Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] see figure 1 As shown, a fabric protection performance evaluation device is used to fix the fabric 10 to test the fabric 10. The fabric protection device includes a support 1, a fabric deformation that is fixed on the support 1 to fix the fabric 10 and deform the fabric 10. The adjusting device 2, the disaster source 3 arranged on one side of the fabric deformation adjusting device 2, the heat flow meter 4 arranged on the fabric deformation adjusting device 2 to detect the heat flow passing through the deformed fabric 10, and the heat flow meter 4 arranged on the fabric deformation adjusting device 2 The pressure sensor 5 used to detect the pressure generated by th...

Abstract

The invention relates to an evaluation device for a protection performance of a textile and particularly relates to an evaluation device for a stress deformation protection performance of a multifunctional textile. A human body simulator with an arc-shaped surface or an air simulator with an arc-shaped abut-joint surface, and a stretching device are adopted to realize different bending, stretching and shearing deformation states of a heat protection textile, so that the protection performance of textile deformation caused by a human body joint movable part in a work environment can be relatively really simulated; the influences of the factors, which are ignores by an existing protection performance evaluation device, on the thermal protection performance are made up; the evaluation device has the very important real meaning on protecting the life safety of staff and researching high-tech thermal protection equipment.

Description

technical field [0001] The invention relates to a fabric protection performance evaluation device, in particular to a multi-functional fabric force deformation protection performance evaluation device. Background technique [0002] At present, the thermal protection performance evaluation of fabrics mainly uses comprehensive thermal protection performance tester (TPP tester), radiant heat protection performance tester (RPP tester) and high temperature liquid protection performance tester. Its main principle is to expose the fabric to a specific heat source environment, and place a copper sheet heat flow meter on the other side of the fabric to measure the heat flow through the fabric, and record and predict the heat required for the human skin to achieve second-degree burns through the data collector. Time, so as to evaluate the protective performance of the thermal protection fabric system. Under these laboratory simulated conditions, the fabric is in a flat, relaxed state...
