Description

Technical Field

[0001] The present invention relates to the technical field of composite fabrics, in particular to a multi-dimensional moisture-conducting and breathable composite fabric and a preparation method thereof. Background Art

[0002] Multi-layer fabrics have a wider range of uses and relatively richer functions, such as anti-static or waterproof, etc. After being made into garments, the above fabrics can also achieve a better wearing experience and adapt to some special environmental requirements.

[0003] In the prior art, a moisture-conducting polyester fabric with publication number CN219256717U, relating to the field of textile technology, aims to address the difficulty of cleaning oily stains from woven placemats. The key technical features of the fabric include an outer layer and an inner layer. The outer layer has a plurality of moisture-draining holes (I) arrayed on its surface, and the inner layer has a plurality of moisture-draining holes (II) arrayed on its surface. Several absorbent fabrics are bonded between the outer and inner layers to block the moisture-draining holes (II), forming a moisture-conducting cavity between the inner and outer layers. The moisture-draining holes (I) communicate with the moisture-conducting cavity, and the cavity is integrally formed with moisture-conducting ridges, with the guide surfaces of the ridges facing the absorbent fabrics on either side. This novel moisture-conducting polyester fabric achieves the technical effect of moisture-conducting and oil-removing by using polypropylene and viscose fibers.

[0004] The prior art publication number CN218558220U discloses a moisture-conducting, antibacterial nylon fabric comprising a nylon base fabric and multiple moisture-conducting, antibacterial units disposed on the nylon base fabric. The units comprise inner and outer antibacterial fiber fabrics, respectively disposed on either side of the nylon base fabric. The inner antibacterial fiber fabric is fixedly connected to multiple moisture-conducting cotton threads that pass through the nylon base fabric and the outer antibacterial fiber fabric. The moisture-conducting, antibacterial nylon fabric disclosed in this application, by providing multiple moisture-conducting, antibacterial units on the nylon base fabric, effectively improves the overall moisture-conducting and antibacterial properties of the fabric.

[0005] The above-mentioned existing technologies have made many improved designs on traditional fabrics and also have moisture-conducting effects, but there are still some defects. Because the fibers or lines used for moisture conduction are located between the double-layer / multi-layer structure of the fabric, even if the moisture-conducting effect can be achieved, it only transfers moisture from one area of ​​the fabric to another area, and the moisture between the inner and outer layers is not isolated, resulting in this type of fabric being used as a garment material. When worn in special environments, it feels poor. Summary of the Invention

[0006] The purpose of the present invention is to provide a multi-dimensional moisture-conducting and breathable composite fabric and a preparation method thereof, so as to solve the problem proposed in the above background technology that the fibers or lines used for moisture conduction in the prior art are located between the double-layer / multi-layer structure of the fabric. Even if the moisture conduction effect can be achieved, it only transfers moisture from one area of ​​the fabric to another area, and the moisture between the inner and outer layers is not isolated, resulting in the problem that when this type of fabric is used as a clothing material, it does not feel good when worn in special environments.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a multi-dimensional moisture-conducting and breathable composite fabric and a preparation method thereof, comprising an inner lining and an outer layer, wherein linear or cross-connected areas are formed between the outer and inner layers by stitching lines or bonding, and the areas are used to accommodate moisture-conducting parts, wherein the moisture-conducting parts are also in contact with the flow-conducting parts, and the flow-conducting parts located between the inner lining and the outer layer are in vertical contact with the moisture-conducting parts and are staggered, and the flow-conducting parts are used to absorb moisture and guide it into the moisture-conducting parts.

[0008] As a further feature, the guide member includes evenly distributed guide lines.

[0009] Furthermore, the upper end surface of the guide wire is attached to the inner surface of the outer layer.

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

[0011] As a further feature, the moisture-conducting component comprises a flexible strip of non-water-absorbent material, wherein the upper end surface of the flexible strip is a concave arc-shaped guiding surface.

[0012] Furthermore, the guide surface is used to collect moisture in the guide line and form a guide structure.

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

[0014] Furthermore, the moisture-conducting component is a water absorption line, and the lower end surface of the water absorption line is attached to the upper surface of the water-isolating membrane, and the water-isolating membrane is attached to the inner surface of the lining.

[0015] Furthermore, the guide line above the water absorption line is non-disconnected, and the water absorption line is used to expand after absorbing water and separate the inner lining and the outer layer.

[0016] Furthermore, the surface of the outer layer is provided with a ventilation seam located on the side of the water absorption line.

[0017] Furthermore, the outer layer is made of elastic material, wherein the ventilation seams are pulled open to form ventilation holes after the water absorption line absorbs water and expands.

[0018] The method for preparing the fabric comprises the following steps: Step 1: Pretreatment of the lining side: Use a hot pressing laminating machine to heat-press the water-isolating film onto the inner surface of the lining. Use a precision dispensing machine / hot air bonding machine to position the water absorption line according to the designed spacing, and heat-press and bond the lower end onto the upper surface of the water-isolating film. Step 2: Pre-treatment of the outer layer: Laser cut the preset breathable seams on the outer layer surface, evenly lay the guide lines on the inner surface of the outer layer in a staggered grid, and initially fix them with a small amount of hot melt adhesive; Step 3: Outer and inner layer composite: The pre-treated inner lining is precisely aligned and overlapped with the outer layer. Linear / cross-connected areas are formed at predetermined positions by stitching or gluing. The connection area runs through the outer and inner layers to locally fix the two. The non-connected area forms a channel to accommodate the water absorption line and ensures that the water absorption line is in contact with the guide line. The composite structure is subjected to low-temperature hot pressing to strengthen the interlayer bonding.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the multi-dimensional moisture-conducting and breathable composite fabric and its preparation method redesign the moisture-conducting structure between the inner and outer layers. On the one hand, it can absorb and guide moisture from multiple dimensions, and on the other hand, it can avoid the lining part of the fabric from being excessively affected. At the same time, it can use moisture conduction and water absorption to guide the fabric to undergo simple deformation and achieve the effect of auxiliary rapid drying, which is better, as shown in the following content.

[0020] 1. Densely distributed guide lines are used to contact the outer layer, so that the moisture absorbed by the outer layer is evenly and quickly absorbed. The full contact between the guide lines and the moisture-conducting components realizes the secondary transfer of moisture, thereby preventing the moisture from being reabsorbed by the lining and affecting the drying effect of the inner layer of the fabric. Furthermore, the moisture-conducting component is designed as an elastic flexible strip structure, which can enhance the overall structural strength of the fabric on the one hand, and on the other hand can utilize its arc-shaped guiding surface to effectively collect and drain moisture, thereby achieving a better moisture-conducting effect.

[0021] 2. Using water-absorbing threads instead of moisture-wicking components can not only improve the integrity of the fabric, but also achieve better moisture-wicking performance by utilizing its good water-absorbing effect. At the same time, its characteristic of rapid expansion after absorbing water can be used 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 cooperate with the expanded space and breathable seams to form multiple ventilation channels, thereby achieving better auxiliary drying effect and better use effect.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-8 , the present invention provides the following technical solutions: Example 1: The solution disclosed in this embodiment is mainly to solve the problems existing in the fabric in the prior art, and the solution is as follows Figure 1-Figure 2 As shown, it includes an inner lining 2 and an outer layer 1. The fabric composition is divided into two types: the outer layer 1 and the inner lining 2. While ensuring the wearing experience, the inner lining 2 can be cotton fiber or a blended material of cotton fiber and polyester fiber, while the outer layer 1 is mainly pure polyester fiber, which has better elasticity and wear resistance. Specifically, it can also be polyester, nylon or ice silk, etc. Linear or cross-connected areas are formed between the outer and inner layers by stitching or bonding, and the areas are used to accommodate moisture-conducting parts, wherein the moisture-conducting parts are also in contact with the flow-conducting parts, and the flow-conducting parts located between the inner lining 2 and the outer layer 1 are in vertical contact with the moisture-conducting parts and are staggered. The flow-conducting parts are used to absorb moisture and guide it into the moisture-conducting parts. The flow-conducting parts include evenly distributed flow-conducting lines 3, and the upper end surface of the flow-conducting lines 3 is attached to the inner surface of the outer layer 1, and the local lower end surface of the flow-conducting lines 3 is attached to the upper surface of the moisture-conducting parts. Under normal conditions, the outside of the fabric is usually exposed to water. The improvement direction of this solution is to use the guide line 3 to absorb the moisture and flow along the guide line 3 under capillary action, and then enter the moisture-conducting component, so that the moisture can be concentrated and processed to avoid the inner layer from being overly soaked.

[0026] The scheme discloses one of the many forms of moisture-conducting parts, such as Figure 3 The moisture-conducting component shown includes a flexible strip 4 of non-water-absorbent material, wherein the upper end surface of the flexible strip 4 is an inwardly concave arc-shaped guide surface 5, and the guide surface 5 is used to collect moisture in the guide line 3 and form a guide structure. The guide line 3 above the flexible strip 4 is disconnected, and the moisture-conducting component is a strip structure with a flexible structure, specifically a flexible strip 4. The design of the flexible structure is also to prevent the bending performance of the fabric from being affected too much. The guide surface 5 is on the one hand to ensure that the guide line 3 can fit better, and on the other hand to ensure that the water collected at the disconnection of the guide line 3 is fully guided to flow, thereby achieving a multi-dimensional moisture-conducting effect without affecting the breathability of the fabric itself.

[0027] Embodiment 2: The solution disclosed in this embodiment is another form of the moisture-conducting member, such as Figure 4-Figure 6 As shown, the moisture-conducting component is a water-absorbing line 6, and the lower end surface of the water-absorbing line 6 is attached to the upper surface of the water-isolating membrane 7, and the water-isolating membrane 7 is attached to the inner surface of the lining 2. The guide line 3 above the water-absorbing line 6 is a non-disconnected setting, and the water-absorbing line 6 is used to expand after absorbing water and separate the lining 2 and the outer layer 1. The surface of the outer layer 1 is provided with a breathable seam 8 located on the side of the water-absorbing line 6. The outer layer 1 is an elastic material, wherein the breathable seam 8 is pulled open to form a breathable hole after the water-absorbing line 6 absorbs water and expands. The strip structure of the embodiment that does not absorb water itself is replaced with the water-absorbing line 6, and the fiber material of the water-absorbing line 6 itself is The material can fit better in the fabric, and can expand rapidly after absorbing water. On the one hand, it can absorb most of the moisture in the guide line 3 and the outer layer 1 to achieve a better water absorption effect. On the other hand, it can make the outer layer 1 be pushed and deformed, so that a certain distance is separated between the outer and inner layers to avoid excessive moisture from seeping into the lining 2, thereby achieving a better waterproof effect. Moreover, after the outer layer 1 is deformed, the breathable seam 8 will be pulled open accordingly to form multiple air circulation channels, thereby achieving a better auxiliary drying effect. Under normal conditions, the breathable seam 8 will be in a fitted state.

[0028] The method for preparing the fabric comprises the following steps: Step 1: Pretreatment of the lining side: Use a hot pressing laminating machine to heat-press the water-isolating film 7 onto the inner surface of the lining 2. Use a precision glue dispenser / hot air bonding machine to position the water-absorbing wires 6 according to the designed spacing, and heat-press and bond the lower end to the upper surface of the water-isolating film 7. Step 2: Pre-treatment of the outer layer: Laser cut the pre-set breathable seams 8 on the surface of the outer layer 1, evenly lay the guide wires 3 on the inner surface of the outer layer 1 in a staggered grid, and initially fix them with a small amount of hot melt adhesive; Step 3: Composite the outer and inner layers: Accurately align the pre-treated inner lining 2 and the outer layer 1, and form linear / cross-connected areas at predetermined positions by stitching or gluing. The connection area runs through the outer and inner layers to locally fix the two. The non-connected area forms a channel to accommodate the water absorption line 6, and ensures that the water absorption line 6 is in contact with the guide line 3. The composite structure is subjected to low-temperature hot pressing to strengthen the interlayer bonding.
