Description

Technical Field

[0001] This utility model relates to the field of flyknit fabric technology, and more specifically, it relates to a breathable multilayer flyknit fabric. Background Technology

[0002] Currently, flyknit fabrics, a new type of fabric made using computer-controlled knitting technology, are widely used in clothing, footwear, and home furnishings due to their lightweight, softness, and ability to achieve complex texture designs. Most existing flyknit fabrics employ a single-layer or few-layer structure, with their breathability and comfort primarily relying on the natural porosity between the yarns. However, in applications such as sportswear or shoe uppers where breathability and cushioning are crucial, simply relying on yarn porosity often fails to meet users' comprehensive needs for rapid heat dissipation, good breathability, and localized shock absorption.

[0003] To improve the breathability and functionality of flyknit fabrics, some technical solutions attempt to improve airflow by increasing openings or splicing breathable fabrics. However, this approach compromises the fabric's integrity, reduces its mechanical strength, and involves complex processing steps, impacting production efficiency. Other solutions incorporate elastic fibers into the yarn to enhance comfort, but this offers limited improvement in breathability and fails to create truly effective airflow channels.

[0004] Therefore, based on the above problems, this application proposes a breathable multilayer flyknit fabric. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a breathable multi-layer flyknit fabric that is woven by first weaving and then dissolving the dissolved yarn, thereby achieving air permeability through the cavity.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A breathable multi-layer flyknit fabric includes an outer layer, a breathable layer attached to the bottom of the outer layer, a woven layer attached to the bottom of the breathable layer, the woven layer being composed of several groups of warp and weft threads, the woven layer being woven in a woven group, the first woven group including a first warp and a first weft, the first warp and the first weft being woven in a warp and weft manner, a support layer attached to the bottom of the woven layer, and a skin-friendly layer attached to the bottom of the support layer.

[0008] The present invention is further configured such that: the weaving group also includes a local support structure formed by the interlacing of dissolving yarns through warp and weft, which is used to form cavities in the fabric.

[0009] The present invention is further configured such that: the dissolving yarn is made of hot melt yarn or water-soluble yarn material, and the dissolving yarn can be removed during the post-processing, thereby forming a hollow cavity at the location of the second weaving group.

[0010] The present invention is further configured such that the outer covering layer is woven from wear-resistant yarn.

[0011] The present invention is further configured such that the support layer is formed of high-strength fiber or mesh structure.

[0012] The present invention is further configured such that the skin-friendly layer is made of a soft fiber material.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. By setting up a multi-layered composite structure consisting of an outer layer, a breathable layer, a woven layer, a support layer, and a skin-friendly layer, the fabric simultaneously possesses abrasion resistance, breathability, structural support, and skin-friendly comfort. Among them, the woven layer introduces different materials through the weaving group to achieve different required weaving structures. By introducing dissolved yarn to form cavities, it achieves the purpose of heat dissipation and breathability, and also has a certain shock absorption effect.

[0015] 2. The dissolved yarn is made of heat-melting yarn or water-soluble yarn material, which is selectively removed through post-processing. This cavity not only significantly improves air circulation and moisture dissipation, achieving efficient heat dissipation, but also provides a certain cushioning and shock absorption effect in local areas, enhancing the softness and comfort when wearing it.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] Example 1, please refer to Figure 1 , Figure 2 The present invention provides the following technical solution:

[0023] This utility model provides a breathable multi-layer flyknit fabric, including an outer layer 1, a breathable layer 2 attached to the bottom of the outer layer 1, a woven layer 3 attached to the bottom of the breathable layer 2, the woven layer 3 being woven by a woven group 31, a support layer 4 attached to the bottom of the woven layer 3, and a skin-friendly layer 5 attached to the bottom of the support layer 4.

[0024] Specifically, the weaving group 31 includes a first warp 311 and a first weft 312. The first warp 311 and the first weft 312 form a stable basic weaving structure through warp and weft interlacing, which is used to ensure the overall strength and uniformity of the fabric.

[0025] The outer layer 1 is woven from abrasion-resistant yarn, giving the fabric surface strong tensile strength and abrasion resistance, making it suitable for use in fields with high abrasion resistance requirements, such as shoe uppers and sports protective gear.

[0026] The breathable layer 2 is a porous structure layer. It can be woven from spacer yarns or hollow yarns, which can form air channels between the outer covering layer 1 and the woven layer 3, enhancing the exchange capacity of air and moisture, thereby avoiding stuffiness.

[0027] The support layer 4 is made of high-strength fibers or formed in a mesh structure, which not only maintains the overall three-dimensional shape of the fabric, but also provides stable support for the formation of local cavities during the weaving process.

[0028] The skin-friendly layer 5 is made of soft fiber material, such as cotton fiber or polyester microfiber, which can directly contact human skin, provide a comfortable touch, and has a certain moisture-wicking capacity, further improving the comfort of wearing.

[0029] Example 2, please refer to Figure 3 In some applications that require greater breathability and cushioning, such as sportswear fabrics, the structure of breathable layer 2 and first warp 311 and first weft 312 alone is not enough to meet the air exchange and shock absorption requirements of high-intensity sports. Therefore, this embodiment is further optimized based on embodiment one.

[0030] Specifically, based on the first warp 311 and the first weft 312 in the weaving group 31, a dissolving yarn 313 is introduced. Compared with the first embodiment, the dissolving yarn 313 replaces a portion of the first weft 312, but the specific weaving method remains unchanged. This allows the first warp 311, the first weft 312, and the dissolving yarn 313 to form a stable basic weaving structure through warp and weft interlacing. After weaving, this structure is in a stable solid state and is used to support and limit the gaps between local yarns.

[0031] The dissolving yarn 313 is interwoven with the first warp 311 or the first weft 312 in a manner that is parallel to the first warp 311 or the first weft 312. During the weaving process, the dissolving yarn 313, the first warp 311 and the first weft 312 together form a three-dimensional support point.

[0032] The dissolving yarn 313 is made of hot-melt yarn or water-soluble yarn, and can be dissolved by soaking in hot water or heating during the post-processing. After the dissolving yarn 313 is removed, a hollow cavity is formed in a local area of ​​the weaving group 31. The cavity not only improves the overall breathability of the fabric, but also provides a certain cushioning and rebound effect when under pressure.

[0033] The specific process steps include:

[0034] 1) Complete the overall weaving of the fabric, in which the outer covering layer 1, the breathable layer 2, the weaving group 31 and the weaving group 31 are formed and bonded in sequence, and the support layer 4 and the skin-friendly layer 5 are also formed simultaneously.

[0035] 2) After the fabric is woven, immerse it in hot water to gradually dissolve the dissolving yarn 313;

[0036] 3) As the dissolved yarn 313 is removed, the local interlacing areas of the braided group 31 lose their filling, thus forming a stable hollow cavity;

[0037] 4) After drying and shaping, the cavity is fixed between the breathable layer 2 and the support layer 4, thereby significantly enhancing the air circulation and cushioning performance of the fabric.

[0038] Example 3, based on Examples 1 and 2, further proposes a modification to the knitting group. Specifically, the dissolved yarns 313 within the knitting group 31 are not uniformly distributed, but rather embedded according to a preset regional distribution. For example, a higher density of dissolved yarns 313 can be arranged in high-heat areas of the sportswear (such as the instep, back, and armpits) to form more and larger cavities after dissolution; while in areas subjected to greater mechanical stress (such as the shoulders and elbows), the distribution of dissolved yarns 313 is reduced, or even only the conventional knitting structure of the first warp 311 and the first weft 312 is retained to maintain strength.

[0039] Different areas correspond to different cavity densities and sizes, allowing the fabric to maintain sufficient strength and support in specific areas while providing better breathability and shock absorption in key heat dissipation areas.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
