Conclusion

Cotton is under constant threat from artificial fibres, and presence of contamination is one of its main weaknesses. If this not controlled at the origin, it will have a serious impact on the whole cotton industry in the long run. Spinners might prefer to spin artificial fibre yarns and blends, rather than investing in expensive electronic equipment and still running a high risk in spinning cotton and its blends. It is high time for cotton growers, ginners and supporting organizations to get together and act on this issue, especially to minimize fibrous contaminants such as polypropylene, coloured threads, coloured cloth pieces and hair.
