Flame retardancy | The flame retardant performance test shall be conducted for the fabric and the reinforcing materials at the shoulder, knee, hip, elbow and other parts after 25 times of washing. The longitudinal damage length is ≤ 44mm, and the latitudinal damage length is ≤ 41mm. The afterburning time is 0s in the longitudinal/latitudinal direction, and there shall be no melting and dripping. |
The surface moisture resistance of the fabric | 4-5 |
Breaking strength | Fabric breaking strength in warp direction ≥ 950N, and breaking strength in weft direction ≥ 860N |
Breaking strength | Fabric breaking strength in warp direction ≥ 950N, and breaking strength in weft direction ≥ 860N. |
Tear strength | The warp tear strength of the fabric ≥ 190N, and the weft tear strength ≥ 150N. |
Thermal stability | After the thermal stability test at 180 (± 5) ºC, the size change rate of the fabric and the reinforcing materials at the shoulder, knee, hip, elbow and other parts along the warp and weft directions is 0%, and the surface of the sample should have no obvious change. |
Color fastness. | The color fastness to water rubbing, washing and staining, and light fastness of the fabric shall be ≥ 4 grades. |
Color difference | The color difference between front collar and front, sleeve and front, pocket and front, left and right front and other surface parts is 4-5. |
