A fiberfill blend for making into a batt for heat-bonding, consisting essentially of three ingredients: (a) two of the ingredients are crimped polyester staple fiber; (1) one of these polyester fiberfill ingredients is slickened with a durable coating; (2) the other of these polyester fiberfill ingredients is unslickened; each of ingredients (1) and (2) constitutes 25 to 75% of the polyester fiberfill (a); (b) the third ingredient is crimped binder fiber of a polymer having a melting point lower than that of the (a) ingredients; the binder fiber is present in amount 10 to 30% of the blend; the remaining 70 to 90% of the blend is the polyester fiberfill. Such blends can be processed on conventional textile machinery, e.g., by carding and cross-lapping, and heated to activate the binder fibers and make a stable heat-bonded batt. Preferred batts, using polyester staple fibers of regular denier, have surprisingly high resilience, which makes them especially suitable for use in pillows and cushions. |
