Description

Technical Field

[0001] This utility model relates to the field of clothing fabric technology, specifically to a breathable and warm clothing fabric. Background Technology

[0002] Clothing fabrics are the basic materials that make up clothing. Their core function is to achieve a balance of physical properties such as warmth, breathability, windproofness, waterproofness, moisture absorption, and elasticity through the coordinated design of fiber morphology, yarn structure, and fabric organization.

[0003] Currently, traditional thermal fabrics have certain shortcomings in terms of breathability. Taking common cotton fabric as an example, although cotton fibers are naturally skin-friendly and their hollow fiber structure can trap a certain amount of air, providing basic warmth, their dense fiber arrangement results in poor air circulation, thus limiting the overall breathability of the garment. Wool fabric, while possessing excellent warmth retention and its unique crimped fiber structure that traps more still air, is more prone to static electricity than cotton, leading to a decreased user experience. Therefore, we propose a breathable and warm clothing fabric to effectively address these drawbacks. Utility Model Content

[0004] The purpose of this invention is to provide a breathable and warm clothing fabric to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a breathable and warm clothing fabric, comprising a skin-contact layer, a warm layer and a windproof layer stacked from the inside to the outside, wherein the warm layer and the windproof layer are fixedly connected by a number of protrusions, and a breathable cavity is formed between the warm layer and the windproof layer, the breathable cavity being used for air storage and circulation.

[0006] Optionally, a number of the protrusions are evenly distributed between the insulation layer and the windproof layer. The upper and lower sides of the protrusions are bonded to the windproof layer and the insulation layer by hot pressing. A number of vent holes are evenly distributed on the windproof layer. The number of vent holes and the number of protrusions are staggered. The vent holes are used to connect the vent cavity.

[0007] Optionally, the skin-adhesive layer and the thermal insulation layer are bonded together by ultrasonic welding, and the thermal insulation layer is provided with conductive fibers, which are used to eliminate static electricity on the skin-adhesive layer.

[0008] Optionally, the insulation layer has a plurality of perforations evenly distributed thereon, and the conductive fibers pass through two adjacent perforations in sequence.

[0009] Optionally, the conductive fibers on the front side of the insulation layer are located inside the breathable cavity and are distributed alternately with several protrusions; the conductive fibers on the back side of the insulation layer are tightly bonded to the skin-adhesive layer.

[0010] Optionally, the skin-adhesive layer and the windproof layer are both woven from polyester and spandex fibers, and the insulating layer is woven from cotton fibers.

[0011] Compared with the prior art, this utility model provides a breathable and warm clothing fabric with the following beneficial effects:

[0012] 1. This utility model sets several sponge protrusions between the insulation layer and the windproof layer, and combines them with the ventilation holes on the windproof layer that are distributed alternately with the protrusions, so that air can enter the ventilation cavity and then be discharged, thereby enhancing the air flow between the fabrics and improving the overall breathability of the fabric.

[0013] 2. This utility model interweaves conductive fibers on the thermal insulation layer, so that the conductive fibers come into contact with the skin-contact layer. This allows the static electricity generated in the skin-contact layer to be guided into the breathable cavity by the conductive fibers, achieving the effect of quickly eliminating static electricity and improving the user's wearing experience.

[0017] 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.

[0018] Please see Figure 1 - Figure 2 A breathable and warm clothing fabric includes a skin-contact layer 1, a warming layer 2, and a windproof layer 3, which are layered from the inside to the outside. The skin-contact layer 1 and the warming layer 2 are bonded together by ultrasonic welding. High-frequency vibration causes the fabric molecules to generate heat through friction, which melts the molecules locally and then bonds them together. There is no glue residue, making it environmentally friendly and extremely breathable.

[0019] The skin-contact layer 1 and windproof layer 3 are made of jacquard fabric, consisting of 84% polyester and 16% spandex, with a weight of 80g / m². This makes the skin-contact layer 1 and windproof layer 3 lightweight yet elastic, with a smooth feel and quick-drying properties, improving the user's wearing experience. Furthermore, the surface of windproof layer 3 has an ultra-lightweight windproof membrane or a DWR water-repellent coating, giving it a certain degree of wind and water resistance.

[0020] On the other hand, the insulation layer 2 is made of woven cotton fibers. The cross-section of cotton fibers is hollow, and there are a large number of pores between the fibers. These pores can store a large amount of air. Since air has a high thermal resistance, cotton fibers can effectively prevent heat loss and form an insulation layer. At the same time, thanks to the low thermal conductivity of cotton fibers, the insulation layer 2 has a good heat retention effect.

[0021] Furthermore, the insulating layer 2 and the windproof layer 3 are fixedly connected by several protrusions 4. These protrusions 4 are evenly distributed between the insulating layer 2 and the windproof layer 3. The upper and lower sides of the protrusions 4 are bonded to the windproof layer 3 and the insulating layer 2 by hot pressing. This hot pressing process has the advantages of being strong and leaving no trace, preventing the separation of different fabric layers after prolonged use. The protrusions 4 create gaps between the insulating layer 2 and the windproof layer 3, forming a breathable cavity 5. This breathable cavity 5 allows air to be stored and circulated, increasing the space for air storage and flow within the fabric, thereby improving the fabric's breathability.

[0022] Among them, the raised dots 4 are made of silicone or sponge. Silicone can be made into a porous structure, which can improve the sweat absorption by 20% to 30%. The sponge itself has a porous structure and strong sweat absorption. It can not only absorb the sweat in the breathable cavity 5, but also make the fabric fluffier, improve the feel, and improve breathability.

[0023] In this embodiment, a plurality of vent holes 301 are evenly distributed on the windproof layer 3, and the plurality of vent holes 301 and a plurality of protrusions 4 are staggered. The vent holes 301 are used to connect the ventilated cavity 5 so that the outside wind can be blown into the ventilated cavity 5 through the vent holes 301, so that the air flow in the ventilated cavity 5 is faster and the evaporation of sweat on the insulation layer 2 and the protrusions 4 is accelerated.

[0024] It is worth mentioning that conductive fibers 6 are provided on the thermal insulation layer 2, which are used to eliminate static electricity on the skin-adhesive layer 1.

[0025] Among them, conductive fiber 6 is a composite fiber, which is made by combining conductive materials (such as metal powder, carbon black, metal oxide, etc.) into the conventional fiber matrix through physical or chemical methods. It has a low cost and combines the mechanical properties of conventional fibers with the conductivity of conductive fibers. It can be woven into fabrics to eliminate static electricity on the fabric.

[0026] Specifically, the insulation layer 2 has a number of evenly distributed perforations 201. These perforations 201 are gaps formed by the fiber weave on the insulation layer 2, and their diameter is very small. Conductive fibers 6 pass through adjacent perforations 201 in sequence, and the weaving process can be changed according to actual needs. A section of the conductive fiber 6 on the front side of the insulation layer 2 is located within the breathable cavity 5 and is interspersed with several protrusions 4. A section of the conductive fiber 6 on the back side of the insulation layer 2 is tightly bonded to the skin-adhesive layer 1, so that the static electricity generated by the skin-adhesive layer 1 in contact with the skin can be absorbed by the conductive fiber 6 on the back side of the insulation layer 2 and then transferred to various parts of the conductive fiber 6. Under the action of the electrostatic field, the air surrounding the conductive fiber 6 located in the breathable cavity 5 is ionized to form positive and negative ions. The positive ions neutralize the static charge on the fabric, while the negative ions neutralize the environment or the ground, thereby eliminating static electricity. This process can occur without grounding, and the discharge is weak and safe.

[0027] The working principle and usage process of this utility model are as follows: the skin-contact layer 1 and the windproof layer 3 are made of jacquard fabric to improve the user's wearing experience; the thermal insulation layer 2 provides warmth to the fabric; and the ventilation cavity 5 and ventilation holes 301 increase the amount of air stored and the flow of air in the fabric, making the fabric more breathable.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
