How to use the button tension tester？

The button tension tester can be equipped with NK, HP series push-pull force gauges, and special fixtures, which are specially used to measure the fastening force of buttons or the destructive force of buttons from clothing. Testing the fixing strength of buttons and buttons is an important standard, especially in the design and manufacture of infant and children's clothing.

Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. was established in 2012. It focuses on the research and development, design, and production of textile testing instruments, and provides textile testing instruments and services for academic research units and testing institutions. Shanghai Qianshi is currently one of the most competitive R&D textile testing instrument manufacturers in China. The R&D team is composed of a group of experienced engineers. We are committed to serving customers wholeheartedly and striving to promote the technological innovation of textile testing instruments.

Meeting standards:

CFR1500.51-53, ASTMPS79-96, GB6675, ISO8124

Test principle:

By rotating the upper speed regulating wheel, the user can apply a fixed force and record the fixed force or braking force. Using clamps and accessories, other buttons, denim buttons, four-hole buttons and clothing accessories such as zippers, bow ties, appliques, hooks, D-rings, etc. can also be tested.

Operation:

1. Install the clamp, match the buttons to be tested, and lock the test sample to the base

2. Put down the clamp, grab the buttons, and pull them up. Each set of buttons must be able to withstand a tensile force of 17 pounds, i.e. 7.72kg, and must be maintained for 10 seconds without signs of loosening or damage. 20 buttons of each type must be tested at the same time to be qualified

3. If one of the buttons is loose or damaged, or after replacement, all must be retested

Significance and function:

1. The test method of this instrument is used to measure the strength of the vertical tensile test on buttons and clothing, and the buttons and buttons are not pulled off the clothing.

2. The button sewing specifications required by this method should be in accordance with the standards set by the button manufacturer.

3. This test method is used to establish the relevance of different wearing environments and to compare different types and brands of buttons.

4. This standard may include hazardous materials, operations, and instruments, and the standard does not list all possible safety issues that may arise during use. Therefore, it is the responsibility of the user of this standard to establish relevant safety and health rules and determine appropriate regulations before use.

5. All buttons need to be sewn tightly to the fabric with a chain stitch.

6. According to the test requirements, when the largest button size is greater than 6mm or less than/equal to 6mm, the button must be able to withstand a tensile force of 90N and 50N respectively.
