Masiku ano, ulusi wa polyester ndi gawo lalikulu la nsalu zomwe anthu amavala.Kuphatikiza apo, pali ulusi wa acrylic, ulusi wa nayiloni, spandex, ndi zina zotero. Ulusi wa polyester, womwe umadziwika kuti "polyester", womwe unapangidwa mu 1941, ndiwo mitundu yambiri yamitundu yopangira.Ubwino waukulu wa ulusi wa poliyesitala ndikuti umakhala ndi kukana bwino kwa makwinya ndi kusunga mawonekedwe, mphamvu yayikulu komanso kuthekera kochira zotanuka, ndipo ndi yolimba komanso yolimba, yolimbana ndi makwinya komanso osasiya kusita, komanso samamatira ubweya, chomwe ndichifukwa chake chachikulu. anthu amakono amakonda kugwiritsa ntchito.
Ulusi wa poliyesitala ukhoza kuwomba mu ulusi wa poliyesitala komanso ulusi wa poliyesitala.Ulusi waukulu wa poliyesitala, womwe ndi ulusi wa poliyesitala, ukhoza kugawidwa mu ulusi wa thonje (38mm muutali) ndi ulusi waubweya waubweya (utali wa 56mm) wophatikiza ndi ulusi wa thonje ndi ubweya.Polyester filament, monga chovala chovala, nsalu yake imatha kukhala ndi makwinya opanda chitsulo ndi chitsulo mutatsuka.
Ubwino wa polyester:
1. Imakhala ndi mphamvu zambiri komanso mphamvu yobwezeretsa zotanuka, motero imakhala yolimba komanso yolimba, yolimbana ndi makwinya komanso yopanda chitsulo.
2. Kukana kwake kuwala ndikwabwino.Kuphatikiza pa kukhala wocheperapo kuposa acrylic fiber, kukana kwake kuwala kuli bwino kuposa nsalu zachirengedwe zachirengedwe, makamaka pambuyo pa ulusi wa galasi, kuwala kwake kumakhala kofanana ndi kwa acrylic fiber.
3. Nsalu ya polyester (polyester) imakhala yabwino kukana mankhwala osiyanasiyana.Acid ndi alkali siziwononga pang'ono.Pa nthawi yomweyo, si mantha nkhungu ndi njenjete.
Zoyipa za polyester:
1. Kusauka kwa hygroscopicity, kufooka kwa hygroscopicity, kumveka kosavuta kumva, kusungunuka kosasungunuka, kosavuta kuyamwa fumbi, chifukwa cha kapangidwe kake;
2. Kusakwanira kwa mpweya, kosavuta kupuma;
3. Kupaka utoto ndikovuta, ndipo kumafunika kudayidwa ndi utoto wobalalika pa kutentha kwakukulu.
Nsalu ya poliyesitala ndi ya ulusi wosapangidwa mwachilengedwe, womwe umagwiritsidwa ntchito kwambiri munsalu za autumn ndi yozizira, koma sizoyenera kuvala zovala zamkati.Polyester ndi yolimbana ndi asidi.Gwiritsani ntchito zotsukira zosalowerera kapena za acidic poyeretsa, ndipo zotsukira zamchere zimafulumizitsa kukalamba kwa nsalu.Kuphatikiza apo, nsalu za polyester nthawi zambiri sizifuna kusita.Kutentha kwapansi kwa nthunzi kuli bwino.
Tsopano opanga zovala zambiri nthawi zambiri amaphatikiza kapena kuphatikizira poliyesitala ndi ulusi wosiyanasiyana, monga poliyesitala wa thonje, poliyesita ya ubweya, ndi zina zotero, zomwe zimagwiritsidwa ntchito kwambiri muzovala zosiyanasiyana ndi zinthu zokongoletsera.Kuphatikiza apo, ulusi wa poliyesitala ungagwiritsidwe ntchito m'makampani opanga lamba, hema, chinsalu, chingwe, ukonde wophera nsomba, ndi zina zambiri, makamaka chingwe cha poliyesitala chomwe chimagwiritsidwa ntchito pamatayala, chomwe chili pafupi ndi nayiloni.Polyester angagwiritsidwenso ntchito ngati zakuthupi insulating magetsi, asidi kugonjetsedwa fyuluta nsalu, mankhwala mafakitale nsalu, etc.
Ndi ulusi uti womwe ungaphatikizidwe ndi ulusi wa polyester ngati nsalu, ndipo ndi nsalu ziti zomwe zimagwiritsidwa ntchito kwambiri?
Ulusi wa polyester uli ndi mphamvu zambiri, modulus yapamwamba, kuyamwa kwamadzi otsika, ndipo amagwiritsidwa ntchito kwambiri ngati nsalu zaboma komanso zamakampani.Monga nsalu, ulusi wa polyester ukhoza kukhala wopota kapena wosakanizidwa ndi ulusi wina, kaya ndi ulusi wachilengedwe monga thonje, hemp, ubweya, kapena ulusi wina wamankhwala monga viscose fiber, acetate fiber, polyacrylonitrile fiber, etc.
Monga thonje, ubweya wa ubweya ndi nsalu zonga nsalu zopangidwa ndi ulusi woyera kapena wosakanizidwa wa polyester nthawi zambiri zimakhala ndi zoyambira zabwino kwambiri za ulusi wa poliyesitala, monga kukana makwinya ndi kukana abrasion.Komabe, zina mwazolakwika zawo zoyambirira, monga kusayamwa bwino kwa thukuta ndi kuloleza, komanso kusungunuka mosavuta m'mabowo mukakumana ndi zowala, zimatha kuchepetsedwa ndikuwongoleredwa pang'onopang'ono ndi kusakanikirana kwa ulusi wa hydrophilic.
Ulusi wopotoka wa polyester (DT) umagwiritsidwa ntchito makamaka kuluka silika zosiyanasiyana monga nsalu, ndipo ukhozanso kulukidwa ndi ulusi wachilengedwe kapena ulusi wamankhwala, komanso ulusi wa silika kapena mankhwala ena.Nsalu zophatikizikazi zimakhala ndi maubwino angapo a polyester.
Mitundu yayikulu ya ulusi wa poliyesitala yomwe idapangidwa ku China m'zaka zaposachedwa ndi ulusi wopangidwa ndi poliyesitala (makamaka ulusi wochepa kwambiri wa DTY), womwe ndi wosiyana ndi ulusi wamba chifukwa ndi wokwera kwambiri, wonyezimira, wonyezimira, wofewa, komanso wokhala ndi zotanuka kwambiri. kukula (mpaka 400%).
Zovala zokhala ndi ulusi wopangidwa ndi polyester zimakhala ndi mawonekedwe osungira bwino kutentha, zofunda zabwino ndi zotchingira, komanso zowala zofewa, monga nsalu zaubweya, malaya, malaya ndi nsalu zosiyanasiyana zokongoletsera, monga makatani, nsalu zapa tebulo, nsalu za sofa, ndi zina zambiri.
