Principle of button pull tester and testing steps

Author:QINSUN Released in:2023-10 Click:102

The Button pull tester is an instrument used to test the fastening or fastening strength of buttons and buttons to ensure that buttons, buttons and fasteners can be properly fixed on clothing and prevent buttons from coming off clothing. This creates a choking hazard for infants.

1. Principle of button pull tester

The upper clamp and lower clamp of the button pull tester tighten the garment components. The gripper moves at a set speed until the part falls. Record the intensity and pattern of excretion. You can choose the appropriate pliers according to the different buttons

2. Button Pull Tester Testing Steps

1. Tightening separation rate

Set a certain blessing separation rate according to relevant standards. For example, the exigence of GB/T 22704-2008 is (100 ± 10) mm/min.

2. Start the tensile tester and place the sample

Adjust the position of the fixture to keep the center axis of the upper and lower fixtures and the uniform tension direction . Consistent Place the sample in the center of the clamp, ensuring that the longitudinal centerline of the sample passes vertically through the centerline of the upper and lower clamps. When placing the sample, make sure there is no damage or slippage.

3. How the Button Pull Tester Works

Use the button pull tester to record the maximum pull force. The upper clip pulls the piece until it separates from the garment or breaks. The main methods of damage are component damage, attachment method damage, and fabric damage.

4. Recording ofhe test results

Record the maximum tensile force of each sample, in Newtons, at 0.1N.
