Cotton fibers are generally wet than dry

Cotton fibers are generally stronger wet than dry.
The increase in strength is due to the better load distribution between the fibers. The water binds the fibers, which results in increased attractive forces, preventing the fibers from slipping over one another; therefore, the strength of the material is increased.
