Abstract A composite yarn of two discrete classes of filaments, each class having a different dye affinity or dissimilar inherent apparent coloration is characterized by a degree of filament intermingling of at least 65 percent, a break elongation from 5 to 100 percent, the difference in percent break elongation between the discrete classes of filaments being less than 15, and a tenacity from 1.0 to 10 gpd. The yarn is produced by separately spinning or cospinning two synthetic fiber-forming polymeric compositions into a multiplicity of discrete filaments, combining the filaments into a composite yarn during or prior to drawing the filaments as an integral yarn, and further processing the yarn to yield the desired properties.
A Composite textile yarn comprising a multiplicity of continuous, oriented, synthetic, organic polymeric filaments of two discrete classes, one class comprising poly(hexamethylene adipanide) filaments and a second class comprising poly(ethylene terephtalate/(5-sodium sulfo)isophthalate) filaments, each of said classes of filaments having a dissimilar inherent apparent coloration, the said yarn having a degree of filament intermingling of at least 65 percent, the difference in percent break elongation of the filaments of the said discrete classes not exceeding 15, the proportion of one of said discrete classes being in the range of from 10 to 90 percent by weight.
