Embodiment 1

[0039] The manufacturing steps of the stab-proof clothing of the present embodiment are:

[0040] 1) Manufacture of non-weft fabric

[0041] Prepare a glue solution with a solid content of 40% from water-based polyurethane adhesive and put it into the glue tank. The aramid fiber is dipped in the glue tank, spread out, and fixed on the layout machine. At the same time, the glue solution is spread evenly with a scraper blade. After drying completely at 110°C, the first fiber cloth is obtained; rotate the first fiber cloth by 90 degrees, then spread a hot-melt adhesive film of the same size on it, and fix it with the first fiber cloth at the edge with double-sided adhesive According to the method for preparing the first fiber cloth, the second fiber cloth is prepared on a hot-melt adhesive film with a thickness of 0.08mm, the difference is that the drying temperature is 130°C; when the drying of the second fiber cloth is completed, What is obtained is the described non-weft clot...

Embodiment 2

[0049] The manufacturing steps of the stab-proof clothing of the present embodiment are:

[0050] 1) Manufacture of non-weft fabric

[0051] Prepare a glue solution with a solid content of 30% from water-based polyurethane adhesive and put it into the glue tank. The aramid fiber is dipped in the glue tank, spread out, and fixed on the layout machine. At the same time, the glue solution is spread evenly with a scraper blade. After drying completely at 110°C, the first fiber cloth is obtained; rotate the first fiber cloth by 90 degrees, then spread a hot-melt adhesive film of the same size on it, and fix it with the first fiber cloth at the edge with double-sided adhesive According to the method for preparing the first fiber cloth, the second fiber cloth is prepared on a hot-melt adhesive film with a thickness of 0.05mm, the difference is that the drying temperature is 120°C; when the drying of the second fiber cloth is completed, What is obtained is the described non-weft fabr...

Embodiment 3

[0059] The manufacturing steps of the stab-proof clothing of the present embodiment are:

[0060] 1) Manufacture of non-weft fabric

[0061] Prepare a glue solution with a solid content of 30% from water-based polyurethane adhesive and put it into the glue tank. The aramid fiber is dipped in the glue tank, spread out, and fixed on the layout machine. At the same time, the glue solution is spread evenly with a scraper blade. After drying completely at 110°C, the first fiber cloth is obtained; rotate the first fiber cloth by 90 degrees, then spread a hot-melt adhesive film of the same size on it, and fix it with the first fiber cloth at the edge with double-sided adhesive According to the method for preparing the first fiber cloth, the second fiber cloth is prepared on a hot-melt adhesive film with a thickness of 0.05mm, the difference is that the drying temperature is 120°C; when the drying of the second fiber cloth is completed, What is obtained is the described non-weft fabr...

Abstract

The invention provides comfortable stab resistance body armor and a manufacturing method thereof. The comfortable stab resistance body armor comprises a jacket and stab resistance materials arranged in the jacket, and the stab resistance materials comprise a stab resistance chip and buffer materials; the stab resistance chip is formed by overlapping at least 16 layers of laid fabric according to 0/90 DEG orthogonally; the laid fabric is composed of two layers of fiber cloth and a hot melt adhesive film; the hot melt adhesive film is arranged between the two layers of the fiber cloth; the two layers of the fiber cloth are overlapped according to 0/90 DEG orthogonally; and the fiber cloth is formed by bonding fibrils with adhesive. The stab resistance body armor is high in comfort, and the manufacturing technology is simple and practicable.

Description

technical field [0001] The invention relates to a protective product, in particular to a comfortable stab-resistant garment and a manufacturing method thereof. Background technique [0002] Stab-proof clothing is a kind of protective equipment used to attack sharp instruments such as knives. According to its development process, stab-resistant clothing can be divided into rigid, semi-rigid and soft stab-resistant clothing. Among them, rigid and semi-rigid stab-resistant clothing have excellent stab-resistant properties, but their stab-resistant layers are thicker, poor wearing comfort, and insufficient flexibility. Compared with traditional hard and semi-rigid stab-resistant materials, soft stab-resistant clothing is composed of fiber composite materials, which usually have the characteristics of light weight, greater energy absorption per unit, more convenient and comfortable wearing, and excellent comprehensive performance. It is in line with the development trend of hum...
