  • Process for making stable polytrimethylene terephthalate packages
    Patent number: 7022273
    Abstract: A process for the production and for the winding of one polyester yarn, preferably multi-filament yarn, which comprises at least about 85 weight %, in relation to the total weight of the polyester yarn, of polytrimethylene terephthalate (PTT) wherein said process is characterized in that filaments of said polyester yarn is heat-treated, before it is wound on a bobbin, at a temperature in the range of about 70° C. to about 180° C. The method of accomplishing this is by heating the godets that are used in the spinning part of the process, preferably the last pair of godets, to relax the yarns so that the yarn package will not shrink significantly during storage and/or transportation. It is thus possible to obtain at least one PTT yarn package with long-term stability during storage and which is insensitive against elevated temperatures during storage and transport.
