Polyester 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.

DETAILED DESCRIPTION OF THE POLYESTER TOW

Polyester filament tows that are suitable for processing on the worsted or woollen systems. Presently, such tows as are available commercially are believed to have been bundles of crimped, drawn continuous filaments of round filament cross-section and of denier generally about 900,000, each filament being of about 3 denier. Denier is the weight in grams of 9000 meters of fiber and thus a measure in effect of the thickness of the fiber. When one refers to denier, the nominal or average denier is often intended, since there is inevitably variation along-end and end-to-end, i.e., along a filament length and between different filaments, respectively. In general, it has been the objective of fiber producers to achieve as much uniformity as possible in all processing steps along-end and end-to-end so as to produce a polyester fiber of round cross-section and of a single denier and of as uniform denier as practical. This is present commercial practice in producing tows for processing on the worsted system. In contrast, my invention provides polyester tows of mixed dpf, using filaments of different (non-round) cross-section, and uses chain-branched polymer.
