ABSTRACT OF THE DISCLOSURE A non-woven textile fabric having good pliability and durability is produced by calendering a fiber assembly, partially applying a bonding agent to the fiber web, drying the bonding agent, and applying heat and pressure to force the bonding agent into the fiber web and to densify the web in areas where the bonding agent is present. The heat and pressure step does not effect polymerization and crosslinking hardening of the bonding agent, but does allow the portions of the web having no bonding agent to expand to high bulkiness. Subsequently the web is subjected a heat treatment step in which crosslinking and polymerization of the bonding agent occurs.
