Background
At present, the thickness of the sound absorption cotton material is tested by using a digital display thickness gauge tool. Before testing, the height of the thickness gauge is adjusted to enable the presser foot to be completely attached to a horizontal plane below the presser foot, data is cleared, and the point is set as a zero point. And then lifting the presser foot, placing the sample piece to be measured on a horizontal plane, putting down the presser foot, falling on the central point of the sample to be measured, contacting for 10s, recording the reading, and then replacing the next sample. After all samples were tested, the thickness average was calculated.
