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： The invention relates to a method for the production of high-strength ribbons having a high modulus of elasticity made of a highly molecular polyolefin, wherein the polyolefins, particularly polypropylene and polyethylene, are extruded through a slotted nozzle, are then subjected to a temperature of 85° to 135° C. for a duration of at least one second, the films are then cut into individual ribbons, if necessary, and stretched at temperatures between 90° and 165° C. in one or more steps, are rolled up or further processed directly into textiles or technical flexible sheet materials. The ribbons can be laminated into multi-layer flexible sheet materials by using adhesives or adhesion promoters, the flexible sheet materials being particularly suitable as protection from ballistic projectiles. In this case particularly in the form of plate-shaped or flexible compound bodies.

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.
