Nsalu yosalukidwa imeneyi imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga kulongedza, zida zosefera, ndi chisamaliro chaumoyo.

Nsalu ya polypropylene spunbond nonwoven: Nsalu ya polypropylene spunbond imapangidwa makamaka kuchokera ku ulusi wa polypropylene. Ulusi wa polypropylene umapangidwa ndi polymer kuchokera ku propylene, wopangidwa kuchokera ku petroleum kuyenga, ndipo amatha kupuma bwino, kusefa, kutsekereza, komanso kuteteza madzi. Kapangidwe ka nsalu za polypropylene spunbond nonwoven n'zofanana ndi nsalu za polyester spunbond nonwoven, zomwenso zimapangidwa ndi ulusi kudzera muukadaulo wa spunbond. Chifukwa cha zinthu zabwino kwambiri za ulusi wa polypropylene, nsalu za polypropylene spunbond nonwoven zimakhala ndi ntchito zambiri pakuyika, ulimi, zomangamanga ndi zina.

Kuphatikiza apo, nsalu zopanda spunbond zimathanso kugawidwa kutengera zinthu zina, monga makulidwe a ulusi, makulidwe a nsalu zosawomba, kachulukidwe, komanso kagwiritsidwe ntchito. Mitundu yosiyanasiyana iyi ya nsalu za spunbond nonwoven ili ndi mtengo wapadera wogwiritsa ntchito m'magawo awo.
