A Study Of Cotton Blending

Twenty-nine different blends involving two-bale mixes of two varieties of cotton—namely, (1) Hi- Bred, ranging in staple from 13/16 to 15/16 inch, and (2) Bobshaw No. 1, ranging in staple from 11/16 to 13/ 16 inches—both varieties represented in grades "middling white" to "strict good ordinary white," were studied. The effects of various combinations of these grades and staples on spinnability, yarn skein strength, yarn appearance, and manufacturing waste were noted. In general, the deleterious ef fects of off-grade were offset by an increase in staple length of the low-grade type in spinning coarse-to- medium counts. It was indicated that a consider able economic advantage was obtainable through the strategic blending of various grades and staples of cotton over a range considerably wider than that generally considered practical in the industry.
