Abstract
A fibrefill blend comprising, and a bonded batt formed from, (a) from 90 to 50% by weight of slickened crimped hollow polyester fibre having a cavity volume of 10 to 30% and, complementally, to total 100% conjugate fibre, the hollow polyester fibres and the conjugate binding fibres having substantially the same density and decitex (and so diameter).
Claims2
A fibrefill blend comprising (a) from 90 to 50% by weight of slickened crimped hollow polyester fibre having a cavity volume of 10 to 30% and, complementally, to total 100% by weight, (b) from 10 to 50% by weight of slickened crimped conjugate fibre, the improvement being that the hollow polyester fibres and the conjugate binding fibres have substantially the same density and decitex (and so diameter) and that the conjugate fibre comprises a polyester core and a polyolefin sheath.
