ABSTRACT:
Crimped polyamide staple filament mixtures and yarn therefrom having a high bulk, high luster free from objectionable sparkle and glitter, and improved resistance to soiling are produced. The novel yarn is a blend of trilobal polyamide filaments having different cross-sections, i.e., modification ratios, within specified ranges and specified proportions for each cross-sectional type of filament. This yarn has particular utility as carpet yarn. The method for producing the novel yarn comprises blending the above-described mixed cross-section filaments.
