Zomwe zimatchedwa zofewa komanso zomasuka za nsalu ndikumverera kokhazikika komwe kumapezeka mwa kukhudza nsalu ndi zala zanu.Anthu akamakhudza nsaluzo, zala zawo zimatsetsereka ndikuzipaka pakati pa ulusi, kumverera kwa dzanja la nsalu ndi kufewa kumakhala ndi ubale wina ndi mphamvu ya kugunda kwamphamvu kwa ulusi.Kuphatikiza apo, fluffiness, plumpness ndi elasticity zipangitsanso dzanja kumverera kwa nsalu yofewa.Zikuwonetsa kutikumverera kwadzanjazimagwirizana ndi kapangidwe kapamwamba ka ulusi.Tengani zofewa za surfactant mwachitsanzo.Mfundo yogwiritsira ntchito zofewa nthawi zambiri imaganiziridwa kuti imafotokozedwa m'njira ziwiri.Ndizosavuta kuti ma surfactants azikhala ndi ma adsorption ozungulira pamwamba pa ulusi.Ngakhale kuti ma surfactants amatsatiridwa pamalo olimba omwe amachepetsa kupsinjika kwapamtunda, gawo la fiber ndizovuta kukulitsa.Ndipo ulusi nsalu amapangidwa ndi liniya macromolecule ndi lalikulu kwambiri enieni padziko ndi mawonekedwe elongated, amene unyolo maselo ali kusinthasintha wabwino.Pambuyo poyamwa ma surfactants, kuthamanga kwapamtunda kumachepa, zomwe zimapangitsa kuti ulusiwo ukhale wosavuta kukulitsa komanso kutalika kwake.Kotero kuti nsaluzo zimakhala fluffy, zonenepa, zotanuka komanso zofewa.Kuchuluka kwa ma adsorptant a surfactant pamwamba pa ulusi komanso kuchepetsa kupanikizika kwa ulusi, zotsatira zofewa zimawonekera kwambiri.cationic surfactants akhoza mwamphamvu adsorbed pa CHIKWANGWANI pamwamba ndi electrostatic mphamvu (Ulusi wambiri amakhala ndi zoipa pamwamba mlandu).Pamene gulu la cationic likuyang'anizana ndi ulusi ndipo gulu la hydrophobic likuyang'anizana ndi mpweya, zotsatira za kuchepa kwa minyewa yam'mlengalenga zimakhala zazikulu.
Mayamwidwe okhazikika a surfactants pamtunda wa ulusi amapanga filimu yopyapyala yamagulu a hydrophobic yokonzedwa bwino kunja, zomwe zimapangitsa kuti mkangano pakati pa ulusi uchitike pakati pa magulu a hydrophobic omwe amasenderana.Chifukwa chamafuta amagulu a hydrophobic, kugundana kwapakati kumachepetsedwa kwambiri.Ndipo gulu la unyolo la hydrophobic ndi lalitali, limatsetsereka mosavuta.Kuchepa kwa friction coefficient kumachepetsanso flexural modulus ndi kukanikiza kwa nsalu, zomwe zimakhudzachogwirira.Panthawi imodzimodziyo, kuchepa kwa friction coefficient kumapangitsa kuti ulusi usungunuke mosavuta pamene nsaluyo imakhudzidwa ndi mphamvu zakunja, kotero kuti kupanikizika kumabalalitsidwa ndipo mphamvu yong'ambika imakhala bwino.Kapena panthawi yogwira ntchito, ulusi womwe umagwiritsidwa ntchito mwamphamvu umakonda kubwerera ku malo omasuka mosavuta, kupangitsa chogwiriracho kukhala chofewa.Anthu akakhudza ulusi, static friction coefficient imathandizira kwambiri pakufewa kwa nsalu.Koma kunena kwake, kumverera kofewa kwa dzanja la ulusi kumakhudzana kwambiri ndi kuchepetsedwa kwa static friction coefficient.
Kufewetsa kumalizitsa nthawi zambiri kumatanthawuza pawiri yomwe imatha kutsatiridwa pa ulusi ndikusalala pamwamba pa ulusi, ndikuwonjezera kufewa kwa ulusi.Pakalipano, pali mitundu iwiri yomwe imagwiritsidwa ntchito kwambiriwofewetsa, monga surfactants ndi mkulu-maselo softening agents.Zofewa za mamolekyulu apamwamba kwambiri zimaphatikizapo zofewa za silicone ndi ma emulsion a polyethylene.
