Seed-coat fragments in ginned lint cotton have been identified as a problem during mill processing by the textile industry. They are considered a major cause of ends down during spinning and appear as imperfections in dyed fabric. This paper reports on an investigation where bales arriving at a U.S. mill from gin or compress sources in five cotton-producing states were sampled for seed-coat fragment levels. Cotton-seed particles in the bales were classified as fragments, motes, and funiculi; measurements were obtained using both the count and weight procedures; and fragments were arrayed according to physical size.
