    摘要： An abrasive cloth which comprises an article in a sheet form having, in at least a part thereof, nanofibers comprising a thermoplastic polymer and having a number average single fiber fineness of 1×10−8 to 2×10−4 dtex wherein the sum of single fiber fineness percentages (which is defined in the specification) of a single fiber fineness of 1×10−8 to 2×10−4 dtex is the range of 60% or more, and exhibits a stress at 10% elongation in a longitudinal direction of 5 to 200 N/cm-width; and a method for preparing a nanofiber structure, which comprises providing a nanofiber dispersion having a dispersant and, dispersed therein, nanofibers comprising a thermoplastic polymer and having a number average diameter of 1 to 500 nm, attaching the dispersion to a support, and then removing said dispersant. The above abrasive cloth is excellent in texturing characteristics, and the above method allows the preparation of a nanofiber structure wherein nanofibers form a composite with the support.

    摘要： The present invention relates to acrylic sulfide fibers whose tensile strength is at least 3.5 g/d, toughness expressed by TE.sup.1/2 product of tensile strength (T g/d) and a square root of tensile elongation (E %), is higher than 10 and sulfur content is higher than 0.5 weight %, a process for producing acrylic sulfide fibers characterized by heating acrylic fibers whose tensile strength is at least higher than 7 g/d in sulfur-containing atmosphere, and composite materials being reinforced with above described acrylic sulfide fibers.Acrylic sulfide fibers obtained have high tenacity and high toughness as well as excellent heat resistance, anti-flammability and alkali resistance.Therefore, above described acrylic sulfide fibers are useful for such applications as heat resistant and flame resistant spun-woven products, reinforcing cement cured in an autoclave and abrasive materials as asbestos substituting fibers.
