In this paper, the effect of coffee carbon and graphene far-infrared polyamide knitted fabrics on blood perfusion were studied based on the test method of human skin microcirculation (HSM), starting from the plating yarn feeding ratio and stitch of seamless knitted fabrics. Set the face yarn feeding ratios of coffee carbon polyamide (CCP) and graphene polyamide (GP) as 100:0, 75:25, 50:50, and 25:75. The stitches were 1 + 3 rib, 1 + 1 false rib, and plain plating. Both the plating yarn feeding ratio and stitch were designed as two experimental factors. According to the comprehensive experimental design method, 12 seamless knitted fabrics were prepared. The HSM was tested by BVI Projection Vein Finder. According to the orthogonal analysis method: Factor A, the plating yarn feeding ratio has the greatest effect on HSM, the second was factor B. When the plating yarn feeding ratio was 75:25, the stitch was 1 + 3 rib, the fabric has an excellent promoting effect on HSM. The purpose of this study was to explore the process parameters of far-infrared seamless knitted fabrics that have a better promotion effect on HSM, to apply the process to develop functional health care clothing to meet people’s market needs.

本文以人体皮肤微循环试验方法为基础，研究了咖啡碳和石墨烯远红外聚酰胺针织物对血液灌注的影响，从无缝针织物的镀层喂纱率和缝制角度入手。将咖啡碳聚酰胺（CCP）和石墨烯聚酰胺（GP）的面纱进给比设置为100：0、75：25、50：50和25:75。针脚为1 + 3肋，1 + 1假肋和平纹。电镀丝的进给比和线迹都被设计为两个实验因素。根据综合实验设计方法，制备了12种无缝针织面料。HSM由BVI Projection Vein Finder测试。根据正交分析方法：因子A，镀层喂纱比对HSM影响最大，其次是因子B。电镀丝进给比为75:25时，针迹为1 + 3罗纹，该织物对HSM具有优异的促进作用。这项研究的目的是探索对HSM有更好的促进作用的远红外无缝针织面料的工艺参数，以应用该工艺开发功能性保健服以满足人们的市场需求。
