PURPOSE: To obtain an absorptive substance having a high hydrophilicity and capable of not forming a rust during manufacturing thereof by arranging an absorbing material between a surface sheet consisting of a hydrophilic nonwoven fabric imparted with a specific alkylphosphate metal salt and a back sheet having the properties of not permeating liquid. CONSTITUTION: This hydrophilic nonwoven fabrics comprises imparting 0.05-2.0 pts.wt. alkylphosphate metal salt having an 8-12C alkyl group, >=30% branching ratio of alkyl group thereof, >=50% containing ratio of monoalkylphosphate metal salt and >=1 degree of neutralization, to 100 pts.wt. nonwoven fabrics consisting of composite fibers having a sheath core structure arranging a high melting resin such as a polyester to the sheath part and a polyolefinic resin to the core part. And an absorptive substance is obtained by using this hydrophilic nonwoven fabrics as a surface sheet and arranging an absorptive material between the fabrics and a back sheet having the properties of not permeating liquid. |
