M'zaka zaposachedwa, anthu ali ndi zofunikira zapamwamba komanso zapamwamba za chitonthozo ndi ntchito za nsalu za zovala. Chifukwa chakuchulukirachulukira kwa nthawi ya anthu pazochita zakunja, chizolowezi cholowa ndi kuphatikiza zovala wamba ndi zovala zamasewera zimakondedwanso ndi ogula ambiri. Nsalu za mtundu uwu wa zovala sizimangofuna chitonthozo chabwino, komanso zimafunanso kuti mukakhala achangu, mukakhala thukuta, zovala sizidzapaka khungu ndi kutulutsa kuzizira konyowa, kumverera kolemera. Choncho chofunika chatsopano cha kuyamwa kwa chinyezi ndi ntchito ya thukuta chimayikidwa patsogolo.
Komabe, chifukwa cha kuyamwa kwa chinyezi cha nsalu ndi thukuta, ogula ambiri adzasokonezeka. M'malo mwake, awa ndi malingaliro awiri, ndiwo mayamwidwe a chinyezi cha nsalu ndi kuchotsa chinyezi.
Choyamba, tiyeni tikambirane za mayamwidwe chinyezi: kupanga ulusi kutenga poliyesitala monga chitsanzo, kwenikweni, mayamwidwe madzi ndi yaing'ono, osauka permeability chinyezi, zosavuta kutulutsa kumverera kukakamira pamene yogwira; Ulusi wachilengedwe umatenga thonje mwachitsanzo, kuyamwa kwake kwa chinyezi kumakhala bwino komanso kumasuka kuvala, koma anthu akamatuluka thukuta pang'ono, ulusi wa thonje umakula chifukwa cha kuyamwa kwa chinyezi, ndikumamatira pakhungu, nthawi yomweyo, madzi. Divergence liwiro ndi pang'onopang'ono, motero kuchititsa ozizira chonyowa kumverera kwa thupi la munthu.
Chifukwa chake, pansalu zonse, makamaka zopangidwa ndi polyester, chithandizo ndi zowonjezera za hydrophilic pomaliza kumaliza ndi njira yabwino yopititsira patsogolo kuyamwa kwa chinyezi.
Koma kodi pamenepo ndiye mapeto ake? Kodi njira yothetsera chinyontho imachititsa kuti wovala aziuma? Hygroscopic = thukuta?
Inde sichoncho! Pokhapokha pamene chinyontho chomwe chimalowa mu nsaluyo chimatulutsidwa pamwamba pa nsaluyo momwe zingathere, chinyezicho chimasungunuka bwino pansi pa kuwala kwa dzuwa ndi mpweya wabwino, zomwe zimapangitsa kuti wovalayo akhale wowuma komanso womasuka.
Kuchotsa chinyezi cha nsalu makamaka kumadalira mawonekedwe a thupi la fiber. Chinyezi cha mpweya chomwe chimatuluka pamwamba pa khungu chimayamba kutengedwa ndi nsalu (ie hygroscopic,—- Dziwani kuti nsaluyo ndi hygroscopic, osati ulusi!). Ndiye capillary zotsatira kwaiye ndi mabowo (pores, micropores, grooves) mu CHIKWANGWANI ndi kusiyana pakati pa ulusi kumapangitsa chinyezi adsorption ndi kufalikira pakati pa nsalu. Mwa njira iyi, chinyezi chimasunthira pamwamba pa nsalu ndikutuluka nthunzi, motero kumaliza ntchito yochotsa chinyezi.
Choncho, kuyamwa chinyezi kokha sikukwanira. Kwa nsalu zina wamba zopangidwa ndi ulusi, pokhapokha atamaliza ndi zowonjezera za hydrophilic, kenako zotsatiridwa ngati "thukuta" la hygroscopic zidatibweretsa tonse ku kusamvetsetsana.
Popanga ulusi wopangira, malo enieni a ulusiwo amatha kusinthidwa mwakusintha mawonekedwe a mabowo a spinneret ndikupanga mikwingwirima yambiri munjira yotalikirapo ya ulusi. Izi zimathandizira kuti chinyontho chiziyenda bwino komanso kuti thukuta liziyenda bwino ndi mayamwidwe a ma groove awa. Mwachitsanzo, Invista imapanga chiphaso cha polyester cha COOLMAX® hygroscopic ndi satifiketi yopumira. Mtanda wake ndi wapadera lathyathyathya mtanda mawonekedwe, ndi CHIKWANGWANI pamwamba ndi kutalika mu grooves anayi. Malo ake enieni ndi aakulu 20% kuposa kuzungulira wamba, kotero kuti thukuta lake limagwira ntchito kuposa polyester wamba.
Chisamaliro chapadera chiyenera kuperekedwa kwa: Chifukwa cha kukonza, gawo la mtanda la nsalu mu chovalacho lawonongeka kwambiri (zomwe zimapangitsa kuti pulasitiki iwonongeke), kotero kuti kutuluka thukuta kumachepetsedwa kwambiri. Invista yatsopano ya polyester yamtundu wa "C, C, O, O" imatha kuchepetsa kupunduka kwa pulasitiki uku kwambiri, kuti kuchulukitse ntchito ya thukuta --C guide groove simapunduka mosavuta. Kuonjezera apo, kwa ogula, ntchito ya ulusi ndi yofunika, koma ubwino ndi ntchito ya nsalu ndizofunika kwambiri kuti zitsimikizire kuti chovalacho chimagwira ntchito.
