Abstract

The present invention belongs to the field of textiles and specifically discloses a moisture-conducting, quick-drying knitted multi-layer fabric and its weaving method. Two or more of five structures, including large loops, small loops, regular loops, tucked loops, and floating threads, are selected to form a fabric with multiple layers of varying pore densities. Liquid can be rapidly conducted outward from the interior of the fabric through the pores of the multi-layer structure and rapidly diffuse through the outer layers, achieving a permanent and efficient moisture-conducting, quick-drying effect. Testing has shown that the quick-drying fabric disclosed in the present invention has a wicking height of approximately 200 mm, exceeding the industry standard of 100 mm, and an evaporation rate of over 0.48 g / h, far exceeding the national standard of 0.18 g / h.
