  • Patent number: 5362433
    Abstract: In a process for producing melt-spun elastomer threads with a high modulus, a breaking elongation of 80 to 300% and a boiling shrinkage of at least 20%, multifilament elastic threads are obtained by spin-drawing. A molten mass of polyurethane granulate is simultaneously drawn at a drawing factor of at least 1.5 and wound on spools at 600 m/min. or more. The spun-drawn, non-adhesive TPU thread can be processed to form a flat structure, the elasticity of which can be regulated by setting or by tempering in hot water. The thread can also be tempered before being processed in order to acquire the desired elastic properties.
