Abstract
Tobacco smoke filter rods made with fibers selected from cellulose acetate, poly(ethylene terephthalate) and poly(hexamethylene adipamide) bonded with water and glycol bonding dispersions 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.
