Fabric density is one of the important factors affecting the moisture wicking and warmth retention properties of
sports socks, and its selection is crucial when designing and manufacturing sports socks. Fabric density refers to the number of yarns per inch or square centimeter in a fabric, usually expressed in threads per inch (SPI) or threads per square centimeter (CPI). In the manufacturing process of sports socks, different effects can be achieved by using fabrics of different densities, so the choice of fabric density is an important consideration for designers and manufacturers.
Generally speaking, lower density fabrics tend to provide better ventilation. This fabric allows air to circulate more easily and helps sweat evaporate, keeping feet dry and comfortable. Especially during high-intensity exercise, feet tend to sweat a lot. If the fabric density of sports socks is too high, it will restrict air circulation, causing sweat to stay inside the socks, increasing the feeling of moisture, and easily causing discomfort and blisters. question. Therefore, for such activities, sports socks with lower density are usually chosen to ensure good ventilation, reduce sweat accumulation, and improve comfort and wearing experience.
High-density fabrics generally have better thermal insulation properties. Keeping your feet warm is especially important in cold weather or during sports that require prolonged exposure to low temperatures. High-density fabrics can more effectively block the entry of cold outside air and provide better thermal insulation. This is especially critical for athletes in outdoor activities or high-altitude environments. It can effectively prevent feet from getting cold and improve physical fitness and endurance. Therefore, in these cases, choosing sports socks with a higher density is a more appropriate choice.
