What are the types of flame retardants commonly used in fabrics?
Fabric burning performance test and fabric flame retardant performance test are standards that must be tested by many textile industries. The flame retardant effect of textiles is generally the addition of chemical properties such as flame retardants. Therefore, different flame retardant additives can be selected for the flame retardant effect of textiles. In this article, the Engineering Department will focus on the types of flame retardants commonly used in fabrics. 1. Classification according to the flame-retardant elements contained 1. In the pyrolysis process of halogen-containing flame retardants, X·and HX are decomposed to capture and transmit combustion free radicals. HX can dilute the combustible gas generated during fiber cracking, or block the contact. 2. Phosphorus-containing flame retardants produce phosphoric anhydride or phosphoric acid during the combustion process, which promotes the dehydration and carbonization of textiles and prevents or reduces the production of combustible gases. In addition, phosphoric anhydride forms a glass-like melt when it is pyrolyzed to cover the fabric, prompting its oxidation to generate carbon dioxide, which plays a flame-retardant effect. 3. Nitrogen-containing flame retardant nitrogen compounds can act with cellulose to promote cross-linking into charcoal, reduce the decomposition temperature of fabrics, and produce non-combustible gas, which can dilute the combustible gas. 2. Classification according to the durability of flame-retardant fabrics 1. Non-durable flame-retardant finishing agent, temporary flame-retardant finishing agent. Most of them are water-soluble or emulsion inorganic salts. When treating, dissolve the flame retardant in water first. The fabric can be used after immersion and drying. There is also a two-bath padding. The second bath uses ammonia or soda ash to deposit metal oxides on the fabric. This method is simple in process and low in price, but the fabric has a poor hand feeling, and the flame retardant effect after washing is greatly reduced. 2. Semi-durable flame-retardant finishing agent. Its flame-retardant products can withstand one-time mild washing, but are not resistant to high temperature soaping. The method includes urea-phosphoric acid method, urethane phosphate method and so on. 3. The durable flame-retardant finishing agent uses chemical methods to polymerize or condense on the inner surface of the fiber to form a water-insoluble polymer. Generally, it is required to be washed more than 30 times. Different types of flame retardants should be used for knitted fabrics of different materials to obtain better flame retardant effects. Decorative fabrics are deeply loved by consumers for their gorgeous appearance and comfort performance. Therefore, when the fabric is flame-retardant finishing, it is necessary to fully consider the effect of flame retardants on the color, appearance, feel and other physical and mechanical properties of the fabric.

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.
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.
