Problems solved by technology
[0002] Ordinary non-weft fabrics are mostly used in industries, such as chemical and environmental protection industries. Due to their low performance, they are rarely used in bulletproof protective products.
[0003] At present, there is a full-diameter wire laying and dipping line represented by companies in the United States and the Netherlands. The product is made of "UD" cloth with four layers of fibers orthogonally compounded in pairs. This method has the advantages of uniform laying, production The advantages of high efficiency also have the disadvantages of large equipment investment, complicated process and cumbersome operation

Embodiment Construction
[0010] The high-density polyethylene film is used as the matrix, and the high-performance PE fibers are evenly arranged on the film. By spraying thermoplastic high-toughness glue, the fibers and the fibers and the film are tightly bonded to form a unidirectional non-woven fabric, and then passed through Orthogonal stacking, hot pressing into a composite non-woven fabric "UD".
[0011] The production process is:
[0012] Laying HDPE film → high-performance PE fiber → laying silk → spraying adhesive → drying and forming → slicing → unidirectional non-woven fabric;
[0013] Unidirectional non-weft fabric transverse direction—orthogonal compounding→hot pressing→cooling forming→composite non-weft fabric (“UD”).
[0014] Determine the circumference of the roller according to the user's needs;
[0015] Determine the surface density of the non-weft fabric according to user requirements;
[0016] Determine the glue content according to user requirements;
[0017] Choose adhesives a...

Abstract
The present invention relates to a method for making PE weftless fabric plate material. It adopts composite weftless fabric as base material, and utilizes the following steps: using more than two layers of high-performance PE one-way weftless fabrics, crossed laminating every layer according zero deg. / 90 deg. heating to 122-128 deg.C, applying 5 MPa pressure, preheating, when the interior temp. of weftless fabric is rised to 125 deg.C, applying 10-25 MPa pressure, retaining constant temp. and constant pressure for 30-40 min, cooling hot plate, retaining constant pressure and cooling to 30-40 deg.C so as to can obtain the invented product. It can adopt aramid fibre one-way weftless fabric, also can adopt high-strength high-modulus polyethylene fibre one-way weftness fabric and aramid fibre one-way weftless fabric mixture.
Description
Technical field: [0001] The invention relates to a method for manufacturing a high-performance, high-strength, and high-modulus PE fiber composite non-weft cloth plate, and relates to the physical manufacturing method of the composite fiber non-weft cloth and the technical field of application of bulletproof protective products. Background technique: [0002] Ordinary non-woven fabrics are mostly used in industries, such as chemical and environmental protection industries. Due to their low performance, they are rarely used in bulletproof protective products. [0003] At present, there is a full-diameter wire laying and dipping line represented by companies in the United States and the Netherlands. The product is made of "UD" cloth with four layers of fibers orthogonally compounded in pairs. This method has the advantages of uniform laying, production The advantages of high efficiency also have the disadvantages of large equipment investment, complicated process and cumbersom...
