Abstract: The disclosed cleaning article includes a working surface made from first ends of a plurality of channels and a capturing surface. The channels are formed from multiple strands of a skip-slit sheet, which in an initial state extend in a first direction and together define a plane. The multiple strands are attached to each other at bridging regions. At least some of the strands are spread from the initial state and separated from each other between the bridging regions to provide the plurality of channels, and at least some of the strands that are separated from each other are twisted out of the plane. A cleaning tool including the cleaning article, a method of making the cleaning tool, and a stack of skip-slit spunbond nonwoven sheets are also disclosed.

Abstract: A blend of polyester staple fibers and insulation fill materials useful as a replacement for natural down in articles such as outdoor apparel, sleeping bags, bedding, etc. The blend includes first, second and optionally third polyester staple fiber formats that differing in terms of average diameter. A length of substantially all the fibers of the blend is in the range of about 16 to about 63 mm, alternatively 20-40 mm. At least a majority of the fibers of the blend are opened. In some embodiments, some or substantially all of the fibers of the blend are crimped and/or include a lubricant (e.g., siliconized). One non-limiting example blend includes 20-30 weight percent of not greater than 1 Denier fibers, 20-30 weight percent of greater than 1 up to 2 Denier fibers, and 40-60 weight percent of greater than 2 Denier fibers.
