ABSTRACT:
An improved high performance polyester (at least 85 mol percent polyethylene terephthalate) multifilament yarn possessing a novel internal structure is provided. The multifilament yarn of the present invention possesses a high strength (at least 7.5 grams per denier) and an unusually stable internal structure which renders it particularly suited for use in industrial applications at elevated temperatures. As described in detail hereafter the subject multifilamentary material exhibits unusually low shrinkage and hysteresis characteristics (i.e. work loss characteristics) coupled with the high strength characteristics normally associated with polyester industrial yarns. Accordingly, when utilized in the formation of a tire cord and embedded in a rubber matrix, a highly stable tire may be formed which exhibits a significantly lesser heat generation uon flexing.
