Cross layer fiber entanglement to increase strength of 3D part
A printed sheet fiber entanglement apparatus entangles fibers from neighboring printed fibrous layers (e.g., sheets) with one another. As a stack of printed fibrous sheets is built up, periodically a holey plate is loaded against the top sheet of the stack. The guide plate may move the sheet down over the registration pins, and then an array of felting needles are thrust into the stack. An array of needles with upward and/or downward facing barbs is thrust thought holes in the guide plate into the stack through printed sheets closest to the guide plate. As the needles pushed into or are withdrawn from the stack, barbs on the felting needles intertwine fibers from the fibrous sheets through printed marking material and with neighboring sheets. The needle array may translate slightly between multiple thrusts so that a subsequent needling thrust may occur in a slightly new location.

Dash Isolation Pad
An embodiment dash isolation pad includes a 3D vertical nonwoven fabric layer having a structure in which wave-type short fibers are vertically arranged, a sound absorption layer on one side or both sides of the 3D vertical nonwoven fabric layer, and an olefin-based powder layer between the 3D vertical nonwoven fabric layer and the sound absorption layer.

Entangled filament molded product
A polymer filament molded product and a method of making a filament network that includes coating filaments with a latex polymer and shaping the filaments into a molded product; one in which a polymer is shaped and molded into a larger filament network. The molded products can be objects for apparel, home and garden, furnishings, health care, engineering, industrial and consumer goods. The molded filament mesh is “fractal” in nature because it is a filament interconnected network at the molecular scale and at the scale of the molded product. The natural tendency of the long molecule filaments to be an entangled structure is maintained.

SCOURING ARTICLE WITH MIXTURE OF ABRASIVE PARTICLES
A scouring article include a three-dimensional non-woven web of fibers bonded to one another to form a lofty, non-woven substrate. An abrasive coating is coated on the substrate. The abrasive coating includes a binder; a first plurality of abrasive particles and a second plurality of abrasive particles dispersed in the binder. The first plurality of inorganic abrasive particles has a Mohs' hardness of 7 greater and a median particle size in the range of 20 microns to 100 microns. The second plurality of organic abrasive particles has a Mobs' hardness in the range of 1 to 5 and a median particle size greater than 100 microns. The average surface roughness created by use of the scouring article, according to the surface roughness test, is less than 8 microns.
