PROBLEM TO BE SOLVED: To obtain a binder improving a solvent resistant strength which be come a problem in producing a low weight non-woven fabric, and used for producing a non-woven fabric excellent in electrical insulating property, and such non-woven fabric. SOLUTION: This binder is characterized by adding 10-150 pt.wt. (total weight of solid portion) dibasic acid ester with 100 pts.wt. thermosetting resin emulsion. In this case the binder is contained by 5-30 wt.% based on the weight of the electrically insulating non-woven fabric.
