摘要:
A particulate filtration system is provided for protecting a substrate to be painted from wet or dry particulates the result from overspray. The filtration system includes a particulate filter, a grate, and a two-dimensional prefilter. The filtration system can be used, for example, in spray painting booths for painting vehicles.

A protection sheet and method of protecting a substrate is disclosed. In an embodiment, the protection sheet comprises an adhesive coated nonwoven material. In an embodiment a surface of the protection sheet captures and retains paint overspray, dust, dirt and other contaminants so as to provide a cleaner paint job. In an embodiment the protection sheet may be laminated to a second nonwoven or woven material to allow clean removal after extended use. The protection sheet may be used to protect horizontal or vertical substrates, and is particularly suited to protect the surfaces of a paint booth used in automotive spray-painting operations.
摘要:
The present invention is directed at a hook mechanical fastener/fibrous composite comprising hook elements on hook containing backing elements or a netting embedded in a fibrous web. The hook elements preferably are on backing elements that are connected or integral and can be strands oriented at angles to each other in a net form. The backing elements generally have a first outer face and a second outer face. The backing elements on at least one of the first or second outer faces have a plurality of hook elements. The hook containing backing elements are embedded within a fibrous web, preferably by hydroentangling the fibers around the backing element, preferably without use of auxiliary attachment means such as adhesives or point bonding.
摘要:
An efficient, economical, compact diesel particulate trap has a plurality of perforated hollow tubes, on each of which a heat-resistant yarn is helically cross-wound to provide a plurality of layers that function as a filtering element. The yarn, which preferably is a continuous-filament ceramic yarn, has a core from which filaments or fiber segments project outwardly and intermesh with fiber segments of laterally spaced cores to provide traps. The cores of yarn convolutions of at least one layer are laterally offset from the cores of convolutions of an adjacent layer to deflect into tortuous paths gases flowing generally radially through the filtering element.
