Breaking strength: warp and weft ≥ 650N.
Tear strength: warp and weft ≥ 100N.
Thermal stability: 260 ℃, 5min, shrinkage ≤ 10%, no surface change.
Hydrostatic pressure: ≥ 17Kpa.

Third, the method of dress clothing

Only in jacket and trousers were worn and proper closure to ensure the performance of clothing, dress according to the following methods must be properly dressed.
