A pile fabric includes ground yarns constituting a ground structure; pile fibers that are tangled with the ground yarns, the pile fibers including portions standing on a front surface side of the ground structure; and an organically-modified silicone-based softener adhered to the pile fibers located on a back surface side of the pile fabric. The pile fibers include at least one selected from the group consisting of acrylic fibers and modacrylic fibers, and have a softening point lower than a softening point of the ground yarns. The portions standing on the front surface side of the ground structure are not fused to each other, and on a back surface side of the ground structure, at least part of the pile fibers located outside of the ground yarns are fused to each other.

A membrane for skin comprising a plurality of randomly oriented core-shell nanofibers is provided in the present invention, where each of said core-shell nanofibers comprises at least an active-ingredient-loaded polymeric core and a non-polymeric shell consisting of active ingredients only surrounding the core. Related fabrication method of said membrane is also provided in the present invention.

Lightweight, flexible protective fabrics for protecting a person, animal or other object from hot burning materials, hot high heat capacity and/or hot corrosive materials, such as hot molten metal, hot oily liquids (e.g., heating oil), hot gels, hot solids, hot sparks, and hot acids. The lightweight protective fabrics can be used to protect a person, animal or other object from hot molten metals, such as liquid metal zinc heated to a temperature of about 950 F. (510 C.) or greater, hot molten aluminum heated to a temperature of about 1150 F. (620 C.) or greater, burning phosphorus at temperature of about 1550 F. (843 C.) or greater, hot solid iron having a temperature of about 500 F. (260 C.) or greater, hot heating oil having a temperature of about 500 F. (260 C.) or greater, and hot hydrochloric acid having a temperature of about 300 F. (150 C.) or greater.

Catalyst gauze (1) for the reduction of the amount of N.sub.2O in an ammonia oxidation process, containing a first layer (2) of woven or knitted first wire material (4), whereby said first wire material (4) is made from Pd or a Pd-rich alloy, whereby said first layer (2) contains a reinforcement in the form of a second wire material (5) which is woven or knitted among the first wire material (4) and which has a different composition than the first wire material (5).

A protective material, intended to be applied to skin, is described. It uses at least one polymer layer of a non-woven fabric obtained by electrospinning in an electrostatic field. In one version, the polymer layer uses a mixture of polycaprolactone (PCL) and polyethylene oxide (PEO) with a predominance of polycaprolactone (PCL). The non-woven layer is spot welded. Also described is a protective patch with at least one layer of a polymeric non-woven fabric an adhesive layer and a removable cover layer for the adhesive layer. The polymeric layer is a mixture of polycaprolactone (PCL) and polyethylene oxide (PEO).

Tapes, expanded tapes, and methods of making the same. The tapes and expanded tapes include long-strand PTFE fibrils, short-strand PTFE fibrils, and an oriented network. The oriented network includes nodes. The nodes include short-strand PTPE fibrils. Tapes may include a plurality of through pores. Expanded tapes may include a plurality of through pores.

A biocidal composite wall or surface fabric installable within an aircraft cabin or other vehicle interior space includes a flexible woven layer. The woven layer is treated on its outer surface with a biocidal polymer coating. For example, the polymer coating may incorporate biocidal microcapsules or nanocapsules configured for controlled release of biocidal compounds in response to physical contact or other stimuli. The released biocidal compounds compromise or kill microbial compounds deposited on the outer surface, e.g., via physical contact by passengers or crewmembers. The woven layer includes additional biocidal molecules incorporated into its fibers and strands, the biocidal molecules capable of biocidal action in response to contact with the fabric.

Known catalyst systems for the catalytic combustion of ammonia to form nitrogen oxides consist of a plurality of single- or multilayer catalyst gauzes warp-knitted, weft-knitted or woven from platinum-based noble metal wire, which, when arranged one behind the other in a fresh gas flow direction, form a front group of gauze layers and at least one downstream group of gauze layers arranged after the front group. To provide from this starting point a catalyst system for use in a medium-pressure plant for ammonia oxidation, with which a high service life and a high yield of the main product NO can be achieved, it is proposed that the front group comprises a gauze layer or a plurality of gauze layers made of a first, rhodium-rich noble metal wire, wherein the gauze layer or one of the gauze layers made of the rhodium-rich noble metal wire is a front gauze layer facing the fresh gas, and that the downstream group comprises gauze layers made of a second, rhodium-poor noble metal wire, wherein the rhodium content in the rhodium-rich noble metal wire is at least 7 wt. % and no more than 9 wt. % and is at least 1 percentage point higher than the rhodium content in the rhodium-poor noble metal wire.

A method for producing a two-layer noble metal mesh on a flatbed knitting machine which has a first and a second needle bed. The method comprises: providing at least one wire containing noble metal; and knitting the noble metal mesh. The first and second layers of the noble metal mesh are knitted simultaneously on the first and second needle beds, these two parts being at least in part connected at their two abutting edges by connecting stitches.
