Abstract

This invention discloses a heat-setting plate, a one-way moisture-wicking fabric, and clothing. The heat-setting plate includes a male heat-setting plate and a female heat-setting plate. One side of the male heat-setting plate has several conical needles, and one side of the female plate has a conical recess matching the conical needles, which can be heated. The prepared one-way moisture-wicking fabric has a single or multiple composite one-way moisture-wicking fiber layer. At least one one-way moisture-wicking fiber layer achieves one-way moisture wicking through Laplace pressure, enabling the moisture-absorbing fiber layer to generate a fixed-direction (outward) Laplace pressure on the water vapor inside the clothing. By adjusting the angle of the micro-cone protrusions, it can overlap with the direction of droplet gravity, increasing the driving force for water vapor expulsion while maintaining a clear outward direction, thus improving the water vapor expulsion rate. When the wearer sweats heavily, it can quickly expel water vapor and resist the transport of external water vapor to the inside of the clothing (caused by the capillary action of hydrophilic fibers). It can also keep the inside of the clothing dry in rainy or foggy weather, achieving true one-way moisture wicking.

Description

Technical Field

[0001] The invention relates to a heat setting plate, a one-way moisture conducting fabric and clothing, and belongs to the technical field of clothing production. Background Art

[0002] The comfort of wearing clothing depends largely on the moisture absorption and moisture removal performance of the fabric. Consumer clothing has excellent moisture absorption performance, so that the body can keep dry and comfortable. Therefore, more and more consumers tend to choose pure cotton fabrics. The moisture absorption principle of cotton is to utilize the hydrophilicity and capillary action of cotton fibers. Under normal circumstances, it is competent for keeping the body dry. However, it should be pointed out that the moisture absorption effect of cotton fibers is bidirectional, and it will also lock moisture and retain water to a certain extent. Therefore, when the wearer sweats a lot (the water vapor generated exceeds the moisture absorption and water retention capacity of cotton fibers), or the air humidity is high (the fabric absorbs moisture from the air, that is, reverse moisture absorption), pure cotton fabrics will appear wet and sticky.

[0003] In order to solve the above problems, some attempts to prepare unidirectional moisture-conducting fabrics have appeared in the prior art. However, the technical route widely adopted by the current unidirectional moisture-conducting scheme is to stack multiple layers of fabrics with different moisture absorption capacities to form a composite moisture-conducting fabric, wherein the closer the fabric layer is to the outside, the stronger its moisture absorption capacity. Such a scheme can improve the water retention capacity of the fabric to a certain extent and reduce the humidity on the side where the fabric is directly in contact with the skin. However, it is obvious that such a scheme has not surpassed the principle of traditional moisture-absorbing fabrics. In the case of heavy sweating, the fabric will still be wet and sticky; and, since the moisture absorption capacity of the outer side of the fabric is the strongest, it will absorb a lot of moisture from the air, which will be more obvious in rainy and foggy weather with high air humidity, that is, such a scheme will lead to more serious reverse moisture absorption. Therefore, it is necessary to develop a truly unidirectional moisture-conducting fabric that can maintain good moisture absorption and discharge effects when wearing it in the case of heavy sweating, and can resist reverse moisture absorption in rainy and foggy weather. Summary of the invention

[0004] Purpose of the invention: The first purpose of the present invention is to provide a heat setting plate, the second purpose of the present invention is to provide a one-way moisture-conducting fabric prepared using the heat setting plate, and the third purpose of the present invention is to provide a garment made of the one-way moisture-conducting fabric.

[0005] Technical solution: A heat setting plate of the present invention has a plurality of heated cone needles disposed on one side of the heat setting plate.

[0006] Furthermore, the heat setting plate comprises a heat setting male plate and a heat setting female plate, one side of the heat setting male plate is provided with a plurality of heated cone needles, and one side of the heat setting female plate is provided with a cone-shaped depression matching the cone needles.

[0007] Furthermore, the conical recess may be heated.

[0008] Furthermore, the apex angle of the cone needle is 5-15°.

[0009] Furthermore, the length of the tapered needle is 2-10 mm.

[0010] Furthermore, the cone needles are arranged in an array.

[0011] Furthermore, the cone tip of the cone needle is flat or round.

[0012] Furthermore, the cone needle is arranged obliquely to the heat setting plate. In order to improve wearing comfort and avoid the pricking sensation caused by the micro-cone protrusion, the micro-cone protrusion can be arranged obliquely to the fabric.

[0013] A method for preparing a unidirectional moisture-conducting fabric using the heat setting plate of the present invention comprises the following steps:

[0014] The fiber layer is placed on one side of the cone needle of the heat setting plate, and the cone needle is heated to form a unidirectional moisture-conducting fabric with micro-cone protrusions on the fiber layer;

[0015] Alternatively, the fiber layer is placed between a heat-setting male plate and a heat-setting female plate, and the conical needles of the heat-setting male plate are nested with the conical depressions of the heat-setting female plate to form micro-conical protrusions in the fiber layer. The fiber layer is shaped into a unidirectional moisture-conducting fabric by heating the conical needles and / or the conical depressions. The fiber layer is heated and shaped on both sides for better results.

[0016] The present invention also includes a one-way moisture-conducting fabric, which is made by the preparation method of the present invention.

[0017] Furthermore, the one-way moisture-conducting fabric has a single-layer or multi-layer composite one-way moisture-conducting fiber layer, wherein at least one layer of the one-way moisture-conducting fiber layer achieves one-way moisture-conducting through Laplace pressure.

[0018] Furthermore, one side of the single-layer or multi-layer composite unidirectional moisture-conducting fiber layer is provided with one or more flat fiber layers alone, or both sides of the single-layer or multi-layer composite unidirectional moisture-conducting fiber layer are provided with one or more flat fiber layers simultaneously.

[0019] The present invention uses a heat setting plate with arrayed round-headed cone needles or flat-headed cone needles to replace the flat heat setting plate or hot air heat setting process in the prior art. The arrayed cone needle heat setting plate of the present invention is used to extrude hydrophilic fabrics to form a micro-cone protrusion structure on one side of the fabric that is pushed out by the cone needles. The arrayed cone needle heat setting plate is then heated to shape the micro-cone protrusion structure. The fabric is then separated from the heat setting plate to obtain a fabric with a hydrophilic micro-cone protrusion structure on one side.

[0020] The one-way moisture-conducting fabric in the present embodiment may be composed of a plurality of fiber layers having array-shaped micro-cone protrusions, and the cone tips of the micro-cone protrusions of the fiber layers are arranged toward the inner side of the fabric.

[0021] In order to prevent dust from entering and accumulating in the inner cavity of the micro-cone protrusions (cone-shaped holes opening to the outside of the fabric), it is preferred to stack a flat fiber layer on the outside of the outermost micro-cone protrusion fiber layer, and the flat fiber layer is used to shield the aforementioned inner cavity to prevent dust and other larger impurities from entering and accumulating in the inner cavity. The flat fiber layer is preferably hydrophilic to facilitate the absorption of water at the bottom of the micro-cone array fiber layer inside it. The absorbed water migrates to the outside of the flat fiber layer due to the hydrophilic nature of the fiber, and evaporates and dissipates into the air.

[0022] In order to protect the micro-cone protrusion structure and improve wearing comfort, a second flat fiber layer can also be set on the innermost side of the one-way moisture-conducting fabric. Similarly, the second flat fiber layer should also be hydrophilic, so that the water vapor in the clothing can quickly dissipate outward and come into contact with the micro-cone array.

[0023] The present invention also includes a garment made by using the one-way moisture-conducting fabric of the present invention, wherein the micro-cone protrusions of the one-way moisture-conducting fabric face the inner side of the garment.

[0024] Further, when the micro-cone protrusions of the unidirectional moisture-conducting fabric are arranged obliquely, the cone tips of the micro-cone protrusions are arranged upward relative to the clothing.

[0025] The unidirectional moisture-conducting fabric of the present invention has a single-layer or multi-layer composite moisture-absorbing fiber layer, wherein at least one layer of moisture-absorbing fiber realizes unidirectional moisture-conducting through Laplace pressure. The principle explanation of Laplace pressure refers to China CN102121161A. The unidirectional moisture-conducting fabric of the present invention is realized by an array-like micro-cone protrusion structure formed on the moisture-absorbing fiber, and the cone tip of the micro-cone protrusion structure faces the inner side of the fabric (the side close to the skin). Therefore, after the water vapor in the fabric contacts the micro-cone protrusion structure, the water is subjected to the Laplace pressure on the cone surface of the micro-cone protrusion structure and is transported from the cone tip to the cone bottom, thereby completing the unidirectional moisture-conducting of the water vapor in the clothing; at the same time, when the cone bottom of the micro-cone protrusion structure (which can be understood as the outer side of the clothing) contacts the moisture in the air, the cone surface of the micro-cone protrusion structure also generates Laplace pressure on the water. At this time, the pressure organizes the water to move from the cone bottom to the cone tip, thereby realizing the resistance to the migration of external water vapor to the inside.

[0026] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages:

[0027] (1) The present invention ingeniously designs the structure of the hygroscopic fiber layer so that the hygroscopic fiber layer can generate a fixed-direction (outward) Laplace pressure on the water vapor inside the clothing;

[0028] (2) By adjusting the angle of the micro-cone protrusion, the Laplace pressure can also overlap with the direction of the droplet gravity, thereby further increasing the driving force for water vapor evacuation; the evacuation driving force has a clear outward direction, so it can increase the rate of water vapor evacuation; when the wearer sweats a lot, the water vapor can be quickly discharged; at the same time, the evacuation driving force can also resist the transmission of external water vapor to the inside of the clothing (caused by the capillary action of the hydrophilic fiber), so the inside of the clothing can be kept dry even in rainy and foggy weather. The present invention realizes true one-way moisture conduction. BRIEF DESCRIPTION OF THE DRAWINGS
