[0002] Nonwoven fabric embossing technology is a surface processing technology developed on the basis of nonwoven fabric material forming. It forms specific patterns or functional structures on the surface of nonwoven fabric through mechanical pressure, temperature control or chemical treatment. Nonwoven fabric embossing technology has evolved from the initial aesthetic processing to a key process that integrates functionality and environmental protection. Its core lies in the collaborative innovation of materials, equipment and processes.

[0003] For example, a nonwoven fabric embossing device disclosed in CN201320477718.0 includes a heating device, a smooth roller, and a pattern roller with multiple protruding teeth arranged in a ring on its surface; the pattern roller is located between two ceramic smooth rollers, and the protruding teeth on the pattern roller are hollow protruding teeth; the electric heating rods in the heating device are respectively located inside the hollow protruding teeth. Using the nonwoven fabric embossing device of this utility model to process nonwoven fabric can make the concave and convex boundaries of the pattern clearer and more distinct, with a strong three-dimensional effect, which is not only beautiful but also enhances the pattern retention.

[0004] However, existing nonwoven fabric embossing devices effectively solve the problem of texture presentation; however, since the nonwoven fabric material still needs to undergo further processing to become a usable product after embossing, the pattern retention is still insufficient, and the complex structure of the device makes the processing operation difficult.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0024] Please refer to the following: Figure 1 ,in, Figure 1 A schematic diagram of the structure of a calendering device for imitation bark texture nonwoven fabric provided by this utility model. The calendering device for imitation bark texture nonwoven fabric includes: a first silicone rubber pressure roller 4 and a cooling roller 5;

[0025] A custom embossing roller 6 is provided on one side of the cooling roller 5, and a second silicone rubber pressure roller 7 is provided at the bottom of the custom embossing roller 6.

[0026] Non-woven fabric 2 is positioned on one side of the first silicone rubber pressure roller 4 via a rotating roller. Stone paper 1 is drawn onto the surface of the cooling roller 5. Molten polypropylene mixture 3 is disposed on the bonding surface between the stone paper 1 and the non-woven fabric 2.

[0027] The nonwoven fabric 2 is drawn onto the surface of the first silicone rubber pressure roller 4.

[0028] The stone paper 1 and the nonwoven fabric 2 are pressed together by the molten polypropylene mixture 3 to form a bark-textured nonwoven fabric 8, which is then drawn onto the surface of the customized embossing roller 6 by the cooling roller 5 for printing.

[0029] The cooling roller 5 is hollow inside and has a cooling device. The cooling device inside the cooling roller 5 is a water-cooled circulation system. The cooling roller 5 is equipped with circulating water channels, which are distributed in a spiral or grid pattern to ensure that the cooling water can evenly remove heat. During operation, the cooling water enters from one end of the cooling roller 5, flows in the circulating water channel, absorbs the heat on the surface of the cooling roller 5, and then flows out from the other end, thereby keeping the surface of the cooling roller 5 at a low temperature. This is used to cool and shape the non-woven fabric and stone paper that have undergone lamination, improving the lamination effect and stability. This is a current technology.

[0030] The surface of the custom embossing roller 6 is engraved with a custom bark texture. A heating device is installed inside the roller, which is an electric heating rod distributed along a specific path inside the roller. Powered by an external power source, the heating power is adjustable. During operation, the heat generated by the electric heating rod is evenly transferred to the surface of the roller, raising the surface temperature to a suitable range. This allows for heat printing on the laminated nonwoven fabric, ensuring clearer and more distinct boundaries between the raised and recessed patterns, enhancing the three-dimensional effect and pattern retention. This technology is currently available.

[0031] By adjusting the design pattern and the engraving depth of the customized embossing roller 6, a embossing roller with clear texture and strong three-dimensional effect is produced.

[0032] The working principle of the embossing device for imitation bark texture nonwoven fabric provided by this utility model is as follows:

[0033] During operation, the non-woven fabric 2 and stone paper 1 are first unwound and then laminated through a coating process. The adhesive used for lamination is molten polypropylene mixture 3. The coating process uses a cooling roller 5 and a first silicone rubber pressure roller 4 for pressing. The cooling roller 5 is hollow inside and has a cooling device. The first silicone rubber pressure roller 4 has a hardness of HS80~85 to ensure stable and even pressure.

[0034] The composite nonwoven fabric 2 is processed by a custom embossing roller 6 and a second silicone rubber pressure roller 7. The custom embossing roller 6 has a custom bark texture engraved on its surface and has a heating device inside. The second silicone rubber pressure roller 7 also has a hardness of HS80~85 to ensure stable and even pressure. The composite material after embossing is wound up to make a bark texture nonwoven fabric. Finally, the bark texture nonwoven fabric is made into a bark texture nonwoven bag.

[0035] Compared with related technologies, the embossing device for imitation bark texture nonwoven fabric provided by this utility model has the following beneficial effects:

[0036] This invention provides a embossing device for imitation bark texture nonwoven fabric. By adding an embossing device to the existing nonwoven fabric laminating machine, it effectively solves the problems of weak three-dimensional effect, poor processing stability, and poor pattern retention in nonwoven fabric embossing. Stone paper, which is simple to process, does not easily deform after molding, and has high environmental performance, is selected as the composite material for imitation bark texture nonwoven fabric. Using bark texture for nonwoven fabric printing enhances the visual appeal of the product and has high aesthetic value. It reduces the difficulty of embossing and improves processing stability. The imitation bark texture nonwoven bag has the best three-dimensional effect and strong pattern retention. The pressure on the contact surface of the embossing device is stable and even, resulting in a uniform and consistent pattern effect in the final product. Example

[0037] Please refer to the following: Figure 2and Figure 3 Based on the embossing device for imitation bark texture nonwoven fabric provided in the first embodiment of this application, the second embodiment of this application proposes another imitation bark texture nonwoven bag. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0038] Specifically, the second embodiment of this application provides a non-woven bag with a bark-like texture, which is different in that the non-woven bag with a bark-like texture is made of non-woven fabric with a bark-like texture made by the embossing device of the aforementioned non-woven fabric with a bark-like texture, and also includes: a non-woven bag body 10.

[0039] A pleated collar 11 is disposed on the top of the non-woven bag body 10. Velcro layers 14 are fixedly installed on both the left and right sides of the inner wall of the pleated collar 11. Female buckles 15 are fixedly installed on both the front and back sides of the left and right surfaces of the inner wall of the pleated collar 11. Female buckles 16 are fixedly installed on both the left and right sides of the front and back sides of the inner wall of the pleated collar 11.

[0040] The pleated collar 11 has pleats 12 in the middle of both the front and back sides.

[0041] The outer surface of the pleated collar 11 is provided with a carrying strap 13.

[0042] The surface of the non-woven bag body 10 is a pattern resembling tree bark texture.

[0043] The two hook and loop fastener layers 14 are hook-shaped and plush-shaped on the side closest to each other, so that the two hook and loop fastener layers 14 are glued together when they are attached.

[0044] The male buckle 16 and the female buckle 15 are existing male-female combination buckles.

[0045] The working principle of the non-woven bag with imitation bark texture provided by this utility model is as follows:

[0046] During operation, the sides of the pleated collar 11 are first folded into the inside of the bag through the pleat 12, and the other two sides of the pleated collar 11 are brought close together and glued together. The two layers of Velcro 14 are glued together, and the part that is recessed through the pleat 12 is glued between the two layers of Velcro 14. The sides of the pleated collar 11 are pressed to make the female button 15 and the female button 16 fasten together.

[0047] Compared with related technologies, the non-woven bag with a bark-like texture provided by this utility model has the following beneficial effects:

[0048] This utility model provides a non-woven bag with a bark-like texture. By adding a female buckle 15 and a female buckle 16, the two Velcro layers 14 at the top of the bag are glued together, and the female buckle 15 and the female buckle 16 are fastened together. The pleats 12 cause the pleated collar 11 to be recessed into the bag, so that the pleated collar 11 is glued together on all sides. This avoids the situation where there are large gaps on both sides of the top of the bag when it is glued, maintains the fit of the top of the bag, and avoids the problem of large gaps on the sides of the bag, which could cause the internal items to get wet. This improves the privacy and security of the bag.
