Provided is a nonwoven fabric substrate (1) in which ridges (2) and grooves (3) are alternately formed at positions corresponding to each other on each of both surfaces (1a, 1b), and apertures (4) penetrating the grooves (3) of both surfaces are formed. The ridges (2) and the grooves (3) extend parallel to each other. The ridges (2) and the grooves (3) extend in a direction intersecting with each of a pair of both sides (1c, 1d) extending in parallel of the nonwoven fabric substrate (1). In planar view, each of the grooves (3) alternately includes an aperture portion (3h) which has a plurality of the apertures (4), and a non-aperture portion which has no aperture (4) and is longer than a distance between the nearest end portions of the adjacent apertures (4) in the aperture portion (3h), and arrangement patterns of the aperture portion (3h) and the non-aperture portion (3n) provided in the adjacent grooves (3) are different from each other. When the nonwoven fabric substrate (1) is seen in planar view, the nonwoven fabric substrate (1) has an aperture region (11) formed by the aperture portion (3h) of the plurality of grooves (3), and a non-aperture region (12) formed by the non-aperture portion (3n), and the aperture region (11) and the non-aperture region (12) are arranged in a predetermined pattern.

A disposable cleaning pad having a grout cleaning brush includes a bristle attachment for use with a disposable pad. The bristle attachment is molded into a rectangular base piece forming a stand-alone removable brush that can be removably attached to a disposable pad. A top rectangular piece of similar dimensions to the base is connected to the end portion of the base by way of a hinge. The ends opposite the hinge have mating clasps that allow for the brush assembly to be securely yet removably fastened to an existing cleaning pad which is then mounted in the normal manner to the cleaning system. The brush assembly enjoys a longer life than that expected from a disposable cleaning pad thus the brush assembly may be reused many times before it needs to be replaced.

The present invention relates to articles for cleaning hard surfaces and in particular to remove large particles and hairs from large surfaces. The articles comprise an adhesive having specific Theological properties that provide increased efficacy in capturing and trapping large particles and hairs.

A resilient cleaning pad with a support body a portion of which is mechanically secured in a slit-like cavity of the cleaning pad.

A method and system for the production of fibers for use in biocomposites is provided that includes the ability to use both retted and unretted straw, that keeps the molecular structure of the fibers intact by subjecting the fibers to minimal stress, that maximizes the fiber's aspect ratio, that maximizes the strength of the fibers, and that minimizes time and energy inputs, along with maintaining the fibers in good condition for bonding to the polymer(s) used with the fibers to form the biocomposite material. This consequently increases the functionality of the biocomposites produced (i.e. reinforcement, sound absorption, light weight, heat capacity, etc.), increasing their marketability. Additionally, as the disclosed method does not damage the fibers, oilseed flax straw, as well as all types of fibrous materials (i.e. fiber flax, banana, jute, industrial hemp, sisal, coir) etc., can be processed in bio composite materials.

Embodiments herein are related to hydrophilic open cell foams with particulate fillers. In an embodiment, an article is provided that has an open cell foam structure including a hydrophilic polymer and about 0.1 wt. % to about 40.0 wt. % of a particulate filler dispersed within the hydrophilic polymer. The open cell foam structure can exhibit a rate of absorption of water greater than an otherwise identical foam lacking the particulate filler. Other embodiments are included herein.
