Industrial yarn PA 6.6 comprised of filaments having a global yarn count of at least 900-2100 tex, which is made by submitting wet granulate PA 6.6 to a melt spinning-drawing process, is characterized by a strength of >84 cN/tex for less than 1.5 linters/1 km. Said yarn is used preferably in the production of cord fabric with a rubber ply.

The friction texturized polyester filament yarn has a titer of 400 to 600 dtex and a crimpability of at least 45% and can be provided with at least 60 slubs/m. The method of making this friction texturized polyester filament yarn comprises texturizing a flat yarn with a titer of 400 to 600 dtex at a rate of at least 350 m/min and a yarn tension ratio, F2/F1, less than one via a squeezing twister. A set yarn can be made from the friction texturized polyester yarn with the titer of 400 to 600 dtex by heating.

A process of high-speed spinning of a set of thermoplastic monofilaments having a linear density from 1 to 30 dtex, includes spinning to obtain melt-spun thermoplastic monofilaments and airblast cooling of the melt-spun monofilaments. To produce a particularly fine monofilament at high winding speeds, the process also includes guiding the thermoplastic monofilaments directly over a fork-like friction element having axially parallel, spaced apart upper and lower contacting friction surfaces during the airblast cooling, and then spin finishing and winding up the thermoplastic monofilaments. An apparatus for melt-spinning including the friction element is described. The product monofilament produced by the process can have an elongation of 20 to 45%, a strength of 36 to 60 cN/tex; a boil shrinkage of 2 to 15%; an Uster % less than 1 and a uniformly round cross section.
