The flame retardant used in flame retardant fabrics is a durable post-finishing flame retardant used for cotton fiber and its blended fabrics. Its main feature is that after using this flame retardant to produce and finish, the fabric has a durable resistance. Burning function.
BS7177 (BS5807) is suitable for fabrics such as furniture and mattresses in public places in the UK. Special requirements for fire resistance, strict testing methods. The fire is divided into eight fire sources of 0-7 levels, respectively, for the four fire levels of low, medium, high and extremely high hazard.
BS7176 is suitable for furniture covering fabrics, requiring fire resistance and washing resistance. During the test, the fabrics and fillers are required to meet Schedule 4 Part 1, Schedule 5 Part 1, and smoke density, toxicity and other test indicators. It is a stricter fire protection standard for cushion seats than BS7175 (BS5852).
CA-117 (TB117) is a widely used one-time fire protection standard in the United States. It does not require post-water testing and is suitable for most textiles exported to the United States.
GB8965-98 China National Flame Retardant Clothing Standard
In 1998, the National Bureau of Standards and Standards of China promulgated the industrial flame-retardant clothing standard in accordance with the 1988 standard of the same name and the same international standard, and made detailed regulations on the following aspects: Combustibility, mechanical properties of clothes, structural design of clothes, processing and manufacturing, marking and packaging of finished products, inspection methods, etc.
GA10-91 Chinese firefighters' general protective clothing performance requirements and test methods.
The fire-resistant and flame-retardant fabric will go out immediately after leaving the fire, depending on the temperature and airflow (oxygen) of the fire site and the length of time in this high-temperature environment. If the oxygen index of the textile material is above 21% (the oxygen concentration in the natural air is 21%), the textile product is self-extinguishing. According to the extreme oxygen index, fabrics are usually divided into flammable (LOI less than 20%), flammable (LOI equal to 20%-26%), non-flammable (LOI equal to 26%-34%) and otherwise (LOI> 35%) Four levels.
