Description

Technical Field

[0001] The utility model belongs to the technical field of hat brims, and in particular relates to a hat brim with a multi-layer structure. Background Art

[0002] The growing popularity of outdoor activities is driving a growing demand for outdoor gear, particularly for more diverse and personalized outdoor apparel. Hats, a crucial accessory for protecting the head from direct sunlight, wind, and rain, are crucial for their design and material selection. A quality outdoor hat must not only provide basic protection but also balance comfort, aesthetics, and environmental performance to meet the diverse needs of consumers.

[0003] However, the brims of most outdoor clothing currently on the market are made of fabric and hot-melt adhesive TPU or glue combined with materials such as PP / ABS / PC plastic. Although this structure meets basic usage requirements to a certain extent, it has many shortcomings in actual application. First, because the inside of the brim is made of a harder plastic material, the overall touch is poor, and wearing it for a long time may cause discomfort to the user. Secondly, the traditional brim design has poor resilience and is prone to leaving obvious creases once squeezed or folded by external force. This not only reduces durability, but also affects the appearance and user experience.

[0004] Therefore, there is an urgent need for a multi-layered brim to solve the deficiencies of the existing technical problems. Utility Model Content

[0005] In view of the above problems, the purpose of the present invention is to provide a multi-layered brim, which has good resilience, good air permeability, stable structure and can achieve temperature regulation.

[0006] To achieve the above objectives, the utility model provides a multi-layer structure brim, including a gauze surface layer, a first honeycomb layer, a non-woven fabric layer, a second honeycomb layer, and a gauze inner layer; the gauze surface layer and the first honeycomb layer are connected by a first hot-melt adhesive layer, and the gauze inner layer is connected to the second honeycomb layer by a second hot-melt adhesive layer. The first hot-melt adhesive layer and the second hot-melt adhesive layer both have a microporous structure, the first honeycomb layer, the non-woven fabric layer, and the second honeycomb layer are all elastomers, and the first honeycomb layer and the second honeycomb layer both include multi-layer honeycomb structure layers, and the honeycombs in the multi-layer honeycomb structure layers are filled with thermal insulation particles.

[0007] Furthermore, the gauze surface layer and the gauze inner layer of the present invention are both woven with hollow yarns. The hollow yarns are light, soft and breathable, and can provide good comfort and breathability.

[0008] Furthermore, the thermal insulation particles of the present invention include at least one of aerogel particles, glass microfiber particles, ultrafine glass fiber particles and vaporized silica particles.

[0009] Furthermore, the honeycombs in the multi-layer honeycomb structure of the present invention are arranged in a staggered manner. This staggered arrangement reduces direct contact between the upper and lower honeycomb walls, further reducing heat conduction and improving thermal insulation. Furthermore, the staggered arrangement can also improve the stability of the overall structure of the brim.

[0010] Furthermore, the cross-sectional shape of the honeycombs of the multi-layer honeycomb structure layer of the present invention is hexagonal, rectangular or trapezoidal.

[0011] Furthermore, the diameters of the micropores in the first and second hot melt adhesive layers of the present invention are independently 0.1 to 5 μm. This microporous structure gives the hot melt adhesive layers a high air permeability, improving wearing comfort; it also reduces weight, making the brim of the hat more lightweight.

[0012] Furthermore, the first honeycomb layer and the second honeycomb layer of the present invention are both made of foamed TPU material.

[0013] Furthermore, the non-woven fabric layer of the present invention is a TPU meltblown non-woven fabric made of TPU material. The TPU meltblown non-woven fabric has excellent support properties, ensuring the stability of the brim shape. Furthermore, the first and second honeycomb layers can be directly hot-melt-bonded without the use of glue, simplifying the production process and improving product quality.

[0014] Furthermore, the first hot melt adhesive layer and the second hot melt adhesive layer of the utility model are TPU hot melt adhesive layers.

[0015] Compared with the prior art, the multi-layered brim of the present invention has the following beneficial effects:

[0016] 1. The first honeycomb layer, non-woven fabric layer and second honeycomb layer are all made of elastomers with good resilience. They can quickly restore the brim to its original shape without leaving creases after being subjected to external force, thereby improving wearing comfort.

[0017] 2. By filling the honeycombs of the multi-layer honeycomb structure with thermal insulation particles, the temperature inside the brim can be adjusted according to changes in ambient temperature, thereby achieving a certain degree of warmth retention or heat dissipation. Specifically, in hot weather, the brim can promote heat dissipation and reduce heat accumulation in the head, making the wearer feel cooler and more comfortable; while in cold environments, it can effectively prevent heat loss, keep the head warm, and reduce discomfort caused by wind chill.

[0018] 3. The first hot melt adhesive layer and the second hot melt adhesive layer adopt a microporous structure, combined with a multi-layer honeycomb structure layer of the first honeycomb layer and the second honeycomb layer, which ensures that the entire brim has good breathability and avoids the occurrence of sweating and discomfort on the head caused by long-term wearing.

[0019] 4. The multi-layer structure design and the use of hot-melt adhesive layer make the overall structure of the brim more stable and not easy to deform, thus extending the service life of the product. At the same time, the use of gauze as the surface and lining materials not only increases the beauty of the product, but also improves the softness and comfort of the part that directly contacts the skin.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings of the specification. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Please see Figure 1The present invention provides a multi-layered hat brim 100, comprising a gauze surface layer 11, a first honeycomb layer 13, a non-woven fabric layer 14, a second honeycomb layer 15, and a gauze inner layer 17. The gauze surface layer 11 and the first honeycomb layer 13 are connected by a first hot-melt adhesive layer 12, and the gauze inner layer 17 and the second honeycomb layer 15 are connected by a second hot-melt adhesive layer 16. The first hot-melt adhesive layer 12 and the second hot-melt adhesive layer 16 both have a microporous structure. The first honeycomb layer 13, the non-woven fabric layer 14, and the second honeycomb layer 15 are all elastomers. The first honeycomb layer 13 and the second honeycomb layer 15 both comprise multi-layered honeycomb structure layers, and the honeycombs 131 of the multi-layered honeycomb structure layers are filled with heat-insulating particles 132. The first honeycomb layer 13, the non-woven fabric layer 14, and the second honeycomb layer 15 are made of materials with good resilience, which enables the multi-layered hat brim 100 to quickly return to its original shape without leaving creases after being subjected to external forces, thereby improving wearing comfort. At the same time, by filling the honeycombs 131 of the multi-layer honeycomb structure with heat-insulating particles 132, the temperature inside the multi-layer structure brim 100 can be adjusted according to changes in the ambient temperature, thereby achieving a certain degree of warmth retention or heat dissipation effect. Specifically, in hot weather, the multi-layer structure brim 100 can promote heat dissipation to reduce heat accumulation on the head, making the wearer feel cooler and more comfortable; while in cold environments, it can effectively prevent heat loss, keep the head warm, and reduce discomfort caused by wind chill. In addition, the first hot melt adhesive layer 12 and the second hot melt adhesive layer 16 adopt a microporous structure, combined with the multi-layer honeycomb structure layer in the first honeycomb layer 13 and the second honeycomb layer 15, this ensures that the entire multi-layer structure brim 100 has good breathability, avoiding the occurrence of sweating and discomfort on the head caused by long-term wear. Furthermore, the multi-layer structure design and the use of the first hot-melt adhesive layer 12 and the second hot-melt adhesive layer 16 make the overall structure of the multi-layer structure brim 100 more stable and less prone to deformation, thereby extending the service life of the product; at the same time, gauze is used as the material for the gauze surface layer 11 and the gauze inner layer 17, which not only increases the aesthetics of the product, but also improves the softness and comfort of the part that directly contacts the skin.

[0024] Furthermore, the gauze surface layer 11 and the gauze inner layer 17 of the present invention are both woven from hollow yarns. The hollow yarns have a unique woven structure, which allows them to form more air layers during the weaving process, thereby effectively reducing heat conduction and improving overall thermal insulation performance. Furthermore, the lightweight nature of the hollow yarns also makes the multi-layered brim 100 lighter and more comfortable to wear, reducing the pressure on the head caused by prolonged wear.

[0025] Furthermore, the heat-insulating particles 132 include at least one of aerogel particles, glass microfiber particles, ultrafine glass fiber particles, and vaporized silica particles. These particles all have good heat-insulating effects and can automatically adjust the temperature inside the multi-layered hat brim 100 according to changes in ambient temperature. In order to further enhance the heat-insulating effect of the heat-insulating particles 132, the honeycombs 131 in the multi-layered honeycomb structure layer of the present invention can be as follows: Figure 2 The staggered arrangement shown in the figure can cause the honeycombs 131 of the upper layer to have a specific offset relative to the honeycombs 131' of the lower layer, resulting in a certain angle between the upper honeycombs 131 and the lower honeycombs 131', which can effectively reduce the heat conduction between the upper and lower layers of the honeycombs 131, thereby enhancing the thermal insulation effect of the thermal insulation particles 132. Therefore, even under extreme temperature conditions, the temperature of the multi-layer structure brim 100 can be regulated. More specifically, the cross-sectional shape of the honeycombs 131 of the multi-layer honeycomb structure layer is hexagonal, rectangular or trapezoidal; wherein the hexagonal honeycomb 131 can provide the highest structural stability and the greatest space utilization while maintaining a low weight, and the trapezoidal honeycomb 131 can provide different mechanical properties in different directions, such as compression resistance and tensile resistance. Therefore, combining the hexagonal and trapezoidal honeycombs 131 can ensure that the multi-layer structure brim 100 has extremely high mechanical strength and toughness while being lightweight. Therefore, the cross-sectional shape of the honeycombs 131 in the multi-layer honeycomb structure layer is preferably as follows. Figure 1 Hexagons and trapezoids shown.

[0026] Furthermore, a single-layer honeycomb structure with a thickness of about 2 mm can be stacked to obtain a multi-layer honeycomb structure layer. For example, by stacking 3 to 4 layers, a multi-layer honeycomb structure layer with a thickness of 6 to 8 mm can be obtained. This can not only reduce the overall weight of the multi-layer structure brim 100, but also ensure that the multi-layer structure brim 100 has good breathability. In addition, the number of layers of the honeycomb structure layer can be adjusted according to different application scenarios and needs. For example, for occasions requiring higher support strength, the number of layers can be increased; and for applications that pursue extreme lightweight, this can be achieved by reducing the number of layers. Specifically, the first honeycomb layer 13 and the second honeycomb layer 15 are both made of foamed TPU material. Foamed TPU is a high-performance elastomeric material with excellent resilience and wear resistance, and is lightweight and soft. The use of this material enables the multi-layer structure brim 100 to quickly return to its original shape after being subjected to external force, and is not prone to leaving creases, thereby ensuring long-term wear comfort and durability. In addition, the non-woven fabric layer 14 in the present invention is made of TPU melt-blown non-woven fabric made of TPU material. The TPU melt-blown non-woven fabric not only provides excellent support and ensures the stability of the shape of the multi-layer structure brim 100, but also because TPU can soften and flow when heated and solidify after cooling, when the first honeycomb layer 13 and the second honeycomb layer 15 are both made of foamed TPU material, there is no need to use additional glue. The first honeycomb layer 13 and the second honeycomb layer 15 can be firmly bonded by hot melting the TPU melt-blown non-woven fabric.

[0027] Furthermore, the diameter of the micropores 121 in the first hot-melt adhesive layer 12 of the present invention is controlled within the range of 0.1 to 5 μm. Of course, the diameter of the micropores in the second hot-melt adhesive layer 16 is also controlled within the range of 0.1 to 5 μm. This unique microporous structure gives the hot-melt adhesive layer excellent air permeability, with an air permeability rate of 50 to 100 mm / s, far exceeding the level of traditional hot-melt adhesive films. This means that the first hot-melt adhesive layer 12 and the second hot-melt adhesive layer 16 can not only maintain good air permeability, but also have strong bonding strength, ensuring a tight connection between the layers, and the overall weight is lighter. In particular, the first hot-melt adhesive layer 12 and the second hot-melt adhesive layer 16 of the present invention are made of TPU (thermoplastic polyurethane) hot-melt adhesive layers, which have excellent bonding properties, good flexibility and elasticity, as well as excellent weather resistance, and can be used for a long time in outdoor environments without aging.

[0028] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
