Fabric moisture wicking test method for heat and moisture transfer
At present, the commonly used test methods for fabric heat transfer mainly include flat-panel moisturiser and fabric precision thermal property tester; the commonly used test method for moisture transfer is the moisture permeable cup; the apparatus for clothing heat transfer test is sweating to warm people dummy. 1. The flat-panel moisturizing instrument adopts the method of placing the fabric on a hot plate with a constant temperature and considering the heat required to maintain the constant temperature of the hot plate, that is, the constant temperature difference heat dissipation method. This instrument is suitable for measuring the moisturizing performance of various fabrics. The domestically established test standards are GB 11048-89 and so on. By covering the sample on the test board, the test board, the bottom plate and the surrounding protection board are controlled to the same temperature by electric heating, and the constant temperature is maintained by the way of on and off, so that the heat of the test board can only be dissipated in the direction of the sample , determine the heating time required for the test panel to maintain a constant temperature for a certain period of time, and calculate the thermal retention rate of the sampleβ, thermal conductivity K and Crow value CLO. 2. The fabric precision thermal property tester is fast and precise in thermal testing, and is widely used in the thermal transfer performance testing of fabrics. The heat is transferred to the fabric through the heating plate and diffused to the environment, the electric energy consumed by the heating plate is measured, and the thermal conductivity K, thermal resistance Rd and thermal retention rate of the fabric are calculated.β. 3. The moisture permeable cup test method is the main method of fabric moisture permeability test and has a wide range of applications. Many test standards have been established at home and abroad, such as: ASTM E96-00, ISO 2528, JIS L1099-1985, GB/T 12704-91, etc. The moisture permeable cup tests the moisture permeability of a fabric, which is to place the fabric in a humidity gradient at a certain temperature, and test the amount of water vapor permeating a unit area of the fabric in a unit time. The moisture permeable cup method can be divided into moisture absorption method and evaporation method. The moisture absorption method simulates the degree of moisture of an absolutely dry object: the evaporation method simulates the speed of sweat vapor passing through the fabric. 4. The sweating body warming dummy is an ideal test equipment for the research on the thermal insulation value of clothing. Its body shape, segment division, joint activity, metabolic heat production, body surface temperature distribution, skin radiation coefficient, etc. are all in line with the anatomical and physiological characteristics of the human body. It can simulate the temperature distribution of the human body surface and conduct thermal studies related to the human body. The indicators for the thermal and humidity comfort test of clothing using the thermal dummy are the moisture resistance Re, the moisture permeability and the thermal resistance Rd.

Personal protective equipment must meet specific performance requirements before it can be used in demanding workplace environments. ISO, EN, and ASTM standards provide important test methods and performance requirements for different PPE categories. However, the applicable standard depends on the product, intended application, target market, and specific protection requirements.
This guide explains the role of ISO, EN, and ASTM standards in PPE testing and introduces common requirements for safety footwear, protective gloves, protective clothing, masks, and safety helmets. It also explains how laboratories can select suitable PPE testing equipment according to the applicable test method.
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.
The air permeability tester is a high-precision testing instrument designed to evaluate the breathability of PPE materials, textile fabrics, non-woven fabrics, woven fabrics, and industrial filter media. It plays a critical role in quality control, product development, and laboratory research across multiple industries including PPE, textiles, automotive interiors, and filtration systems.
Modern instruments such as the GT-C27 Air Permeability Tester are developed with advanced sensor systems, automated control logic, and multi-standard compatibility to ensure reliable and repeatable results. Complying with global standards such as ISO 9237, ASTM D737, DIN 53887, and GB/T 5453, it guarantees internationally recognized testing performance.
With high automation, accurate pressure sensing, and flexible unit conversion systems, air permeability testing equipment significantly improves testing efficiency while reducing human error. It is widely used in PPE manufacturing, textile engineering, non-woven product development, and industrial filtration quality inspection.
