Description

Technical Field

[0001] This utility model relates to the field of fabrics, and in particular to a skin-friendly fabric that can release negative ions. Background Technology

[0002] As people's living standards improve, the demand for textiles is no longer limited to warmth and aesthetics, but also places greater emphasis on their health benefits and wearing comfort. Negative ions, known as "air vitamins," have been shown in studies to have positive effects such as purifying the air, eliminating odors, antibacterial properties, promoting metabolism, and relieving fatigue. Therefore, applying negative ion technology to the textile industry and developing fabrics with negative ion release capabilities has become a research hotspot.

[0003] Currently, the main methods for preparing negative ion fabrics are to add negative ion powder (such as tourmaline, kiwistone, opal, etc.) to chemical fibers during the spinning stage to make negative ion masterbatch before spinning; or to coat the fabric surface with negative ion finishing agent through a finishing process.

[0004] A Chinese patent discloses a fabric that can release negative oxygen ions, application number 202022193592.7. The patent mainly attaches a negative ion coating to both sides of the polyurethane layer and directly combines it with the fabric layer, making the release of negative ions smoother.

[0005] However, the negative ion coating forms a thin film structure on the fiber surface and in the fabric gaps. This film may hinder the free flow of air in the fabric. Clothing made with this fabric is prone to causing stuffiness and stickiness when worn, especially in high temperature or sports environments, which greatly reduces comfort. Utility Model Content

[0006] This invention provides a skin-friendly fabric that can release negative ions, which can solve the problem that the negative ion coating in existing skin-friendly fabrics that can release negative ions may hinder the free flow of air in the fabric and reduce wearing comfort.

[0007] A skin-friendly fabric that can release negative ions includes a fabric base layer, a negative ion inner functional layer and a negative ion outer functional layer respectively provided on both sides of the fabric base layer, a support layer provided between the negative ion inner functional layer and the negative ion outer functional layer and the fabric base layer, and a skin-friendly layer provided on one side of the negative ion inner functional layer. The surface of the support layer is designed as a non-flat structure. Both the inner and outer negative ion functional layers are porous mesh structures with attached negative ion materials. The mesh of the inner and outer negative ion functional layers are offset from each other on the projection perpendicular to the plane of the fabric base layer.

[0008] Preferably, the negative ion inner functional layer includes multiple first warp layers and multiple first weft layers, the first warp layers and the first weft layers interweave to form a first shielding part and a first vent, and the surfaces of the multiple first warp layers and the multiple first weft layers are all provided with a first negative ion coating.

[0009] Preferably, the negative ion outer functional layer includes multiple second warp layers and multiple second weft layers, the second warp layers and the second weft layers interweave to form a second shielding portion and a second vent, and the surfaces of the multiple second warp layers and the multiple second weft layers are all provided with a second negative ion coating.

[0010] Preferably, the support layer includes a fabric layer and a protrusion / recess on the surface of the fabric layer.

[0011] Preferably, the first negative ion coating is made of tourmaline or kiwistone.

[0012] Preferably, the second negative ion coating is a photocatalytic material.

[0013] Preferably, the base layer of the fabric is a woven or knitted fabric.

[0014] Preferably, the support layer is a ribbed fabric.

[0015] Preferably, the second warp layer and the second weft layer are made of polyester or nylon.

[0016] Preferably, the skin-friendly layer is a woven or knitted fabric.

[0017] This invention provides a skin-friendly fabric that can release negative ions, which has the following beneficial effects: 1. The inner support layer has a composite negative ion inner functional layer, while the outer support layer has a composite negative ion outer functional layer. The mesh of the negative ion inner functional layer and the negative ion outer functional layer are staggered. During use, moisture generated by human skin can pass sequentially through the skin-friendly layer, the mesh of the negative ion inner functional layer, the airflow gaps formed by the support layer, and finally be discharged to the outside through the staggered mesh of the negative ion outer functional layer. This circuitous path avoids the problem of the negative ion coating potentially clogging the pores between fabric fibers, affecting airflow and reducing breathability, thus ensuring the fabric's breathability and moisture-wicking function.

[0018] 2. Support layers are set on both sides of the fabric base layer. The uneven structure formed on the surface of the support layer allows for more air circulation channels between the negative ion inner functional layer and the negative ion outer functional layer and the fabric base layer, avoiding large-area contact that would affect the breathability of the inner and outer sides of the fabric base layer.

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0022] like Figures 1 to 3 As shown in the figure, the present invention provides a skin-friendly fabric that can release negative ions, including a fabric base layer 1, with an inner negative ion functional layer 3 and an outer negative ion functional layer 4 respectively provided on both sides of the fabric base layer 1, and a support layer 2 provided between the inner negative ion functional layer 3 and the outer negative ion functional layer 4 and the fabric base layer 1. A skin-friendly layer 5 is provided on one side of the inner negative ion functional layer 3. The surface of the support layer 2 is set as a non-flat structure. The inner negative ion functional layer 3 and the outer negative ion functional layer 4 are both porous mesh structures with negative ion materials attached. The mesh of the inner negative ion functional layer 3 and the mesh of the outer negative ion functional layer 4 are staggered on the projection perpendicular to the plane of the fabric base layer 1.

[0023] The base layer 1 of the fabric serves as the intermediate supporting framework, while the support layer 2 is a fabric with a textured surface, forming an airflow gap between it and the base layer 1 after lamination. The inner support layer 2 is laminated with an inner negative ion functional layer 3, while the outer support layer 2 is laminated with an outer negative ion functional layer 4. The mesh of the inner negative ion functional layer 3 and the outer negative ion functional layer 4 are staggered. During use, moisture generated by human skin can sequentially pass through the skin-friendly layer 5, the mesh of the inner negative ion functional layer 3, the airflow gap formed by the support layer 2, and finally be expelled to the outside through the staggered mesh of the outer negative ion functional layer 4. This circuitous path avoids the problem of the negative ion coating potentially clogging the pores between fabric fibers, affecting airflow and reducing breathability, thus ensuring the fabric's breathability and moisture-wicking function.

[0024] The negative ion inner functional layer 3 includes multiple first warp layers 31 and multiple first weft layers 32. The first warp layers 31 and the first weft layers 32 are interwoven to form a first shielding portion 33 and a first vent 34. A first negative ion coating 35 is provided on the surface of each of the multiple first warp layers 31 and the multiple first weft layers 32. The negative ion outer functional layer 4 includes multiple second warp layers 41 and multiple second weft layers 42. The second warp layers 41 and the second weft layers 42 are interwoven to form a second shielding portion 43 and a second vent 44. A second negative ion coating 45 is provided on the surface of each of the multiple second warp layers 41 and the multiple second weft layers 42. The second shielding portion 43 is aligned with the first vent 34, and the second vent 44 is aligned with the first shielding portion 33.

[0025] The negative ion inner functional layer 3 is made of a first warp layer 31 and a first weft layer 32 interwoven together, and forms periodic first shielding portions 33 and first venting holes 34 within the layer. The first warp layer 31 and the first weft layer 32 are covered with a first negative ion coating 35, and the released negative ions can directly act on the skin surface. The negative ion outer functional layer 4 is located outside the negative ion inner functional layer 3, and is made of a second warp layer 41 and a second weft layer 42 interwoven together. It forms periodic second shielding portions 43 and second venting holes 44 within the layer. The surfaces of the second warp layer 41 and the second weft layer 42 are covered with a second negative ion coating 45, which can synergistically release negative ions under light catalysis.

[0026] The second shielding part 43 is aligned horizontally with the first vent 34, and the second vent 44 is also aligned with the first shielding part 33. Body surface moisture can be exhausted to the outside through the first vent 34 and the second vent 44, while still ensuring smooth airflow. This avoids the problem of the negative ion coating being directly applied to the fabric surface and potentially affecting breathability, thus achieving both negative ion release function and wearing comfort.

[0027] The support layer 2 includes a fabric layer 21 and uneven portions 22 provided on the surface of the fabric layer 21. The support layer 2 is a ribbed fabric.

[0028] Ribbed fabric is a typical double-knitted structure, characterized by the alternating arrangement of front and back loops. This creates a unique appearance where the fabric, under its natural state, exhibits alternating textures 22 and fabric layers 21 due to the elasticity and bending of the yarns. This textured structure formed by the rib knit allows for more airflow channels between the inner and outer negative ion functional layers 3 and 4 and the base fabric 1, preventing large-area contact that could affect the breathability of both the inner and outer sides of the base fabric 1.

[0029] The first negative ion coating 35 is made of tourmaline or kiwistone. The second negative ion coating 45 is made of photocatalytic material. The first negative ion coating 35 uses ultrafine powder of natural minerals tourmaline or kiwistone, which can continuously release negative ions beneficial to the human body. When the fabric experiences slight friction or vibration due to human movement, it can effectively stimulate and release a high concentration of negative ions, thereby improving the microscopic air environment around the wearer and enhancing comfort. Based on this, the second negative ion coating 45 is preferably nano-titanium dioxide. The photocatalytic material, under visible or ultraviolet light irradiation, can produce a strong catalytic effect, also stimulating the generation of negative ions, and works synergistically with the first negative ion coating 35 to enhance the total amount and persistence of negative ion release.

[0030] The base layer 1 is made of woven or knitted fabric. Depending on the product's performance requirements, woven, knitted, or non-woven materials can be flexibly selected. For example, when high dimensional stability, stiffness, and strength are required, plain weave or twill woven fabrics can be used as the base layer; when excellent elasticity, extensibility, and soft, wrapping feel are required, weft-knitted or warp-knitted fabrics can be used as the base layer. The skin-friendly layer 5 is also made of woven or knitted fabric. Priority considerations for the skin-friendly layer 5 include moisture absorption, breathability, and non-irritating properties. Materials such as combed cotton, modal, and Tencel are typically used to ensure a comfortable wearing experience.

[0031] The second warp layer 41 and the second weft layer 42 are made of polyester or nylon. As the outer layer, the second warp layer 41 and the second weft layer 42 balance breathability and durability. The first warp layer 31 and the first weft layer 32 are made of breathable fabric. The inner first warp layer 31 and the first weft layer 32 can be made of softer, moisture-wicking and quick-drying breathable fabric (such as cotton, modal, etc.) to allow for breathability and moisture wicking.

[0032] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: The base layer 1 of the fabric serves as the intermediate support framework, while the support layer 2 is a textured fabric that forms an airflow gap between itself and the base layer 1 after lamination. The inner support layer 2 is laminated with an inner negative ion functional layer 3, while the outer support layer 2 is laminated with an outer negative ion functional layer 4. The mesh of the inner negative ion functional layer 3 and the outer negative ion functional layer 4 are staggered. During use, moisture generated by human skin can sequentially pass through the skin-friendly layer 5, the mesh of the inner negative ion functional layer 3, the airflow gap formed by the support layer 2, and finally be expelled to the outside through the staggered mesh of the outer negative ion functional layer 4. This circuitous path avoids the potential problem of the negative ion coating clogging the pores between fabric fibers, affecting airflow and reducing breathability, thus ensuring the fabric's breathability and moisture-wicking function. The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
