Detailed Description

The present application is described in further detail below with reference to figures 1-5.

Example 1:

the embodiment of the application discloses high-rigidity weftless fabric. Referring to fig. 1 and 2, a high-rigidity weftless fabric includes a polyethylene fiber layer 1 and a reinforcing layer 2. The reinforcing layer 2 is provided with two layers which are respectively positioned at two sides of the polyethylene fiber layer 1. The reinforcing layer 2 is covered on the polyethylene fiber layer 1 in a grid shape. And the reinforced layer 2 is formed by spraying and spinning PE fibers and inorganic fibers. The spreading width of the polyethylene fibers in the polyethylene fiber layer 1 is 2.0 cm to 3.0 cm. The cross section of the PE fiber is polygonal, namely the PE fiber is a profiled fiber. The inorganic fibers include carbon fibers or glass fibers.

Through the compounding of different material layers, the rigidity of the weftless fabric is further enhanced, the mechanical effectiveness of the fabric is improved, the weftless fabric has better bulletproof performance, and the weftless fabric can be used in more service environments requiring high rigidity.

Example 2:

referring to fig. 3, example 2 is different from example 1 in that the polyethylene fiber layer 1 is provided with two layers, one on each side of the reinforcing layer 2. The reinforcing layer 2 has the same area as the polyethylene fiber layer 1 and completely covers the polyethylene fiber layer 1. The rigidity of the non-woven fabric is increased as much as possible under the condition of saving materials.

Example 3:

the embodiment 3 of the application discloses a bulletproof chest inserting plate made of high-rigidity weftless cloth. Referring to fig. 4 and 5, the bulletproof chest insert plate made of high-rigidity non-woven fabric comprises an insert plate body 3 and a plurality of adjusting sheets 4. The board body 3 is made of a non-woven fabric, which is the non-woven fabric described in embodiment 1 or embodiment 2. The inserting plate body 3 is bent to form a curved surface which is attached to a human body. The adjusting pieces 4 are sequentially arranged and mutually abutted, and one side of one adjusting piece 4 is abutted to the inserting plate body 3.
