Description

Technical Field

[0001] The invention relates to the field of non-woven fabrics, in particular to a reinforced polyester non-woven fabric. Background Art

[0002] Polyester non-woven fabric is a kind of fabric that does not require spinning and weaving. It is made by directional or random arrangement of textile short fibers or filaments to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. Non-woven fabrics break through the traditional textile principles and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, and multiple sources of raw materials. It is mainly used in construction and roof waterproofing as the base fabric;

[0003] However, the existing polyester non-woven fabrics have certain shortcomings in use that need to be improved. First, the structure of the non-woven fabrics randomly supported by fiber filaments leads to low overall strength of the non-woven fabrics, which cannot make the non-woven fabrics more tensile-resistant. Secondly, the non-woven fabrics have poor supporting effects, are prone to breakage, and cannot be laid firmly for use. Summary of the invention

[0004] The main purpose of the present invention is to provide a reinforced polyester nonwoven fabric, which can effectively solve the technical problems raised by the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A reinforced polyester non-woven fabric comprises a non-woven fabric top layer, a plurality of reinforcing woven strips are installed inside the non-woven fabric top layer, a symmetrical woven surface structure is installed at the lower end of the non-woven fabric top layer, and a fixed bottom layer is installed at the lower end of the symmetrical woven surface structure.

[0007] As a further solution of the present invention, the symmetrical woven surface structure includes a symmetrical woven top layer and a symmetrical woven bottom layer, the symmetrical woven top layer is installed at the lower end of the non-woven fabric top layer, and the symmetrical woven bottom layer is installed at the lower end of the symmetrical woven top layer.

[0008] As a further solution of the present invention, the fixed bottom layer is fitted and connected to the lower end of the symmetrically woven bottom layer, and the symmetrically woven top layer and the symmetrically woven bottom layer are symmetrically woven and arranged.

[0009] As a further solution of the present invention, the non-woven top layer, the symmetrical woven top layer, the symmetrical woven bottom layer and the fixed bottom layer have the same area and are arranged in sequence from top to bottom.

[0010] As a further solution of the present invention, the reinforcing woven strip passes through the symmetrical woven top layer and the symmetrical woven bottom layer to be connected to the fixed bottom layer, and the non-woven top layer, the symmetrical woven top layer, the symmetrical woven bottom layer and the fixed bottom layer are fixedly connected by adhesion.

[0011] Compared with the prior art, the present invention has the following beneficial effects: through the symmetrical woven surface structure, a symmetrical woven top layer and a symmetrical woven bottom layer are sandwiched between the non-woven top layer and the fixed bottom layer, the symmetrical woven top layer and the symmetrical woven bottom layer are both formed by inclined weaving, and the symmetrical woven top layer and the symmetrical woven bottom layer are symmetrically woven and arranged, and then connected with the non-woven top layer and the fixed bottom layer by thermal bonding, so that the overall strength of the non-woven fabric is increased by the symmetrical woven top layer and the symmetrical woven bottom layer, making the non-woven fabric more tensile-resistant;

[0012] By setting up a non-woven fabric top layer, a reinforced woven strip and a fixed bottom layer, a plurality of reinforced woven strips are set in the non-woven fabric top layer. The reinforced woven strips are formed by weaving and winding, and then pass through the non-woven fabric top layer to be connected with the fixed bottom layer. The reinforced woven strips are laid in the non-woven fabric, which plays a role of firmly connecting and supporting the non-woven fabric, preventing direct breakage of the non-woven fabric when it is torn, and making the non-woven fabric more firmly laid and used.
