  • Method for spinning and reeling polyester multifilament yarns by using spinning additives, and polyester multifilament yarns obtained by said spinning method
    Publication number: 20050269439
    Abstract: The present invention relates to a process for producing and winding partially oriented polyester multifilament yarns not less than 85% by weight based on the total weight of the multifilament yarn polybutylene terephthalate (PBT) and/or polytrimethylene terephthalate (PTMT) that contain between 0.05% by weight and 2.5% by weight based on the total weight of the multifilament yarn of at least one additive polymer extensibility enhancer, which comprises providing a wound yarn package which is stable in long-term storage and insensitive to elevated temperatures during storage and transportation by heat-treating the wound polyester multifilament yarn package at a temperature in the range from >45° C. to 65° C. The present invention further relates to the polyester multifilament yarns obtainable by the process and to their use.
