Standing duster article
US-7788759-B2Abstract
A standing duster article consisting of a dusting portion and a spiral handle, wherein the dusting portion is comprised of a segmented intermingled yarn layer, a hot-meltable nonwoven fabric layer, a smooth nonwoven fabric layer, and a nonwoven/woven fabric layer; the segmented intermingled yarn layer is interleaved between the hot-meltable nonwoven fabric layer and the smooth nonwoven fabric layer; the nonwoven/woven fabric layer is further superimposed on the smooth nonwoven fabric layer; a hot-pressing process is carried out to fuse the segmented intermingled yarn layer, the hot-meltable nonwoven fabric layer, the smooth nonwoven fabric layer, and the nonwoven/woven fabric layer; the resulted lamination after fusion is cut by a cutting apparatus, so as to generate a slit in the middle to form the dusting portion which is easy to be folded to form two elongated openings; and a spiral end of the spiral handle is inserted into the openings to form the duster article with the spiral dusting portion. Since the intermingled yarn of the segmented intermingled yarn layer used in the present invention comprises alternate loose and tight segments, the fibers on the loose segments of the intermingled yarn are capable of capturing more dust powder. The alternate loose and tight segments are formed by twisting the intermingled yarn, such that each of the bundles of the intermingled yarn is effectively bound and will not tangle with each other. Further, it is easy to install or remove the spiral handle in or from the dusting portion by such design.
