Zovala zamkati ndi chovala chomwe chili pafupi ndi khungu la munthu, choncho kusankha nsalu ndikofunika kwambiri.Makamaka pakhungu lovuta kapena lodwala, ngati chovala chamkati sichinasankhidwe bwino, chikhoza kuvulaza thupi la munthu.
Nsaluyo imalukidwa ndi ulusi ndipo ulusiwo umapangidwa ndi ulusi.Choncho, zizindikiro za nsalu zimagwirizana kwambiri ndi ulusi womwe umapanga nsalu.Nthawi zambiri, ulusi umagawidwa kukhala ulusi wachilengedwe komanso ulusi wamankhwala.Ulusi wachilengedwe umaphatikizapo thonje, hemp, silika, ubweya ndi zina zotero.Ulusi wamankhwala umaphatikizapo ulusi wobwezeretsedwanso komanso ulusi wopangira.Chingwe chobwezerezedwanso chimakhala ndi ulusi wa viscose, ulusi wa acetate ndi zina zotero.Synthetic fiber imakhala ndi gudumu la polyester, acrylic fiber, nayiloni ndi zina zotero.Pakali pano, nsalu zachikhalidwe zamkati zimapangidwa makamaka ndi thonje, silika, hemp, viscose, polyester,nsalu ya nayiloni, ulusi wa nayiloni, nsalu ya nayiloni ndi zina zotero.
Pakati pa ulusi wachilengedwe, thonje, silika ndi hemp ndi hygroscopic kwambiri komanso kupuma, ndipo ndi nsalu zabwino zamkati.Komabe, ulusi wachilengedwe umakhala ndi mawonekedwe osakhazikika komanso otambasuka.Mwa kuphatikiza ulusi wachilengedwe ndi ulusi wamankhwala, pogwiritsa ntchito chiŵerengero chosakanikirana bwino, kapena kugwiritsa ntchito ulusi wosiyana m'madera osiyanasiyana a nsalu, zotsatira za mitundu iwiri ya ulusi zingakhale zopindulitsa.Choncho, pali zosankha zambiri za nsalu zamkati, monga nsalu zolimba za nayiloni,ozizira kumva nayiloni thonje,, Tambasulani ulusi wa nayiloni kwa zovala zamkati, nsalu za nayiloni zamkati ndi zina zotero.Mwachitsanzo, kapu ya bra imapangidwa ndi thonje la hygroscopic, pomwe chingwe chakumbali chimapangidwa ndi nsalu zotanuka za ulusi wamankhwala.Pakalipano, zovala zamkati zambiri zimapangidwa ndi zigawo ziwiri.Chosanjikiza pafupi ndi khungu chimapangidwa ndi ulusi wachilengedwe, ndipo pamwamba pake amapangidwa ndi lace yokongola yamankhwala, yomwe imakhala yokongola komanso yabwino.
Pali njira ziwiri zothandiza zodziwira nsalu posankha zovala zamkati.Imodzi ndi njira yozindikira zomverera, ina ndi njira yozindikira zizindikiro.
Sensory Recognition Njira
Kuzindikirika kwamalingaliro kumafunikira chidziwitso, koma sikovuta kukwaniritsa.Malingana ngati malo ogulitsa nthawi zonse amakhudza mwadala nsalu zosiyanasiyana, pakapita nthawi padzakhala zopindulitsa.Ulusiwu ukhoza kusiyanitsa pafupifupi ndi mbali zinayi zotsatirazi.
(1) Chapamanja: Ulusi wofewa ndi silika, viscose ndi nayiloni.
(2) Kulemera kwake: Ulusi wa nayiloni, acrylic ndi polypropylene ndi wopepuka kuposa silika.Thonje, hemp, viscose ndi ulusi wolemera ndizolemera kuposa silika.Vinyoni, ubweya, viniga ndi ulusi wa polyester ndizofanana ndi kulemera kwa silika.
(3) Mphamvu: Ulusi wofooka ndi viscose, viniga ndi ubweya.Ulusi wamphamvu kwambiri ndi silika, thonje, hemp, ulusi wopangira, ndi zina zotere. Ulusi womwe mphamvu yake imachepa mukatha kunyowa ndi ulusi wa mapuloteni, ulusi wa viscose ndi ulusi wa copper-ammonia.
(4) Utali wotalikirapo: Potambasula ndi dzanja, thonje ndi hemp ndi ulusi wotalika pang’ono, pamene silika, viscose, ulusi wolemera ndi ulusi wambiri wopangidwa ndi ulusi wokhazikika.
(5) Kusiyanitsa ulusi wosiyanasiyana mwa kuzindikira ndi kumva.
Thonje ndi wofewa komanso wofewa, wonyezimira pang'ono komanso wosavuta kukwinya.
Zovala zimakhala zolimba komanso zolimba, nthawi zambiri zimakhala ndi zilema.
Silikayo ndi wonyezimira, wofewa komanso wopepuka, ndipo pamakhala phokoso laphokoso akautsina, lomwe limamveka bwino.
Ubweya umasinthasintha, wonyezimira wofewa, wofunda, wosavuta kukwinya.
Polyester ili ndi elasticity yabwino, yosalala, mphamvu yayikulu, kuuma komanso kumva kozizira.
Nayiloni ndiyosavuta kuthyoka, zotanuka, zosalala, zopepuka, osati zofewa ngati silika.
Vinylon amafanana ndi thonje.Kuwala kwake ndi mdima.Siyofewa komanso yolimba ngati thonje komanso makwinya mosavuta.
Ulusi wa Acrylic ndi wabwino poteteza, wamphamvu mu mphamvu, wopepuka kuposa thonje, ndipo umakhala wofewa komanso wofewa.
Viscose fiber ndi yofewa kuposa thonje.Kunyezimira kwawo kumakhala kolimba kuposa thonje, koma kufulumira kwake sikwabwino.
Sign Recognition Njira
Kuchepetsa kwa njira yomverera ndikuti ndi yokulirapo ndipo malo ogwiritsira ntchito siwotalikira.Zilibe mphamvu zopangira ulusi komanso nsalu zosakanikirana.Ngati ndi zovala zamkati zamtundu, mutha kumvetsetsa mwachindunji kapangidwe ka zovala zamkati kudzera pa signboard.Zizindikirozi zitha kupachikidwa poyang'anira bungwe loyang'anira nsalu ndipo ndizovomerezeka.Nthawi zambiri, palembapo pali zinthu ziwiri, imodzi ndi dzina la ulusi, ndipo inayo ndi ya ulusi womwe umawonetsedwa ngati peresenti.
