Peel tests are used to determine the bond strength of bonded, fused, or laminated textile materials. Often the bonds tested are between textile and non-textile materials, such as the bond between the fabric plies and rubber used in tires or the adhesive bond between the backing material and pile of carpeting. Fixturing can be difficult for textile peel tests because of the wide variety of materials that may be used. Also, peel tests can be conducted as 90 degree peel, 180 degree peel, or T-peel tests and may use a peel table, backplate grips, or standard tensile grips and jaws, depending on the specific product, bond type, and standard test method being used. ASTM has specified standard test methods for the various textile peel tests used in industry to provide for consistent testing methods and comparable data between products and manufacturers. Popular standards are ASTM D413 for adhesion of fabric and rubber, ASTM D2724 for bonded, fused, and laminated apparel fabrics, ASTM D3936 for delamination of pile yarn carpet backing, and ASTM D4393 for textile reinforcing and rubber. Textile peel tests can be conducted using low force, constant rate of extension tabletop tensile test machines. The machines below are configurable with tensile grips and peel tables to meet ASTM textile peel test requirements. The grips below are representative of the grip styles which can be manufactured to your specific test requirements.
