Button Pull Tester
The Button Pull Tester is designed to measure the attachment strength of buttons, snaps, and other fastening components on garments. It applies a controlled vertical pulling force to determine the force required to detach or sufficiently deform the attachment, helping manufacturers evaluate fastening reliability and reduce the risk of buttons or decorative components becoming detached during use.
The tester can be equipped with NK and HP series push-pull force gauges and dedicated fixtures. Its screw-driven mechanism, movable sample platform, and stable desktop structure provide convenient positioning and controlled force application for garment accessory testing.
Application
(1) Buttons on Garments
Evaluating the attachment strength of sewn buttons on shirts, jackets, trousers, children's clothing, and other apparel.
(2) Snap Fasteners
Testing the fastening strength of snaps and similar clothing accessories.
(3) Decorative Attachments
Evaluating decorative buttons and attached components that may become detached during normal use.
(4) Infant and Children's Clothing
Supporting safety evaluation of small attached components where accidental detachment may create a choking hazard.
(5) Garment Quality Control
Used for incoming inspection, production quality control, supplier evaluation, and product development.
(6) Button and Fastener Comparison
Comparing attachment performance among different button designs, sewing methods, materials, or suppliers.
Standards
(1) Button size > 6 mm: withstands a pulling force of 90 N
(2) Button size ≤ 6 mm: withstands a pulling force of 50 N
The applicable standard, test fixture, pulling method, and acceptance criteria should be confirmed according to the target market, garment category, and customer's required specification.

FAQ
(1) What is the purpose of a button pull test?
The test determines whether buttons, snaps, and attached decorative components have sufficient attachment strength. It is particularly important for children's garments because detached small components may present a choking hazard during normal use.
(2) What pull force should a button withstand?
According to the requirements provided, buttons larger than 6 mm should withstand 90 N, while buttons 6 mm or smaller should withstand 50 N. The applicable requirement should always be confirmed against the customer's specified standard or test method.
(3) Can this tester measure both buttons and snap fasteners?
Yes. The tester can be configured with dedicated fixtures for different fastening components. The appropriate fixture should be selected according to the button or snap design, attachment method, and required testing procedure.
(4) How should I choose the force gauge for this tester?
The tester can be equipped with NK and HP series push-pull force gauges. Selection should consider the required test force, measurement range, resolution, fixture configuration, and applicable test procedure rather than choosing a gauge based only on the maximum tester load.
(5) Can QINSUN recommend a suitable button pull testing configuration?
Yes. QINSUN engineers can review your button type, size, attachment method, required force, applicable market standard, and testing frequency to recommend a suitable gauge and fixture. QINSUN calibrates and functionally tests equipment before shipment.
