Method for spinning and spooling of polyester - - multifilament yarns with the use of spinning additives, and also by the spinning - method available polyester - - multifilament yarns

摘要

The present invention relates to a process for the production and the winding up of preliminarily oriented polyester - - multifilament yarns, the at least 85 w -%, based on the total weight of the multifilament - yarn, from polybutylene terephthalate (pbt) and / or polytrimethylene terephthalate (ptmt) and between 0,05 w -% and 2,5 w -%, based on the total weight of the multifilament - yarn, of at least one additive - polymer contain, as a percentage of. In this case, the method characterized in that a long time bearing provides stable yarn winding packet which, during storage and transport is insensitive to elevated temperatures, by the yarn winding packet of the polyester - - multifilament yarn at a temperature in the range of 45 deg c. to 65 deg c during. Dollars a subject matter of the present invention by the process are, in addition, the polyesters obtainable - - multifilament yarns as well as their use.
