The present invention relates to a polyolefin fiber comprising polymeric structures, wherein the polymeric structures individually comprise a polycondensate and a functionalized polymer, and the polyolefin fiber is a gel-spun high-performance polyethylene fiber that has a tenacity of at least 1 N/tex. The polymeric structures are immiscible with and dispersed in the polyethylene fiber. The gel-spun high-performance polyethylene fiber is a gel-spun ultrahigh molecular weight polyethylene fiber. The present invention further relates to a process for making the polyolefin fiber comprising the steps of: melt-mixing the polycondensate or a polycondensate containing at least one additive, the functionalized polymer, and optionally the thermoplastic polymer and/or the at least one additive, to form polymeric structures; mixing polyolefin powder, the polymeric structures and a solvent to form a mixture; and spinning and drawing the mixture obtained in step ii) to form the polyolefin fiber comprising the polymeric structures.

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.

The present invention can provide a fiber-reinforced expanded particle molded article having a reinforcing material fused and integrated with the surface of an expanded molded article, wherein the reinforcing material is a fabric or a braided product produced by weaving a linear composite material produced by melting and integrating a thermoplastic fiber comprising a low-melting component fiber and a high-melting component fiber, as two or more threads selected from the group consisting of a warp, a weft and a slant thread, the fiber-reinforced expanded particle molded article exhibiting an excellent reinforcing effect; and a method for economically producing the molded article by in-mold molding with a small number of steps.
