Description

Technical Field

[0001] This utility model relates to a composite fabric, particularly a triaxial nonwoven multipurpose reinforced composite fabric used in areas such as wall joints or cracks, building waterproofing materials, and road repair. Background Technology

[0002] Existing composite fabrics used for wall joints or cracks, such as the structure disclosed in Chinese Utility Model Patent ZL202120751204.4 entitled "A Steel Wire Composite Fiber Mesh Fabric," include a base frame, a first mounting hole on the front of the base frame, a face frame fixedly connected to the front of the base frame, a second mounting hole on the front of the face frame, a gasket movably connected to the front of the face frame, a screw movably connected to the inner wall of the gasket, warp threads fixedly connected to the back of the face frame, weft threads fixedly connected to the back of the face frame, an X-axis composite tube fixedly connected to the back of the face frame, a Y-axis composite tube fixedly connected to the back of the face frame, and a felt strip fixedly connected to the front of the face frame.

[0003] However, this type of composite fabric has the following two drawbacks in actual production and use: Firstly, because the composite fabric mainly improves its overall deformation resistance through the coordinated use of the backing frame, face frame, X-axis composite tube, Y-axis composite tube, reinforcing thread, and filler, the composite fabric body formed by the warp and weft threads has low deformation resistance, with a tensile strength usually below 200 N / cm. Therefore, when the wall joints or cracks are large, the composite fabric body will still break due to the large force. Secondly, the composite fabric has a complex structure, is heavy, has high production costs, and has a single application. Because fields such as road repair require high tensile strength from the composite fabric, this composite fabric cannot be used in fields such as road repair. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a triaxial nonwoven multipurpose reinforced composite fabric with high tensile strength, which can be better applied to wall joints or cracks, building waterproofing materials and road repair, etc., with wide application, simple structure, light weight and low production cost.

The α angle ranges from 45° to 75°, and the β angle ranges from -45°. °~-75°, the α-angle unidirectional orientation yarn has a count of 34~200tex and a density of 1~5 threads / cm, the β-angle unidirectional orientation yarn has a count of 34~200tex and a density of 1~5 threads / cm, the zero-degree angle unidirectional orientation yarn has a count of 34~200tex and a density of 2~10 threads / cm, the unit area weight of the fourth felt / fabric layer is 15~90 grams / square meter, the first yarn layer, the second yarn layer, the third yarn layer, and the fourth felt / fabric layer are arranged sequentially from top to bottom and are bonded and fixed to form a whole.

[0007] In a preferred embodiment of this utility model, the α-angle unidirectional orientation yarn, the β-angle unidirectional orientation yarn, and the zero-degree angle unidirectional orientation yarn are all glass fiber yarns.

[0008] In a preferred embodiment of this utility model, the first yarn layer is composed of several parallel yarns unidirectionally oriented at 45° to 60°, the second yarn layer is composed of several parallel yarns unidirectionally oriented at -45° to -60°, the 45° to 60° unidirectional yarns have a count of 34 to 120 tex and a density of 1 to 3 yarns / cm, the -45° to -60° unidirectional yarns have a count of 34 to 120 tex and a density of 1 to 3 yarns / cm, the zero-degree angle unidirectional yarns have a count of 34 to 120 tex and a density of 2 to 5 yarns / cm, and the unit area weight of the fourth felt / fabric layer is 15 to 60 grams per square meter.

[0009] In a preferred embodiment of this utility model, the first yarn layer is composed of several parallel yarns unidirectionally oriented at 55° to 75°, the second yarn layer is composed of several parallel yarns unidirectionally oriented at -55° to -75°, the 55° to 75° unidirectional yarns have a count of 120 to 200 tex and a density of 3 to 5 yarns / cm, the -55° to -75° unidirectional yarns have a count of 120 to 200 tex and a density of 3 to 5 yarns / cm, the zero-degree angle unidirectional yarns have a count of 120 to 200 tex and a density of 5 to 10 yarns / cm, and the unit area weight of the fourth felt / fabric layer is 60 to 90 grams per square meter.

The first yarn layer, the second yarn layer, the third yarn layer, and the fourth felt / fabric layer are arranged sequentially from top to bottom and are bonded together to form a whole. This structure offers several advantages. First, the composite fabric of this invention boasts high tensile strength, exceeding 320 N / cm. Therefore, even with large wall joints or cracks, the composite fabric can withstand greater tensile forces, making it less prone to breakage. Furthermore, due to the significantly improved tensile strength, it can be used not only for wall joints or cracks but also for building waterproofing materials and road repair, thus broadening its applications. Second, the composite fabric of this invention exhibits superior tensile strength, elastic modulus, shear strength, and tear resistance compared to existing composite materials. Moreover, the yarns are evenly stressed during operation, reducing breakage and fully utilizing their properties. Finally, the composite fabric of this invention features a simple structure, is lightweight, and has low production costs.

Similarly, the β-angle unidirectional oriented yarns in the second yarn layer are bonded and fixed with adhesive at their intersections to the zero-degree unidirectional oriented yarns in the third yarn layer. Finally, the zero-degree unidirectional oriented yarns in the third yarn layer are bonded and fixed with adhesive at their intersections to the glass fiber mat or nonwoven fabric in the fourth felt / fabric layer. This structure reduces the amount of adhesive used, resulting in a lighter composite fabric and lower production costs.

[0013] The first yarn layer of this composite fabric consists of several parallel yarns unidirectionally oriented at 45° to 60°. The second yarn layer consists of several parallel yarns unidirectionally oriented at -45° to -60°. The 45° to 60° unidirectional yarns have a count of 34 to 120 tex and a density of 1 to 3 yarns / cm. The -45° to -60° unidirectional yarns have a count of 34 to 120 tex and a density of 1 to 3 yarns / cm. The zero-degree angle unidirectional yarns have a count of 34 to 120 tex and a density of 2 to 5 yarns / cm. The weight per unit area of ​​the fourth felt / fabric layer is 15 to 60 grams per square meter. With this structure, the composite fabric of this invention not only has higher tensile strength but also greater bursting force, reaching over 550 N / cm, thus making it better suited for use in building waterproofing materials.

[0014] The first yarn layer of this composite fabric consists of several parallel yarns unidirectionally oriented at 55° to 75°. The second yarn layer consists of several parallel yarns unidirectionally oriented at -55° to -75°. The yarns oriented at 55° to 75° have a count of 120 to 200 tex and a density of 3 to 5 yarns / cm; the yarns oriented at -55° to -75° have a count of 120 to 200 tex and a density of 3 to 5 yarns / cm; the yarns oriented at zero degrees have a count of 120 to 200 tex and a density of 5 to 10 yarns / cm; and the fourth felt / fabric layer has a basis weight of 60 to 90 grams per square meter.
