A flame resistant knit fabric containing a first weft yarn set and a second weft yarn set. The first yarn set contains first flame resistant yarns which contain flame resistant rayon fibers. The second weft yarn set contains second weft yarns. The knit fabric is knitted such that the first weft yarns are interlinked with one another by a plurality of knit stitches, the second weft yarns are interlinked with one another by a plurality of knit stitches, and the first weft yarns are not interlinked with the second weft yarns. A flame resistant support article containing the flame resistant knit fabric as well as methods for making the knit fabric and support article are also disclosed.

A process for manufacturing a fiber including meta-aramid having a breaking tenacity of at least 300 mN/tex including the steps of preparing a spin dope including meta-aramid and sulfuric acid having a concentration of at least 80 wt % and passing the spin dope through a spinneret into a coagulation bath, wherein the spin dope has a meta-aramid concentration of at least 10 wt %. The invention also pertains to a meta-aramid fiber, a multifilament yarn, a textile sheet and protective clothing.

Flame resistant fabrics formed with a combination of body yarns and stretch yarns that exhibit excellent physical and thermal properties. The body yarns are formed at least in part with flame resistant materials. The stretch yarns are corespun yarns having an elastic core surrounded by a fiber sheath formed at least in part with flame resistant materials. The fiber sheath protects the elastic core from direct exposure to heat and flame that would otherwise cause the core to degrade or melt.

The invention relates to a process for manufacturing a multilayer knitted textile by heating a multi-layer knitted textile in the presence of one or more dye compounds, wherein the multilayer knitted textile comprises a fabric outer layer and a fabric inner layer, wherein the fabric outer layer is knit from a first yarn containing a combination of modacrylic fibers and cotton fibers, wherein the fabric inner layer is knit from a second yarn made from 50-90% HBA/HNA filaments, wherein the heating shrinks the outer layer from about 5 to 25% in length, width, or both.

Flame resistant fabrics formed with fiber blends that provide the requisite flame and thermal protection but that have improved durability. In some embodiments this is accomplished with the use of fiber blends that include relatively large percentages of FR nylon fibers in combination with cellulosic and inherently flame resistant fibers.

Described are composite articles containing heat stable spun yarn containing textiles that exhibit low flammability and thermal shrinkage resistance. A composite article is described comprising (1) a textile layer comprising a heat stable spun yarn and (2) a heat reactive layer. The articles can be National Fire Protection Agency (“NFPA”) 2112 compliant.

A fabric for use in arc and flame protection, and a process for producing a fire resistant fabric are provided. The fabric includes at least 70 wt % aramid fiber; less than 40 wt % modacrylic; 8 wt % nylon; and 2 wt % anti-static. The process includes 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.

Described herein are high visibility yarns and fabrics along with methods and making and using the same.

The invention relates to a filament having flame retardant properties, as well as methods for its preparation and its use. The filament according to the invention are Lyocell filaments.

The disclosure discloses a washable flame retardant viscose fabric. The viscose fabric includes a flame retardant viscose fiber; and a method of preparing the viscose fiber includes the following steps: impregnation, squeezing, ageing, yellowing, addition before spinning, spinning, bundling, drafting, cutting off, first washing, desulfurization, second washing, pickling, third washing, application of oil bath, drying, and packaging. Before spinning, an aqueous dispersion of flame retardant, an aqueous dispersion of hyperbranched nanocellulose and a dispersant are uniformly added to a spinning glue using a pre-spinning injection system. During the production of the flame retardant viscose used, the aqueous dispersion of flame retardant, the aqueous dispersion of hyperbranched nanocellulose and the dispersant are introduced into the spinning glue by the pre-spinning injection system before spinning, so that the flame retardant has a high residual rate in the subsequent coagulation bath.
