The invention discloses a fabric friction coefficient detection device and method. The detection device comprises a force measuring plate and a friction coefficient output unit. The surface of the force measuring plate is used for fixing a fabric, and when a friction object moves on the surface of the fabric in a preset mode, the force measuring plate is further used for obtaining the friction force signal and the pressure signal of the fabric and the friction object; and the friction coefficient output unit is used for obtaining and outputting a friction coefficient according to the frictionsignal and the pressure signal. Friction performance detection of the fabric is achieved, the real wearing state of a human body can be simulated, the real feeling of a user is reflected accordingly,a detection result is more accurate, and the use comfort performance of the fabric, especially medical pressure socks, can be evaluated more effectively.
