II. Product description
Stab-proof: The stab-proof inner core is composed of 16 layers of high-performance polyethylene, and the stab-proof vest's stab-proof layer is made of a black dense waterproof and light-proof protective cover.
Stab resistance was tested at room temperature using standard test tools and counterweights, resulting in a 2.4 kg drop. The impact energy of 24J plus or minus 0.5J can effectively sprint into the stab-resistant clothing at 0 degrees, 45 degrees, and penetration angles. The tip of the knife will not penetrate.

Bulletproof: Protective layer structure: The protective layer structure of bulletproof stab-proof clothing is composed of 45 layers of polyethylene fiber non-weft cloth (four layers orthogonal) + 1 layer of 4.5mm thick foam.
Composition: The bulletproof stab-proof clothing consists of a jacket, a bulletproof layer and a bulletproof layer protective cover. The jacket is removable and washable, and the shoulder and waist are adjustable.

Sleeve sealing performance: The protective layer is sealed with an anti-seepage and anti-seepage black protective sleeve, and the sealing edge is uniform. The protective cover material is impermeable to water, and the anti-hydrostatic pressure is not less than 18kPa

Wearing flexibility: flexible wearing, easy to put on and take off. After wearing, the free movement of the arm and the human body's kneeling, jumping, running, pitching, turning and other movements should not be significantly restricted.

Ballistic resistance at room temperature: Tested with 1979-style 7.62mm light submachine guns and 1951-style 7.62mm pistol cartridges (lead core). In the case of an effective hit, the bullet is blocked, and the maximum groove depth should be less than or equal to 25mm.

Immersion bulletproof: Under normal temperature, soak the bulletproof stab-proof clothing in water for 30 minutes, and then conduct the bulletproof test. In the case of effective blows, to withstand bullets, the maximum concave depth of the backing should be less than or equal to 25mm.

High temperature ballistic resistance: After high temperature test (+55℃±2℃, constant temperature 4h), test the ballistic resistance within 15min. In the case of an effective hit, the bullet is blocked, and the maximum sag depth of the backing is ≤25min.

Low temperature ballistic performance: After the low temperature test (-20℃±2℃, constant temperature for 4h), the ballistic performance test is carried out within 15min. In the case of an effective hit, the bullet is blocked, and the maximum sag depth of the backing is ≤25min.

Bulletproof damp heat performance: After the damp heat test (70℃±2℃, 80% relative humidity, 240h), the bulletproof performance test is carried out. In the case of effective hitting, the bullet is blocked, and the maximum sinking backing depth is less than or equal to 25min.
