Description

Technical Field

[0002] Protective clothing is a specially designed garment used to protect the wearer from various physical, chemical, biological and other harmful factors. Different types of protective clothing are suitable for different working environments and dangerous conditions. Flame-retardant protective clothing is mainly used in environments where there is a risk of fire, such as the petrochemical, electric power and other industries. It is made of flame-retardant materials and can quickly carbonize when exposed to flames to form an insulating layer to prevent heat from being transferred to the body and protect personnel safety. Before using protective clothing, it is usually necessary to conduct flame-retardant testing on the protective clothing to ensure subsequent safety.

[0003] Publication No. CN104101682B discloses a fabric flame retardancy tester, which belongs to the field of fabric testing technology. It solves the technical problems in the prior art such as the inability to test the flame retardancy of unsewn fabrics. The tester includes a bottom plate arranged in the horizontal direction, a slide plate is slidably connected to the bottom plate, and a positioning structure 1 is arranged between the slide plate and the bottom plate to enable the two to be relatively fixed; the tester also includes a rocking plate, the inner end of the rocking plate is hinged on the slide plate, and a positioning structure 2 is arranged between the rocking plate and the slide plate to enable the two to be relatively fixed, and a flamethrower is arranged on the plate surface of the rocking plate; the tester also includes two sliding rods arranged in the vertical direction, the lower end of the sliding rod is vertically fixed to the bottom plate, and the tester also includes three clamping rods slidably arranged on the sliding rods, a gap for clamping the fabric is formed between the two clamping rods near the upper end of the sliding rods, and a positioning structure 3 is arranged between the clamping rod and the sliding rod to enable the two to be relatively fixed.

[0004] Although the above application and the prior art can realize the flame retardancy test of unsewn fabrics, due to the different flame retardancy effects of different parts of the protective clothing, when using the device, only a single part of the protective clothing can be tested, and multiple parts of the protective clothing cannot be tested. In addition, during the actual use of the protective clothing, wrinkles will appear on the surface of the protective clothing due to the wearing of the protective clothing by people. When the fabric is tested using the device, it is impossible to test this situation, so the test results will be limited. After the protective clothing is burned, carbonization will appear on its surface, which will lead to the inability to directly test the protective clothing during subsequent testing due to the carbonization. Therefore, we propose a flame retardancy detection device and method for composite fabrics of protective clothing. Summary of the invention
