ABSTRACT:
A fiberfill blend for making into a batt for heat-bonding of said batt to make it especially suitable for use in garments, consisting essentially of three ingredients: (a) two of the ingredients are crimped polyester staple fiber of lower denier than has commonly been used heretofore in polyester fiberfill, namely less than about 3 denier; (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 low denier polyester fiberfill. Such blends can be processed on conventional textile machinery to a stable thin batt, preferably by carding, needle-punching, and heating to activate the binder fibers, and these stable thin batts have high thermal insulation properties combined with attractive aesthetic properties that make them suitable for use in garments.
