1.Spandex CHIKWANGWANI
Spandex CHIKWANGWANI (chotchedwa PU CHIKWANGWANI) ndi chamtundu wa polyurethane wokhala ndi elongation yayikulu, modulus yotsika yotanuka komanso kuchira kwamphamvu kwambiri.Kuphatikiza apo, spandex imakhalanso ndi kukhazikika kwamphamvu kwamankhwala komanso kukhazikika kwamafuta.Imagonjetsedwa ndi mankhwala kuposa silika wa latex.Kuwonongeka, kutentha kofewetsa kumakhala pamwamba pa 200 ℃.Ulusi wa Spandex umalimbana ndi thukuta, madzi a m'nyanja ndi zowuma zosiyanasiyana komanso zoteteza ku dzuwa.Kuwonekera kwa dzuwa kwa nthawi yayitali kapena chlorine bleach kumathanso kuzimiririka, koma kuchuluka kwa kuzimiririka kumasiyana mosiyanasiyana kutengera mtundu wa spandex.Zovala zopangidwa ndi nsalu zokhala ndi spandex zimakhala ndi mawonekedwe abwino, kukula kokhazikika, osapanikizika komanso kuvala bwino.Kawirikawiri, 2% mpaka 10% yokha ya spandex ikhoza kuwonjezeredwa kuti apange zovala zamkati zofewa komanso pafupi ndi thupi, zomasuka komanso zokongola, kupanga masewera olimbitsa thupi kuti azikhala ofewa komanso akuyenda momasuka, ndikupanga mafashoni ndi zovala zodzikongoletsera kukhala ndi drape yabwino, kusunga mawonekedwe ndi mafashoni.Chifukwa chake, spandex ndi ulusi wofunikira kwambiri pakupanga nsalu zotanuka kwambiri.
2.Polytrimethylene terephthalate fiber
Polytrimethylene terephthalate CHIKWANGWANI (PTT CHIKWANGWANI mwachidule) ndi mankhwala atsopano mu banja polyester.Ndi ya polyester fiber ndipo ndi chinthu chodziwika bwino cha polyester PET.PTT CHIKWANGWANI ali ndi makhalidwe onse a poliyesitala ndi nayiloni, wofewa dzanja, zabwino zotanuka kuchira, zosavuta utoto pansi pa kupsyinjika yachibadwa, kuwala mtundu, wabwino dimensional bata la nsalu, oyenera kwambiri munda wa zovala.Ulusi wa PTT ukhoza kusakanikirana, kupindika ndi kulumikiza ndi ulusi wachilengedwe kapena ulusi wopangidwa monga ubweya ndi thonje, ndipo ukhoza kugwiritsidwa ntchito munsalu zolukidwa ndi nsalu zoluka.Kuphatikiza apo, ulusi wa PTT ungagwiritsidwenso ntchito mu nsalu za mafakitale ndi madera ena, monga kupanga makapeti, zokongoletsera, ukonde ndi zina zotero.PTT CHIKWANGWANI ali ndi ubwino spandex zotanuka nsalu, ndipo mtengo ndi wotsika kuposa spandex zotanuka nsalu.Ndi fiber yatsopano yolonjeza.
3.T-400 CHIKWANGWANI
T-400 CHIKWANGWANI ndi mtundu watsopano wa zotanuka CHIKWANGWANI zopangidwa ndi DuPont pofuna kuchepetsa spandex ulusi mu ntchito nsalu.T-400 si wa banja la spandex.Imazunguliridwa mbali ndi mbali ya ma polima awiri, PTT ndi PET, ndi mitengo yocheperako yosiyana.Ndi fiber yophatikizika mbali ndi mbali.Imathetsa mavuto ambiri a spandex monga utoto wovuta, kukhazikika kopitilira muyeso, kuluka kovutirapo, kukula kosakhazikika kwa nsalu ndi kukalamba kwa spandex pakagwiritsidwa ntchito.
Nsalu zopangidwa ndi izo zili ndi makhalidwe awa:
(1) The elasticity ndi yosavuta, yabwino komanso yolimba;(2) Nsaluyo ndi yofewa, yolimba ndipo imakhala yabwino;(3) Pamwamba pa nsaluyo ndi lathyathyathya ndipo amakana makwinya;(4) Kuyamwa kwachinyezi ndi kuyanika mwachangu, kumva bwino m'manja;(5) Kukhazikika kwabwino komanso kosavuta kunyamula.
T-400 ikhoza kusakanikirana ndi ulusi wachilengedwe ndi ulusi wopangidwa ndi anthu kuti ukhale wolimba komanso wofewa, mawonekedwe a nsalu zosakanikirana zimakhala zoyera komanso zosalala, mawonekedwe a zovala amamveka bwino, zovala zimatha kukhalabe ndi mawonekedwe abwino pambuyo pochapa mobwerezabwereza, Nsalu imakhala ndi mtundu wabwino wothamanga, wosavuta kuzimiririka, wokhalitsa Wovala ngati watsopano.Pakalipano, T-400 imagwiritsidwa ntchito kwambiri mu mathalauza, denim, masewera, zovala za amayi apamwamba ndi zina chifukwa cha ntchito yake yovala bwino.
Njira yoyatsira ndiyo kuzindikira mtundu wa ulusi pogwiritsa ntchito kusiyana kwa mankhwala a ulusi wosiyanasiyana komanso kusiyana kwa mawonekedwe oyaka opangidwa.Njirayi ndikutenga mtolo wawung'ono wa zitsanzo za ulusi ndikuwotcha pamoto, kuyang'anitsitsa makhalidwe oyaka a ulusi ndi mawonekedwe, mtundu, kufewa ndi kuuma kwa zotsalirazo, ndipo nthawi yomweyo kununkhiza fungo lopangidwa ndi iwo.
Kuwotcha makhalidwe atatu zotanuka ulusi
