Principle of flame retardant durability of pure cotton flame retardant fabric
In recent years, with the rapid development of my country’s economic construction and the improvement of laws and regulations, the demand for flame-retardant textiles has grown rapidly, and the corresponding standards and regulations for flame-retardant textiles have also been gradually improved:
For textiles used for decoration in buildings, the national standard GB8624 combustion performance classification method for building materials has been formulated. The main indicators are aerobic index, damage length, smoldering time, and afterburning;
The national standard GB17951 for flame-retardant woven fabrics (flame-retardant fabrics and flame-retardant decorative fabrics) has been formulated. The main indicators include damage length, smoldering time, afterburning time, breaking strength, and tearing strength;
The textile industry standard FZ77001 flame-retardant polyester knitted fabric has been formulated for polyester knitted fabrics. The main indicators include damage length, smoldering time, afterburning time, and wash resistance;
In terms of protective clothing, the national standard GB8965 for flame-retardant protective clothing has been formulated. The indicators that flame-retardant fabrics must meet and the relevant requirements for clothing. The main indicators include damage length, smoldering time, afterburning time, and washability. , breaking strength, tearing strength, breathability and clothing-related indicators;
In terms of fire protection clothing, for ordinary fire protection clothing, the Ministry of Public Security has formulated the public safety industry standard GA10 performance requirements and test methods for firefighters’ ordinary protective clothing. The main indicators are flame retardant performance, wash resistance, abrasion resistance, fabric strength, and waterproof performance. etc;
For fire-fighting insulation clothing, the Ministry of Public Security has formulated the public safety industry standard GA88 performance requirements and test methods for fire-fighting insulation clothing, which mainly include flame retardant performance, thermal insulation performance, fabric strength, water-proof performance, etc. At the same time, my country stipulates the production, Sales of flame-retardant textiles and related products must obtain a production or operation license from the State Administration of Work Safety.
In flame retardant standards, important indicators include flame retardant performance, including damage length, smoldering time, afterburning time, and wash resistance. Secondly, there are other auxiliary properties of the fabric, such as strength, breathability, etc. In the actual production process of durable flame-retardant fabrics, the washing resistance of flame-retardant finishing fabrics is the key to whether the finishing process is suitable. When the washing resistance meets the requirements, other properties of the fabric should be considered, such as strength, feel, wear resistance, color, etc.
