A method for producing a nonwoven fabric is provided. The method includes spinning a molten aromatic polysulfone resin from a nozzle and extending it with a high temperature fluid ejected at high speed, thereby obtaining the aromatic polysulfone resin in a fibrous form, and collecting the aromatic polysulfone resin obtained in a fibrous form on a moving collecting member. The aromatic polysulfone resin has a melt mass flow rate of 130 g/10 min or more under conditions of a test temperature of 400° C. and a nominal load of 2.16 kg, which is determined based on ASTM D 1238. A distance from the nozzle to the collecting member is set to 30 mm or less.

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.

A wrappable woven sleeve includes a wall having opposite edges extending lengthwise between opposite ends. The opposite edges are configured to be wrapped about a central longitudinal axis, whereupon the wall takes on a tubular configuration with an inner surface of the wall bounding an enclosed cavity sized for receipt of an elongate member to be protected therein and an outer surface of the wall facing radially outwardly from the central longitudinal axis. The wall is woven with warp filaments extending generally parallel to the central longitudinal axis and weft filaments extending generally transversely to the warp filaments. One or more of the warp filaments are wire to shield against passage of low frequency EMI. A foil layer is fixed to the outer and/or inner surfaces of the wall to shield against passage of high frequency EMI.

A multilayer textile for a sandwich structure includes skins made of a fiber-reinforced resin and a core that is sandwiched by the skins. Skin portions are each configured by a warp and a weft both made of a reinforcement fiber. A core portion is configured by a warp and a weft both made of a fiber that is insoluble in a matrix resin of the skins and has a smaller specific gravity than the reinforcement fiber. The skin portions and the core portion are integrated by a binding yarn that is insoluble in the matrix resin of the skins.

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.

The invention provides a woven textile having a first and second side and comprising a plurality of yarns, wherein at least a portion of the yarns comprise an intimate blend of at least about 51% by weight polyphenylene sulfide fibers, less than about 49% by weight para-aramid fibers, and, less than about 2% by weight meta-aramid fibers. The polyphenylene sulfide, para-aramid, and meta-aramid fibers are staple fibers with an average staple fiber length of between about 20 and 100 mm.

A protective textile sleeve for providing protection to an elongate member contained therein; a method of construction thereof, and a method of bonding at least a portion of the sleeve to at least one of itself and an elongate member extending through a cavity thereof is provided. The sleeve has a wall of interlaced yarn, with the wall having an outermost surface and an innermost surface. The innermost surface is configured to bound a cavity extending between opposite open ends. The sleeve further includes an adhesive coating bonded to at least a portion of at least one of the outermost and innermost surfaces. The adhesive coating has a first, dried non-adhesive state and a second, wetted adhesive state, wherein the second adhesive state is activated via application of a water-based liquid thereto.

Dimensionally-stable fibrous structures including ceramic-coated melt-blown nonwoven fibers made of a flame-retarding polymer and processes for producing such fire-resistant nonwoven fibrous structures. The melt-blown fibers include poly(phenylene sulfide) in an amount sufficient for the nonwoven fibrous structures to pass one or more fire-resistance test, e.g. UL 94 V0, FAR 25.853 (a), FAR 25.856 (a), and CA Title 19, without any halogenated flame-retardant additive, and have a ceramic coating. The melt-blown fibers are subjected to a controlled in-flight heat treatment at a temperature below a melting temperature of the poly(phenylene sulfide) immediately upon exiting from at least one orifice of a melt-blowing die, in order to impart dimensional stability to the fibers. The nonwoven fibrous structures including the in-flight heat-treated melt-blown fibers exhibit a Shrinkage less than a Shrinkage measured on a nonwoven fibrous structure including only fibers not subjected to the controlled in-flight heat treatment operation, generally less than 15%.

A dryer fabric has a weft of cross machine direction yarns (6) and a first warp of first machine direction yarns (5) and a second warp of second machine direction yarns (9). The yarns of the first warp are arranged above the yarns of the second warp on a first surface (FS) side. The first warp has primary yarns (51) of PPS or PK yarns whose breaking load remains substantially stable within 15 days in conditions where RH=100%, T=125° C. and p=2.3 bar; and secondary yarns (52) of PET with breaking loads which substantially decrease under the same conditions. At least every second yarn of the first warp is a secondary yarn (52). The secondary yarns (52) may be two out of three or three out of four of the first machine direction yarns (5). PET reduces cost and adds elasticity to the dryer fabric.

A filter element comprising two layers of weft (1) interlaced with warp (2). Additionally laid-in (3) yarns are provided in-between the two weft layers. The laid-in yarns (3) are not interlaced with the weft.
