Zusammenfassung:Cigaret filters readily broken down by H2O contained as binders mixts. of high boiling polyols, 5-40 wt.% H2O-dispersible polyester, polyamide, or polyester-polyamide which was sol. in polyol. Thus, a stand of 39,600 3.3 denier cellulose acetate fiber having 4.73 crimps/cm was sprayed with a mixt. of propyleneglycol 70, H2O 5, and 10:9:1 diethylene glycol-isophthalic acid-sodiumsulfoisophthalic acid polymer(I), and then molded into filters.
