Fibre polyester, bakunze kwita "polyester".Nibikoresho bya sintetike byabonetse kubizunguruka polyester yabonetse na polycondensation ya acide dibasic aside na alcool ya dihydric.Nibikoresho bya polymer kandi nubwoko bunini bwa fibre synthique muri iki gihe.Imyenda ya polyester ikoreshwa cyane mubikorwa byo gutunganya imizigo, naho imyenda ya polyester ikoreshwa mubicuruzwa byinshi.Kubwibyo, niba ubonye "polyester fibre" yanditse ku bisobanuro bifatika byerekana tagi yinyuma mugihe kizaza, noneho igikapu gikozwe mumyenda ya polyester.
Imyenda ya polyester nimwe mumyenda isanzwe yimifuka.Ifite imyunvire myiza yimitsi, kugumana imiterere, imbaraga nyinshi nubushobozi bwo gukira bworoshye, kurwanya inkari, nta cyuma, umusatsi udafite inkoni nibindi byiza.
1. Elastique yimyenda ya polyester nibyiza
Imyenda ya polyester ifite imbaraga nyinshi nubushobozi bwo kugarura ibintu byoroshye, kandi ifite imbaraga zo kurwanya iminkanyari no kugumana imiterere.Byakoreshejwe mugukora ibikapu.Isakoshi yarangiye irakomeye kandi irwanya kwambara.Igitambara nticyahinduwe muburyo bwimbaraga ziva hanze, cyihanganira inkeke, kandi ahanini ntigikeneye ibyuma., paki yumubiri imiterere izaba igereranije, itatu-yuburyo kandi bwiza.Mugukoresha bisanzwe, ibikapu bikozwe mumyenda ya polyester biraramba kandi ntabwo byoroshye guhinduka.
2. Kurwanya urumuri rwiza
Umucyo ni uwakabiri nyuma ya acrylic (ubwoya bwubukorikori).Umuvuduko ukabije wimyenda ya polyester iruta iy'imisemburo ya acrylic, kandi kwihuta kwayo kuruta ubw'imyenda ya fibre naturel.Cyane cyane umuvuduko mwinshi inyuma yikirahure nibyiza cyane, hafi kuringaniza na acrylic.Ibicuruzwa byo mu gikapu bikozwe mu mwenda wa polyester ntabwo bikunda guhura nikirere, kwinjiza no kuvunika iyo bikoreshejwe hanze.
3. Irangi ribi
Nubwo imyenda ya polyester ifite irangi rike, ifite amabara meza yihuta.Iyo bimaze gusiga irangi neza, ntabwo bizashira byoroshye, kandi ntibizashira mugihe cyo gukaraba.Yakozwe mubicuruzwa byapakiye, kandi umwenda ntiworoshye gucika nyuma yo gukoresha igihe kirekire, kandi ingaruka zo kugumana amabara nibyiza cyane.
4. Hygroscopicity mbi
Hygroscopicity ya polyester iba ifite intege nke kurusha iya nylon, bityo rero umwuka wo mu kirere ntumeze neza nka nylon, ariko ni ukubera ko biterwa na hygroscopicitike yimyenda ya polyester ko imyenda ya polyester yoroshye gukama nyuma yo gukaraba, nimbaraga zimyenda kugabanuka cyane, ntabwo rero byoroshye guhindura.Ibicuruzwa byakozwe mu gikapu bikoresha uburyo bwo gukaraba neza, kandi muri rusange ntibishobora guhinduka bitewe no gukaraba.
5. Thermoplastique nziza hamwe no kurwanya gushonga nabi
Bitewe n'ubuso bworoshye bwa polyester hamwe no gutondekanya hafi ya molekile y'imbere, polyester nigitambara gifite imbaraga nziza zo guhangana nubushyuhe bwiza mumyenda ya fibre synthique kandi ifite imiterere ya thermoplastique.Kubwibyo, ibikapu bya polyester bigomba kugerageza kwirinda kwirinda itabi, itabi, nibindi.
Muburyo bwo kuboha imyenda ya polyester, kubera ubunini butandukanye bwa fibre yakoreshejwe, birashobora kandi kugabanywa muburyo butandukanye bwihariye.Ibisobanuro by'imyenda ya polyester bigaragazwa na "ubwiza (D)", kandi ubwiza nabwo bwitwa guhakana, ni ukuvuga guhakana.Umubare munini wa D, umubyimba mwinshi wimyenda, nuburemere bwa garama, nuburyo bwiza bwo kwihanganira kwambara.Kurugero, 150D, 210D, 300D, 600D, 1000D, 1680D, nibindi bikunze gukoreshwa mubitambaro bya polyester, nka 150D, 210D nizindi myenda ntoya yo guhakana, inyinshi murizo zikoreshwa mugukora udukapu, 300D no hejuru yimyenda idasanzwe. , shingiro Byakoreshejwe nkibikoresho byingenzi byinyuma.
