What impact does high humidity have on cotton fiber?

High humidity has a significant impact on cotton fiber, particularly contributing to increased fiber rot and diseases. When humidity levels are high, moisture can penetrate the cotton plants, creating a conducive environment for the growth of fungi and bacteria. This excess moisture not only promotes disease but can also lead to degradation of the fiber itself, resulting in lower quality and reduced market value.

Fungal infections, such as Alternaria and fungal leaf spots, thrive in high humidity, leading to diseases that affect the growth and quality of cotton plants. If these diseases are not managed effectively, they can compromise the overall health of the cotton crop, ultimately impacting fiber integrity and leading to inefficient harvesting and processing. Thus, high humidity is detrimental to cotton by facilitating conditions that promote fiber rot and disease, which negatively affect fiber quality.
