Description

Technical Field

[0001] The utility model belongs to the technical field of medical non-woven fabrics, and in particular relates to a waterproof double-layer medical non-woven fabric. Background Art

[0002] Nonwoven fabrics, also known as non-woven fabrics, are made of oriented or random fibers. They are called cloth because they resemble cloth and have certain properties. They are made by arranging short or random textile fibers to form a web structure, which is then reinforced mechanically, thermally, or chemically. They break through traditional textile principles and offer advantages such as a short process, fast production rates, high yields, low costs, a wide range of applications, and diverse raw material sources.

[0003] A medical breathable non-woven fabric disclosed in Chinese utility model patent publication number CN214983856U has achieved the purpose of improving the breathability of medical non-woven fabrics, allowing medical staff to ventilate and dissipate heat in time when wearing them, improving the wearing experience, and indirectly ensuring the work efficiency of medical staff. However, when using this utility model, it is often necessary to use scissors and other tools to cut it into a better size for different operations according to different practical scenarios. However, this size often requires manual marking and measurement, which is labor-intensive and inconvenient. The two antibacterial layers used in this utility model are attached together. Under normal circumstances, after one antibacterial layer is infected, the other antibacterial layer is also easily infected by the upper antibacterial layer due to the precise fit, which can easily cause the two antibacterial layers to fail quickly. Therefore, a waterproof double-layer medical non-woven fabric is needed to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a waterproof double-layer medical non-woven fabric to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a waterproof double-layer medical non-woven fabric, comprising a first non-woven fabric layer, characterized in that: a breathable waterproof layer is provided on the lower surface of the first non-woven fabric layer, a first antibacterial layer is provided on the lower surface of the breathable waterproof layer, a reinforcing rib layer is provided on the lower surface of the first antibacterial layer, a second antibacterial layer is provided on the lower surface of the reinforcing rib layer, a second non-woven fabric layer is provided on the lower surface of the second antibacterial layer, and grooves are provided on the outer surfaces of the first non-woven fabric layer and the second non-woven fabric layer, and a plurality of ventilation holes are provided on both sides of the inner portion of each groove.

[0006] By arranging a plurality of grooves on the first non-woven fabric layer and the second non-woven fabric layer, when the non-woven fabric needs to be cut as a whole, the non-woven fabric can be conveniently cut to size along the grooves on the first non-woven fabric layer due to the recessed marking lines formed by the grooves, and there is no need to manually measure and position the non-woven fabric for additional marking lines, which helps to cut the non-woven fabric more conveniently and labor-savingly, thereby improving its operational convenience. In addition, since a reinforcing rib layer is provided between the first antibacterial layer and the second antibacterial layer, the first antibacterial layer and the second antibacterial layer are not directly in contact due to the barrier of a certain distance. In this way, when bacteria exist in the upper first antibacterial layer under normal conditions, they will not be directly transmitted to the lower second antibacterial layer, which helps to preserve the bacterial barrier performance of the second antibacterial layer under normal conditions, thereby helping to enhance the double-layer antibacterial effect of the non-woven fabric.

[0007] As a preferred embodiment, each of the vent holes is obliquely arranged in the corresponding groove.

[0008] By arranging each ventilation hole obliquely in the corresponding groove, the connection stability of the first non-woven fabric layer on both sides of the groove can be guaranteed, and the non-woven fabric can be avoided from being easily torn at the ventilation holes and grooves due to local force during use, thereby ensuring the overall structural integrity of the medical non-woven fabric and extending its service life. Secondly, the oblique setting of the oblique ventilation holes can not only provide ventilation but also prevent the ventilation holes from being blocked. Compared with the ventilation holes arranged vertically or horizontally, the oblique ventilation holes are not easily blocked by external dust, fiber fluff or other tiny particles, which helps to ensure the ventilation effect of the non-woven fabric.

[0009] As a preferred embodiment, the cross section of the vent hole is circular.

[0010] As a preferred embodiment, the reinforcing rib layer is made of rubber.

[0011] As a preferred embodiment, a plurality of ventilation grooves are provided on the reinforcing rib layer.

[0012] As a preferred embodiment, the plurality of strips and grooves on the first non-woven fabric layer and the second non-woven fabric layer correspond to each other in the upper and lower parts.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model provides a plurality of grooves on the first non-woven fabric layer and the second non-woven fabric layer. When the non-woven fabric needs to be cut as a whole, the non-woven fabric can be conveniently cut to size along the grooves on the first non-woven fabric layer due to the recessed marking lines formed by the grooves. There is no need to manually measure and position the non-woven fabric for additional marking lines, which helps to cut the non-woven fabric more conveniently and labor-savingly, thereby improving its operational convenience. In addition, since a reinforcing rib layer is provided between the first antibacterial layer and the second antibacterial layer, the first antibacterial layer and the second antibacterial layer are not directly in contact due to the barrier of a certain distance. In this way, when the upper first antibacterial layer has bacteria under normal conditions, it will not be directly transmitted to the lower second antibacterial layer, which helps to preserve the bacterial barrier performance of the second antibacterial layer under normal conditions, thereby helping to enhance the double-layer antibacterial effect of the non-woven fabric.

[0015] The utility model can ensure the connection stability of the first non-woven fabric layer on both sides of the groove by obliquely arranging each ventilation hole in the corresponding groove, and avoid the non-woven fabric from being easily torn at the ventilation holes and the groove due to local force during use, thereby ensuring the overall structural integrity of the medical non-woven fabric and extending its service life. Secondly, the oblique arrangement of the oblique ventilation holes can not only achieve the ventilation effect but also prevent the ventilation holes from being blocked. Compared with the ventilation holes arranged vertically or horizontally, the oblique ventilation holes are not easily blocked by external dust, fiber fluff or other tiny particles, thereby helping to ensure the ventilation effect of the non-woven fabric.

[0026] See also Figure 1-7 The utility model provides a waterproof double-layer medical non-woven fabric, comprising a first non-woven fabric layer 1, a breathable waterproof layer 2 is provided on the lower surface of the first non-woven fabric layer 1, a first antibacterial layer 3 is provided on the lower surface of the breathable waterproof layer 2, a reinforcing rib layer 4 is provided on the lower surface of the first antibacterial layer 3, a second antibacterial layer 5 is provided on the lower surface of the reinforcing rib layer 4, a second non-woven fabric layer 6 is provided on the lower surface of the second antibacterial layer 5, and a groove 7 is provided on the outer surface of the first non-woven fabric layer 1 and the second non-woven fabric layer 6, and a plurality of ventilation holes 8 are provided on both sides of the inner side of each groove 7. By providing a plurality of grooves 7 on the first non-woven fabric layer 1 and the second non-woven fabric layer 6, when the non-woven fabric as a whole needs to be cut, the grooves 7 form a concave The marking lines allow the non-woven fabric to be conveniently cut to size along the grooves 7 on the first non-woven fabric layer 1, without the need for manual additional marking measurement and positioning of the non-woven fabric, thereby facilitating more convenient and labor-saving cutting of the non-woven fabric and improving its operational convenience. In addition, since a reinforcing rib layer 4 is provided between the first antibacterial layer 3 and the second antibacterial layer 5, the first antibacterial layer 3 and the second antibacterial layer 5 are not directly in contact due to a certain distance of obstruction. In this way, when bacteria exist in the upper first antibacterial layer 3 under normal conditions, they will not be directly transmitted to the lower second antibacterial layer 5, thereby helping to preserve the bacterial barrier performance of the second antibacterial layer 5 under normal conditions, thereby helping to enhance the double-layer antibacterial effect of the non-woven fabric.

[0027] Each ventilation hole 8 is obliquely arranged in the corresponding groove 7. By obliquely arranging each ventilation hole 8 in the corresponding groove 7, on the one hand, the connection stability of the first non-woven fabric layer 1 on both sides of the groove 7 can be guaranteed, and the non-woven fabric can be avoided from being easily torn at the ventilation holes 8 and the groove 7 due to local forces such as stretching and bending during use, thereby ensuring the overall structural integrity of the medical non-woven fabric and extending its service life. Secondly, the oblique arrangement of the oblique ventilation holes 8 not only has the effect of ventilation but also can prevent the ventilation holes 8 from being blocked. Compared with the ventilation holes arranged vertically or horizontally, the oblique ventilation holes are not easily blocked by external dust, fiber fluff or other tiny particles, thereby helping to ensure the ventilation effect of the non-woven fabric.

[0028] The cross section of the vent hole 8 is circular.

[0029] The reinforcement layer 4 is made of rubber.

[0030] A plurality of ventilation grooves 9 are provided on the reinforcing rib layer 4 .

[0031] The plurality of grooves 7 on the first non-woven fabric layer 1 and the second non-woven fabric layer 6 correspond to each other in the upper and lower parts.

[0032] The working principle and use process of the present invention are as follows: First, a plurality of grooves 7 are provided on the first non-woven fabric layer 1 and the second non-woven fabric layer 6. When the non-woven fabric needs to be cut as a whole, the recessed marking lines formed by the grooves 7 enable the non-woven fabric to be conveniently cut to size along the grooves 7 on the first non-woven fabric layer 1, without the need for manual additional marking measurement and positioning of the non-woven fabric, thereby facilitating more convenient and labor-saving cutting of the non-woven fabric and improving its operational convenience. In addition, since a reinforcing rib layer 4 is provided between the first antibacterial layer 3 and the second antibacterial layer 5, the first antibacterial layer 3 and the second antibacterial layer 5 are not directly in contact due to the barrier of a certain distance. In this way, when the upper first antibacterial layer 3 contains bacteria in a normal state, It will not be directly transmitted to the second antibacterial layer 5 below, which helps to preserve the bacterial barrier performance of the second antibacterial layer 5 under normal circumstances. In addition, by obliquely arranging each ventilation hole 8 in the corresponding groove 7, on the one hand, the connection stability of the first non-woven fabric layer 1 on both sides of the groove 7 can be guaranteed, and the non-woven fabric can be avoided from being easily torn at the ventilation holes 8 and the groove 7 due to local forces such as stretching and bending during use, thereby ensuring the overall structural integrity of the medical non-woven fabric and extending its service life. Secondly, the oblique setting of the oblique ventilation holes 8 not only has the effect of ventilation but also can prevent the ventilation holes 8 from being blocked. Compared with the ventilation holes arranged vertically or horizontally, the oblique ventilation holes are not easily blocked by external dust, fiber fluff or other tiny particles.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
