ABSTRACT OF DISCLOSURE A method of producing twine composed of a plurality of thermoplastic monofilaments in a bundle which comprises, passing a bundle of thermoplastic monofilaments continuously along a path, imparting a false twist of 3 to 30 turns per linear foot to said bundle, applying a compatible molten thermoplastic spiral. In addition to high tenacity, the present invention imparts reduced shrinkage and elongation to monofilament fibers, facilitating the use of. Most 3D. Arnitel belongs to the TPE subcategory of thermoplastic copolyesters (TPC). . S. Phone: +49 8638 9810-479. For closed 3-D knitted composites, it is the aim to impregnate the skins and most of the time also the core. U. Polymers 2021, 13, 590 3 of 12 The soft segments have a glass transition point, which is below the usage temperature so that the molecules can be shifted flexibly due to low intermolecular interactions. A thermoplastic filament comprising multiple polymers of differing flow temperatures in a regular geometric arrangement, and a method for producing such a filament, are described. 0X. e.
