Izembozo zebhuthi ezincane ezihlanganiswe ngendwangu ethambile ye-polypropylen engalukiwe nefilimu encane, ivumela umhwamuko ukuba uphume ukuze ugcine umuntu owugqokile ekhululekile. Kuyisithiyo esihle sezinhlayiya ezimanzi noma eziwuketshezi nezomile. Ivikela uketshezi olungenabuthi oluyi-spary, ukungcola nothuli.
Amakhava ebhuthi amancane ahlinzeka ngokuvikeleka kwezicathulo okukhethekile ezindaweni ezibucayi kakhulu, okuhlanganisa izinqubo zezokwelapha, izimboni zemithi, amagumbi ahlanzekile, imisebenzi yokuphatha uketshezi olungenabuthi kanye nezindawo zokusebenza ezivamile zezimboni.
Ngaphezu kokuhlinzeka ngokuvikeleka okuyindilinga, izembozo ze-microporous zikhululekile ngokwanele ukuba zigqoke amahora amaningi okusebenza.
Iba nezinhlobo ezimbili: Iqakala elinwebekayo noma iqakala elibophayo
