Researchers tracked neps throughout wool processing, spinning, and weaving to determine the relationship between neps counted in the top and the appearance of the final fabric. Part of the study determined the effects of comb input loading and speed on the generation of fiber faults from recombing through to finished yarns. Data showed that during processing from single combed top to roving, the total nep population tended to increase, even though recombing markedly reduced nep counts. Nep counts in the drafted roving gathered on the exit rolls of the spinning machine showed a decrease in the number of neps. The twofold yarns showed a reduction in the number of neps. The recombed finished fabrics showed two neps per 10 running meters. Although the frequency of neps counted in the tops was proportional to that detected in the final fabric, the neps appeared to have little impact on fabric quality or appearance.
