Kodi spandex ndi nsalu yotani?
Spandex ndi mtundu wa ulusi wa polyurethane.Chifukwa cha kusinthasintha kwake, umadziwikanso kuti elastic fiber, yomwe imagwiritsidwa ntchito kwambiri munsalu za zovala.Makhalidwe akuluakulu a nsalu ya spandex ndi:(1) Kutanuka kwa spandex ndikokwera kwambiri.Kawirikawiri, mankhwala sagwiritsa ntchito 100% polyurethane, ndipo nthawi zambiri, 5% mpaka 30% ya polyurethane imasakanizidwa mu nsalu, zomwe zimapangitsa kuti mitundu yosiyanasiyana ya nsalu za spandex imadzitamande 15% mpaka 45% ya elasticity yabwino. 2) Nsalu ya spandex nthawi zambiri imapangidwa ndi ulusi wambiri.Zikutanthauza kuti spandex ndiye pachimake ndi ulusi wina (monga nayiloni, poliyesitala, etc.) ndi kotekisi kupanga kuphimba ulusi zotanuka nsalu, amene amadzitama bwino kusinthasintha kwa thupi ndipo ndi yoyenera zopangira zothina, osapereka tanthauzo. kupanikizika.
(3) Maonekedwe ndi mavalidwe a nsalu zotanuka za spandex ndizofanana ndi zazinthu zonga ngati nsalu yake yotchinga yakunja.
Kodi nsonga zowala za zovala zopangidwa ndi spandex ndi ziti?
1. Ubwino waukulu wa nsalu ya spandex ndi elasticity yake yabwino, yomwe imatha kutambasulidwa nthawi 5 mpaka 8 popanda ukalamba.Spandex singalukidwe yokha ndipo nthawi zambiri imalukidwa ndi zida zina.Zomwe zili mu spandex ndi pafupifupi 3 mpaka 10%, ndipo mu nsalu zosambira zimatha kufika 20%.
2. Spandex CHIKWANGWANI ndi ulusi wopangidwa wokhala ndi elongation yayikulu panthawi yopuma (kupitilira 400%), modulus yotsika komanso kuthamanga kwapamwamba kwambiri.Ndi dzina la malonda aku China la multi-block polyurethane fiber, yomwe imadziwikanso kuti zotanuka.Spandex ili ndi elongation yayikulu (500% mpaka 700%), modulus otsika (200% elongation, 0.04 mpaka 0.12 g / denier) komanso kuchira kokulirapo (200% elongation, 95% mpaka 99%).Maonekedwe ake akuthupi ndi makina amafanana kwambiri ndi waya wa latex wachilengedwe kupatula mphamvu zake zazikulu.Imalimbana kwambiri ndi kuwonongeka kwa mankhwala kuposa silika wa latex, ndipo imakhala ndi kukhazikika kwamafuta pang'ono ndi kutentha kofewa pafupifupi 200 ℃ kapena kupitilira apo.Utoto wambiri ndi zomalizitsa zomwe zimagwiritsidwa ntchito mu ulusi wopangira komanso zachilengedwe ndizoyeneranso kuzonda ndikumaliza spandex.Spandex imagonjetsedwa ndi thukuta, madzi a m'nyanja ndi zotsukira zosiyanasiyana zowuma komanso zoteteza dzuwa.Zizimiririkanso ndi kutenthedwa kwa nthawi yayitali ndi kuwala kwa dzuwa kapena chlorine bleach, koma kuchuluka kwa kuzimiririka kumasiyana kwambiri ndi mtundu wa spandex.Spandex ndi ulusi wa polyurethane.Chifukwa cha kukhuthala kwake, amadziwikanso kuti elastic fiber, yomwe yakhala ikugwiritsidwa ntchito kwambiri mu nsalu za zovala zomwe zimakhala ndi makhalidwe monga kutsekemera kwambiri.Nsalu ya Spandex imagwiritsidwa ntchito makamaka popanga zothina, zovala zamasewera, zomangira zoteteza komanso zomangira.Mitundu yake molingana ndi zosowa zogwiritsidwa ntchito, imatha kugawidwa mu nsalu zotanuka, nsalu zotanuka komanso zotanuka komanso zotanuka.
Makhalidwe a Spandex Fiber Fabric ndi Kugwiritsa Ntchito Spandex
Spandex ndi mtundu wa ulusi wa polyurethane.Chifukwa cha kusinthasintha kwake, umadziwikanso kuti elastic fiber, yomwe imagwiritsidwa ntchito kwambiri munsalu za zovala.
1. Makhalidwe akuluakulu a nsalu ya spandex fiber
(1) Kutanuka kwa spandex ndikokwera kwambiri.Nthawi zambiri, mankhwalawa sagwiritsa ntchito 100% polyurethane, ndipo nthawi zambiri, 5% mpaka 30% ya polyurethane imasakanizidwa munsalu, zomwe zimapangitsa kuti mitundu yosiyanasiyana ya nsalu za spandex imadzitamande 15% mpaka 45% ya elasticity yabwino.
(2) Nsalu ya spandex nthawi zambiri imakhala yopangidwa ndi ulusi wambiri.Zikutanthauza kuti spandex ndiye pachimake ndi ulusi wina (monga nayiloni, poliyesitala, etc.) ndi kotekisi kupanga kuphimba ulusi zotanuka nsalu, amene amadzitama bwino kusinthasintha kwa thupi ndipo ndi yoyenera zopangira zothina, osapereka tanthauzo. kupanikizika.
(3) Maonekedwe ndi mavalidwe a nsalu zotanuka za spandex ndizofanana ndi zazinthu zonga ngati nsalu yake yotchinga yakunja.
2. Kugwiritsa ntchito spandex
(1) Ulusi wa Spandex ungagwiritsidwe ntchito popanga zovala zomwe zimatha kutambasulidwa kuti zikwaniritse zofunikira za chitonthozo.Mwachitsanzo: Zovala zamasewera, zovala zolimbitsa thupi ndi zolimbitsa thupi, suti yodumphira pansi, zosambira, zosambira zamasewera, zovala za basketball, bra ndi lamba wapakhosi, mathalauza otsetsereka, zovala za disco, jeans, mathalauza wamba, masokosi, zotenthetsera miyendo, matewera. , mathalauza othina, lamba, zovala zamkati, majumpha, zovala zothina pafupi ndi spandex, mabandeji ovina aamuna ovina, zovala zoteteza pochita opaleshoni, zovala zodzitetezera zomwe zimagwiritsidwa ntchito ndi magulu othandizira, manja afupiafupi pokwera njinga, vest yolimbana, suti ya boti, zovala zamkati. , zovala zogwirira ntchito, zovala zapamwamba, brassiere, zokongoletsera zapakhomo, pilo ya mikanda yaying'ono, ndi zina.
(2) Spandex sagwiritsidwa ntchito kawirikawiri pazovala wamba.Ku North America, amagwiritsidwa ntchito mochepa pa zovala za amuna komanso pa zovala za akazi.Chifukwa zovala za akazi zimafunika kukhala pafupi kwambiri ndi thupi.Pogwiritsidwa ntchito, idzaphatikizidwa ndi ulusi wina wambiri monga thonje ndi polyester kuti muchepetse gloss.
