    摘要: A nonwoven fabric including fibers that contain a polymer having a glass transition temperature of greater than or equal to 50° C. as a main component, and having a vertical strength of greater than or equal to 1 N/5 cm per 1 g/m2, and by satisfying both of the following conditions (1) and (2), a nonwoven fabric having sufficient strength to be handled alone and including fibers that contain a polymer having a Tg of greater than or equal to 50° C. as a main component without performing a post processing such as emboss processing, calender processing, or spunlace processing, and a method for producing the nonwoven fabric can be provided. (1) A density is 0.01 to 0.4 g/cm3. (2) A proportion of parts with a density exceeding 0.4 g/cm3 is less than or equal to 3% in a cross section in a thickness direction.

    摘要: A melt spinning apparatus includes an apparatus body and a nozzle for extruding melted resin, a primary hot air passage formed around the nozzle, and a secondary hot air passage formed in a zone outside of the primary hot air passage, which are formed in the apparatus body. The primary hot air passage discharges primary hot air onto fibers of the melted resin extruded from the nozzle. The secondary hot air passage discharges secondary hot air to maintain the temperature of the primary hot air. The discharge angle of the secondary hot air from the secondary hot air passage is set in a range of 0° to 50° with respect to the direction of the melted resin extruded from the nozzle. The secondary hot air forms an air curtain that blocks the atmospheric air.

    摘要: A polyvinyl chloride-based fiber of the present invention is a fiber formed with a vinyl chloride resin composition that comprises (a) 100 parts by weight of vinyl chloride resin, and (b) 0.2 to 20 parts by weight of crosslinked vinyl chloride resin in which a weight fraction of constituents that are insoluble in tetrahydrofuran is 18 to 45% and a viscosity average degree of polymerization of constituents that are soluble in tetrahydrofuran is 500 to 1800, in which a cross-sectional shape of the fiber comprises a combination of at least two of circles, ellipses, and parabolas. When this fiber is used as artificial hair, it is possible to provide style changeability without impairing matte properties and touch of the vinyl chloride-based fiber. Furthermore, the fiber of the present invention can be produced stably by melt-spinning, and thus an industrial advantage also is provided.
