A method for evaluating crease recovery of fabrics based on power function equation. The steps are: (1) place the sample in the sample placement area; (2) pressure the overlapping part of the sample; (3) let the free part of the sample automatically restore and record the video image of the sample crease recovery by camera; (4) process the video image of the fabric crease recovery and calculating the recovery angle of each frame of video image; (5) repeat steps 1 to 4 to measure N samples of the same fabric; (6) obtain the dynamic process of fabric crease recovery angle change. This can reveal which type of fabric has better recovery property, when the existing methods have the similar results of recovery angle.

A method measures inside a blanket of mineral and/or plant fibres being moved by at least one conveyor with a conveyor belt. The method uses a measuring system including a sensor and an actuator for introducing the sensor into the blanket, the actuator being mounted on the conveyor belt and able to move the sensor between a retracted position and a measuring position inside the blanket. The method also includes introducing the sensor into the blanket by the actuator under the effect of the movement of the conveyor belt.

A fabric automatic precise folding device has a rotating mechanism, an automatic folding mechanism and a crease generating mechanism. The automatic folding mechanism is located below the finger cylinder on one side of the rotating mechanism, and the finger cylinder on the other side of the automatic folding mechanism is fixed with a crease generating mechanism. The two rotating cylinders are central symmetrical with the rotating arm. This accurately controls the bending and folding of the fabric sample through the automatic control technology, and realizes the automatic detection of the fabric crease recovery process. By mechanical and numerical control technology, the parts to be measured are effectively prevented from interference by human factors, and the detection accuracy is improved.

Provided are a method and device for detecting arrangement disorder of fibers in a conductive composite material. A coil (7) is disposed at a position at which the coil (7) faces the conductive composite material, and thereby a current can be applied to the conductive composite material. Thus, work or the like for attaching electrodes to the conductive composite material is not required. As a result, the arrangement disorder of the fibers in the conductive composite material can easily be detected.
