Flame-retardant fabrics are processed with special production techniques to effectively prevent the spread of flames. Textiles after flame-retardant finishing will not burn when exposed to a fire source, but mean that the fabric can reduce its flammability in flames and slow down the spread of flames. The speed is high and does not cause large-area burning; and after leaving the flame, it can quickly self-extinguish and no longer burn or smolder. Has good durable washing performance.
1. Vertical method
This test method stipulates that the sample is placed vertically (the length direction of the sample is perpendicular to the horizontal line), and the combustion source ignites the sample below the sample. , test the minimum ignition time, afterburning time, flame retardant time, flame spread speed, charring length (damage length), charring area (damage area) and other indicators related to flame retardant performance of the sample. The vertical burning method is mainly used for flame retardant testing of clothing textiles, curtains and other fabrics.
2. 45° tilt method
This test method stipulates that the sample is placed at an angle of 45° (the length direction of the sample forms an angle of 45° with the horizontal line), and the combustion source is in the sample. Ignite the sample on the upper or lower surface below, measure the time required for the sample to burn upward for a certain distance, or measure the afterburning, flame retardant time, flame spread speed, charring length, charring area or measurement test after the sample is burned. The number of times the sample needs to be exposed to flames when burning to a certain distance from the lower end of the sample and other indications related to the flame retardant performance. The 45° tilt method is mainly used for flame retardant testing of carpets and other fabrics.
3. Horizontal method
This test method requires the sample to be placed horizontally, igniting the head end of the sample, and measuring the distance and spread of the flame on the sample. The time taken for this distance is used to calculate the burning rate, which is used to characterize the flame retardancy of the fabric. The horizontal method is mainly used for flame retardant testing of automotive interior decoration materials.
