WATER PERMEABILITY IMPARTING AGENT AND FIBER HAVING THE AGENT APPLIED THERETO

摘要

A water permeability imparting agent comprising at least one specified quaternary ammonium salt and at least one specified phosphate salt in a specified ratio; and a water permeable fiber or fiber product comprising a fiber or fiber product having the agent applied thereto in an amount of 0.1 to 2.0 wt.%. Thus, the reduction of liquid return having relied on structural means, such as paper diaper and sanitary items, can be attained by the use of treating agent. Moreover, there are provided a water permeability imparting agent and a fiber or fiber product having the agent applied thereto, which realize enhancement of permanent water permeability, reduction of aging deterioration of permanent water permeability and capability with coping with speeding up of nonwoven fabric production process.
