Description

Technical Field

[0001] The utility model relates to the technical field of composite non-woven fabrics, in particular to a needled cotton composite non-woven fabric. Background Art

[0002] Composite non-woven fabrics are usually composed of two or more layers of non-woven fabrics made of different materials through physical or chemical methods. Composite non-woven fabrics are a multi-functional material formed by combining different types of non-woven fabric materials or other materials such as films, meshes, knitted fabrics, etc.

[0003] The existing publication number is CN219856262U, and the name is a novel composite non-woven fabric, which includes two non-woven fabric bases, and a filter layer is arranged between the two non-woven fabric bases. A skin-friendly layer is arranged on the side of the inner non-woven fabric base away from the filter layer, and an antibacterial layer is arranged on the side of the outer non-woven fabric base away from the filter layer. An antistatic layer is arranged on the side of the antibacterial layer away from the non-woven fabric base. The antistatic layer, antibacterial layer, non-woven fabric base, filter layer, non-woven fabric base, and skin-friendly layer are stacked in sequence and sewn together by stitches. The antibacterial layer is used to enhance the antibacterial and bacteriostatic performance of the non-woven fabric and maintain an antibacterial effect for a long time. The melt-blown layer is used to block bacteria and avoid infections caused by the failure of the antibacterial layer.

[0004] However, the above non-woven fabric lacks a tensile layer, which results in a relatively small tensile strength of the composite non-woven fabric itself, unable to increase the tensile strength of the non-woven fabric. During later pulling, the non-woven fabric is damaged, resulting in damage to the internal functional fabric layer without protection, affecting the functionality of the non-woven fabric. Content of the Utility Model

[0005] The utility model solves the problems in the related art and provides a needled cotton composite non-woven fabric.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions: A needled cotton composite non-woven fabric includes a filter layer, a purification layer, a tensile layer, a skin-friendly layer, and a decorative cloth. There are two tensile layers, and a filter layer and a purification layer are arranged between the two tensile layers. The filter layer is arranged on the outer side of the two tensile layers towards the inside, and the purification layer is arranged on the inner side of the two tensile layers towards the inside. The skin-friendly layer is arranged on the inner side of the two tensile layers on the outside, and the decorative cloth is arranged on the outside of the two tensile layers on the outside. The tensile layer includes a first tensile line, a second tensile line, and a third tensile line. The first tensile line, the second tensile line, and the third tensile line are horizontally arranged along the X-axis, Y-axis, and Z-axis directions respectively. Multiple threading holes are arranged on the second tensile line and the third tensile line, and the first tensile line passes through the threading holes on the second tensile line and the third tensile line.

[0007] As a preferred embodiment, the first tensile line includes a nylon line and a polyester line. The nylon line is externally wound with the polyester line, and the nylon line and the polyester line are intertwined and woven together.

[0008] As a preferred embodiment, the purification layer includes an inner cotton cloth sleeve and an activated carbon layer. A filling cavity is provided inside the inner cotton cloth sleeve, and the filling cavity of the inner cotton cloth sleeve is filled with the activated carbon layer.

[0009] As a preferred embodiment, the filter layer includes an outer cotton cloth sleeve and filter cotton. A filling cavity is provided inside the outer cotton cloth sleeve, and the filling cavity of the outer cotton cloth sleeve is filled with the filter cotton.

[0010] As a preferred embodiment, both the outer cotton cloth sleeve and the inner cotton cloth sleeve are made of needle-punched cotton.

[0011] As a preferred embodiment, the skin-friendly layer includes a cotton cloth and a porous rubber layer. The porous rubber layer is provided on the inner end face of the cotton cloth, and the porous rubber layer is integrally formed on the inner end face of the cotton cloth.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] It should be noted that the terms used here are only for describing the specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or their combinations.

[0023] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0025] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above-mentioned" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0026] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of differentiating the corresponding components. Without separate declaration, the above words have no special meaning. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model.
