Abstract: The present invention is directed to a low-density substrate, which has an optimized pore volume distribution. The optimized pore volume distribution allows the substrate to hold at least 50 percent of its cumulative volume within pores with a radius size of about 110 to 250 microns. The optimized pore volume distribution can also be characterized by having a dry fibrous web that absorbs less than 20 percent of the cumulative volume of the fibrous web at a pore radius of 75 microns. The optimized pore volume distribution of the substrate enables it to controllably release a fluid composition effectively onto a surface. The basis weight of the substrate is about 80 to 20 gsm and the density of the substrate is below 0.1 g/cc. The substrate may be a pre-loaded wipe, which is either moistened by a consumer prior to use or moistened prior to packaging. The composition loaded onto the substrate may contain dry and/or liquid compositions preferably for cleaning hard or soft surfaces.

Abstract: The inventive method provides highly desirable hand to various different types of fabrics through the initial immobilization of individual fibers within target fabrics and subsequent treatment through abrasion, sanding, or napping of at least a portion of the target fabric. Such a procedure includes “nicking” the immobilized fibers thereby permitting the fibers to produce a substantially balanced strength of the target fabric in the fill and warp directions while also providing the same degree of hand improvements as obtained with previous methods. Furthermore, this process also provides the unexpected improvement of non-pilling to synthetic fibers as the “nicking” of the immobilized fibers results in the lack of unraveling of fibers and thus the near impossibility of such fibers balling together to form unwanted pills on the fabric surface. Fabrics treated by this process are also contemplated within this invention.

Abstract: A belt reinforcing fabric for conveyor belts including sets of longitudinal warp yarns that are woven in leno weave fashion about lateral weft yarns that are made of monofilament. For each area on the fabric including sets of warp yarns, there is also an adjacent area that does not include warp yarns. Therefore, a space or gap is created between the areas occupied by the sets of warp yarns. When the belt is cut, it can be cut along the gap so that only the monofilament weft yarns are visible along the edges and not the warp yarns, which, if exposed at the cut edges, would tend to wick moisture into the belt. The present conveyor belt is particularly useful in conveying food items because of its tendency to reduce the opportunity to pick up and spread contaminating agents such as bacteria.

A synthetic turf product may be constructed by tufting the composite backing.

Abstract: Specific fabric articles exhibiting very low air and/or gas permeability (even upon application of high inflation pressures) and very high tear strengths are herein disclosed and claimed. Such a specific fabric also permits the incorporation of discrete openings (through cutting, for example) through which air and/or gas introduced by an airbag inflation canister will travel. Such a specific fabric acts as a barrier to the complete introduction of high pressure inflation gases into an airbag cushion, thereby permitting a more controlled, safer inflation upon the occurrence of a collision event. Thus, the specific inventive fabric permits movement of inflation gas and/or air substantially solely through the openings within the fabric and not through the interstices between the individual fiber constituents.

Abstract: Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeabilities. The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 3.0 ounces per square yard, most preferably about 0.8 ounces per square yard, and exhibits a leak-down time (a measurement of the time required for the entire amount of gas introduced within the airbag at peak pressure during inflation to escape the airbag at 10 psi) of at least 7 seconds.
