Toilet paper 卫生纸
(重定向自Lavatory paper)
Toilet paper is a tissue paper product primarily used for wiping and cleaning the anus and surrounding area of fecal material after defecation and by human females for cleaning the perineal area of urine after urination and other bodily fluid releases. It also acts as a layer of protection for the hands during these processes. It is sold as a long strip of perforated paper wrapped around a paperboard core for storage in a dispenser by a toilet. Most modern toilet paper in the developed world is designed to decompose in septic tanks, whereas some other bathroom and facial tissues are not. Toilet paper comes in one-ply all the way up to six-ply, meaning that it is either a single sheet or multiple sheets placed back-to-back to make it thicker, softer, stronger and more absorbent.
