Abstract:

In order to develop a three-dimensional knitted fabric with excellent dynamic humidity and temperature control, 70 dtex(72 f)×2 DRYARN® and 30 dtex DRYARN® wrapped with a 30 dtex spandex filament were selected as raw materials. The topological optimization design method of three-dimensional knitted fabrics was proposed, where the temperature control units were optimized to be arranged in V-shape, Y-shape and other dislocated arrangement, and a folded sheet structure was created by locally stretching and pleating the fabric by using the single-sided jacquard process. The result show that when the human body is sweating, the inner layer of the folded sheet structure absorbs sweat drops and transfers the moisture to the surface layer for rapid evaporation. When the human body feels cold, the inner air channel stores still air and effectively controls the temperature. The insulation rate of the prepared fabrics is more than 54%, and it has excellent temperature control performance. The overall liquid water transfer capacity is more than grade 3, and the liquid water dynamic transfer performance is good, while maintaining excellent tensile recovery performance. It provides a new idea for the research and development of three-dimensional knitted fabrics for winter thermal sports underwear.

Key words: functional knifted fabric, humidity and temperature control, 3-D knitted fabrics, topological geometry
