Disposable thongs, panties, and briefs are generally made of soft, breathable, non-woven fabric like SMS (spunbond/meltblown/spunbond) polypropylene and sometimes have a thin cotton lining. Besides disposable underwear, this fabric is widely used for face masks, exam gowns, beddings, caps, and other medical healthcare and sanitary products. The reason meltblown and spunbond PP are combined in these garments is to provide both water-resistance and comfort. The fact that they are very lightweight and skin-friendly also contributes to comfort.
