ABSTRACT:
A process for solvent bonding blended nonwoven fabrics is disclosed. The fabric is obtained by forming a web from a blend of fibers selected from the group consisting of acrylic fibers, modacrylic fibers and mixtures thereof and polyester fibers, applying a controlled amount of solvent to the web, and then bonding contiguous fibers at their cross-over points by the application of heat and pressure so as to activate the solvent. The fabric thereby obtained is characterized by improved elongation and tear strength.
