Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and in particular to a moisture-wicking and breathable hemp composite fabric. Background Technology

[0002] Pure linen fabric is a fabric made from natural linen fibers (such as flax, hemp, etc.). Linen fiber is a plant fiber with good breathability, moisture absorption, and antibacterial properties. Due to its excellent breathability, moisture absorption, and antibacterial properties, it is widely used in the clothing industry.

[0003] While traditional pure linen fabrics offer superior moisture absorption, their slow wicking speed leads to sweat buildup around the skin, causing a damp, sticky, and stuffy feeling, especially during exercise or in high-temperature environments. Fabrics made solely from moisture-wicking synthetic fibers (such as Coolmax polyester) wick away sweat quickly, but their initial moisture absorption capacity is inferior to natural fibers (especially linen), and their feel, breathability, and natural skin-friendly texture are not as good. Therefore, how to organically combine the excellent moisture absorption, breathability, antibacterial properties, and natural texture of linen with the efficient moisture-wicking capabilities of synthetic fibers to create a functional fabric that combines the advantages of both is a pressing technical problem in this field. To address this, we propose a moisture-wicking linen composite fabric. Utility Model Content

[0004] The purpose of this invention is to provide a moisture-wicking and breathable hemp composite fabric to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a moisture-wicking and perspiration-absorbing hemp composite fabric, comprising a fast-diffusion evaporation layer, a one-way moisture-wicking layer, and a skin-friendly moisture-wicking layer that are sequentially stacked and connected in a direction from the outside to the inside;

[0006] The rapid diffusion evaporation layer is woven from blended or interwoven yarns containing hemp fibers and hydrophobic synthetic fibers.

[0007] The one-way moisture-wicking layer is woven or nonwoven from hydrophobic synthetic long fibers. The one-way moisture-wicking layer has a fibrous mesh structure with a dense inner layer and a sparse outer layer along the direction of the skin-friendly moisture-absorbing layer and the rapid diffusion evaporation layer.

[0008] The skin-friendly, moisture-absorbing layer is woven from hemp fiber yarn.

[0009] Preferably, the hemp fiber yarn used in the skin-friendly moisture-absorbing layer is one or more blended yarns selected from flax yarn, ramie yarn, jute yarn, or hemp yarn.

[0010] Preferably, the hydrophobic synthetic fiber filament used in the one-way moisture-wicking layer is any one of polyester filament, polypropylene filament, or nylon filament.

[0011] Preferably, hot melt adhesive is provided between the rapid diffusion evaporation layer and the one-way moisture-wicking layer, as well as between the one-way moisture-wicking layer and the skin-friendly moisture-absorbing layer, so that the rapid diffusion evaporation layer, the one-way moisture-wicking layer and the skin-friendly moisture-absorbing layer are bonded together by hot melt adhesive.

[0012] Preferably, the hot melt adhesive located between the rapid diffusion evaporation layer and the one-way moisture-wicking layer, and between the one-way moisture-wicking layer and the skin-friendly moisture-absorbing layer, is distributed in a dot matrix pattern, and the density of the hot melt adhesive dots is 80-120 dots / cm². 2 .

[0013] Preferably, the thickness of the skin-friendly moisture-absorbing layer is 0.1–0.3 mm, the thickness of the one-way moisture-wicking layer is 0.05–0.15 mm, and the thickness of the rapid diffusion evaporation layer is 0.2–0.6 mm, wherein the thickness of the rapid diffusion evaporation layer is greater than the thickness of the skin-friendly moisture-absorbing layer, and the thickness of the skin-friendly moisture-absorbing layer is greater than the thickness of the one-way moisture-wicking layer.

[0014] Compared with the prior art, the technical effects of this utility model are as follows:

[0015] The composite fabric provided by this utility model has excellent hydrophilicity and capillary effect due to the use of hemp fiber in the skin-friendly moisture-absorbing layer, which effectively absorbs sweat from the skin surface. Then, through the hydrophobic synthetic fiber structure with dense inner layer and loose outer layer in the unidirectional moisture-wicking layer, liquid water in the skin-friendly moisture-absorbing layer can enter the rapid diffusion evaporation layer unidirectionally through capillary pressure difference. Combined with the moisture absorption of hemp fiber and the moisture-wicking properties of synthetic fiber in the rapid diffusion evaporation layer, the liquid water transferred from the unidirectional moisture-wicking layer can be dispersed, increasing the evaporation area of ​​liquid water, thereby achieving excellent moisture absorption and perspiration wicking effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1The illustrated moisture-wicking hemp composite fabric includes a rapidly diffusing evaporation layer 101, a one-way moisture-wicking layer 102, and a skin-friendly moisture-wicking layer 103, which are sequentially layered and connected from the outside to the inside. The rapidly diffusing evaporation layer 101 is woven from blended or interwoven yarns containing hemp fibers and hydrophobic synthetic fibers. The one-way moisture-wicking layer 102 is woven or nonwoven from hydrophobic synthetic filaments. The one-way moisture-wicking layer 102 has a dense inner and loose outer fiber mesh structure along the direction of the skin-friendly moisture-wicking layer 103 and the rapidly diffusing evaporation layer 101. Specifically, special processes such as bicomponent spunbonding and gradient carding can be used to make the one-way moisture-wicking layer 102 into a fiber mesh. This design allows the fibers of the unidirectional moisture-wicking layer 102 closer to the skin-friendly moisture-wicking layer 103 to be finer and more densely packed, while the fibers closer to the rapid diffusion evaporation layer 101 are relatively coarser and looser in density. This creates strong capillary action in the denser area, drawing liquid water out of the skin-friendly moisture-wicking layer 103 and guiding it naturally into the rapid diffusion evaporation layer 101 through the capillary gradient and the channels formed by the hydrophobic fibers. The skin-friendly moisture-wicking layer 103 is woven from hemp fiber yarn and, as the inner layer, directly contacts the skin, retaining the excellent moisture-wicking, breathable, antibacterial, and antistatic properties of hemp fibers. The rapid diffusion evaporation layer 101... The outer layer of the composite fabric also incorporates hemp fibers, partially retaining the appearance, feel, and some functionality of hemp. Meanwhile, the composite structure formed by the rapid diffusion evaporation layer 101, the one-way moisture-wicking layer 102, and the skin-friendly moisture-wicking layer 103 enhances the fabric's durability and dimensional stability. When the hemp composite fabric is used as clothing material, the skin-friendly moisture-wicking layer 103 utilizes the excellent hydrophilicity and capillary effect of hemp fibers to quickly absorb sweat from the skin's surface. The one-way moisture-wicking layer 102, located in the middle, utilizes a hydrophobic synthetic fiber structure to unidirectionally guide the liquid water absorbed by the skin-friendly moisture-wicking layer 103 into the rapid diffusion evaporation layer 101 through capillary pressure difference. Then, in conjunction with the hygroscopic properties of hemp fibers and the moisture-wicking properties of synthetic fibers in the rapid diffusion evaporation layer 101, the moisture conducted by the one-way moisture-wicking layer 102 is rapidly diffused and spread over a large area on its outer surface, increasing the evaporation area. This allows for accelerated evaporation by utilizing external airflow and body temperature. In this way, the synergistic action of the skin-friendly moisture-absorbing layer 103, the one-way moisture-wicking layer 102, and the rapid diffusion evaporation layer 101 in the sequence of moisture absorption, conduction, and diffusion evaporation significantly reduces the accumulation of sweat on the skin surface, keeps the skin contact surface relatively dry, effectively eliminates the stickiness and stuffiness of traditional hemp fabrics after sweating, and improves the comfort of wearing clothing made of hemp composite fabrics.

[0020] It should be noted that the thickness of the skin-friendly moisture-absorbing layer 103 is 0.1–0.3 mm, the thickness of the one-way moisture-wicking layer 102 is 0.05–0.15 mm, and the thickness of the rapid diffusion evaporation layer 101 is 0.2–0.6 mm. The thickness of the rapid diffusion evaporation layer 101 is greater than that of the skin-friendly moisture-absorbing layer 103, and the thickness of the skin-friendly moisture-absorbing layer 103 is greater than that of the one-way moisture-wicking layer 102. The thickness design of the rapid diffusion evaporation layer 101, the one-way moisture-wicking layer 102, and the skin-friendly moisture-absorbing layer 103 can maximize the moisture conductivity by making the one-way moisture-wicking layer 102 thinner, while thickening the rapid diffusion evaporation layer 101 can improve the evaporation capacity. The moderate thickness of the skin-friendly moisture-wicking layer 103 ensures moisture absorption comfort. The thinnest one-way moisture-wicking layer 102, together with its moderate capillary force, achieves the function of directional conduction of liquid water.

[0021] In a preferred embodiment, the hemp fiber yarn used in the skin-friendly moisture-wicking layer 103 is one or more blended yarns of flax yarn, ramie yarn, jute yarn, or hemp yarn. The use of multiple hemp fibers or combinations can adapt to use in various environments, making the application range of hemp composite fabrics wider. The hydrophobic synthetic fiber filament used in the one-way moisture-wicking layer 102 is any one of polyester filament, polypropylene filament, or nylon filament. By using multiple hydrophobic synthetic fibers as the optional materials for manufacturing the one-way moisture-wicking layer 102, adaptive selection can be made according to the application environment of the hemp composite fabric to maximize the excellent performance of the hemp composite fabric.

[0022] Furthermore, hot melt adhesive is provided between the rapid diffusion evaporation layer 101 and the one-way moisture-wicking layer 102, as well as between the one-way moisture-wicking layer 102 and the skin-friendly moisture-absorbing layer 103, so that the rapid diffusion evaporation layer 101, the one-way moisture-wicking layer 102, and the skin-friendly moisture-absorbing layer 103 are bonded together by hot melt adhesive. The hot melt adhesive between the rapid diffusion evaporation layer 101 and the one-way moisture-wicking layer 102, and between the one-way moisture-wicking layer 102 and the skin-friendly moisture-absorbing layer 103, is distributed in a dot matrix pattern, and the density of the hot melt adhesive dots is 80–120 dots / cm². 2 The rapid diffusion evaporation layer 101, the one-way moisture-wicking layer 102, and the skin-friendly moisture-absorbing layer 103 are bonded together by hot melt adhesive. With the hot melt adhesive dot matrix design, it can ensure that the layers are firmly bonded together, while ensuring that the moisture-wicking channels formed on the one-way moisture-wicking layer 102 are not affected, thus maintaining the smooth flow of water and the softness of the fabric.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
