In order to improve the comfort,functionality,and aesthetics of pure aramid 1313 fiber fabric,pure and blended yarns composed of aramid 1313 fibers,flame retardant viscose fiber,and antistatic fibers as raw materials,and plain weave,2/2 twill weave and 3/3 twill weave as the basic structure for warp joining and interchangeable double layers product,six samples are developed through the design of surface and inner warp yarn arrangement.The flame retardancy,breathability,moisture permeability,and thermal insulation of each sample are tested.The results show that adding flame-retardant viscose fibers can improve the comfort of the product.The comfort of double-layer fabrics with a 3/3 twill weave as the basic structure is better than other double-layer products,and interchangeable grid fabric with plain weave is better than diamond and vertical stripe fabrics.
