Embodiment 1

[0036] The fibrous filler of Example 1 was an extremely lofty nonwoven web produced by a vertically lapped nonwoven process. The staple fibers used were recycled polyester (PET) fibers, with bicomponent fibers being used as the binder component.

[0037] To achieve wrapping, remove from SCOTCH-BRITE by tearing one end seam TM Dobie Scrub Pad removes netted polypropylene mesh. The vertically lapped nonwoven web was then cut into lengths of 3.7 inches to 4.3 inches and widths of 2.5 inches to 3.0 inches using scissors and inserted by hand into the polypropylene mesh and the end seams re-sewn.

Embodiment 2 to Embodiment 5

[0039] The fibrous fillers of Examples 2 through 5 were obtained using a conventional airlaid web forming machine (commercially available under the trade designation "RANDO-WEBBER" from Rando Machine Corporation, Macedon, New York). Produces extremely lofty and elastic nonwoven webs. If different staple fibers are used, the staple fibers are blended by weight percent. The thickness of the nonwoven web is in the range of 15 mm to 30.0 mm, and the areal weight (basis weight) of the web is in the range of 100 grams per square meter (gsm) to 400 grams per square meter. The nonwoven web was then passed through a ventilated oven at a temperature in the range of 100°C to 250°C, resulting in a pre-bonded, lofty nonwoven web.

[0040] To achieve wrapping, remove from SCOTCH-BRITE by tearing one end seam TM Dobie Scrub Pad removes netted polypropylene mesh. The nonwoven web was then cut using scissors into a length of 3.7 inches to 4.3 inches and a width of 2.5 inches to 3.0 inches, ...

Abstract

The present invention is a cleaning article including a filler and a wrapping at least partially surrounding the filler. At least one of the filler and the wrapping are composed of a sustainable material.

Description

technical field [0001] The present invention relates generally to the field of cleaning articles. Specifically, the present invention is a sustainable scrubbing pad. Background technique [0002] Scrubbing pads are widely used for cleaning surfaces, such as household surfaces (including surfaces in the home) and vehicle surfaces. Scrubbing pads are typically used with water and soap or detergent, where the scrubbing surface of the scrubbing pad is used to clean the surface. Such surfaces include dishes, utensils, glasses, jars, pans, grills, walls, floors, countertops and vehicle surfaces, as well as windows. [0003] Scrubbing materials can be made in many forms, including nonwoven webs (eg, the low density nonwoven abrasive webs described in US Patent No. 2,958,593). According to its manufacturing process, the web of scouring material can be cut into individual pieces of suitable size for hand use (for example, a single rectangular pad as described in U.S. Patent No. 2,...
