Iimpawu zomsonto wepolyester wokuqina ziyamangalisa, ezinokushwankathelwa ngolu hlobo lulandelayo:
1. Umsonto wepolyester oqinileyo unamandla aphezulu.Amandla amafutshane efayibha yi-2.6 ~ 5.7 cn/dtex, kwaye amandla aphezulu efayibha yi-5.6 ~ 8.0 cn/dtex.Ngenxa ye-hygroscopicity ephantsi, amandla ayo amanzi ngokusisiseko ayafana namandla ayo omileyo.Amandla empembelelo ngamaxesha e-4 aphezulu kunenylon kunye namaxesha angama-20 aphezulu kunefiber viscose.
2. Umsonto wepolyester owomelele kakhulu une-elasticity entle.I-elasticity isondele kuboya, kwaye ingaphantse ibuyele kwimeko yesiqhelo xa isoluliwe nge-5% ~ 6%.Ukuxhathisa i-crease kungcono kunezinye iifayibha, oko kukuthi, ilaphu alishwabenanga kwaye linozinzo olufanelekileyo.I-elastic modulus yi-22 ~ 141 cn/dtex, eyi-2 ~ 3 ngokuphindwe ka-3 ngaphezulu kwe-nylon.Ilaphu lePolyester linamandla aphezulu kunye nekhono lokubuyisela i-elastic, ngoko ke, liqinile kwaye lihlala ixesha elide, liyamelana nemibimbi kwaye alina-ayina.
3. I-polyester filament yamandla aphezulu I-polyester enganyangekiyo ubushushu yenziwa yi-melt spinning, kwaye i-fiber ebunjiweyo inokufudunyezwa kwaye inyibilike kwakhona, eye-fiber thermoplastic.Indawo yokunyibilika yepolyester iphezulu kakhulu, kodwa umthamo wobushushu obuthile kunye nokuhanjiswa kwe-thermal zombini zincinci, ngoko ke ukumelana nobushushu kunye nokufakwa kwe-thermal yefiber yepolyester kuphezulu.Yeyona fiber ilungileyo yokwenziwa.
4. Umsonto wepolyester womelele kakhulu une-thermoplasticity elungileyo kunye nokumelana nokunyibilika okubi.Ngenxa yobuso bayo obugudileyo kunye nolungelelwaniso oluluqilima lweeamolekyuli zangaphakathi, ipolyester yeyona ilaphu elikwaziyo ukumelana nobushushu kumalaphu e-synthetic fiber, ane-thermoplasticity kwaye anokusetyenziswa ukwenza iziketi eziphothiweyo, kwaye iipleyiti zihlala ixesha elide.Ngelo xesha, ukuxhatshazwa kwe-melting ye-polyester kubi, kwaye kulula ukwenza imingxuma xa udibana ne-soot, i-sparks, njl.
5. Umsonto wepolyester oqinileyo unokumelana nokunxiba kakuhle.Ukuxhatshazwa kwe-abrasion kukwesibini kuphela kwi-nylon ene-abrasion resistance resistance, engcono kunezinye iifayili zendalo kunye neentambo zokwenziwa.
6. Umsonto wepolyester oqinileyo unokumelana nokukhanya okulungileyo.Ukukhawuleza okukhanyayo kukwesibini kuphela kwi-acrylic.Ukukhanya okukhanyayo kwelaphu le-polyester kungcono kune-fiber ye-acrylic, kwaye ukukhawuleza kwayo ukukhanya kungcono kunokwelaphu le-fiber yendalo.Ngokukodwa ngasemva kweglasi, ukukhanya okukhanyayo kuhle kakhulu, kuphantse kulingane ne-acrylic fiber.
7. Umsonto wepolyester owomelele kakhulu awuxhathisi kukuhlwa.Ukumelana ne-bleaching agents, i-oxidants, i-hydrocarbons, ii-ketones, iimveliso zepetroleum kunye ne-inorganic acids.Iyakwazi ukuxhathisa i-alkali kwaye ingoyiki ukungunda, kodwa inokuboliswa yi-alkali eshushu.Ikwanayo ne-asidi eyomeleleyo kunye nokumelana ne-alkali kunye nokumelana ne-ultraviolet.
8. Ukudaya okungalunganga, kodwa ukukhawuleza kombala okulungileyo, akukho lula ukucima.Ngenxa yokuba akukho qela lithile lokudaya kwikhonkco le-molecular ye-polyester, kwaye i-polarity incinci, kunzima ukudaya, kwaye ukudaya akubi, ngoko ke iimolekyuli zedayi azilula ukungena kwifiber.
9. Umsonto we-polyester onamandla aphezulu une-hygroscopicity engalunganga, imvakalelo ye-sultry xa igugile, kwaye kwangaxeshanye, ixhomekeke kumbane ongatshintshiyo kunye nokungcoliswa kothuli, okuchaphazela ubuhle kunye nentuthuzelo.Nangona kunjalo, kulula ukuyomisa emva kokuhlanjwa, kwaye amandla ayo amanzi anqabile kwaye ayikhubeki, ngoko inokusebenza kakuhle okuhlambekayo kunye nokunxiba.
Isishwankathelo:
Ilaphu elenziwe ngesilika ye-polyester ephezulu ineenzuzo zokomelela okulungileyo, ukuguda kunye nokuqina, ukuhlanjwa lula kunye nokomisa ngokukhawuleza, kodwa inezinto ezingathandekiyo ezifana nesandla esinzima, ukubamba kakubi, ukucwebezela okuthambileyo, ukungahambi kakuhle komoya kunye nokufunxa ukufuma.Xa kuthelekiswa namalaphu e-silika okwenene, umsantsa mkhulu ngakumbi, ngoko ke kuyimfuneko ukulinganisa isilika kwisakhiwo sesilika kuqala ukuphelisa ukungonakali kokunganxibi kakuhle.
