Abstract
The present invention provides a nonwoven composite and a process for making a nonwoven composite suitable for making shoe counters comprising: (1) dispersing an effective amount of a thermoplastic resin throughout the interstitial space of a nonwoven fabric having two fabric surfaces wherein the first fabric surface has a velvety or felt texture and the second fabric surface has a fused surface thereby forming a thermoplastic resin-loaded nonwoven fabric; thereafter heating said thermoplastic resin-loaded fabric in a manner which impregnates said thermoplastic resin onto the nonwoven fabric thus forming said nonwoven composite with one velvety or felt surface substantially free of thermoplastic resin in the absence of buffing.
