Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, and particularly to a wear-resistant composite non-woven fabric. Background Art

[0002] Non-woven fabric, also called non-woven material or non-woven cloth, is made of fibers arranged in a directional or random manner through friction, entanglement, adhesion or a combination of these methods.

[0003] Non-woven fabric has the advantages of light weight, softness, water repellency, breathability, non-toxicity, antibacterial property, etc. Since non-woven fabric is mainly made by entanglement or adhesion of fiber raw materials, the wear resistance and strength of non-woven fabric are poor, and non-woven fabric is easy to crack from the right angle direction.

[0004] Conventional wear-resistant non-woven fabric includes multiple layers, in which a wear-resistant layer covers the entire outer side of the non-woven fabric layer. During use, the wear-resistant layer is in contact with external objects to reduce the risk of the non-woven fabric layer being rubbed, thereby enhancing the wear resistance of the non-woven fabric. At this time, the direct covering of the wear-resistant layer limits the softness and breathability of the composite non-woven fabric to a certain extent.

[0005] Therefore, how to design a non-woven fabric that improves wear resistance while reducing the limitation of softness and breathability has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0006] In order to solve at least one technical problem mentioned in the background art, the purpose of the utility model is to provide a wear-resistant composite non-woven fabric, which improves the wear resistance of the non-woven fabric and minimizes the problem of limited softness and breathability.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A wear-resistant composite non-woven fabric includes a base fabric layer and a non-woven fabric layer. A plurality of wear-resistant protrusions are fixedly arranged on both side surfaces of the base fabric layer. Two groups of non-woven fabric layers are respectively bonded to both sides of the base fabric layer, and the height of the wear-resistant protrusions is greater than the thickness of the non-woven fabric layer.

[0009] Further, the base fabric layer includes warp and weft threads that intersect vertically and horizontally.

[0010] Further, glue layers are arranged on both side surfaces of the base fabric layer, and the wear-resistant protrusions are bonded to the base fabric layer through the glue layers.

[0011] Further, the non-woven fabric layer includes a plurality of needled fibers, and the needled fibers pass through the base fabric layer and are wound and entangled with the non-woven fabric layer on the other side.

[0012] Further, the height of the wear-resistant protrusions is 0.5 mm - 0.7 mm.

[0013] Further, the thickness of the non-woven fabric layer is 0.3 mm - 0.5 mm.

[0014] Further, the thickness of the base fabric layer is 0.5 mm.

[0015] Further, the wear-resistant protrusions are made of one of nylon materials or polyurethane resins.

[0016] Further, the base fabric layer is made of polypropylene fibers.

[0017] Further, nano silver ions are provided inside the base fabric layer.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: by providing a plurality of wear-resistant protrusions higher than the non-woven fabric layer on both side surfaces of the base fabric layer, when the composite non-woven fabric is laid flat, the wear-resistant protrusions are used to contact the external objects, reducing the chance of contact between the non-woven fabric layer and the external objects, thereby reducing the problem that the non-woven fabric layer is prone to wear;

[0019] By installing the non-woven fabric layer on the base fabric layer, the tensile property of the composite non-woven fabric can be improved by utilizing the performance of the base fabric layer itself;

[0020] The non-woven fabric layer still contacts the external air through the gaps between the wear-resistant protrusions, minimizing the impact on the air permeability and softness of the composite non-woven fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] This embodiment provides a wear-resistant composite non-woven fabric, which is mainly used to improve the wear resistance of the non-woven fabric and reduce the influence on air permeability and softness.

[0029] As Figure 1 and Figure 3 shown, it includes a base fabric layer 1, and a number of wear-resistant protrusions 11 are provided on both surfaces of the base fabric layer 1. It also includes non-woven fabric layers 2 on both sides of the base fabric layer 1. Among them, the non-woven fabric layers 2 are both attached to the surface of the base fabric layer 1. As Figure 5 shown, the height of the wear-resistant protrusion 11 is higher than the thickness of the non-woven fabric layer 2.

[0030] In this embodiment, specifically, the height of the wear-resistant protrusion 11 is 0.6 mm, and the thickness of the non-woven fabric layer 2 is 0.4 mm.

[0031] Through the above settings, the non-woven fabric layer 2 is attached to the base fabric layer 1, and the strength of the base fabric layer 1 itself is utilized to improve the tensile performance of the composite non-woven fabric after production. Compared with conventional non-woven fabrics, the composite non-woven fabric has stronger tensile ability, and the right-angle edge position is not easily cracked.

[0032] When the composite non-woven fabric is laid flat, as Figure 5 shown, since the height of the wear-resistant protrusion 11 is higher than the thickness of the non-woven fabric layer 2, among which, the wear-resistant protrusion 11 will first contact the external object, reducing the risk of friction between the non-woven fabric layer 2 and the external object, and thus improving the wear resistance of the composite non-woven fabric.

[0033] During the use of the composite non-woven fabric, the composite non-woven fabric can usually be bent, and the bending position is at the gap between the wear-resistant protrusions 11. At this time, the non-woven fabric layer 2 can be exposed at the bending place; it should be noted that whether the composite non-woven fabric is in a flat state or a bent state, the non-woven fabric layer 2 will be exposed to the air at this time, so as not to affect the air permeability of the composite non-woven fabric.

[0034] In order to install the wear-resistant protrusion 11, in this embodiment, as Figure 5 shown, glue layers 3 are coated on both sides of the base fabric layer 1. Among them, the wear-resistant protrusions 11 are fixedly installed on the base fabric layer 1 through the glue layers 3.

[0035] Specifically, the wear-resistant protrusions 11 can be made of nylon material or polyurethane resin. In this embodiment, the wear-resistant protrusions 11 are prepared from nylon material.

[0036] Since the surface of the base fabric layer 1 is coated with an adhesive layer 3, as Figure 5 shown, at this time, the non-woven fabric layer 2 can be adhered to the base fabric layer 1, improving the firmness of the non-woven fabric layer 2.

[0037] In order to improve the tensile strength of the composite non-woven fabric, in this embodiment, as Figure 1 、 Figure 4 and Figure 5 shown, the base fabric layer 1 is woven from warp and weft threads. Among them, the base fabric layer 1 is made of polypropylene fibers.

[0038] The thickness of the base fabric layer 1 is 0.5 mm.

[0039] In order to further enhance the connection strength between the non-woven fabric layer 2 and the base fabric layer 1 and reduce the risk of the non-woven fabric layer 2 being torn off from the base fabric layer 1, in this embodiment, the non-woven fabric layer 2 is made by needling or hydroentangling processes. There are several needled fibers 21 on the non-woven fabric layer 2. Among them, the needled fibers 21 on the non-woven fabric layer 2 pass through the base fabric layer 1 and embrace each other with the non-woven fabric layer 2 on the other side, as Figure 2 and Figure 5 shown. At this time, the non-woven fabric layers 2 on both sides of the base fabric layer 1 are intertwined with each other through the needled fibers 21, further strengthening the strength of the composite non-woven fabric and reducing the risk of the non-woven fabric being torn.

[0040] Among them, nano silver ions are added to the base fabric layer 1, so that the prepared composite non-woven fabric has good antibacterial properties.

[0041] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
