyinka dhabarka ee ka samaysan dharka polyesterka ayaa ah kuwo aad u raaga oo aan si fudud u qalloocin.
2. Iska caabin iftiin wanaagsan
Iftiinku waa kan labaad oo kaliya akril (dhogor macmal ah).Xakamaynta iftiinka ee dharka polyester-ka ayaa ka fiican kan fiilada akril, iftiinkeeduna wuu ka fiican yahay midka dabiiciga ah ee dabiiciga ah.Gaar ahaan iftiinka iftiinka ee ka dambeeya muraayadda ayaa ah mid aad u wanaagsan, oo ku dhow la siman akril.Badeecadaha boorsada dhabarka ee laga sameeyay dharka polyester-ka uma nugul cimilada, dillaaca iyo jabka marka lagu isticmaalo xaaladaha dibadda.

3. Midabaynta liidata
Inkasta oo dharka polyester-ka uu leeyahay midab khafiif ah, waxay leedahay midab wanaagsan.Marka si guul leh loo midabeeyo, si sahal ah uma libdhi doonto, si sahal ahna uma lumi doonto inta lagu jiro habka dhaqidda.Waxaa lagu sameeyaa badeecada dhabarka, dharkuna ma fududa in la tirtiro ka dib isticmaalka muddada dheer, iyo saameynta sii-haynta midabku waa mid aad u wanaagsan.
;
4. Hygroscopicity liidata
Hygroscopicity ee polyester-ka way ka daciifsan tahay tan naylon, sidaa darteed dabaysha hawadu uma fiicna sida naylon, laakiin waa si sax ah sababtoo ah hygroscopicity liidata ee dharka polyesterka in dharka polyesterku ay fududahay in la qalajiyo ka dib marka la dhaqo, iyo xoogga dharka si dhib leh ayuu u yaraadaa, markaa ma fududa in la qaabeeyo.Badeecadaha boorsada dhabarka ee la soo saaray waxay isticmaalaan habka dhaqidda saxda ah, guud ahaanna uma nugul qallafsanaanta dhaqidda awgeed.

5. heerkulbeeg wanaagsan iyo iska caabin dhalaaleed oo liita
Iyada oo ay ugu wacan tahay dusha siman ee polyester-ka iyo habaynta dhow ee molecules gudaha, polyesterku waa dharka leh iska caabbinta kulaylka ugu fiican ee ka mid ah dharka fiber synthetic waxayna leedahay sifooyin heerkulbeeg ah.Sidaa darteed, boorsooyinka dharka polyester-ka ah waa inay isku dayaan inay iska ilaaliyaan inay la xiriiraan dabada sigaarka, dhimbilaha, iwm.
;
Nidaamka tolida ee dharka polyesterka, sababtoo ah dhumucyada kala duwan ee fiilooyinka la isticmaalo, waxay sidoo kale loo qaybin karaa noocyo kala duwan oo tilmaamo ah.Tilmaamaha dharka polyester-ka waxaa guud ahaan lagu muujiyay "fineness (D)", iyo ganaaxa waxaa sidoo kale loo yaqaan diidmo, taas oo ah, diidmo.Inta uu bato nambarka D, dhumucdiisuna way sii korodhaa, miisaanka garaamku wuu weyn yahay, wayna ka sii fiicnaanaysaa iska caabbinta xidhashada.Tusaale ahaan, 150D,210D,300D,600D,1000D,1680D,iwm , aasaasiga ah Waxaa loo isticmaalaa sida walxaha ugu muhiimsan ee boorsada dhabarka.
