Curtains often look dry on the surface but still contain moisture inside the layers.

• Thick fabrics like blackout or velvet trap water inside inner fibers
• Sun drying may dry the outer layer but not the inner folds
• Indoor drying with poor airflow slows evaporation significantly
• Folded or layered curtains retain damp pockets of moisture
• Lingering moisture produces a musty or damp smell over time

In Malaysia’s humid weather, this problem becomes worse because the air itself already contains high moisture levels, making complete drying more difficult.
