Description

Technical Field

[0001] This utility model relates to the field of fabric technology, specifically to high-strength puncture-resistant composite fabric. Background Technology

[0002] Puncture-resistant composite fabrics include a puncture-resistant layer composed of layers of high-performance puncture-resistant fiber fabrics. While ensuring puncture resistance, they also have a certain degree of flexibility, making them suitable for manufacturing puncture-resistant clothing to be worn on the body.

[0003] Experiments were conducted on the thickness and maximum stab resistance of existing stab-resistant fibers. Data analysis showed that, currently, fabrics made of high-strength fibers such as ultra-high molecular weight polyethylene, while ensuring small fabric thickness and light weight, achieve the best stab resistance effect by stacking multiple layers of fabric. The optimal stab-resistant layer is composed of alternating layers of fine-count plain weave fabric and non-woven fabric.

[0004] However, compared to coats made of ordinary fabrics, this type of composite fabric, which is formed by stacking closely together and then sewn together after being pressed and shaped by a press, has a tight and non-bending stab-proof layer structure. Considering the ease of movement, it is usually only suitable for making sleeveless stab-proof clothing, and it has shortcomings in protecting the arms, especially the elbows.

[0005] To address the aforementioned issues, an alternative technical solution of high-strength puncture-resistant composite fabric is proposed. Utility Model Content

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a high-strength puncture-resistant composite fabric.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength puncture-resistant composite fabric, comprising an inner layer and an outer layer. The inner layer comprises several alternately arranged fine-threaded fabrics and non-woven layers, and the outer layer comprises several alternately arranged interlocking fabrics and non-woven layers. The thickness of the interlocking fabrics decreases unidirectionally toward the inner layer, and the minimum thickness of each interlocking fabric is not less than the thickness of a layer of fine-threaded fabric and a layer of non-woven layer superimposed. The number of layers of the interlocking fabric is greater than the number of layers of the fine-threaded fabric.

[0008] The present invention is further configured such that: the plurality of interlocking fabrics include a first interlocking fabric and a second interlocking fabric divided into several groups, wherein the thickness of the first interlocking fabric and the second interlocking fabric in each group is equal.

[0009] The present invention is further configured such that: the plurality of raised strip structures formed on the surfaces of the first interlocking fabric and the second interlocking fabric are respectively oriented toward both sides of the same nonwoven layer.

[0010] The present invention is further configured such that the thickness of the first interlocking fabric furthest from the innermost layer is not greater than twice the thickness of the second interlocking fabric closest to the innermost layer.

[0011] The present invention is further configured such that: the fine-count fabric is woven into a plain weave structure, and the linear density of the fine-count fabric is 44.4 / tex.

[0012] The present invention is further configured such that the thickness of the fine-count fabric is 0.35-0.45 mm, and the thickness of the nonwoven layer is 0.3-0.4 mm.

[0013] In summary, the present invention has the following beneficial effects: compared with existing puncture-resistant composite fabrics, the further optimization of the stacking method made in this application makes the fabric more flexible when the elbow is bent, and the puncture-resistant effect is applicable to resisting the threat of puncture from the outside to the inside by low-speed, low-energy sharp objects.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] High-strength puncture-resistant composite fabrics, such as Figure 1As shown, the structure includes an inner layer 2 and an outer layer 1. The inner layer 2 includes several alternately arranged fine-threaded fabrics 21 and non-woven layers 3. The outer layer 1 includes several alternately arranged interlocking fabrics and non-woven layers 3. In this embodiment, the fine-threaded fabrics 21 are woven into a plain weave structure. The linear density of the fine-threaded fabrics 21 is 44.4 tex, and the thickness of the fine-threaded fabrics 21 is 0.4 mm. The thickness of the non-woven layers 3 is 0.31 mm. The fine-threaded fabrics 21, non-woven layers 3, and interlocking fabrics are all made of puncture-resistant ultra-high molecular weight polyethylene. They are bonded together with a hot melt adhesive layer. The thickness of the interlocking fabrics decreases unidirectionally towards the inner layer 2. Considering the puncture-resistant properties of the multi-layered fabric, the minimum thickness of the interlocking fabrics is not less than the thickness of a layer of fine-threaded fabric 21 and a layer of non-woven layer 3. The number of layers of the interlocking fabrics is greater than the number of layers of the fine-threaded fabrics 21. The thickness variation is achieved by the variation of the diameter of the ultra-high molecular weight polyethylene fibers.

[0018] To further improve the puncture resistance of the fabric after bending, the interlocking fabric includes a first interlocking fabric 11 and a second interlocking fabric 12 divided into several groups. The thickness of the first interlocking fabric 11 and the second interlocking fabric 12 in each group is equal. The several raised strip structures formed on the surface of the first interlocking fabric 11 and the second interlocking fabric 12 are respectively oriented towards both sides of the same nonwoven layer 3.

[0019] Considering the softness of the fabric, the thickness of the first interlocking fabric 11 furthest from the innermost layer is no more than twice the thickness of the second interlocking fabric 12 closest to the innermost layer. In this embodiment, taking the thickness of the first interlocking fabric 11 furthest from the innermost layer as being equal to twice the thickness of the second interlocking fabric 12 closest to the innermost layer as an example, when the interlocking fabric of the outer layer 1 is set to 9 layers, the fine fabric 21 of the inner layer 2 can be set to 4 layers.

[0020] Since the bending of the elbow causes the inner side of the elbow to bend in the opposite direction to that of the outer layer 1, the sleeve sewn by this embodiment uses two opposite pieces of this embodiment on the inner and outer sides, which are sewn together end to end. Compared with existing puncture-resistant composite fabrics, the further optimization of the stacking method made in this application makes the fabric more flexible when the elbow is bent, and the puncture-resistant effect is applicable to resisting the puncture threat of low-speed, low-energy sharp objects from the outside to the inside.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
