Pali ulusi wambiri wosoka pamsika.Mwa iwo, mikanda yosokera ya poliyesitala ndi ma nyon fiaments ndi mitundu iwiri yodziwika bwino yosokera Kodi mukudziwa kusiyana kwake?Kenako tikuwonetsani kusiyana kwa ulusi wa polyester ndi ulusi wa nayiloni.
Za polyester
Polyester ndi mtundu wofunikira mu ulusi wopangira ndipo ndi dzina lamalonda la ulusi wa poliyesitala ku China.Ulusi wopanga polima wopangidwa ndi esterification kapena transesterification ndi polycondensation wa PTA kapena DMT ndiMEG-Polyethylene terephthalate (PET).Ndi ulusi wopangidwa ndi kupota ndi pambuyo pa chithandizo.
Za nayiloni
Nylon inapangidwa ndi Carothers, wasayansi wa ku America, ndi gulu lofufuza lotsogoleredwa ndi iye.Ndiwo ulusi woyamba padziko lapansi.Nayiloni ndi mtundu wa ulusi wa polyamide.Maonekedwe a nayiloni asintha kwambiri zinthu zopangidwa ndi nsalu.Kaphatikizidwe kake ndikupambana kwakukulu mumakampani opanga ma fiber ndipo ndi gawo lofunikira kwambiri pakupanga ma polymer chemistry.
Kusiyana kwa Magwiridwe
Kuchita kwa nayiloni
Zamphamvu, zosavala, zokhala patsogolo pakati pa ulusi uliwonse.Kukana kwake kuvala ndi nthawi 10 za ulusi wa thonje ndi ulusi wouma wa viscose, ndi nthawi 140 za ulusi wonyowa.Chifukwa chake, kulimba kwake ndikwabwino kwambiri.The elastic and elastic recovery of thensalu ya nayiloni ndizabwino kwambiri, koma zimapunduka mosavuta ndi mphamvu yakunja, kotero kuti nsaluyo imakwinya mosavuta panthawi yovala.Ndiwopanda mpweya wabwino komanso wosavuta kupanga magetsi osasunthika.
Magwiridwe a Polyester
Mphamvu zapamwamba
Mphamvu zazifupi za ulusi ndi 2.6 mpaka 5.7 cN/dtex, ndipo ulusi wamphamvu kwambiri ndi 5.6 mpaka 8.0 cN/dtex.Chifukwa cha kuchepa kwa hygroscopicity, mphamvu yake yonyowa imakhala yofanana ndi mphamvu youma.Mphamvu yamphamvu ndi nthawi 4 kuposa ya nayiloni ndi nthawi 20 kuposa viscose.
Elasticity yabwino
Kutanuka kumakhala pafupi ndi ubweya wa ubweya, pamene utatambasulidwa ndi 5% mpaka 6%, ukhoza kuchira.Kukaniza makwinya kumaposa ulusi wina, ndiko kuti, nsaluyo simakwinya, ndipo kukhazikika kwa mawonekedwe ndikwabwino.Modulus ya elasticity ndi 22 mpaka 141 cN/dtex, yomwe ndi 2 mpaka 3 kuposa ya nayiloni.
Mayamwidwe abwino amadzi
Good akupera kukana.Kuvala kukana kwa poliyesitala ndi kwachiwiri kwa nayiloni.Ndibwino kuposa ulusi wina wachilengedwe komanso wopangidwa, ndipo kukana kwake kowala ndi kwachiwiri kwa acrylic fiber.
Kusiyana pakati pa kugwiritsa ntchito polyester ndi nayiloni
Poganizira za hygroscopicity, nsalu ya nyion ndi mitundu yabwino pansalu zopanga, kotero kuti masewera opangidwa ndi nayiloni ndi abwino kuvala kuposa ma polyester.lt ili ndi sputum yabwino komanso kukana kwa dzimbiri, koma kutentha ndi kuwala sikokwanira.Kutentha kwa roning kuyenera kuchepetsedwa pansi pa 140 ℃C. Samalani zopangira zochapa ndi kukonza, kuti musawononge nsalu.Nsalu ya nayiloni ndi nsalu yopepuka, yomwe imangokhala ited afe polypropylene ndi nsalu za acrylic mu nsalu zopangira.Choncho, ndi oyenera kukwera mapiri ndi nsalu yozizira.
Nsalu ya polyester imakhala ndi hygroscopicity yocheperako ndipo imakhala yotentha mukavala.Ndizosavuta kunyamula magetsi osasunthika ndi fumbi lotayirira, zomwe zimakhudza mawonekedwe ndi chitonthozo.Komabe, ndizosavuta kuumitsa mukatsuka, ndipo sizimapunduka.Polyester ndiye nsalu yabwino kwambiri yosamva kutentha munsalu zopanga.Malo osungunuka ndi 260 ° C ndipo kutentha kwa ironing kungakhale 180 ° C. Ili ndi perfomance ya thermoplastic ndipo imatha kupangidwa kukhala siketi yotsekemera yokhala ndi zokopa zazitali.
Nsalu ya polyester ilibe kusungunuka bwino, ndipo ndiyosavuta kupanga mabowo ngati mwaye kapena Mars.Choncho, kuvala nsalu za polyester kuyenera kupeŵa kukhudzana ndi ndudu za ndudu, zopsereza, etc. Nsalu za polyester zimakhala ndi makwinya abwino komanso kusunga mawonekedwe, choncho ndizoyenera zovala zakunja.
