Abstract

This invention discloses a multidimensional moisture-wicking and breathable composite fabric and its preparation method, comprising an inner lining and an outer layer. The inner and outer layers are connected by stitching or bonding to form linear or cross-connected areas. These areas accommodate moisture-wicking elements, which are in contact with the flow-guiding elements. Flow-guiding elements located between the inner lining and the outer layer are perpendicularly contacting and staggered with the moisture-wicking elements, which absorb and guide moisture into the moisture-wicking elements. This multidimensional moisture-wicking and breathable composite fabric and its preparation method redesign the moisture-wicking structure between the inner and outer layers.

Simultaneously, it utilizes moisture wicking and absorption to guide simple deformation of the fabric and achieve an auxiliary rapid drying effect, resulting in better performance.

Description

Technical Field

[0001] This invention relates to the field of composite fabric technology, specifically to a multidimensional moisture-wicking and breathable composite fabric and its preparation method. Background Technology

[0002] Multi-layered fabrics have a wider range of uses and more functions, such as anti-static or waterproof properties. When made into garments, these fabrics can also provide a better wearing experience and adapt to some special environmental requirements.

[0003] A moisture-wicking polyester fabric, with publication number CN219256717U, relates to the field of textile technology and aims to solve the problem of difficult-to-clean oil stains on woven placemats. The key technical points are: it includes an outer layer and an inner layer; the outer layer surface has an array of several moisture-wicking holes (first type), and the inner layer surface has an array of several moisture-wicking holes (second type); several absorbent cloths that block the second moisture-wicking holes are bonded between the outer and inner layers, forming a moisture-wicking cavity between the outer and inner layers; the first moisture-wicking holes communicate with the moisture-wicking cavity; and moisture-wicking protrusions are integrally formed within the moisture-wicking cavity, with the guiding surfaces of the protrusions facing the absorbent cloths on both sides. This utility model's moisture-wicking polyester fabric achieves the technical effect of moisture wicking and oil removal by using polypropylene fibers and viscose fibers.

[0004] And a moisture-wicking and antibacterial nylon fabric disclosed in the prior art (CN218558220U) includes a nylon base fabric and multiple moisture-wicking and antibacterial units disposed on the nylon base fabric. Each moisture-wicking and antibacterial unit includes an inner antibacterial fiber fabric and an outer antibacterial fiber fabric respectively disposed on both sides of the nylon base fabric. Multiple moisture-wicking cotton threads are fixedly connected to the inner antibacterial fiber fabric, and these threads pass through the nylon base fabric and the outer antibacterial fiber fabric. This moisture-wicking and antibacterial nylon fabric, by setting multiple moisture-wicking and antibacterial units on the nylon base fabric, effectively improves the overall moisture-wicking and antibacterial properties of the fabric.

[0005] The aforementioned existing technologies have all made many improvements to traditional fabrics and also have the same moisture-wicking effect. However, they still have some drawbacks. Because the moisture-wicking fibers or threads are located between the double / multi-layer structure of the fabric, even if the moisture-wicking effect can be achieved, it is only to transfer moisture from one area of ​​the fabric to another area. Furthermore, the moisture between the inner and outer layers is not isolated, resulting in poor wearing comfort when such fabrics are used as clothing materials in special environments. Summary of the Invention

[0006] The purpose of this invention is to provide a multidimensional moisture-wicking and breathable composite fabric and its preparation method, in order to solve the problem mentioned in the background art that the fibers or threads used for moisture wicking in the prior art are located between the double / multi-layer structure of the fabric. Even if the moisture wicking effect can be achieved, it is only to transfer moisture from one area of ​​the fabric to another area, and the moisture between the inner and outer layers is not isolated. As a result, when such fabrics are used as clothing materials, the wearing experience is not good in special environments.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-dimensional moisture-wicking and breathable composite fabric and its preparation method, comprising an inner lining and an outer layer, wherein the inner and outer layers are connected in a linear or cross-shaped manner by stitching or bonding, and the areas are used to accommodate moisture-wicking elements, wherein the moisture-wicking elements are in contact with the flow-guiding elements, and the flow-guiding elements located between the inner lining and the outer layer are in perpendicular contact with the moisture-wicking elements and are staggered, and the flow-guiding elements are used to absorb moisture and guide it into the moisture-wicking elements.

[0008] As a further step, the flow guide includes uniformly distributed flow lines.

[0009] As a further step, the upper end face of the guide line is attached to the inner surface of the outer layer.

[0010] Furthermore, the lower end face of the guide line is attached to the upper surface of the moisture-wicking component.

[0011] As a further step, the moisture-wicking element includes a flexible strip of non-absorbent material, wherein the upper end face of the flexible strip is a concave arc-shaped guiding surface.

[0012] As a further step, the guiding surface is used to collect moisture in the guide line and form a guide structure.

[0013] As a further step, the guide line above the flexible strip is disconnected.

[0014] As a further step, the moisture-wicking element is a water-absorbing line, and the lower end face of the water-absorbing line is attached to the upper surface of the waterproof membrane, which is attached to the inner surface of the liner.

[0015] As a further step, the guide line above the absorbent line is non-disconnected, and the absorbent line is used to expand after absorbing water and separate the inner lining and the outer layer.

[0016] As a further step, the outer layer has a breathable slit located on the side of the water absorption line on its surface.

[0017] As a further step, the outer layer is made of an elastic material, wherein the vent seam is pulled open to form a vent hole after the water absorption line absorbs water and expands.

[0018] The fabric preparation method includes the following steps:

[0019] Step 1: Pre-treatment of the inner lining side: The hot press laminating machine applies the waterproof membrane to the inner surface of the lining by hot pressing. The water absorption line is positioned according to the design spacing using a precision dispensing machine / hot air bonding machine, and the lower end is hot-pressed and bonded to the upper surface of the waterproof membrane.

[0020] Step 2: Pre-treatment of the outer layer: Laser-cut the pre-set ventilation seams on the outer layer surface, and evenly lay the guide lines on the inner surface of the outer layer in an interlaced grid, and initially fix them with a small amount of hot melt adhesive;

[0021] Step 3: Outer and Inner Layer Composite: The pre-treated inner lining and outer layer are precisely aligned and overlapped. Linear / cross-connection areas are formed at predetermined positions by sewing or applying adhesive. The connection area extends through the outer and inner layers, fixing them locally. The non-connection area forms a channel to accommodate the absorbent lines, ensuring that the absorbent lines are in contact with the guide lines. The composite structure is then subjected to low-temperature hot pressing to strengthen the interlayer adhesion.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the multidimensional moisture-wicking and breathable composite fabric and its preparation method redesign the moisture-wicking structure between the inner and outer layers, which can absorb and wick moisture from multiple dimensions on the one hand, and avoid the inner lining of the fabric being affected too much on the other hand. At the same time, it can use moisture wicking and water absorption to guide the fabric to undergo simple deformation and achieve the effect of assisting rapid drying, resulting in better performance, as shown in the following details.

[0023] 1. Densely distributed guide lines are used to contact the outer layer, thereby uniformly and quickly absorbing the moisture absorbed by the outer layer. Through the full contact between the guide lines and the moisture-wicking components, secondary transfer of moisture is achieved, thus preventing the moisture from being reabsorbed by the inner lining and affecting the drying effect of the inner layer of the fabric.

[0024] Furthermore, the moisture-wicking component is designed as an elastic flexible strip structure, which on the one hand can enhance the overall structural strength of the fabric, and on the other hand can use its arc-shaped guide surface to effectively collect and drain moisture, thereby achieving a better moisture-wicking effect.

[0025] 2. Using absorbent threads instead of moisture-wicking components can improve the integrity of the fabric and achieve better moisture-wicking function by utilizing their good absorbency.

[0026] At the same time, it can also use its water absorption and rapid expansion characteristics to separate the outer layer and the inner lining by a certain distance. On the one hand, it can prevent the inner lining from being excessively affected by moisture. On the other hand, it can form multiple ventilation channels with the expanded space and ventilation seams, thereby achieving a better auxiliary drying effect and better performance.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-8 The present invention provides the following technical solution:

[0038] Example 1: The solution disclosed in this example is mainly to solve the problems existing in the fabric in the prior art, and the solution is as follows: Figures 1-2As shown, the fabric consists of an inner lining 2 and an outer layer 1. The fabric is composed of two types: an outer layer 1 and an inner lining 2. To ensure a comfortable wearing experience, the inner lining 2 can be made of cotton fiber or a blend of cotton and polyester fiber. The outer layer 1 is mainly made of pure polyester fiber, which has better elasticity and abrasion resistance. Specifically, it can also be made of polyester, nylon, or ice silk, etc. The inner and outer layers are connected by stitching or bonding to form linear or cross-connected areas. These areas are used to accommodate moisture-wicking components, which are in contact with flow-guiding components. The flow-guiding components located between the inner lining 2 and the outer layer 1 are in perpendicular contact with the moisture-wicking components and are staggered. The flow-guiding components are used to absorb moisture and guide it to the moisture-wicking components. The flow-guiding components include evenly distributed flow-guiding lines 3. The upper end face of the flow-guiding line 3 is attached to the inner surface of the outer layer 1, while the lower end face of the flow-guiding line 3 is attached to the upper surface of the moisture-wicking components. Normally, the outer layer of the fabric gets wet, but the improvement of this solution is to use the guide line 3 to absorb the water and let it flow along the guide line 3 under capillary action, and then enter the moisture-wicking component, so that the water can be concentrated and treated, and the inner layer is prevented from being over-wetted.

[0039] The solution discloses one of many forms of moisture-wicking components, such as... Figure 3 The moisture-wicking component shown includes a flexible strip 4 made of non-absorbent material. The upper surface of the flexible strip 4 is a concave arc-shaped guide surface 5, which is used to collect moisture from the guide line 3 and form a guide structure. The guide line 3 above the flexible strip 4 is disconnected. The moisture-wicking component is a flexible strip structure, specifically the flexible strip 4. The flexible structure is designed to prevent the bending performance of the fabric from being affected too much. The guide surface 5 is used to allow the guide line 3 to fit better and to allow the water collected at the disconnection of the guide line 3 to be fully guided and flowed, thereby achieving a multi-dimensional moisture-wicking effect without affecting the breathability of the fabric itself.

[0040] Example 2: The solution disclosed in this example is another form of moisture-wicking component, such as... Figures 4-6As shown, the moisture-wicking component is a water-absorbing line 6, and the lower end face of the water-absorbing line 6 is attached to the upper surface of the water-resistant membrane 7, which is attached to the inner surface of the inner lining 2. The guide line 3 above the water-absorbing line 6 is non-disconnected. The water-absorbing line 6 is used to expand after absorbing water and separate the inner lining 2 and the outer layer 1. The surface of the outer layer 1 has a breathable slit 8 located on the side of the water-absorbing line 6. The outer layer 1 is made of elastic material. The breathable slit 8 is pulled open to form a breathable hole after the water-absorbing line 6 absorbs water and expands. In the embodiment, the strip structure that does not absorb water itself is replaced with the water-absorbing line 6. The fibrous material of the water-absorbing line 6 itself is... The material can better adhere to the fabric, and after absorbing water, it can expand rapidly. On the one hand, it can absorb most of the water in the guide lines 3 and the outer layer 1, achieving a better water absorption effect. On the other hand, it can push and deform the outer layer 1, creating a certain gap between the outer and inner layers, preventing excessive water from seeping into the lining 2, thus achieving a better waterproof effect. Moreover, after the outer layer 1 deforms, the breathable seam 8 will be pulled open accordingly, forming multiple air circulation channels, thereby achieving a better auxiliary drying effect. Under normal conditions, the breathable seam 8 will be in a close-fitting state.

[0041] The fabric preparation method includes the following steps:

[0042] Step 1: Pre-treatment of the inner lining side: The hot press laminating machine applies the waterproof membrane 7 to the inner surface of the inner lining 2 by hot pressing. The precision dispensing machine / hot air bonding machine is used to position the water absorption line 6 according to the design spacing, and the lower end is hot-pressed and bonded to the upper surface of the waterproof membrane 7.

[0043] Step 2: Pre-treatment of the outer layer: Laser cut the pre-set ventilation seam 8 on the surface of the outer layer 1, and evenly lay the guide line 3 on the inner surface of the outer layer 1 in an interlaced grid, and fix it with a small amount of hot melt adhesive.

[0044] Step 3: Outer and inner layer lamination: The pre-treated inner lining 2 and outer layer 1 are precisely aligned and overlapped. Linear / cross connection areas are formed at predetermined positions by sewing or applying adhesive. The connection area extends through the outer and inner layers, fixing the two locally. The non-connection area forms a channel to accommodate the absorbent line 6, ensuring that the absorbent line 6 is in contact with the guide line 3. The composite structure is then subjected to low-temperature hot pressing to strengthen the interlayer adhesion.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
