A first loom is mainly provided in the manufacturing process, which generates a single-direction warp yarn, and combines a plurality of warp yarns to form a ground yarn. The invention further A second weaving machine is provided. The second weaving machine sprays the weft yarn along the vertical direction of the bottom yarn and covers the bottom yarn. Finally, the needle yarn is combined with the bottom yarn to form a non-woven reinforcing structure.

The manufacturing method of the above-mentioned non-woven reinforcing structure includes: a ground yarn manufacturing process, in which a composite fiber is sprayed on a non-woven fabric through a first loom to form more than one warp yarn, and a plurality of warp yarns are arranged to form a ground yarn; a reinforcing weft yarn manufacturing process The aforementioned first loom is provided with a second loom in a vertical direction, and the second loom is arranged above the ground yarn, and the second loom ejects composite fibers back and forth over the ground yarn. The weft yarn forms the structure of the reinforcing bottom yarn; a covering cloth surface and a bonding process cover the cloth surface with the reinforcing bottom yarn, and a plurality of the cloth surface, the reinforcing bottom yarn and the non-woven fabric are formed through a needle binding machine. Needle tie points, tightly integrate the cloth surface with the reinforcing bottom yarn.

The advantages obtained by the present invention through the above description are briefly described as follows:

1. The high-strength composite fibers are overlapped with each other in two directions to form a net-like structure, and then a weaving needle machine is used to tightly combine the weft yarn and the bottom yarn to produce a nonwoven structure. Smooth, high structural stability.

2. The strength of the non-woven fabric can be reinforced by the weft yarn for reinforcement, and a cloth surface can be spread on the base yarn with the weft yarn, and then the two are combined by a needle-punching machine, whereby the surface of the non-woven fabric has a beautiful appearance. The pattern, while reinforcing the non-woven structure, provides the advantages of long and durable non-woven fabric.
