The structure of a hand duster having soft yarns retained on the end of a spirally wound metal wire is disclosed wherein the soft yarns are bunched together by means of a single loop at the end of the spirally wound metal wire. The yarns consist of crimped synthetic fibers in two state permanently secured at their intermediate region by the single loop of the twisted wire. The method comprises preparing a bunch of yarns and retaining same against the curved end of the bent wire shaped in a hairpin configuration, and retaining the curved end of the wire while the generally parallel extending legs are spirally wound around one another along a straight line resulting in a tightly gripping loop around the middle portion of the bundle of yarns. The yarns are then teased and trimmed thereby to produce a round fluffy head portion. The spirally wound stem is then cut to a predetermined length and then a handle component is permanently secured to the free end of the stem.
A hand duster for use primarily for dusting furniture, decorative articles and the like comprising a relatively large fluffy head of generally spherical configuration, a handle, and wire means retaining said head to one end of said handle, said head consisting of a very large number of fine, flexible elements extending essentially radially from a central region located in the center of said head, said elements being defined by a bundle of coextensively juxtaposed fibers which are retained together in their middle region by means of a single loop defined by said wire means at one end thereof and located in said central region, said wire means having two leg portions intertwisted along a common longitudinal axis thus defining a twisted wire stem, said stem projecting into an axial bore in said one end of said handle and being secured thereto, said bundle of fibers consisting of a bunch of crimped synthetic fibers in tow state measuring about six inches long and which form said generally spherical configuration, the structure of the fibers which provides said generally spherical configuration being a teased state resulting from teasing of the fibers of the bundle in tow state once secured to said wire means.
A hand duster for use primarily for dusting furniture, decorative articles and the like, comprising a relatively large fluffy generally spherical head portion, a handle, and a twisted wire retaining said head portion to said handle, said head portion being made of crimped acrylic fibers in tow state such as used as starting material in the textile industry, each fiber being about six inches long, said fibers being bunched together in the middle by said twisted wire, said twisted wire defining a loop at one end thereof which encircles said bunch of fibers in the middle, said twisted wire defining a twisted wire stem at the end opposite said loop, said stem being secured to the adjacent end portion of said handle, said bunched fibers being teased to provide said generally spherical head portion, and each fiber defining on either side of said loop a radially extending soft and flexible element.
