Abstract
Acrylic latex polymers which are widely used as backcoatings for fabrics dielectrically heat sealed in automotive interior trim constructions can cause arcing on nylon-containing fabrics during heat sealing. Arcing causes fabric charring. Most nylon fabrics, because of their polar and hydroscopic nature, are prone to arcing. A latex backcoating can aggravage this problem further. This talk discusses several new acrylic latexes developed for arc resistant backcoatings for nylon fabric, presenting comparative dielec tric heat sealing data on several nylon-containing fabrics. The role of the nonwoven plumper pad adhesive (usually a preplasticized PVC latex) used in the interior trim construc tions is also discussed.
