I found information at kasbarnational.com - take a look. Got this from the website.
Since 1942, Kasbar National Industries, Inc. has been supplying quality textile products to commercial industry and the United States Government / Military.
Sounds like maybe they have a good product but not available to individuals. Looks like you might have found a real bargain if you can figure out the width and thickness of the batting. I'd hate to end up with 80 yards of something I couldn't use.
