Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and in particular to an impact-resistant fabric. Background Technology

[0002] Impact-resistant fabrics are used in many fields, especially in personal protection, where they play a vital role by absorbing excess impact force to protect the human body from injury. With advancements in technology and rising living standards, people increasingly expect impact-resistant fabrics to offer not only impact protection but also better softness, breathability, and lightweight properties.

[0003] Existing impact-resistant uppers are mostly formed by laminating fabric with other materials. See patent publication number CN215649521U for an air-cushioned upper, which discloses a bottom film and an upper film. The edges of the bottom film and the upper film are bonded together to form a sealing edge, and gas is filled between the bottom film and the upper film to form an air bladder. The sealing edge is used to connect to the outer shoe body. Although this structure, which forms an air bladder by filling the space between the bottom film and the upper film, is simple and makes the upper lightweight, the bottom film and the upper film, and the gas filling space between them, are not breathable. Therefore, the upper is not breathable at the bottom film and the upper film, which in turn affects the overall breathability of the fabric and reduces its softness. Furthermore, the bonding of the edges of the bottom film and the upper film to form the sealing edge, which is used to connect to the outer shoe body, requires multiple processes, each with a certain degree of complexity. In addition, during use, the sealing edge may be affected by wear, tear, or aging, causing the air bladder to fail and the fabric to lose its impact-resistant function. Utility Model Content

[0004] Therefore, there is a need to provide an impact-resistant fabric that can solve the problem of poor breathability of existing impact-resistant fabrics.

[0005] To achieve the above objectives, this utility model provides an impact-resistant fabric, the fabric including a raised area, the raised area including a raised portion raised in a non-horizontal direction and a cavity formed in the raised portion; the cavity has a filling material.

[0006] Furthermore, the raised portion is a localized area of ​​the raised region.

[0007] Furthermore, the projection of the raised portion in the height direction has a regular shape.

[0008] Furthermore, the number of weaves gradually increases from the starting weave to the middle weave of the raised area, and gradually decreases from the middle weave to the ending weave, wherein the number of weaves in the starting weave and the ending weave are equal, so that the raised area has a raised portion.

[0009] Furthermore, the filler is formed by winding yarn.

[0010] Furthermore, the filler is integrally woven into the raised area.

[0011] Furthermore, the raised areas are numerous and distributed in a staggered manner.

[0012] Furthermore, the raised portions of several of the raised regions have the same raised direction.

[0013] Furthermore, the fabric also includes a connecting area, through which several of the raised areas are connected.

[0014] Furthermore, the fabric is integrally woven into shape.

[0015] Unlike existing technologies, the above technical solution features a raised area, which includes a raised portion containing a cavity. When subjected to external impact, the raised portion and its internal cavity structure deform, generating stress that effectively absorbs and disperses impact energy. When the external force is removed, the stress causes the edges of the cavity to elastically recover, restoring the cavity to its original shape. By placing filler within the cavity, the raised portion absorbs energy more gently upon impact, effectively reducing the impact felt by the wearer and improving comfort, especially in personal protective equipment applications. This impact-resistant fabric does not require bonding with other materials and possesses excellent softness, breathability, and lightweight properties. Attached Figure Description

[0032] See Figure 1 and Figure 2 As shown, this utility model provides an impact-resistant fabric. By providing a raised area 10, which includes a raised portion 101 and a cavity 102 within the raised portion 101, the structure of the raised portion 101 and its internal cavity 102 deforms and generates stress when subjected to external impact, effectively absorbing and dispersing impact energy. When the external force is removed, the stress causes the sides of the cavity to elastically recover, thus restoring the cavity to its original shape. By providing a filler 30 within the cavity 102, the raised portion 101 can absorb energy more gently when impacted, especially in personal protective applications, effectively reducing the impact felt by the wearer and improving wearing comfort. This impact-resistant fabric does not require bonding with other materials and possesses good softness, breathability, and lightweight properties.

[0033] The following provides an embodiment of an impact-resistant fabric of the present invention. The fabric includes a raised area 10, the raised area 10 including a raised portion 101 raised in a non-horizontal direction and a cavity 102 formed in the raised portion 101; the cavity 102 has a filler 30 inside.

[0034] The aforementioned raised portion 101 along a non-horizontal direction refers to a raised portion 101 having an angle relative to its outer periphery (non-raised portion 101), such that the raised portion 101 is inclined or perpendicular to its outer periphery. The shape of the raised portion 101 is not limited. The raised portion 101 can be raised along a point in the raised area 10, such as a tetrahedral raised portion 101 or a hemispherical raised portion 101; the raised portion 101 can also be raised along a local area of ​​the raised area 10, and the local area can be a plane, a curved surface, or a combination of multiple surfaces, such as a regular hexahedron or a regular octahedron raised portion 101. It should be noted that the aforementioned point or local area can be located anywhere on the raised area 10. The projection of the raised portion 101 in the height direction can be regular or irregular in shape, and the regular shape can include, but is not limited to, polygons, circles, and near-circular shapes. The size of the raised portion 101 is not limited, and the size of the raised portion 101 can be designed according to the size of the impact-resistant fabric and the impact-resistant function requirements.

[0035] There are various embodiments in which the raised portion 101 has a cavity 102. In some embodiments, the raised portion 101 can be formed by splicing together multiple fabrics. In some embodiments, the raised area 10 of the raised portion 101 is twisted after being connected at certain positions on the outer periphery of the raised portion 101, so that the raised area 10 has a raised portion 101 that bulges in a non-horizontal direction and a cavity 102 formed in the raised portion 101; specifically, the two ends on one side of the connection of the raised portion 101 can be cross-woven with the corresponding side on the outer periphery of the raised portion 101 to twist and form a raised portion 101 with a cavity 102. In some embodiments, the number of weaves gradually increases from the starting weave to the middle weave of the raised area 10, and gradually decreases from the middle weave to the ending weave, wherein the number of weaves in the starting weave and the ending weave are equal, so that the raised area 10 has a raised portion 101. The middle weave refers to the weave containing a specific point or local area of ​​the raised portion 101, i.e., the weave between the outer perimeter of the raised portion 101 and the maximum height difference of the raised portion 101. The number of weave rows gradually increases from the initial weave row to the middle weave row, and gradually decreases from the middle weave row to the final weave row, causing the raised portion 101 to rise. The increase and decrease of weave rows can be achieved by adding one or more rows every few rows, or by increasing them according to a certain proportion or pattern, depending on the desired degree of elevation and the overall design of the shape of the raised portion 101. The number of weave rows at the beginning and end of the weave rows is set to be equal to avoid unnecessary twisting or deformation of the fabric in the raised portion 10.

[0036] The aforementioned filling material 30 allows the raised portion 101 to absorb energy more gently upon impact, effectively reducing the impact sensation. The filling material 30 can be polyester fiber, natural fibers (such as coconut fiber, mountain palm fiber, etc.), down, or feathers. Preferably, the filling material 30 is formed by yarn winding. Yarn winding can create a multi-layered support structure, allowing the filling material 30 to evenly distribute pressure when compressed, reducing discomfort from single-point pressure, while better maintaining its shape and stability, providing a lasting support effect. Simultaneously, the yarn-wound filling material 30 can be integrally woven with the raised portion 101. Specifically, during the weaving of the raised portion 101, some yarns are not looped, forming floats that are wound within the cavity 102 to fill it, creating a tight bond between the yarn-wound filling material 30 and the raised portion 101, preventing displacement or deformation. The yarn can be selected with a high F (filament) number. F represents the number of fine fibers in a single synthetic fiber, which can also be understood as the number of plies in a warp or weft yarn. The higher the F number, the more fine fibers the synthetic fiber is composed of, and the softer and fluffier the fabric usually feels. The filling formed by winding high-F yarn is softer, can absorb energy more gently, and can effectively reduce the impact.

[0037] To distribute the effects of external forces and enhance the cushioning effect of the shoe material, several raised areas 10 are typically incorporated within the shoe material. These raised areas 10 have their raised portions 101 sharing the impact of the external force, thus increasing the cushioning effect of the fabric, reducing the impact of the external force, and achieving better impact resistance. The shape and size of the raised portions 101 in the several raised areas 10 can be partially the same, all the same, partially different, or completely different. Preferably, the raised portions 101 in the several raised areas 10 have the same shape and size, ensuring that the cushioning effect per unit area within the impact-resistant fabric is uniform when subjected to external forces. Preferably, the raised areas 10 are arranged closely together, meaning that when the fabric is impacted, at least one raised portion 101 provides cushioning, ensuring that every part of the fabric provides impact resistance. The raised areas 10 can be arranged in a straight line or in a staggered arrangement.

[0038] The bulge directions of the bulges 101 in the several bulge regions 10 may be the same or different. When the bulge directions of the bulges 101 in the several bulge regions 10 are the same, each bulge 101 can form a unified force direction when subjected to external forces, thereby enhancing the stability of the overall structure, more effectively dispersing and resisting external forces, and reducing the risk of structural deformation or damage; at the same time, it helps to reduce stress concentration, and the stress can be more evenly distributed on each bulge 101, thereby reducing the risk of stress concentration and improving the durability of the overall structure.

[0039] The fabric also includes connecting areas 20, through which several raised areas 10 are connected. The connecting areas 20 act as connecting ribs between the raised areas 10, ensuring that each raised area 10 forms a unified whole under stress, collectively resisting external forces, thereby improving the stability and load-bearing capacity of the entire structure. In some embodiments, the raised areas 10 and connecting areas 20 are woven separately and then spliced ​​together to form the impact-resistant fabric; this method is simple and easy to implement. In some embodiments, the raised areas 10 and connecting areas 20 are woven integrally to form the impact-resistant shoe material fabric, which can be obtained without splicing, reducing labor costs.

[0040] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
