    Abstract: A method is provided for producing solid material filaments or films from a fluid of the material, by extruding the fluid by one or more extrusion openings and by solidifying the material in a precipitation bath. The formed material is guided between the extrusion openings and the precipitation bath by a lateral gas flow. The gas flow is subdivided into a hot partial flow and a cold partial flow. The material is initially brought into contact with the hot partial flow and subsequently with the cold partial flow prior to it being introduced into the precipitation bath. A device is also provided for extruding and forming materials.

    Abstract: This invention relates to a yarn having high moisture regain for use in arc and flame protection and fabrics and garments containing the yarn. The yarn has a blend of fibers which includes 10 to 40 weight percent meta-aramid fiber having a degree of crystallinity of at least 20%, 20 to 60 weight percent modacrylic fiber, 15 to 45 weight percent FR rayon fiber, and (d) 5 to 20 weight percent para-aramid fiber; based on the total weight of these components. If desired, 1 to 3 weight percent of the para-aramid fiber in the yarn can be replaced with an antistatic fiber as long as at least 5 weight percent para-aramid fiber is present.
