    摘要： Methods of continuously producing sequential lengths of different additive-containing melt-spun filaments include continuously supplying a melt-spinnable polymeric host material to orifices of a spinneret and controllably dosing at least one dispersible additive concentrate system containing a pigment in a liquid nonaqueous polymeric carrier to the melt flow of polymeric host material upstream of the spinneret orifices. In such a manner, a first polymeric mixture of the dispersible additive concentrate system and the polymeric host material is obtained which achieves an additive attribute. During a first time interval, the first mixture is extruded through the spinneret orifices; and thereafter, during a second subsequent time interval, the dosing of the at least one dispersible additive is changed so as to form a second mixture having a second additive attribute different from the first additive attribute while continuously supplying the melt flow of polymeric host material to the spinneret orifices. The melt-spun filaments will thus have a first length corresponding to the first additive attribute of the first mixture and a second subsequent length corresponding to the second additive attribute of the second mixture. The methods and additives employed most preferably achieve Hunter Green Purge Values of between about 0.10 to about 1.40 sec/cm.sup.3.

    摘要： A yarn comprising polyester fibers having an improved balance of properties (tenacity and boiling water shrinkage) is produced within predetermined limits. The polyester yarn is prepared by cold drawing a partially oriented feeder yarn, partially annealing the drawn yarn, and subsequently annealing the partially annealed cold drawn yarn at controlled tensions.
