Abstract: 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.

Abstract: A method is described which comprises a method for the production of a monofilament from a mixture of a melt-spinnable, filament-forming polymer and a modifying additional polymer, characterised in that a mixture of one or more melt-spinnable, filament-forming polymers and 0.001 to 10% by weight of a perfluorinated polyether is spun to form monofilaments. The monofilaments are particularly well suited for woven fabrics which are used in paper machine clothings, conveyor belts, filtration screens and screens for silkscreen printing.
