Description

Technical Field

[0001] This utility model relates to the field of glass fiber technology, and in particular to a one-step alkali-resistant fiber mesh. Background Technology

[0002] Fiberglass mesh, a widely used reinforcing material in the construction industry, mainly includes two types. One is woven fiberglass mesh fabric, which is woven from fiberglass yarns, usually using a plain weave or interlacing method to form a mesh structure. It has advantages such as high tensile strength, good alkali resistance, flexibility, and high tensile strength in both warp and weft directions. However, its manufacturing process is complex and its production cost is high. The other type is fiberglass mat, which is made by randomly stacking fiberglass filaments or short fibers and bonding them chemically or mechanically. It has excellent chemical corrosion resistance and good thermal insulation properties, but it is brittle, has poor tear resistance and abrasion resistance, and is easily damaged during application.

[0003] Therefore, this invention proposes a one-step alkali-resistant fiber mesh to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a one-step alkali-resistant fiber web, which has excellent tear resistance, impact resistance and abrasion resistance, while having a simple manufacturing process and low production cost.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a one-step alkali-resistant fiber web, the innovation of which is: including a polishing layer and two warp layers respectively disposed on the upper and lower sides of the polishing layer;

[0006] The warp layer includes several warp yarns arranged side by side along the width of the fiber web, and each warp yarn is spread along the length of the fiber web.

[0007] The polishing layer includes several wavy polishing threads arranged sequentially along the length of the fiber web. The wavy polishing threads oscillate back and forth along the width of the fiber web and propagate along the length of the fiber web. Each wavy polishing thread forms a first intersection point with the warp yarns of the two warp yarn layers.

[0008] Furthermore, the adjacent two wavy spun yarns of the plurality of wavy spun yarns are arranged to intersect, and a plurality of second intersection points are formed on both sides of the fiber web width direction.

[0009] Furthermore, at least one warp yarn is arranged on the outer side of the second intersection point on both sides of the fiber web width direction.

[0010] Furthermore, the first and second intersections are bonded together using alkali-resistant adhesive.

[0011] Furthermore, the warp yarns of the two warp layers are arranged alternately or aligned vertically.

[0012] Furthermore, the spacing between adjacent warp yarns in the warp layer is 2~100mm.

[0013] The advantages of this utility model are:

[0014] The one-step alkali-resistant fiber mesh of this invention adopts a sandwich structure, which uses wavy spinning to connect the upper and lower warp yarns to form a whole. It has excellent tear resistance, impact resistance and wear resistance. Moreover, it does not require complicated weaving in the manufacturing process, the manufacturing process is simple and the production cost is low.

[0015] The present invention arranges several wavy warp yarns in an intersecting manner between adjacent wavy warp yarns, thereby increasing the arrangement density of the wavy warp yarns. This not only forms a second intersection point between the wavy warp yarns, but also increases the number of first intersection points between the wavy warp yarns and the warp yarns, making the connection between each layer tighter and thus improving the overall performance of the fiber web.

[0016] This invention arranges at least one warp yarn on the outer side of the second intersection point on both sides of the fiber web width direction, which can effectively improve the tensile strength and tear resistance at the edge of the fiber web.

[0017] In this invention, the wavy polished fibers are bonded together with each other and with the warp yarns using alkali-resistant adhesive, ensuring a firm connection at each intersection. The manufacturing process is simple and the production efficiency is high.

[0018] In this invention, the warp yarns of the two warp layers are arranged alternately or aligned vertically. This can increase the mesh density of the fiber web, increase the number of intersections of the fiber web, improve the overall connection strength of the fiber web, and effectively prevent entanglement between the wavy fiber layers.

[0019] This invention optimizes the warp spacing of each warp layer to ensure that external forces are evenly distributed on the fiber web, avoiding stress concentration and effectively enhancing the tensile strength and tear resistance of the fiber web. Attached Figure Description

[0025] Example 1

[0026] This embodiment provides a one-step alkali-resistant fiber web, such as... Figure 1-3 As shown, it includes a polishing layer C2 and two warp layers C3 and C1 respectively disposed on the upper and lower sides of the polishing layer; each warp layer includes several warp yarns 1 arranged side by side along the width direction of the fiber web, each warp yarn 1 is spread along the length direction of the fiber web, the warp yarns of the two warp layers C3 and C1 are arranged alternately, and the spacing between adjacent warp yarns in each warp layer is 2~100mm; the polishing layer C2 includes several wavy polishing yarns 2 arranged sequentially along the length direction of the fiber web, each wavy polishing yarn 2 oscillates back and forth along the width direction of the fiber web and propagates along the length direction of the fiber web, and each wavy polishing yarn 2 forms a first intersection point a with the warp yarns 1 of the two warp layers C3 and C1.

[0027] In this embodiment, several adjacent wavy filaments 2 are arranged to intersect, forming several second intersection points b1 and b2 on both sides of the fiber web width direction. This design not only enhances the arrangement density of the wavy filaments 2 and forms second intersection points between them, but also increases the number of first intersection points between the wavy filaments 2 and the warp yarns 1, making the connection between layers tighter and thus improving the overall performance of the fiber web. To improve the tensile and tear resistance at the edges of the fiber web, at least one warp yarn is arranged outside the second intersection points b1 and b2 on both sides of the fiber web width direction.

[0028] In this embodiment, the first and second intersections are bonded together with alkali-resistant adhesive, which not only ensures a firm connection at each intersection, but also simplifies the manufacturing process and increases production efficiency.

[0029] This utility model's one-step alkali-resistant fiber mesh adopts a sandwich structure, using wavy polishing to connect the upper and lower warp yarns into a whole, which has excellent tear resistance, impact resistance and wear resistance. Moreover, the manufacturing process does not require complex weaving. Simply arrange the yarns along the conveyor belt in the conveying direction to form the lower warp yarn layer, and then polish the yarns back and forth in a direction perpendicular to the conveying direction to form the polished yarn layer. Then arrange the yarns along the conveying direction to form the upper warp yarn layer, and finally impregnate with glue. Each process can be completed continuously in one go along the conveying direction, the manufacturing process is simple and the production cost is low.
