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.

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.

To provide a novel material that maintains suppleness which is the advantage of a material using fibers and has a low thermal shrinkage ratio, and a method for producing the material, a partially welded material using the material, a composite material, and a method for producing a molded product. A material including: a first region, a fiber region, and a second region continuously in a thickness direction; the first region and the second region being each independently a resin layer including from 20 to 100 mass % of a thermoplastic resin component and from 80 to 0 mass % of reinforcing fibers; the fiber region including from 20 to 100 mass % of thermoplastic resin fibers and from 80 to 0 mass % of reinforcing fibers; the thermoplastic resin component included in the first region and the thermoplastic resin component included in the second region each independently having a crystallization energy during temperature increase of 2 J/g or greater, measured by differential scanning calorimetry; and the thermoplastic resin fibers included in the fiber region having a crystallization energy during temperature increase of less than 1 J/g, measured by differential scanning calorimetry; wherein the crystallization energy during temperature increase is a value measured by using a differential scanning calorimeter (DSC) in a nitrogen stream while heating is performed from 25° C. to a temperature that is 20° C. higher than a melting point of the thermoplastic resin component or the thermoplastic resin fibers at a temperature increase rate of 10° C./min.

An aramid fabric having excellent adhesion to a polyurethane matrix resin and excellent tensile strength is produced by the method including the steps of: (i) weaving a basket-structured aramid fabric by using aramid yarns as warp and weft yarns; and then (ii) dipping the woven aramid fabric in a sizing agent solution consisting of an aqueous polyurethane resin as a sizing agent and water, followed by squeezing and drying. In the present disclosure, the sizing agent is applied to the woven aramid fabric, thereby effectively preventing the deterioration in weaving efficiency. Further, the aramid fabric is woven in a basket weave, and thus the compactness of the aramid fabric is lowered and the wetting property of the aramid fabric with the polyurethane matrix resin is improved.

A vehicle component that includes at least one fiber preform. The fiber preform includes a substrate, a fiber bundle having one or more types of reinforcing fibers, and a thread. The fiber bundle is arranged on the substrate and attached to the substrate by a plurality of stitches of the thread to form a first preform layer having a principal orientation. The vehicle component includes a core having a geometry with at least one edge and at least one the fiber preforms positioned along the at least one edge, the core and the fiber preform being overmolded in a resin. A process of making the vehicle component includes providing the core having the at least one edge, positioning the at least one fiber preform along the at least one edge, and overmolding the core and the at least one fiber preform in the resin.

A continuous process for the recycling of aramid fiber comprising the following steps: combining aramid fibrous material including non-continuous aramid fibers with sulfuric acid to obtain a spin dope comprising aramid, and processing the spin dope including aramid into a continuous aramid fiber. The invention also pertains to a continuous aramid fiber, preferably obtainable by said process, and to a multifilament yarn including the continuous aramid fiber.

A core wire for a power-transmission belt includes a plied twisted cord formed by putting together and secondary twisting a plurality of primary twisted yarns. The primary twisted yarns include a plurality of hard primary twisted yarns (A) and one soft primary twisted yarn (B). The hard primary twisted yarns (A) include an aramid fiber, and a fineness of each hard primary twisted yarn (A) is 1500 dtex or less. The soft primary twisted yarn (B) includes a low elastic modulus fiber. A ratio (B/A) of a primary twist coefficient of the soft primary twisted yarn (B) to an average value of primary twist coefficients of the hard primary twisted yarns (A) is 0.5 to 1.2.

A printed sheet fiber entanglement apparatus entangles fibers from neighboring printed fibrous layers (e.g., sheets) with one another. As a stack of printed fibrous sheets is built up, periodically a holey plate is loaded against the top sheet of the stack. The guide plate may move the sheet down over the registration pins, and then an array of felting needles are thrust into the stack. An array of needles with upward and/or downward facing barbs is thrust thought holes in the guide plate into the stack through printed sheets closest to the guide plate. As the needles pushed into or are withdrawn from the stack, barbs on the felting needles intertwine fibers from the fibrous sheets through printed marking material and with neighboring sheets. The needle array may translate slightly between multiple thrusts so that a subsequent needling thrust may occur in a slightly new location.

The present invention is directed to a three-dimensional composite fabric including a three-dimensional woven fabric, and a nonwoven fabric arranged on a first, on a second side, or on both sides of the three-dimensional woven fabric, wherein the composite fabric retains at least 15% thickness at a compression of about 200 pounds per square foot (psf) to about 1000 pounds per square foot. Further, the present invention is directed to a method of making a three-dimensional composite fabric and a method of installing the three-dimensional composite fabric in a landfill.
