Nsalu zokhala ndi spunlace zosalukidwa zoyenera nsalu za electrostatic adsorption nthawi zambiri zimapangidwa ndi kuphatikiza kwa polyester (PET) ndi zomatira, zolemera pafupifupi 45-60g/㎡. Kulemera uku ndi zinthu zimatha kulinganiza mphamvu ya electrostatic adsorption, kusinthasintha, ndi kuyeretsa kunyamula, kuwonetsetsa kuyeretsa komanso moyo wantchito wa nsalu.
