The invention includes a meth of manufacturing an almost invisible coated monofilament, the coated monofilament, and a screen created using the almost invisible coated monofilaments. The method includes the step of selection a clear monofilament having a first perpendicular index of refraction, and selecting a clear elastomer coating having a second perpendicular index of refraction, where the two index of refraction are within 2% of one another. The monofilament is coated by extrusion coating using a tube die, where a vacuum is applied to the thread entrance or threadway of the extrusion system prior to coating.

A woven gauze fabric excellent in balance between breathability and heat-retaining property, transparency preventing property, and good touch feeling (softness). The woven gauze fabric includes a surface layer G.sub.1 and a back layer G.sub.3, wherein the layer G.sub.1 and G.sub.3 are directly and/or indirectly joined together. The layer G.sub.1 is formed of a hollow yarn having a yarn count of 30-50 (both inclusive), and the layer G.sub.3 is formed of a hollow yarn having a yarn count of 30-50 (both inclusive). In a case where the woven gauze fabric is a triple gauze including a middle layer G.sub.2, the hollow yarn of the layer G.sub.1 and G.sub.3 have a yarn count of 40-50 (both inclusive). In a case where the woven gauze fabric is a double gauze, the hollow yarn of the layer G.sub.1 and G.sub.3 have a yarn count of 30-40 (both inclusive).

A new and improved gas fired burner unit that can be utilized in applications where low emissions and high efficiency are desired including a burner body having a lower housing unit with a bottom portion, a distribution element located above the bottom portion, a burner deck located above the distribution element, and a metal fiber mesh element located above the burner deck. The burner deck supports the metal fiber mesh and spaces the metal fiber mesh from the internal distribution element to define a burner head. At least one inlet conduit communicates with the burner body and extends into the burner body to deliver a gas/air mixture to the burner body in a region located below the distribution element and above the bottom portion of the lower housing unit. The burner head has a permeability greater than 700 liters per hour, and the bottom portion of the lower housing unit includes a plurality of ribs providing added rigidity to the burner body and eliminating combustion noise.

A stabilized fabric composed of a mesh or a woven fabric is disclosed as are methods of their manufacture, the manufacture of medical devices made using a stabilized fibers and stabilized medical devices are all disclosed. Fabrics can be stabilized by several techniques including: using mechanical, chemical and/or energetic fasteners at warp and weft intersections in the weave; by using various weaving techniques and fibers. Meshes can be stabilized when properly dimensioned and arranged junctions and struts of the necessary properties are used. All of these stabilized fabrics can be made of synthetic polymer materials such as ultrahigh molecular weight PE or PP and expanded PTFE.

A flexible sheet collects overspray and keeps spray booth environments clean, thereby reducing or eliminating dust and foreign matter from landing on wet painted surfaces which might otherwise result in a paint surface defect. The flexible sheet comprises a woven or non-woven mesh or net material having apertures or perforations that penetrate through the sheet. The sheet is impregnated with a tacky substance, such that paint overspray and dirt particles cling to the impregnated sheet. In the preferred embodiment, the tacky substance is a wax-based substance, more preferably a natural or synthetic beeswax-based substance. The material may be made from polymeric filaments of nylon or other natural or synthetic fibers, threads or strands. The flexible sheet of material may be provided in roll form for use. Method of making a tacky netting are also disclosed. The product is particularly useful in vehicle spray-booth applications.
