PURPOSE:To provide the subject treating agent capable of improving the curd- passing ability of binder fibers and also imparting sufficient water repellency to the prepared non-woven fabric by containing a specific alkyl phosphate, an emulsifier, a higher alcohol, dimethylsilicone, etc., in specified amounts, respectively. CONSTITUTION:A water-repellent treating agent imparting both electrostaticity and water repellency and used for binder fibers contains 20-45wt.% of a 14C alkyl phosphate, 20-70wt.% of a carboxy-modified polyethylene wax having a mol.wt. of 1000-10000, an acid value of 5-50 and containing 5-30wt.% of an emulsifier, 5-10wt.% of a higher alcohol and 2-5wt.% of dimethylsilicone or a modified product thereof. The polyethylene wax is preferably preliminarily emulsified into an O/W type emulsion and subsequently compounded with the treating agent. The employment of the treating agent permits to impart both an electrostatic action and a water-repellent action to the binder fibers, thereby permitting to use the non-woven fabric prepared from the binder fibers for diapers or sanitary napkins without again requiring any water-repellent treatment and to give a good non-tacky touch of use when worn.
