Cool-feeling nylon yarn is a functional Nylon yarn with high-performance of moisture management. Due to the specially designed “cross” section, it takes advantage of its high superficial measure of area and grooves. Based on a siphon theory, it is easier to move perspiration away from the body. In addition, it has more space between the filaments than the regular yarns, therefore it can rapidly wick sweat, keep your skin dry and comfortable.
Due to the special addition of functional powder, it improves its cooling effect. Its thermal conductivity is far more superior to that of normal yarn and fabric. This double effect of“thermal conductivity plus hydration“ is exactly what we need in summer.
The base materials of cool-feeling nylon yarns are mesoporous materials full of numerous nano-sized micro-pores. At first, phase changes materials (PCMs) are dispersed and file into the micro-pores of the base materials. Then, materials with high specific heat are added to and mixed with the base materials to produce the cooling fiber. In this way, when human body heat is transmitted to the fiber, the PCMs on fiber surface can absorb water-vapor and carry away the body heat while the high-specific-heat materials can prevent heat transmission and avoid body heat from rapidly getting into the fiber. Therefore, the function of cooling nylon yarns are permanent.
Cool-feeling nylon yarns has been mainly used in clothes industry, such as summer underwear, T-shirts, sport wears, socks, biking gloves, hats, stockings, linings, and so on. It has been also used in other industry.
The continuous improvement in cooling materials has enabled to produce cooling chips during the process of polymerization. Subsequent spinning process is thus significant eased, which facilitates the commercialization of functional nylon yarns products.
