    摘要: The synthetic threads are produced from a polymer mixture consisting of polyamide, which serves as a base polymer, and of at least one additive polymer, whereby the polymer mixture, provided in the form of a polymer melt, is forced through nozzle openings with injection velocities (s) ranging from 18 to 160 m/min. The filaments formed in this manner are cooled, whereby they combine to form threads, which are then drawn off and wound while forming at least one thread spool. The content of additive polymer in the polymer mixture is a minimum of M wt. % and a maximum of 2.5 wt. %, whereby M results from 0.001 . v - 0.4, v being the draw-off velocity of the thread, whereby v ranges from 4,500 to 8,000 m/min. The additive polymer is amorphous and is practically insoluble in the polymer melt. When the thread is in a wounded state, the additive polymer in the base polymer exists with a fibril structure, and the ratio s: v ranges from 1: 50 to 1: 250. After winding, the thread spool preferably has a wound thread weight of at least 4 kg.

    摘要: The invention relates to an elongation-increasing agent which can be processed in an amorphous and thermoplastic manner, is made of radically polymerized, vinylic monomers, and is used for producing synthetic threads from a melt-spinnable fiber-forming matrix polymer that is incompatible with the elongation-increasing agent. The invention is characterized in that the elongation-increasing agent is thermally stabilized by adding an antioxidant substance such that said elongation-increasing agent is provided with a maximum total monomer content of 6 percent by weight after being thermally loaded at 290 °C for 30 minutes in an argon atmosphere. The invention further relates to granular plastic materials containing said elongation-increasing agent and a method for the production thereof. Also disclosed is a method for producing synthetic threads from a polymer mixture of a melt-spinnable, fiber-forming matrix polymer and an elongation-increasing agent in a melt-spinning process, and the subsequent use of said synthetic threads.
