▎ 摘　　要

NOVELTY - Humidity-sensing fiber comprises a humidity-sensing layer and conductive filaments arranged in the humidity-sensing layer. The humidity-sensing layer comprises a polymer and a humidity sensitive material distributed in the polymer. USE - Humidity-sensing fiber. ADVANTAGE - The distribution of different concentrations of humidity-sensitive materials in the fibers can be accurately controlled. The softness of the fabric can be achieved, and the water-washability and durability can be combined to meet the needs of wearable devices. The temperature-sensing fiber can be realized with the function of resisting temperature interference. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a humidity-sensing fiber, which involves performing co-extrusion process, a melt spinning process, a wet spinning process, or a thermal softening drawing process.
