An article comprising a fabric comprising: (a) a blended yarn comprising: (i) from about 10% to about 85% by weight of at least one biregional fiber comprising an oxidized polymer selected from the group consisting of acrylonitrile based homopolymers, acrylonitrile based copolymers, acrylonitrile based terpolymers, and combinations thereof; (ii) at least one companion fiber selected from the group consisting of FR polyester, FR nylon, FR rayon, FR treated cellulose, m-aramid, p-aramid, modacrylic, novoloid, melamine, wool, nylon, regenerated cellulose, polyvinyl chloride, antistatic fiber, poly(p-phenylene benzobisoxazole) (PBO), polybenzimidazole (PBI), polysulphonamide (PSA), and combinations thereof; and (b) optionally including a companion yarn different from said blended yarn; wherein said companion yarn includes p-aramid in an amount less than 20% of the fabric weight; and
wherein the fabric has a weight from about 3 oz/yd.sup.2 to about 12 oz/yd.sup.2.

A fabric for use in arc and flame protection, and a process for producing a fire resistant fabric are provided. The fabric is comprised of at least 70 weight percent (wt%) aramid fiber; less than 40 wt% modacrylic; 8 wt% nylon; and 2 wt% anti-static. The process comprises shredding recycled fire resistant garments into fibers; creating yarn from the shredded fibers; weaving the yarn into fabric; and knitting the yarn to produce new garments. The fabric may be used to produce fire-resistant garments worn by workers in many industries such as the oil and gas.

A warp knitted mesh fabric constructed of synthetic, or synthetic and natural, fibers is characterized by having a low density, open construction with a high profile for spacing a garment constructed from the fabric from the skin of a wearer of the garment.

The present invention relates to flame retardant fabrics and safety apparel, especially yarn used for high flame resistant safety apparel fabric wherein the yarn uses a cheese method and the yarn is used to weave fabric. The fabric as described contains at least 60% high flame resistant modacrylic fiber which after cheese dyeing is woven into fabric. The safety apparel that use this fabric will not continue to burn after leaving a fire, will not melt or cause the wearer secondary injury and complies with the relevant standards of the European Union, the United States and China.

A pile fabric includes a long pile portion and a short pile portion. An average pile length of the long pile portion differs from an average pile length of the short pile portion by 2 mm or more. The long pile portion contains crimped polyester-based fibers in an amount of 60% by weight or more. The short pile portion contains crimped polyester-based fibers in an amount of 60% by weight or more. A crimp removal temperature of the polyester-based fibers of the long pile portion is lower than a crimp removal temperature of the polyester-based fibers of the short pile portion. The crimp removal temperature of the polyester-based fibers of the short pile portion is 90° C. or more and 120° C. or less. Each of the crimp removal temperatures indicates a minimum temperature that satisfies a specific relationship. A method for manufacturing the pile fabric is also provided.

A fabric for arc-protective garments includes first yarns and second yarns different from the first yarns. The first yarns include first modacrylic fibers, and the first modacrylic fibers contain an infrared absorber in an amount of 2.5 wt % or more with respect to a total weight of the first modacrylic fibers. The weight of the infrared absorber per unit area in the fabric for arc-protective garments is 0.05 oz/yd.sup.2 or more. An arc-protective garment includes the fabric for arc-protective garments.

A flame-retardant fiber composite includes an acrylic fiber A containing an acrylic copolymer and an aramid fiber. The acrylic fiber A is substantially free of an antimony compound, and the flame-retardant fiber composite forms a surface-foamed char layer when burned. A flame-retardant work clothing includes the flame-retardant acrylic fiber. A highly flame-retardant fiber composite and highly flame-retardant work clothing include an acrylic fiber, and are capable of exhibiting high flame retardancy while suppressing environmental impacts caused by a flame retardant.

The present invention relates to a flame-retardant fabric that includes modacrylic fibers, one or more of regenerated cellulose fibers selected from the group consisting of flame-retardant rayon fibers and lyocell fibers, and polyimide fibers. The flame-retardant fabric includes the modacrylic fibers in an amount of 26 to 79 wt%, the regenerated cellulose fibers in an amount of 18 to 48 wt%, and the polyimide fibers in an amount of 3 to 26 wt%. The polyimide fibers have a fiber length of 45 to 127 mm. The char length measured by a flammability test based on GB/T 5455-1997 is 50 mm or less. The present invention also relates to protective clothing made of the flame-retardant fabric. Thus, the present invention provides a flame-retardant fabric whose char length is short in a flammability test and that has favorable flame retardancy, and protective clothing made of the flame-retardant fabric.

A yarn comprising a plurality of bicomponent filaments having a first region comprising a first polymer composition and a second region comprising a second polymer composition, each of the first and second regions being distinct in the bicomponent filaments; each bicomponent filament comprising 5 to 60 weight percent of the first polymer composition and 95 to 40 weight percent of the second polymer composition; wherein the first polymer composition comprises aramid polymer containing 0.5 to 20 weight percent discrete homogeneously dispersed carbon particles and the second polymer composition comprises modacrylic polymer being free of discrete carbon particles; the yarn having a total content of 0.1 to 5 weight percent discrete carbon particles.

In one or more embodiments, the present invention relates to a resin composition containing at least a polymer (A) and a polymer (B), in which the polymer (A) is a polymer that includes one or more monomers selected from the group consisting of acrylonitrile, vinyl halides, and vinylidene halides, the polymer (B) is a polymer that is soluble in benzyl alcohol, and the resin composition contains the polymer (A) in an amount of 70 parts by mass or more and 92.5 parts by mass or less, and the polymer (B) in an amount of 7.5 parts by mass or more and 30 parts by mass or less, where a total amount of the polymer (A) and the polymer (B) is 100 parts by mass. Provided are synthetic fibers that are easily dyeable with an acidic dye without requiring use of a special facility or heating to high temperatures.
