Description

Technical Field

[0001] The invention belongs to the technical field of textile testing, and in particular relates to a device for testing the flame retardant performance of textiles. Background Art

[0002] According to statistics, about 20% of residential fires are caused by textiles, and more than 50% of deaths are caused by these textile fires. Therefore, giving textiles flame retardant functions is of great significance for eliminating fire hazards, hindering the spread of fire, and reducing the loss of life and property. The so-called "flame retardant" does not mean that textiles after flame retardant finishing will not burn when exposed to fire, but that the fabric can reduce its flammability as much as possible in the fire, slow down the spread of fire, and prevent large-scale combustion. After leaving the flame, it can quickly extinguish itself and no longer burn or smolder.

[0003] Common textile flame retardancy testing methods include vertical burning method, 45° burning method, horizontal burning method, etc. 1. Vertical burning method: mainly used for flame retardancy testing of clothing textiles, curtains and other fabrics. 2. 45° burning method: mainly used for flame retardancy testing of clothing textiles. 3. Horizontal burning method: mainly used for combustion performance testing of children's sleeping bags and blankets.
