A FILL OR EFFECT MATERIAL ABSTRACT A method of manufacturing a fill or effect material, the method including feeding a synthetic or natural fibrous material to a woollen opening mechanism with its outlet closed, running the opening mechanism for a predetermined period, opening the outlet from the opening mechanism so that the rotating opening mechanism throws therefrom a plurality of modified neps, each of which has a nep shaped region from which extends a tail of fibres which modified neps are hereinafter referred to as long tailed neps. The fibrous material can be scoured wool, a synthetic fibrous material or woollen fibres in an unclean state with vegetable matter and other contaminants entrained therewith. In addition there is provided a mechanism for manufacturing a fill or effect material, the mechanism including a means for feeding a synthetic or natural fibrous material to a housing having a closable inlet and a closable outlet, the housing forming a chamber in which a rotating member is mounted, the rotating member having on its periphery a plurality of teeth which co-operate with teeth on the inner periphery of the chamber, the arrangement being such that material fed through the inlet and allowed to spin in the closed chamber for a predetermined period is formed by the interaction of the teeth into a plurality of modified neps each of which has a nep shaped region from which extends a tail of fibres which modified neps are hereinafter referred to as long tailed neps. The housing preferably includes a fan doffer type roller alongside the rotating member, the doffer type roller rotating at a higher speed than the rotating member and being adapted to beat from the teeth on the rotating member the partly processed material and feed same toward the outlet.
