Pamene zinyalala za pulasitiki za m’nyanja zisintha kuchoka ku zolemetsa za chilengedwe n’kukhala pachimake cha luso lazopanga nsalu, ndiye mfundo yaikulu ya ulusi wobwezerezedwanso m’madzi. Imaganiziranso maukonde ophera nsomba otayidwa, mabotolo apulasitiki, ndi zinyalala za m'nyanja kudzera m'chimake chozungulira, kulumikiza kukonzanso kuwononga chilengedwe ndi sayansi yokhazikika. Meta iliyonse ya ulusi imakhala ndi zolinga ziwiri: kuyankha pakuwonongeka kwa m'madzi komanso kuwunika kwa nsalu zomwe zimakhudzidwa ndi chilengedwe, kulola kuti nsalu zizitchinjiriza ku zinthu zomwe zikugwirizana ndi kudzipereka kwa anthu pakubwezeretsanso nyanja.

Ulusi wamphamvu kwambiri wa Nylon (PA6) umadziwika chifukwa cha kulimba kwake kwamphamvu komanso kutalika kocheperako, kukhazikika komanso mawonekedwe akuthupi amakwaniritsa miyezo yamakampani - kutchuka kwambiri kuyambira pomwe msika udayamba. Motsogozedwa ndi kukana kwabwino kwambiri kwa ma abrasion, imapambana mu ntchito za ulusi ndi zingwe: kuchokera ku ulusi wa Banda, zingwe zolemera kwambiri kupita ku ulusi wosoka wothamanga kwambiri, komanso kuchokera ku zingwe zopha nsomba zam'madzi kupita ku zingwe zapadera zankhondo, imapirira mikangano yamphamvu kwambiri. Pakuluka, imapanga nsalu za nayiloni zamphamvu kwambiri ndi zida zoyambira za lamba wa chinjoka, zopangira ma sailcloth, nsalu zosefera zamphamvu kwambiri, ndi zinthu zina zokhazikika.

Light-Shielding Polyester Ulusi umatanthauziranso nsalu zogwira ntchito mwa kuphatikiza yunifolomu ya tinthu tating'onoting'ono totchinga ndi nano mu unyolo wa ma molekyulu a polyester kudzera muukadaulo wophatikizika wopota. Kapangidwe kake ka "photonic shielding matrix" kumapangitsa kuti kuwala kuwoneke kangapo ndi kuyamwa mkati mwa ulusi, kukwaniritsa ≥90% kuyanika kowoneka bwino popanda zokutira zachiwiri. Kuchokera pa makatani akuda ku hotelo mpaka nsalu zotchinga ndi dzuwa zamagalimoto, kamangidwe kameneka kamene kamakhala ndi mphamvu ya kuwala kwapamalo, kumasintha chingwe chilichonse kukhala chotchinga chosaoneka kuti chisawalire kwambiri. Mwa kulinganiza kusapezeka kwa kuwala ndi kupuma kwa nsalu, kumakhazikitsa mulingo watsopano wa zokometsera zogwira ntchito pakugwiritsa ntchito shading.

Ulusi wa infrared ndi nsalu yogwira ntchito yopangidwa ndikuyika tinthu tating'onoting'ono ta ceramic mu ulusi. Mukakumana ndi thupi la munthu, tinthu tating'onoting'ono ta ulusi timatenga kutentha kwa chilengedwe ndipo timatulutsa kuwala kwakutali kwakutali kwa 8-14μm, kutulutsa mphamvu yama cell amunthu kuti ipititse patsogolo kufalikira kwa magazi ndikuwonjezera kutentha kwamafuta. Zovala zopangidwa kuchokera ku ulusi umenewu sizimangotentha komanso zimakhala ndi mpweya wabwino komanso zotonthoza, zoyenera kupanga zovala zamkati zotentha, zovala zamasewera, ndi zachipatala.

Ulusi wa infrared ndi mtundu wa ulusi wogwira ntchito. Panthawi yozungulira, ma ufa okhala ndi ma infrared amawonjezedwa. Mafutawa amaphatikizapo zitsulo zina zogwira ntchito kapena zopanda zitsulo, monga aluminium oxide, zirconium oxide, magnesium oxide, ndi biomass carbon, etc. Pambuyo pophwanyidwa mpaka nano kapena micro-nano powder level, amadziwika kuti ndi ufa wochuluka wa ceramic. Akasakanizidwa mofanana, amakokedwa kukhala ulusi. Ulusi uwu ndi zinthu zake zimakhala ndi zida zabwino zotchinjiriza ndipo zimagwira ntchito pazachipatala m'moyo watsiku ndi tsiku.

M'nyengo yamvula, kodi munayamba mwalakalakapo nsalu imene imachititsa khungu lanu kukhala lozizirira bwino? Pamene zovala zothira thukuta sizikuvutitsaninso ndipo kusungunuka kumatayika nthawi yomweyo, ulusi wozizira bwino ndi nsalu zimasinthanso kuvala zochitika ndi luso lamakono - kuchokera ku chinsinsi cha chinyezi cha zigawo zozungulira mpaka ku nzeru zowononga kutentha kwa mchere wa mchere, ndikufufuza momwe zinthu zoziziritsira "zopumira" zikubweretsa kusintha kwa nyengo yachilimwe.
