Research on the Seamless Knitted Fabric Comfortability of Coffee Carbon and Graphene Far-Infrared Polyamide Fibers

In order to explore the comfortability of far-infrared seamless knitted fabric, this study chose coffee carbon polyamide fiber and graphene polyamide fiber as the face yarn materials to design this experiment. Both face yarn ratio and stitch were experimental factors. According to comprehensive factorials, we weaved 12 samples and tested the warmth, hygroscopicity, moisture vapor transmission and permeability of the fabric. The properties: warmth, hygroscopicity, moisture vapor transmission and permeability were influenced by face yarn ratio and stitch, and the relationship among them was studied by the fuzzy comprehensive evaluation method. The research showed that: factor A, the face yarn ratio has the greatest effect on hygroscopicity. When the face yarn ratio of the fabric is 25:75 with plain plating stitch, fabric hygroscopicity is predominant. And factor B has the greatest influence on moisture vapor transmission and permeability of the fabric. When the face yarn ratio is 25:75, and the stitch is 1+1 false rib, moisture vapor transmission is excellent. When the face yarn ratio is 25:75, and the stitch is 1+3 rib, fabric has the warmest and the most permeable properties.
