Abstract: The present invention relates to a polyvinyl chloride-based resin fiber having a shrinkage stress of 70 ?N/dtex or less at 130° C. When fiber bundles for artificial hair which includes 20 to 100% by weight of this polyvinyl chloride-based resin fiber and 0 to 80% by weight of a thermoplastic resin fiber having a Young's modulus of 4 to 9 GPa and a shrinkage percentage of 10% or less at 130° C. and having a composition including no polyvinyl chloride-based resin are processed, a fiber for artificial hair and an artificial hair product having an excellent styling property and texture similar to those of human hair can be obtained.

Abstract: The invention relates to a method and an apparatus for producing a film web made of thermoplastic material in which the thermoplastic material is extruded in at least one layer as plastic melt from a wide-slit nozzle in an extrusion direction and subsequently led away over at least roller, wherein tensile forces are exerted in the extrusion direction and transversely to the extrusion direction in order to stretch the film web longitudinally and transversely, wherein during application of the tensile forces in and transversely to the extrusion direction the film web has a temperature at least corresponding to the melting temperature of the same.

Abstract: Embodiments of the invention may include one or more high-density textile fibers with a density from about 1 to about 11 g/mL. Some embodiments may include fabrics and/or garments made from such fibers. Embodiments comprising garments can include, for instance, exercise aids for providing extra mass to the wearer. Other embodiments can comprise, without limitation, building materials, safety equipment, armor, body armor, protective apparel, marine repair materials, marine protective devices, boat hulls, vehicle chassis, or blast-resistant materials.

Abstract: The present invention provides micro- and nanofibers made from polymers that comprise nanoparticles, such as carbon nanoparticles and inorganic nanoparticles, and methods of making such fibers.

Abstract: A composite product (1, 2, 3, 4, 300) comprises a body (100, 200, 301) and a polymeric component (41, 50, 51, 55) cast onto a surface of the body. In one form, the product is for water infrastructure and the body is in the form of a hollow section and a water impermeable interface is formed between the body surface and the component.

Abstract: A flotation object floats on the surface of outdoor ponds and other bodies of water. The flotation object includes a circular middle portion and first and second hexagonal end portions. When the flotation objects are placed in a pond the objects contact each other in such a way that the flotation objects substantially interlock.

Abstract: A method of preparing a sterile article is disclosed. A polymer having a halogen-containing repeating unit is prepared that contains about 0.
