ABSTRACT:
Water and glycol bonding dispersion comprising water, high boiling glycols selected from 1,2-propanediol, 1,3-propanediol, 1,4-butanediol, 1,2-butanediol and 1,3-butanediol; and water and glycol dispersible polyester polymers. The polymer is present in the amount of about 5 to 40% by weight of the dispersion and preferably about 15 to 35% by weight, and is selected from polyesters of combinations of isophthalic acid and the sodium, potassium, or lithium salt of sulfoisophthalic acid reacted with diethylene glycol or triethylene glycol; and from terephthalic acid and the sodium, potassium or lithium salt of sulfoisophthalic acid reacted with diethylene glycol or triethylene glycol. The water and selected glycol(s) serve as a carrier or dispersion medium for the selected water and glycol dispersible polymer. The dispersions contain from about 0.1-20% water by weight. Also disclosed are tobacco smoke filter rods of cellulose acetate fibers, poly(hexamethylene adipamide) fibers and of poly(ethylene terephthalate) fibers bonded with the bonding dispersion.
