Technical Abstract: This paper reviews pertinent information related to moisture management in cotton. Maintaining proper moisture content is critical to maintaining fiber quality in all phases of cotton production, processing and utilization. Fiber length during ginning is directly related to moisture, increases in moisture improves fiber length inches and reduces short fiber content. Drying is also very important both from an exposure temperature and moisture standpoint. Temperatures over 200°F increase fiber damage, especially as the temperatures approach 350°F. Moisture contents below 5% are especially damaging to cotton fiber. Restoring moisture to cotton before fiber-seed separation yields positive results in fiber quality. Adding moisture after fiber-seed separation increases bale weight and reduces bale packaging forces. Spraying water droplets directly on fiber as it flows down the lint slide into the press box must be done with moderation to avoid weight loss and color degradation during storage. Moisture contents above 7.5% are not recommended for bale storage. Gin managers must ensure that cotton fiber is dried only as necessary to achieve the desired leaf grade. Moisture management (drying and restoration) systems must be properly calibrated and maintained, and moisture contents measured accurately. Proper management of moisture will assure quality cotton.
