Description

Technical Field

[0001] This utility model relates to the textile field, specifically to a moisture-absorbing and waterproof yarn. Background Technology

[0002] Conventional yarns typically only have basic warmth or decorative functions. In certain specific usage scenarios, such as outdoor sports, clothing needs to have both moisture-wicking and waterproof functions to keep the wearer comfortable and dry. In the field of medical protection, protective equipment needs to be able to absorb human secretions while preventing the penetration of external liquids to ensure protective effectiveness. In such cases, yarns need to have both moisture-wicking and waterproof functions.

[0003] Moisture-wicking yarns typically absorb sweat from clothing by adding moisture-wicking fibers, while waterproof yarns prevent water from penetrating the garment through special waterproofing treatments or the use of waterproof fibers. To meet the dual needs of moisture absorption and waterproofing, current clothing often employs a double-layer fabric approach: moisture-wicking yarns form the inner layer, and waterproof yarns form the outer layer. This increases the fabric thickness, which can affect breathability to some extent. Furthermore, the increased use of functional yarns also impacts production costs. Utility Model Content

[0004] The purpose of this invention is to provide a moisture-absorbing and waterproof yarn that can prevent rainwater from penetrating into the external environment while also absorbing sweat from the human body, thus improving the functionality of the yarn.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A moisture-absorbing and waterproof yarn, comprising:

[0007] First fiber yarn;

[0008] A plurality of second fiber yarns are arranged parallel to the first fiber yarns. Each second fiber yarn is arranged at an equal angle around the central axis of the first fiber yarn. A first moisture-absorbing fiber yarn is provided between adjacent second fiber yarns and the first moisture-absorbing fiber yarn is sandwiched between two second fiber yarns. Each second fiber yarn and the first moisture-absorbing fiber yarn form a moisture-absorbing layer.

[0009] Several waterproof fiber yarns are wound around the moisture-absorbing layer at equal intervals. A second moisture-absorbing fiber yarn is provided between adjacent waterproof fiber yarns and sandwiched between the two waterproof fiber yarns. The waterproof fiber yarns and the second moisture-absorbing fiber yarns are combined to form a waterproof layer. The moisture-absorbing layer is sandwiched between the first fiber yarn and the waterproof layer.

[0010] As a further improvement to the above technical solution, the diameter of the waterproof fiber yarn is twice the diameter of the second moisture-absorbing fiber yarn, and the adjacent waterproof fiber yarns and the second moisture-absorbing fiber yarn between them form a water-guiding groove.

[0011] As a further improvement to the above technical solution, the diameter of the second fiber yarn is the same as the diameter of the first moisture-absorbing fiber yarn.

[0012] As a further improvement to the above technical solution, the first and second moisture-absorbing fiber yarns are provided with a number of grooves at equal intervals along their circumference on their sides.

[0013] As a further improvement to the above technical solution, the first fiber yarn, the waterproof fiber yarn, and the second moisture-absorbing fiber yarn are all single yarn structures, and the second fiber yarn and the first moisture-absorbing fiber yarn are both ply yarn structures.

[0014] Compared with the prior art, this utility model has the following advantages and effects:

[0015] This invention utilizes a structure consisting of a first fiber yarn and a moisture-absorbing layer formed thereon by a second fiber yarn and a first moisture-absorbing fiber yarn. Combined with the waterproof effect of the waterproof layer formed by the waterproof fiber yarn and the second moisture-absorbing fiber yarn, as well as the fixing effect on the moisture-absorbing layer, the yarn can both prevent rainwater from penetrating the external environment and absorb sweat from the body. This improves the functionality of the yarn. Compared to double-layer fabrics, it reduces the thickness of the fabric woven from the yarn while still meeting functional requirements, thus lowering the production cost of clothing and reducing its impact on breathability.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] See Figures 1-3 This embodiment discloses a moisture-absorbing and waterproof yarn, comprising a first fiber yarn 1, a plurality of second fiber yarns 2, and a plurality of waterproof fiber yarns 3. The first fiber yarn 1 and the second fiber yarns 2 are arranged parallel to each other. Each second fiber yarn 2 is arranged at an equal angle around the central axis of the first fiber yarn 1. A first moisture-absorbing fiber yarn 4 is provided between adjacent second fiber yarns 2, and the first moisture-absorbing fiber yarn 4 is sandwiched between two second fiber yarns 2. Each second fiber yarn 2 and the first moisture-absorbing fiber yarn 4 form a moisture-absorbing layer 5. Each waterproof fiber yarn 3 is wound around the moisture-absorbing layer 5 at equal intervals. Adjacent waterproof fiber yarns... A second moisture-absorbing fiber yarn 6 is provided between the fiber yarns 3 and sandwiched between two waterproof fiber yarns 3. The waterproof fiber yarns 3 and the second moisture-absorbing fiber yarn 6 surround each other to form a waterproof layer 7. The moisture-absorbing layer 5 is sandwiched between the first fiber yarn 1 and the waterproof layer 7. The hydrophobicity of the waterproof fiber yarn 3 and the moisture absorption of the first moisture-absorbing fiber yarn 4 and the second moisture-absorbing fiber yarn 6 enable the fabric formed by the yarn to not only block water (such as rainwater) from the external environment from penetrating inward, but also absorb human sweat, thereby keeping the inside of the clothing dry.

[0022] In this embodiment, the first fiber yarn 1, the waterproof fiber yarn 3, and the second moisture-absorbing fiber yarn 6 are all single yarn structures, while the second fiber yarn 2 and the first moisture-absorbing fiber yarn 4 are both ply structures. While it is possible to increase the strength by combining and twisting multiple identical single yarns, it is also possible to improve the performance by combining and twisting different single yarns. For example, combining and twisting bamboo fiber single yarn and cotton fiber single yarn to form the first moisture-absorbing fiber yarn 4 can not only improve the moisture absorption effect, but also have antibacterial and bacteriostatic functions, reducing the risk of bacterial growth after the yarn absorbs moisture.

[0023] See Figure 1 The diameter of the second fiber yarn 2 is the same as that of the first moisture-absorbing fiber yarn 4, which ensures the winding strength of the waterproof fiber yarn 3 and the second moisture-absorbing fiber yarn 6, reduces the risk of changes in the relative positions between the fibers, and thus ensures the stability of the yarn structure.

[0024] See Figure 2 The diameter of the waterproof fiber yarn 3 is twice the diameter of the second moisture-absorbing fiber yarn 6. The adjacent waterproof fiber yarns 3 and the second moisture-absorbing fiber yarn 6 between them form a water-guiding groove 8, which can collect and absorb water. The guiding effect of the water-guiding groove 8 can also increase the absorption area and ensure the moisture absorption efficiency and effect.

[0025] See Figure 3 The first moisture-absorbing fiber yarn 4 and the second moisture-absorbing fiber yarn 6 are provided with a number of grooves 9 at equal intervals along their circumference on their sides, which increases the surface area and improves the moisture absorption effect.

[0026] In this embodiment, the grooves 9 on the first moisture-absorbing fiber yarn 4 and the second moisture-absorbing fiber yarn 6 can be formed by changing the shape of the spinneret orifice during their extrusion molding.

[0027] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
