[0030] According to a first aspect of this utility model, this embodiment discloses a brush fabric, such as... Figure 1 As shown, it may include:

[0031] The base fabric layer 01, the first adhesive layer 04, the second adhesive layer 06, the third adhesive layer, and the fleece layer 03;

[0032] The first adhesive layer 04 is bonded to the first fabric surface of the base fabric layer 01, the velvet layer 03 is woven on the second fabric surface of the base fabric, the first fabric surface and the second fabric surface are opposite to each other, the second adhesive layer 06 is bonded to the second fabric surface of the base fabric layer 01, and the second adhesive layer 06 is bonded to the part of the velvet layer 03 near the base fabric layer 01.

[0033] The base fabric layer 01 has a first through hole 02. The third adhesive layer is bonded to the wall of the first through hole 02. The first adhesive layer 04 is bonded to one end of the third adhesive layer. The first adhesive layer 04 and the third adhesive layer are connected to form a second through hole 05. The second adhesive layer 06 is bonded to the other end of the third adhesive layer. The first through hole 02 and the second through hole 05 are connected.

[0034] In this embodiment, as Figure 1 As shown, by setting the first adhesive layer 04, the second adhesive layer 06, and the third adhesive layer to be bonded to the base layer, the velvet layer 03 is more firmly connected to the base fabric layer 01, ensuring the stability of the velvet layer 03's connection to the base fabric layer 01, thereby reducing the problem of velvet shedding during brush use. By bonding the second adhesive layer 06 to the part of the velvet layer 03 near the base fabric layer 01, not only is the velvet layer 03 firmly connected to the base fabric layer 01, but the area where the second adhesive layer is bonded to the velvet layer 03 is also reduced, that is, the rough surface on the velvet filaments 31 of the velvet layer 03 is reduced, ensuring the fluidity of the paste when the velvet layer 03 is subsequently applied. The first through hole 02 and the second through hole 05 are connected to facilitate the flow of steam generated by the hot melt adhesive when the brush fabric 100 is bonded to the substrate to form a brush. This prevents the steam generated by the hot melt adhesive from not being able to flow out in time between the fabric and the substrate, which could cause cavities in the fabric and lead to difficulties in bonding the fabric to the substrate or a weak bond.

[0035] According to one embodiment of the present invention, such as Figure 1 As shown, the first adhesive layer 04 is formed by coating the first fabric surface of the base fabric layer 01 with adhesive, the adhesive flows into the first through hole 02 to form a third adhesive layer, and the adhesive flows through the first through hole 02 to the second fabric surface and contacts the velvet layer 03 to form a second adhesive layer 06.

[0036] In this embodiment, the second adhesive layer 06 and the third adhesive layer are formed by the flow of adhesive when the first adhesive layer 04 is applied. The adhesive applied to the first fabric surface is the first adhesive layer 04. The adhesive flowing from the first fabric surface into the first through hole 02 is the third adhesive layer located on the wall of the first through hole 02. The adhesive flowing from the first through hole 02 to the second fabric surface of the base fabric layer 01 is the second adhesive layer 06. This ensures that the first adhesive layer 04, the second adhesive layer 06, and the third adhesive layer have a direct connection, ensuring the stability of the connection between the three adhesive layers, thereby ensuring the stability of the flock layer 03 connected to the base fabric layer 01. The second through hole 05 is formed on the first adhesive layer 04 after the adhesive on the first adhesive layer 04 flows into the first through hole 02, resulting in a state where the second through hole 05 is connected to the first through hole 02.

[0037] In some embodiments, the second adhesive layer 06 is connected to the third adhesive layer to form a third through hole. Specifically, the adhesive of the third adhesive layer on the first through hole 02 flows along the hole wall of the first through hole 02 to the second fabric surface of the base fabric layer 01, and then forms the second adhesive layer 06 on the second fabric surface. The part of the second adhesive layer 06 located in the first through hole 02 is in a through hole state, and the through hole is the third through hole of the second adhesive layer 06.

[0038] In some embodiments, the first adhesive layer uniformly covers the first fabric surface of the base fabric, and the thickness of the first adhesive layer is basically consistent. The second adhesive layer is distributed in a dispersed state on the second fabric surface of the base fabric. The adhesive layer thickness of the filaments 31 that are at least partially close to the filament layer 03 is greater than the adhesive layer thickness of the filaments 31 that are far away from the filament layer 03, further ensuring the stability of the filament layer 03 connected to the base fabric layer 01.

[0039] In some embodiments, the thickness of the second adhesive layer 06 near the first through hole 02 is greater than the thickness of the second adhesive layer 06 away from the first through hole 02.

[0040] According to one embodiment of the present invention, such as Figure 1 As shown, the diameter of the first through hole 02 ranges from 0.5 to 1.5 mm, and the spacing between adjacent first through holes 02 ranges from 0.5 to 1.5 mm.

[0041] In this embodiment, the aperture of the first through hole 02 is designed to facilitate the flow of adhesive from the first fabric surface to the second fabric surface when the adhesive is applied to the first fabric surface. It also facilitates the flow of steam generated by the hot melt adhesive when the brush fabric 100 is bonded to the substrate to form a brush. In addition, the aperture of the first through hole 02 and the spacing between adjacent holes are designed to ensure the number of filaments 31 of the filament layer 03 that can be connected to the second fabric surface of the base fabric.

[0042] According to one embodiment of the present invention, such as Figure 2 As shown, the filament layer 03 includes bundles of filaments 311, and each bundle of filaments 311 includes a single filament 3111, such as... Figure 3 As shown, the monofilament 3111 is woven into the base fabric layer 01 to form a velvet layer 03, or the bundle filament 311 includes m monofilaments 3111, where m is a natural number, 2≤m≤6, and the m monofilaments 3111 are intertwined and woven together to form the bundle filament 311. The bundle filament 311 is woven into the base fabric layer 01 to form a velvet layer 03, and the second adhesive layer 06 on the second fabric surface is bonded to the monofilament 3111.

[0043] In this embodiment, the single monofilament 3111 serves as the bundle filament 311, and can be twisted and warped using a general-purpose twisting machine at approximately 80 twists per meter. In this embodiment, the monofilament 3111 or the bundle filament 311 does not require covering, reducing the weaving process.

[0044] Preferably, the crimp of the monofilament 3111 is ≥70%.

[0045] According to one embodiment of the present invention, such as Figure 2 As shown, the velvet layer 03 also includes elastic filaments 312. The elastic filaments 312 are wrapped around the outer periphery of the bundle filaments 311 along the length direction of the bundle filaments 311 to form velvet 31, or the elastic filaments 312 are wrapped around the outer periphery of the monofilaments 3111 along the length direction of the monofilaments 3111 to form velvet 31. The velvet filaments 31 are woven into the base fabric layer 01 to form the velvet layer 03. The second adhesive layer 06 on the second fabric surface is bonded by the elastic filaments 312.

[0046] In this embodiment, the method of forming filaments 31 by wrapping bundled filaments 311 with elastic yarns 312 makes the filaments 31 easy to weave and ensures that the filament layer 03 formed by the filaments 31 on the base fabric has a tight and non-loose structure, which has a good adsorption effect on the sizing agent in subsequent work, reducing the number of times the filaments stick to the brush and increasing the area that can be coated after the brush has been coated once. Furthermore, it increases the firmness of the filaments 31 attached to the base fabric layer 01, preventing the brush from shedding filaments.

[0047] In some embodiments, the elastic yarn 312 and the monofilament 3111 are made of polypropylene, polyester, nylon or polypropylene, and the base fabric layer 01 is made of polyester.

[0048] In some embodiments, the low-elasticity yarn 312 includes, but is not limited to, heavy-duty low-elasticity yarn.

[0049] According to one embodiment of the present invention, such as Figure 2 As shown, the bundle filament 311 includes m monofilaments 3111, where m is a natural number, 2≤m≤6, and the m monofilaments 3111 are intertwined and woven together to form the bundle filament 311.

[0050] In this embodiment, the structural stability of the bundle 311 is improved by winding and weaving multiple monofilaments 3111 to form a bundle 311. The appropriate number of monofilaments 3111 can be selected according to the required thickness of the bundle 311, making the manufacturing of the bundle 311 simple and easy to obtain.

[0051] According to one embodiment of the present invention, the denier of the monofilament 3111 is 200D-600D, and the denier of the elastic filament 312 is 75D-150D.

[0052] In this embodiment, a suitable number of denier (D) for monofilament 3111 and elastic filament 312 can be selected according to the required softness and hardness. The D of elastic filament 312 is smaller than that of monofilament 3111, which makes it easier to wrap multiple monofilaments 3111 with elastic filament 312 to form bundles of filament 311. It also makes it easier for the adhesive to flow to the fabric surface with bundles of filament 311. When the hot adhesive releases heat during the solidification process, the elastic filament 312 shrinks, resulting in better adhesion between the elastic filament 312 and the adhesive.

[0053] According to one embodiment of the present invention, the cross-sectional shape of the monofilament 3111 includes a circle, a triangle, an ellipse, a rectangle, or a polygon.

[0054] In this embodiment, a monofilament 3111 with selectable cross-sectional shapes is provided.

[0055] According to one embodiment of the present invention, the monofilament 3111 is a strip-shaped rod or a rod with branches on the main stem, and the rod is wavy or spiral.

[0056] In this embodiment, the strip-shaped monofilaments 3111 facilitate better flow of the slurry on the brush when it adheres to it. The branched branches on the main stem of the monofilaments 3111 further enhance the brush's ability to coat the slurry. The wavy or spiral shape of the rod improves both the brush's coating effect and its overall application.

[0057] According to one embodiment of the present invention, the colors of the bundle filaments 311 and the elastic filaments 312 include black, gray, white, red or blue, and the base fabric may or may not be the same color as the bundle filaments 311.

[0058] In this embodiment, the appearance of the brush fabric 100 is improved.

[0059] According to the second aspect of this utility model, this embodiment discloses a roller brush, such as... Figure 4 As shown, it includes the brush fabric 100, the fourth adhesive layer 200, and the cylinder 300 as described above;

[0060] The fourth adhesive layer 200 is bonded to the outer peripheral surface of the cylinder 300, and the first fabric surface of the brush fabric 100 is bonded to the fourth adhesive layer 200 through the first adhesive layer 04.

[0061] In this embodiment, a roller brush is provided, which is constructed by the brush fabric 100, the fourth adhesive layer 200, and the cylinder 300. The stability of the brush fabric 100 attached to the cylinder 300 is improved by bonding the first fabric surface of the brush fabric 100 to the fourth adhesive layer 200 through the first adhesive layer 04. The substrate mentioned above includes, but is not limited to, the cylinder 300 of this embodiment.

[0062] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
