Nonwoven thickness gauge experiment operation method

I. Purpose

1、Familiar with the working principle of the fabric thickness meter.

2、Familiar with the operation method of the fabric thickness meter.

Second, the instrument and utensils

Nonwoven thickness gauge and its accessories.

Three, the specimen

Nonwoven fabric.

Fourth, the working principle of the instrument

The specimen is placed on the standard plate, parallel to the pressure foot of the plate, the prescribed pressure is applied to the area of the specimen specified, and the vertical distance between the two plates is recorded within the specified time, that is, the thickness of the fabric.

V. Precautions

1、When replacing the presser foot or during a long period of time without using the instrument, please protect the rubber pad placed between the presser foot and the reference plate to protect the measuring surface from damage.

2, after each experiment should be turned off the power switch, and the instrument's power plug out of the power outlet.

3、The battery should be removed when the instrument is not used for a long time to avoid leakage of liquid.

Sixth, thinking questions

1、What are the factors affecting the thickness test results?

2、What are the reasons for the large difference between the coefficient of variation values of the measurement results of nonwoven and woven and knitted fabrics?

Seven, experimental report requirements

Record the experimental data in detail and analyze it.
