Comparison Between Acrylic Latex and Ultrasonic Bonding of a Polyolefin Nonwoven, 1992 Nonwovens Conference Proceedings

Performance properties of a polyolefin nonwoven subjected to low (68.90 kPa, 5.49 m/-min), medium (103.35 kPa, 9.15 m/min), and high (172.25 kPa, 9.15 m/min) degrees of ultrasonic bonding and to a 5(5) X 3 X 2(2) customized

fractional factorial experimental design (-CFFED) (listed in Table 1) which consisted of foam, pad, and spray application of 1, 2.5, 5, 10, and 20 % straight chain acrylic latex binder (based on the acrylic latex solids in the bath) formulations were compared. Latex bonding reduced fiber transference as measured by the peel test (ASTM D 3330-87) to a greater degree than ultrasonic bonding. Ultrasonic bonding produced samples that were as soft as yet stronger than the untreated material. Air permeability was reduced by both latex and ultrasonic bonding, but to a greater degree by ultrasonic bonding.
