Description

Technical Field

[0001] This application belongs to the textile field, and in particular relates to a waterproof composite fabric and clothing. Background Technology

[0002] Current technologies typically employ a process of pre-applying adhesive layers to both sides of the intermediate windproof layer, followed by laminating a breathable mesh layer and a waterproof layer. This method suffers from several drawbacks: difficulty in controlling the alignment accuracy between layers, the potential introduction of air bubbles or weak adhesion zones, affecting the uniformity and strength of the bond; furthermore, the fabric edges rely entirely on adhesive bonding, making them highly susceptible to delamination and peeling under subsequent sewing, wear, and environmental stress. This creates weak points for waterproofing failure and structural damage, and subsequent sewing processes further weaken the edge bonding structure, compromising the overall waterproof performance and structural integrity of the fabric. Utility Model Content

[0008] Furthermore, the windproof layer and the waterproof layer each have several layers, and the windproof layers and the waterproof layers are alternately distributed on one surface of the breathable mesh layer.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical 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 based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0025] Example 1

[0026] like Figure 1 and Figure 4 As shown, the waterproof composite fabric includes a windproof layer 1 in the middle of the composite fabric, a waterproof layer 3 with waterproof function on both sides of the windproof layer 1, and a breathable mesh layer 2 with breathable function. According to the clothing requirements, the breathable mesh layer 2, the windproof layer 1, and the waterproof layer 3 are distributed sequentially from the inside to the outside, and a composite adhesive layer 4 is provided between each layer. As a multiple option, the windproof layer 1 and the waterproof layer 3 can be provided in several layers and are distributed alternately. This embodiment only describes the application scheme of a single windproof layer 1 and a single waterproof layer 3.

[0027] Specifically, the composite adhesive layer 4 is uniformly coated on the side of the windproof layer 1 facing the waterproof layer 3, and the composite adhesive layer 4 is also uniformly coated on the side of the breathable mesh layer 2 facing the windproof layer 1. Its special features include... Figure 2 and Figure 3 As shown, the composite adhesive layer 4 on the windproof layer 1 is distributed in a dotted pattern on the surface of the windproof layer 1 facing the waterproof layer 3; as Figure 2 and Figure 4 As shown, the composite adhesive layer 4 disposed on the breathable mesh layer 2 is distributed in strips on one surface of the breathable mesh layer 2 facing the windproof layer 1.

[0028] In practice, the composite adhesive layer 4, dotted on the surface of the windproof layer 1, is applied using a dotting process. This design ensures effective adhesion between the waterproof layer 3 and the windproof layer 1 while maximizing the preservation of breathable pores between the windproof layer fibers, avoiding the loss of breathability caused by full-coat adhesive. Meanwhile, the strip-shaped composite adhesive layer 4 on the surface of the breathable mesh layer 2 is applied directionally along the mesh lines. Through a layered differentiated adhesive application process: the dotted adhesive on the windproof layer side achieves a balance between breathability and adhesion, while the strip-shaped adhesive on the breathable mesh layer side enhances the reliability of the structure and edges.

[0029] Furthermore, a stitching thread 5 is provided along the edge of the breathable mesh layer 2. This stitching thread 5 is not simply sewn onto the surface, but is deeply embedded in the circumferential edge structure of the breathable mesh layer 2 through a special weaving process. This integrated weaving and embedding design allows the yarn of the stitching thread 5 to intertwine and entwine with the edge fibers of the breathable mesh layer 2, forming a physical interlock. Its effect far surpasses that of traditional sewing. The resulting strong edge structure can withstand the high-intensity punctures and pulls of subsequent garment sewing processes, ensuring that the integrity of the composite structure at the garment seams is not damaged, and greatly improving the tensile strength of the fabric.

[0030] The thickness of the breathable mesh layer 2 is greater than that of the windproof layer 1, and the thickness of the windproof layer 1 is greater than that of the waterproof layer 3. The thicker breathable mesh layer 2 is closer to the human body, and its ample three-dimensional spatial structure provides excellent softness, moisture absorption and wicking capacity, and physical cushioning, effectively avoiding the friction discomfort or "sticky feeling" that thin mesh fabric may cause, especially improving wearing comfort during high-intensity activities. As the core functional layer, the thickness of the windproof layer 1 needs to be sufficient to provide effective wind resistance while avoiding unnecessary weight gain. Its thickness is between that of the breathable mesh layer 2 and the waterproof layer 3, reflecting the pursuit of lightweight while ensuring windproof performance. The thinnest design of the waterproof layer 3 gives it excellent flexibility and low bending stiffness, allowing the waterproof layer to better cooperate with the deformation of other layers when the fabric is repeatedly bent and stretched, significantly reducing the risk of micro-cracks or interface delamination caused by repeated stress, and improving durability in dynamic environments.

[0031] Specifically, in this embodiment, the breathable mesh layer 2 is a polyester mesh fabric layer; the windproof layer 1 is any one or more combinations of organic cotton layer and recycled nylon layer; and the waterproof layer 3 is a PU environmentally friendly film layer.

[0032] Example 2

[0033] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference is that, for the waterproof composite fabric of Embodiment 1, the garment in this embodiment includes a waterproof composite fabric.

[0034] Clothing is a general term for items worn by humans. The torso, shoulders, and other areas of clothing that are exposed to wind and rain use a complete three-layer structure of waterproof composite fabric to ensure that the core protective area can withstand extreme environments.

[0035] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
