In a yarn, moisture content is the moisture present in the yarn, expressed as a percentage of the total weight of the yarn. Moisture content is one of the most important tests on a yarn; [9] a fiber's moisture content will affect the entire manufacturing process, as it affects the physical properties of a material.
Water is a better conductor of heat than air, thus if clothes are damp — because of sweat, rain, or immersion — water replaces some or all of the air between the fibres of the clothing, causing thermal loss through conduction and/or evaporation. Thermal insulation is thus optimal with three layers of clothing:
