Device and method for measuring hairiness and hair ball state and pulling-off force of fabric

The invention relates to a device and method for measuring the hairiness and hair ball state and pulling-off force of fabric. The device is composed of a cloth sample barrel of rolled fabric, a rotating mechanism driving the cloth sample barrel, a friction mechanism enabling a cloth sample to be in a pilling state, a pulling-off mechanism clamping and pulling hairiness and hair balls off, an optical measuring system used for observing the hairiness and ball top state of the cloth sample, a collecting and weighing mechanism used for collecting and weighing falling fiber and ball tops, a data collection and control system and a computer. The method comprises the steps of measuring the height and the amount of the hairiness and the size and the number of the ball tops after the cloth sample is packaged in a rolling mode with the same tension, sampling through rubbing to enabling the cloth sample to be in the pilling state, and measuring the amount of the hairiness of a friction sample which is in process and is
