Abstract
A nonwoven disposable article is constructed using adhesive compositions containing 1 to 25% of a surfactant, which causes the adhesive composition to exhibit a contact angle of 90.degree. or less and a reduction in surface tension of less than or equal to about 35-40 dynes/cm, giving improved wicking capabilities to the nonwoven.
Claims5
A disposable article containing an absorbent core bound together or reinforced with hot melt adhesive fibers consisting of (a) 10 to 80 weight percent of an olefin containing polymer, (b) 10 to 70 weight percent of a compatible tackifying resin, c) 0 to 20% plasticizer, (d) 0 to 2% stabilizer, (e) 0 to 25% wax, and (f) 1 to 25% of a surfactant, which surfactant will cause the adhesive composition to exhibit a contact angle of 90.degree. or less and a reduction in surface tension of less than about 40 dynes/cm.
