Nigeria has been known to produce raw cotton in the past. Is Cotton still grown in large quantities in Nigeria? If so, are there cotton farms from which cotton can be purchased directly?
Not sure about the presence or location of cotton farms. You may have to find a cotton aggregator to get the answer to that exact question. Here is a link from the raw materia research and development council of Nigeria. It contains information of the states where you can find raw cotton. Hope that helps.
