Tow that is suitable for processing on a worsted or woollen system consists essentially of continuous polyester filaments that are a mixture of filaments of higher denier and of lower denier and that have a scalloped-oval or other cross-section that is of generally oval shape, but with grooves or channels that run along the length of the filaments. Such polyester tows provide improved processing on the worsted system to provide spun yarns of polyester and blends with wool, and downstream articles, such as fabrics and garments. |
