摘要： A thermally improved polyester weft yarn is provided by melt-spinning a blend of a polyethylene terephthalate polymer and a small amount of polymer having a glass transition temperature of at least 10.degree. C. higher than that of the polyethylene terephthalate polymer. The yarn has a break elongation of 70% to 200% and a dry heat shrinkage of +5% to -2%, and is capable of withstanding a severe heat-treatment, for example, at 245.degree. C. for 2 minutes during dipping and curing process of a tire cord fabric comprising the same. Even after such heat-treatment, the yarn shows a residual break elongation of more than 60%. Thus, the weft yarn extends uniformly, without breakage, to a toroidal shape during a tire building process, keeping warp cords at a equi-distance relation. A tire cord fabric comprising the weft yarn of the invention finds its use as the carcass in the form of single ply in a radial tire.

摘要： A method for drawing and heat-treating an undrawn polyester yarn by drawing the polyester yarn between a heated feed roller and at least one heated draw roller, wherein the surface temperature of the last draw roller is progressively raised from its yarn in-coming side to its yarn out-going side, the yarn is shrunken both on the last draw roller and between the last draw roller and the take-up roller, and the yarn is cooled on the take-up roller. Further, after the method has resumed after being stopped, the running speed of the yarn on the take-up roller is maintained at not more than (100-5.7.times.S)m/min., wherein S is the total shrinkage of the yarn until the yarn heated during the stoppage has been allowed to shrink in the subsequent step. The yarn is then passed over the take-up roller at a running speed of 200 to 1200 m/min. An apparatus for performing the above method, characterized by the provision of a shrinking part in the last draw roller, means for heating the surface temperature of the last draw roller progressively from its yarn in-coming side to its yarn out-going side and a groove on a separator roller associated to the penultimate draw roller for regulating the yarn path of the last turn of the yarn.

摘要： Textured polyester yarn is prepared from multifilament yarn composed of a synthetic linear ethylene terephthalate polyester by draw-texturing at a draw ratio of 1.05 - 1.30X, using a heat-setting temperature of about 170.degree. - 240.degree.. Feed yarn for said draw-texturing process has (a) a break elongation of 40 - 80%, (b) a density of above 1.371 g/cm.sup.3, and (c) a boil-off shrinkage of less than 8%. Said feed yarn is prepared by modified melt spinning of the foregoing polyester at a speed of about 3000 - 5000 meters per minute.
