- Results are reported of an investigation to determine the general processing per formance, in the cotton processing system, of cotton containing various percentages of fibers treated with dimethylol ethyleneurea, and the properties of the resultant yarns and fabrics. The resin-treated cotton was evaluated in 100% form and in blends with scoured cotton. Fabrics woven with filling yarns spun from the 100% treated cotton and the blends, using a common untreated warp, were evaluated for warmth properties in terms of thickness, bulk density, and air permeability. Difficulties were experienced in processing cotton with large percentages of resin- treated fibers due mainly to uneven drafting and the formation of static charges during the carding and drawing operations. Yarns spun from cotton containing resin-treated fibers were progressively weaker. less uniform, and more degraded in appearance as the percentage of resin-treated fibers was increased. Yarn elongation-at-break decreased with the addition of resin-treated fibers, but elongation at loads below the breaking point increased, indicating a relationship between yarn elongation at low loads and yarn bulk. Although experimental fabrics having improved warmth properties were made from yarns composed of 50% or more resin-treated fibers, it was concluded that, with present knowledge, the lower yarn quality and the poor processing performance would make production difficult on a commercial scale.
