Hollow nylon, as an innovative textile material, boasts outstanding thermal conductivity (approximately four times that of cotton), effectively facilitating the rapid dissipation of body heat and achieving a natural cooling effect. Its unique feature lies in the use of an irregularized spinneret technology for spinning, which gives the fibers a hollow structure. This ingenious design effectively reduces the direct impact of solar radiation on the perceived body temperature, effectively blocking the transfer of external heat to the human body, providing wearers with a significant cooling sensation and insulation experience. It is an ideal fabric choice for summer clothing and outdoor protection.
