What issue is associated with Haitian cotton due to foreign material?

The browning of Haitian cotton due to foreign material is a result of the natural fibers absorbing impurities and contaminants present during the harvesting, processing, or storage phases. This browning can occur when there is moisture present along with sugars or other organic materials that lead to a chemical reaction, causing discoloration.

In the case of Haitian cotton, which is often harvested in less controlled environments, it's particularly susceptible to such issues. Foreign materials such as dirt, leaves, and other organic matter can lead to aeration problems and promote a condition known as blooming, resulting in unsightly brown patches or overall discoloration. This browning is not merely a cosmetic issue; it can impact the fabric’s perceived quality and overall value.

By understanding this phenomenon, one can better address preservation and cleaning techniques to maintain the integrity and appearance of Haitian cotton products.
