IS 8085 (Part 18) & ISO 22776: Hook and Loop Fasteners Test We use a variety of fasteners throughout our lives, and one of the most notable is the ‘hook and loop’ fastener, also known as Velcro. This simple yet powerful design is used in clothing, footwear and consumer products, but have you ever wondered how strong these Velcro fasteners really are? What kind of force can they withstand to keep items safe and secure? Peel Strength and Shear Strength are two important indicators of the performance of hook and loop fasteners. In this article, we will introduce these two test methods and related standards as well as the applicable equipment in detail. 1. Peel Strength Test 1.1 Definition of Peel Strength Peel strength refers to the anti-peeling ability of hook and loop fasteners in the vertical separation direction, usually expressed in N/mm (Newton/mm). This index reflects the adhesion performance of fasteners under repeated opening and closing or force. 1.2 The peel strength tests described herein are based on the standards IS 8085 (Part 18) / ISO 22777. specifies a test method for determining the peel strength of touch and close fasteners before and after repeated use. Test Method: After bonding the hook side and the hair side, fix it on the tensile machine, peel it off at a constant speed and record the peeling force curve. 2. Shear Strength Test 2.1 Definition of Shear Strength Shear strength refers to the shear resistance of hook and loop fasteners in the direction of parallel force, usually expressed in kPa (kPa). This index reflects the stability of the fastener in the lateral force, such as backpack straps, safety belts and other application scenarios. 2.2 The peel strength tests described herein are based on the standards ISO 22776. ISO 22776 specifies the test methods for the shear strength of hook and loop fasteners. Test method: After bonding the hook surface and the hair surface, apply shear force until separation, and record the maximum shear force. 3.

What is The Test for Paper Bending Stiffness? When you unpack a delivery box, Have you ever considered how cardboard stiffness directly affects package compression resistance? Similarly, in the printing industry, how the bending properties of paper determine the flatness of the finished product? All of these key indicators cannot be separated from the accurate testing of paper Bending Stiffness. The GT-N22 Paper Bending Stiffness Tester is designed for this purpose. In this article, we will introduce the GT-N22 paperboard bending stiffness tester 's functions, standards and operating procedures in detail. What is paper bending stiffness test? Paper bending stiffness measures a material's resistance to bending deformation. This property directly impacts its application performance (e.g., packaging load-bearing, printing adaptability, etc.). The GT-N22 paper testing instrument quantifies bending stiffness (in mN·m or N·mm) by simulating real-world force conditions, ensuring that the material complies with industry standards and end-use scenarios. The bending stiffness can be used for testing the bending stiffness performance of film, mica sheet, graphite sheet, composite material and other sheet materials. Paper Testing Instruments Relevant Standards The bending stiffness tester complies with the following standards: GB/T 2679.3 (Determination of paper and cardboard stiffness) GB/T 22364 (Determination of bending stiffness of paper and cardboard) ISO 2493-1 (Determination of bending stiffness of paper and paperboard) ISO 5628-2019 (Determination of static bending stiffness of paper and paperboard) GT-N22 Paperboard Bending Stiffness Tester Operation Guide Step 1: Turning on the power and setting parameters Turn on the power switch. Press “SETTING” to enter the test parameter setting interface. Set the key parameters (other parameters have been preset in the factory, no need to adjust): Test Speed (test speed): 0.5-50 ° / sec. Bend Length (bending length): optional 5, 10, 15, 20, 25, 30, 40, or 50 cm Bending Angle：1-92° Pause Time: Adjust as needed (default 0 seconds) Quanti (sample weight): enter the sample grams (g / ㎡) Step 2: Sample Mounting and Positioning Click “RETURN” to reset the rotary fixture to its home position. Turn the rotary knob to open the fixture, make sure the protruding end of the sample is over the position of the test head, and then tighten the nut to fix it. Adjust the force arm scale: according to the preset bending length (e.g. 10mm), pull out the locating pin and push the force arm to the corresponding scale, re-insert and lock it. Note: Unaligned or loosely clamped samples will result in measurement inaccuracies and need to be double-checked!

Understanding Upholstery Fabrics Sewn Seam Dynamic Fatigue Tester GT-KB40 You may have come across furniture fabric testing, but do you really understand the importance of seam fatigue testing? In furniture manufacturing and automotive interiors, the strength of fabric seams is a key factor in determining product lifespan. Under long-term repeated stress, seams may break due to dynamic fatigue, leading to fabric delamination, fraying, and even structural failure. How can we accurately assess seam durability? GT-KB40 Seam Dynamic Fatigue Tester is professional equipment for assessing the durability of seams in upholstered furniture such as sofas and car seats. In this article, we will analyze the working principle and operation procedure of GT-KB40 Seam Fatigue Tester in detail. Working Principle of GT-KB40 Seam Fatigue Tester The Sewn Seam Dynamic Fatigue Tester measures and visually evaluates yarn slippage and other types of failures in the three most commonly used The dynamic seam fatigue tester is to measure of or visual evaluation of yarn slippage and other types of failures in the three most commonly used upholstery seams - warp sewn to warp (wale to wale), filling sewn to filling (course to course), and warp sewn to filling (wale to course). Stress on the seam is created through cyclic impact and penetrating loads that fatigue the seam structure. GT-KB40 Seam Fatigue Tester for Fabric Operating Procedures Specimen Preparation Cut a standard specimen (including seams), ensuring that the seam line is centered on the foam pad (279.5 x 228 x 178 mm). Fix the foam pad in the specimen slot, align the fixture with the slot using the locating pin, press and lock the front fastener. Equipment Alignment Use a straightedge to confirm that the distance between the specimen surface and the impact hammer is 150mm, and fine-tune the height through the four adjusting nuts at the bottom. Connect ≥0.6MPa gas source and AC220V power supply, start the dynamic seam fatigue tester and perform system zeroing. Test execution Select the automatic mode, close the idle station, set the number of impacts (e.g. 5000 times). Pull out the fixed pin of the impact hammer, click the start button, the equipment will automatically run to the set number of times and then stop. Evaluation of results When the impact reaches the set number of times, the machine stops automatically. Observe the seam condition on the surface of the sample. FAQ Q: What types of seams can the Seam Fatigue Tester for Fabric  test? A: Three main types of seams are supported: warp to warp, weft to weft, and warp to weft. Q: How are the test results presented? A: The dynamic seam fatigue testing machine can output data such as seam slippage and breaking strength decay curve.
