Abstract: A polyester filament in which a polyether-polyester block copolymer 18 dispersed ?s fine striae, at least one of which striae is substantially endless along the filament axis. Process for preparing the same includes a melt spinning apparatus with static mixing elements interposed between separate molten polymer feed passageways and spinneret holes. These filaments exhibit improved antistatic properties.

Abstract: A thermal-insulating nonwoven bulky product characterized in that it is structurally made up of substantially continuous single filaments of between about 0.01 to 2 deniers stabilized in the product by a surface binder on the filaments, said filaments being continuous filaments randomly crimped as individual filaments, a multiplicity of said filaments being individually crimped and free of agglomeration with other filaments. This fibrous non-woven product is useful as a thermally insulating stuffing and packing material and compares favourably with down.
