Description

technical field [0001] The invention relates to the technical field of fabric detection, in particular to a detection device and method for a fabric friction coefficient. Background technique [0002] As one of the effective means to prevent and treat varicose veins, medical compression stockings have been widely accepted by vascular surgery experts and patients at home and abroad, and the products have been used clinically. While medical compression stockings satisfy their therapeutic effects, there are also some problems in practical application. Difficulty in wearing and leg discomfort after long-term wearing are two common problems at present. [0003] Difficult to wear The specific manifestation is that the narrower compression stockings are passed through the relatively wide legs (such as the ankle joint) with both hands. The pressure exerted by the compression stockings on the legs leads to greater frictional resistance, making it extremely difficult to put on , espe...
