The GESTER GT-KC01 Veslic Rub Fastness Tester is a robust physical testing machine designed to measure the rub color fastness, surface abrasion resistance, and finish adhesion of natural leathers, footwear uppers, synthetic materials, and coated fabrics. As a leading leather testing machine manufacturer supplier, GESTER engineers the GT-KC01 to operate strictly in accordance with ISO 11640, SATRA PM 173, and EN ISO 20344. The machine subjects pre-tensioned specimens to controlled reciprocating linear friction using standardized white wool felt pads under regulated contact loads. It serves as a classic, durable quality control solution for leather tanneries, footwear QC laboratories, and commercial testing facilities worldwide.
The GESTER GT-KC01-1 Veslic Rub Fastness Tester is a benchtop laboratory instrument designed to measure the color fastness and surface wear resistance of leather, footwear uppers, synthetic materials, and coated fabrics. It evaluates finish damage, color transfer, and surface breakdown under regulated cyclic rubbing with standard wool felt in both dry and wet conditions. Compliant with ISO 11640, DIN 4843, and EN ISO 20344, the GT-KC01-1 provides precise, reproducible quality control data for leather tanneries, footwear manufacturers, and automotive interior laboratories.
The GESTER GT-KC01-2 IULTCS & Veslic Tester is a high-efficiency laboratory testing instrument engineered to assess the rubbing color fastness and surface durability of natural leather, synthetic leather, plastics, and coated textiles. Featuring two independent testing stations, the iultcs veslic rub fastness tester allows laboratory technicians to perform simultaneous dry and wet rubbing fastness tests or run parallel sample evaluations, effectively doubling testing throughput. Fully compliant with ISO 11640, SATRA PM 173, and EN ISO 20344, the instrument evaluates finish adhesion, color bleeding, and surface degradation under controlled cyclic pressure using standard white wool felt pads. It is widely used in commercial testing laboratories, tannery R&D centers, footwear manufacturing facilities, and automotive trim production lines.
Leather grain tester, Grain Crack Index Tester, Sole Leather Grain Crack Index Tester: To determine the propensity of the grain of a leather to crack during bending. The method is applicable to all sole leathers.
The Bally Flexing Tester GT-KC10A (Bally Flexometer) is an advanced leather flexing tester designed to accurately determine the resistance of flexible materials—especially leather, coated fabrics, and footwear textiles—to cracking and failure at flexing creases. It performs tests per key international standards (e.g., ISO 5402-1, SATRA TM 55, EN 344-1) with options for 6, 12, or 24 test positions, a 22.5° flexing angle, and a speed of 100 cycles/minute. Supporting both wet and dry specimens, it ensures reliable quality control for manufacturers seeking durable, high-performance leather products.
