Testing the pilling performance of modal fiber knitted fabrics with a box-type pilling tester
The box-type pilling tester is used for pilling or snagging caused by normal wear and tear. It is equipped with a unique controller, optional standard and other test speeds for testing, and is equipped with a programmable 30rpm reversing system. Box-type pilling tester is widely used in textile pilling test, and has certain requirements for different standards. (Hong Kong) Co., Ltd. is a manufacturer, and customers in need are welcome to inquire. Applicable standards: GB/T4802.3, ISO12945.1, BS5811, JISL1076, IWSTM152 Main parameters: 1. Number of pilling boxes: 4; 2. Box size: 235×235×235mm; 3. Cabinet speed: 60±2r/min; 4. Counting range: 1～99999 times; 5. Sample tube: shapeΦ31.5×140mm, 4 pieces/box; 6. Power supply: AC220V±10%, 50Hz, 120W. Modal fiber knitwear is soft, smooth, silky, comfortable to wear, has excellent breathability and moisture absorption, has silk-like luster, bright color and other characteristics. Close-fitting knitted underwear generally requires functions such as comfort, softness, breathability, warmth, elasticity and so on. In order to meet the above requirements, in recent years, in addition to natural fiber cotton, knitted underwear has also used a large number of cellulose fibers with similar functions to cotton fibers. Modal and man-made fibers are now the most used. Test principle: Put three samples of the same size into the tester equipped with standard cork, the samples roll in the cylinder with stirring rod, and rub against other samples or the wall of the cylinder, resulting in pilling. Usually, take it out after 30min of high-speed free rotation. After the excess debris is sucked by a vacuum cleaner, under standard visual conditions, compare it with the standard sample, and evaluate the pilling and pilling of the fabric by grades, grade 1, grade 5. Well, there are half levels allowed.

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.
Ball Burst Method (ASTM D3787): Steel ball penetration for textiles/films using testers like GT-C02-2.
