Test method for pilling abrasion of fabrics
Measurement methods: 1. Pilling box 2. Random tumbling pilling test 3. Wear testing machine for pilling test 1. Pilling box: sample (125 mm×125mm) is cut from the fabric (2 for warp and 2 for weft). Sew face to face and turn around. The fabric tube is mounted on the rubber tube. Stick the loose tape with PVC tape. All four samples are then placed together in a cork-lined box of 9“×9”×9“×”, and allow the required revolution cycle. Specimens were removed and removed from the rubber tube and assessed. At the same time, the main reason for pilling is that the fibers have a high“Lateral strength”or“bending”or“low brittleness”. high“Lateral strength”May be advantageous in some applications such as technical textiles, floor coverings etc. However, the pilling trend has also increased, so in the apparel industry“low lateral strength”is desirable, especially in knitted products. Polyester fibers are intentionally brittle for use in knitted products to avoid pilling (anti-pilling type). Pellets do not form low transverse strength fibers (wool and pill-resistant rayon). They can be easily wiped off. But fiber with the power of the high side”There will be higher pilling. Anti-pilling performance and durability are negatively correlated. Pilling Grade: Grade 5 No or very weak pills. Grade 4 weak pills. Grade 3 moderate pellets. Class 2 distinct pellets. Level 1 drug strength. 2. Random tumbling pilling test: random tumbling motion of tumbling in a cylindrical test box made of light abrasive materials. For a tablet similar to actual wear, add a small amount of cotton fibers. Three specimens 105mm x 105mm with chamfered 45° lengths and edges sealed with rubber adhesive. All of these samples were dropped into the test chamber along with the cotton. The fabric samples are evaluated over time. The number and time of cycles depends on the type of fabric and will be specified in the relevant specification. 3. Abrasion tester for pilling test: Specimens are mounted on large (bottom) and small (top) specimen holders. Then rub against each other (source sample). 2 The pressure is: 2.5/cm of knitted fabric. Woven and upholstery fabrics 6.5. In standard abrasives, fabric samples are placed on the lower rack. If the pilling degree differs from the rack, the upper sample is evaluated. The number and time of cycles depends on the type of fabric tested and will be specified in the relevant specification.

Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
