EVOLUTION OF SMART FIBERS: A REVOLUTION FROM MICROSCOPIC CURLING TO MACROSCOPIC WARMTH RETENTION
After high-temperature wet processing, the thermal storage hollow Sorona forms a curled structure due to significant shrinkage diferences, significantly enhancing its elasticity. In terms of insulation technology, the principle of simulating the vacuum layer of thermos can effectively block the human bodylleat is conducted toprovides feedback, increases skin temperature, achieves efficient heat storage and insulation, and brings a dual enjoyment of technology and comfort to fabrics.
