Porous sheet |
摘要 |
A porous sheet is disclosed that comprises a thin, flexible sheet made of thermoplastic resin having solid particles distributed therein. Small spaces are formed around the particles, such that abrasion or buffing of the opposite surfaces of the sheet causes the formation of a multitude of fine pores that extend through the sheet, making the sheet vapor-permeable but liquid-impermeable.
