Button physical performance test

September 18, 2018 BY TRIMS CO.,LIMITED Buttons Knowledge

The physical properties of the button can be determined in various ways depending on the type and structure of the product. Jean Button Rivet, Round Polyester Button, Alloy Jeans Button, Polyester Coat Button, Plastic Printing Buttons and other buttons, its basic performance mainly includes the measurement of tension, tightening, loosening, firmness, breaking strength and so on.

The physical performance test of the button is of great significance. Only those buttons that pass the test can be used. Poor quality buttons are likely to affect the use of clothing. All buttons used in garments should be tested for tensile strength to ensure that they can be securely fastened without accidentally falling off. Buttons used in infant and toddler clothing may be swallowed by babies if they accidentally fall. This is very dangerous, so more attention should be paid to the detection of buttons.

The measurement of pull strength is a critical testing procedure in the design and manufacturing of garments in the textile world. It refers to the maximum strength that clothing buttons could withstand when they are subjected to the tensile force applied, which could result in certain degree of deformation at the place where the buttons come into contact with the fabric or lead to the detachment of the buttons from the fabric.

The testing method and procedures may vary from one standard to another. And different fixtures are used based on the type of buttons, ranging from eyelets, rivets/studs, snap fasteners, snap buttons to prong snap buttons.

Regardless of the testing standard or testing organization, the pull strength of buttons attached to the garments can be measured in terms of N/KG(1KG=9.8N). As per AATCC (American Association of Textile Chemists and Colorists), the buttons subjected to testing should withstand a minimum pull force of 7.72KG and stay secured and intact without unfastening, breakage or damage for 10s. Generally speaking, buttons intended for the child wear should withstand a minimum pull of 90N, while button products designed for the adult clothing should withstand a minimum pull of 70N.

BY TRIMS CO.,LIMITED implement very strict quality control procedures. we carry out inspections into the Apparel Button products that require strong pull strength on a regular basis to ensure that they fulfill the requirements as stipulated.
