Materials research. Materials engineers studying scanning electron micrographs (SEMs) of cotton fibres to discover the structure of white-speck neps,or areas of cotton that do not take up dye and appear as white flecks on dyed fabric. These flecks are undesirable and can ruin batches of cotton. They were found to be caused by underdeveloped fibres which lacked a secondary cell wall. This problem might be addressed by improving the growing conditions to allow the cotton to mature fully | |
