PURPOSE:To obtain a nonwoven sheet having excellent antistatic properties without impairing waterproofness by applying a specific phosphate salt compound to a polyolefin nonwoven sheet. CONSTITUTION:A polyolefinic polymer is formed into a three-dimensional netlike fiber by, e.g. a flash spinning method and the resultant nonwoven polyolefin sheet is presubjected to corona discharge treatment. A textile treating agent expressed by the formula (M is lithium, sodium potassium, H or ammonium; m and n are 1 or 2), e.g. a blend of a monomethoxy lower alkyl phosphate salt with a bismethoxy lower alkyl phosphate salt at 1:1 molar ratio in an amount of >=0.01wt.% owf is applied to the resultant nonwoven polyolefin sheet to afford the objective nonwoven polyolefin sheet, having waterproofness and simultaneously excellent in antistatic properties. |
