A fabricated part for a high temperature operation including a non-metallic substrate formed of a polymer fabric of woven non-absorbent polymer filament. The substrate is heat-resistant and heat set at a temperature that is above a predetermined operating temperature of an operation of the fabricated part. The heat setting pre-shrinks/heat stabilizes the material, thereby reducing failure during use in high temperature and/or wet applications. The substrate is useful as an endless belt and other applications. The invention further includes an apparatus with a heating device configured to operate at the predetermined operating temperature, and the fabricated part within or extending through the heating device.

An industrial textile is provided, preferably suitable for use as a dryer fabric in a papermaking machine.

Additionally, each of the warp yarns in the second system of warp yarns is interwoven with the system of weft yarns with a float on the second surface under at least 5 of the weft yarns, over 1 of the weft yarns, under 1 of the weft yarns, and over 1 of the weft yarns in the repeating pattern. Each of the warp yarns of the first system of warp yarns is stacked over a corresponding one of the warp yarns of the second system of warp yarns to form stacked pairs of the warp yarns.

The present invention discloses a high-performance PPS fiber structure and production method and use thereof. The high-performance PPS fiber structure is woven fabric made from PPS fibers in 0.1 to 12 m cross sectional diameter, and the maximum pore size of the PPS fiber structure is 20 m or smaller. The PPS fiber structure disclosed in the present invention has the advantages of high gas impermeability and good hydrophilicity, also has the advantages of simple process, low energy consumption and zero environmental pollution, and can be used in diaphragms for electrolytic apparatuses, high-temperature liquid filter materials and insulating materials.

A textile material comprises a plurality of yarns, the yarns containing an intimate blend of dyed polyphenylene sulfide fibers and cellulosic fibers. The dyed polyphenylene sulfide fibers comprising a disperse dye that is distributed substantially evenly across the cross-sectional area of the fibers. A method for dyeing textile materials containing polyphenylene sulfide fibers comprises the steps of (a) providing a textile material comprising yarns which contain an intimate blend of polyphenylene sulfide fibers and cellulosic fibers, (b) providing a dye liquor comprising a liquid medium and a disperse dye, (c) applying the dye liquor to the textile material, (d) heating the textile material under ambient atmosphere to a temperature sufficient to evaporate substantially all of the liquid medium from the textile material, and (e) heating the textile material under ambient atmosphere to a temperature of about 180? C. or more to fix the disperse dye to the polyphenylene sulfide fibers.

A fabric for reinforcing a power transmission belt including fibers of polyarylene sulfide and a belt utilizing the fabric. The fabric may have textured or elastic core wrapped stretch yarns in the longitudinal direction. Longitudinal yarns may include PPS and textured transverse yarns include nylon. Yarns may include blends of high performance fibers and nylon or other fibers.

Woven and knit fabrics containing expanded polytetrafluoroethylene (ePTFE) fibers and at least one other fiber are provided. The ePTFE fiber may be woven or knit as a single, non-twisted fiber, as part of a multifilament fiber, or may be twisted or braided with another fiber. The ePTFE fiber, whether alone or in combination with a weave fiber(s), may be utilized in either the warp and/or the weft direction. The woven and knit fabrics are concurrently breathable, lightweight, durable, drapable, and fast drying. The ePTFE fibers have a substantially rectangular configuration. In some embodiments, the woven or knit fabric is flame resistant. In addition, the woven and knit fabrics are quiet, soft, and drapable. Treatments may be provided to the surface of the ePTFE fiber and/or the fabrics to impart one or more desired functionality, such as, for example, oleophobicity, anti-microbial, contamination resistance, or UV stability.

A forming fabric for a papermaking machine woven according to a repeating fabric weave pattern is provided. The fabric includes a PS layer having a PS surface, with the PS layer including PS warps and PS wefts interwoven in a first repeating pattern, and a MS layer having a MS surface, with the MS layer including interwoven MS warps and MS wefts. A plurality of pairs of binder weft yarns is provided, with each of the pairs of binder weft yarns comprising first and second binder weft yarns that are interwoven according to a binder weft pattern with the PS warps and the MS warps to bind the PS and MS layers together in the composite forming fabric, and each interchanges between the layers at exchange points. In each pattern repeat of the fabric weave pattern, each of the MS warps forms one or more MS warp knuckles over single ones of the MS wefts, the MS warp knuckles of the MS warps are arranged in a broken twill having an offset mirror symmetric arrangement, and a direction of the broken twill reverses after an equal number of MS warp knuckles.

The present disclosure relates to a spinneret for producing hollow fiber membranes in a phase inversion process.

A down-proof woven fabric includes a cloth composed of synthetic fibers with a yarn fineness of 33 decitex or less and having a weight per unit area of 50 g/m.sup.2 or less and a cover factor of 1,400 to 1,800, wherein the cloth is coated at least on one surface thereof with a resin by an amount of 0.1 g/m.sup.2 to 5 g/m.sup.2 as a solid component.

A clothing for a machine producing and/or processing a fibrous web extending in longitudinal and widthwise directions, includes a basic structure providing dimensional stability in longitudinal and/or widthwise directions. The structure includes a band-shaped, one-piece grid having widthwise-adjacent first material strands and polymer material having lengths in a longitudinal direction, and adjacent second interconnected material strands and/or droplets and polymer material, contacting the first strands at contact points forming the grid. The strands and/or droplets are deposited by extrusion of the polymer materials in liquid or pasty state onto a depositing surface forming a portion or all of the grid in liquid or pasty state, the polymer materials are solidified, converting the portion or the grid from liquid or pasty to solidified, stable, self-supporting state producing bonding at the contact points, and removing the portion or the grid from the surface.
