Abstract:

In order to improve the thermal protective performance of honeycomb fabric for firefighter protective clothing, the honeycomb hole structure optimization and evaluation were carried out for the thermal barrier. The current typical fabrics of firefighter protective clothing were chosen as the experimental samples. Considering thermal liner layering, honeycomb side length and wall thickness, six kinds of hole sizes were designed for the straight holes and the inclined holes respectively, and a solid control group was presented. Then 13 sets of experimental schemes were prepared by laser cutting technology and a thermal protective performance tester was adopted to perform the flash fire test. The experimental results show that honeycomb layering reorganization effectively improves the thermal protective performance of honeycomb fabric systems for firefighter protective clothing. By the non-parametric correlation sample test, a significant difference exists in the thermal protective performance of the honeycomb sandwich structure with different opening methods, and the inclined hole structure has better thermal protective performance than the straight hole.

Key words: firefighter protective clothing, honeycomb fabric, thermal protective performance, structure optimization, comfort performance
