Chinthu chachikulu cha nsalu yotambasula ya Lycra ndi kusungunuka kwakukulu, komwe kumadziwika kuti zotanuka, zomwe zimatha kutambasula nthawi 4-7 kutalika kwake. Pafupifupi nsalu zonse zamasewera padziko lapansi masiku ano zimagwiritsa ntchito spandex. Makamaka zovala zochitira masewera olimbitsa thupi komanso zosambira. Nsalu ya Lycra ndi nsalu yopangidwa ndi spandex fiber (yachidule ya Spandex polyurethane fiber), yomwe imatchedwanso "pull frame" (matchulidwe achi Cantonese a Lycra) m'madera a Cantonese.

Ku Mainland, nthawi zina amatchedwa "spandex nsalu" mwachindunji. "Lycra" ndi kumasulira kwa liwu lachingerezi LYCRA. Anafufuzidwa bwino ndi Bayer ku Germany mu 1937, ndipo DuPont inayamba kupanga mu 1959. Ndi chizindikiro cholembedwa cha DuPont spandex fiber, chomwe chingasinthe kwambiri The elasticity ndi extensibility ya nsalu, ndi kuchira bwino kwa spandex pambuyo kutambasula ndi zake. ubwino waukulu. Kusiyanitsa ndi ulusi wotanuka wachikhalidwe ndikuti ukhoza kutambasula mpaka 500% ndipo ukhoza kubwezeretsedwanso ku mawonekedwe ake oyambirira.

Mwa kuyankhula kwina, mtundu uwu wa fiber ukhoza kutambasulidwa mosavuta, koma ukhoza kumamatira pamwamba pa thupi la munthu pambuyo pochira, ndipo mphamvu yoletsa pa thupi la munthu ndi yochepa kwambiri. Lycra fiber ikhoza kugwiritsidwa ntchito ndi nsalu iliyonse. Amatchedwa "wochezeka" fiber, kuphatikizapo ubweya, hemp, silika ndi thonje, kuti awonjezere kuyandikira, zotanuka ndi zotayirira za nsalu, ndipo zimamveka bwino pamene zikuyenda. Komanso, Lycra ndi yosiyana ndi ulusi wambiri wa spandex. Ili ndi kapangidwe kake kapadera ndipo sichimamera nkhungu m'malo otsekedwa ndi chinyezi komanso kutentha ikanyowa. Ubwino wake umazindikiridwa ndi anzawo. Pakalipano, malinga ngati zovala zomwe zimatengera Lycra zidzapachikidwa ndi chizindikiro cha makona atatu, chizindikirochi chakhalanso chizindikiro chapamwamba kwambiri.

Nsalu zotambasula za Lycra sizingachepetse. Lycra imatchedwa "wochezeka" fiber, osati chifukwa chakuti imatha kuphatikizidwa bwino ndi ulusi wachilengedwe komanso wopangidwa ndi anthu, komanso imatha kuwonjezera chitonthozo cha nsalu kapena zovala, kudziletsa, ndi ufulu woyenda Ndi utumiki. moyo. Ubwino wa Lycra kutambasula nsalu 1. Kusinthasintha kwambiri

Ikhoza kuonjezera elasticity ya nsalu. Ikhoza kugwiritsidwa ntchito pamodzi ndi mitundu yosiyanasiyana ya ulusi, kaya ndi yachilengedwe kapena yopangidwa ndi anthu, sizingasinthe maonekedwe ndi mawonekedwe a nsalu. Mwachitsanzo, nsalu za ubweya + Lycra sizimangokhala zotanuka, komanso zimakhala bwino, kusunga mawonekedwe, kupukuta ndi kuvala pambuyo pochapa; thonje + Lycra sikuti ili ndi ubwino wa thonje wa thonje wotonthoza ndi kupuma, komanso imaganiziranso thonje Ilibe makhalidwe abwino komanso osavuta kupunduka, zomwe zimapangitsa kuti nsaluyo ikhale yoyenera, yokwanira, yofewa komanso yabwino. Lycra akhoza kuwonjezera ubwino wapadera kwa zovala: chitonthozo chapafupi, ufulu wa kuyenda ndi kusunga mawonekedwe kwa nthawi yaitali.

2. Kugwiritsa ntchito kwakukulu

Lycra itha kugwiritsidwa ntchito ngati nsalu zoluka za thonje, nsalu zaubweya wambali ziwiri, poplin ya silika, nsalu za nayiloni ndi nsalu zosiyanasiyana za thonje.

3. Chitonthozo cha Lycra

M’zaka zaposachedwapa, anthu okonda mafashoni amakhumudwa ndi kutanganidwa ndi mpikisano wa mzindawo. Safuna zovala zimene amazitsatira tsiku lililonse. Ayenera kukhala ogwirizana ndi chitonthozo pamene akusunga zovala zoyenera. Zovala za Lycra zili ndi mawonekedwe omasuka komanso omasuka kuyenda, zomwe zimakwaniritsa zosowa za anthu amasiku ano pazovala.

Lycra fiber ndi ntchito yake

Lycra ili mu mawonekedwe a matt white, translucent kapena translucent filaments ndi fineness of 11 dtex-1880 dtex. Silika wa Lycra wa ma fineness osiyanasiyana amagwiritsidwa ntchito makamaka mu: masitonkeni owonekera; zovala zozungulira (zovala zamkati, zamasewera); masokosi a miyendo; zomangira lamba wopapatiza; nsalu zoluka zoluka zamkati mwa akazi ndi zovala zosambira; mankhwala (zidutswa za mulu, mabandeji, etc.); nsapato, etc.
