ABSTRACT:
Blends of 55 to 97% by weight crimped hollow polyester fiber having a void content of from 8 to 30% by volume and 3 to 45% by weight of crimped lower-melting polyester binder fiber impart advantageous properties to bonded low density batts made therefrom, such as high filling power but low load bulk which makes the batt particularly useful as fiberfill for garments.
