Description

Technical Field

[0001] This utility model relates to the field of automotive interior materials technology, specifically to an environmentally friendly recycled nonwoven cotton material structure. Background Technology

[0002] In recent years, with the booming development of the automotive industry, the production of automotive interior fabrics has also grown rapidly. Textiles account for nearly half of the materials used in automotive interiors. Automotive textiles mainly include woven fabrics, knitted fabrics, nonwoven fabrics, and fiber composites, with woven fabrics and knitted fabrics being the two main categories.

[0003] Chinese Patent Application No. 202120723925.4 discloses an automotive interior material comprising a first resin layer, a woven layer, and a second resin layer sequentially disposed therefrom; wherein the woven layer is a polyetheretherketone (PEEK) woven layer. The automotive interior material provided by this invention exhibits good weather resistance and stability under varying temperatures and humidity conditions; it also boasts low cost and a woven-look visual effect, enhancing the aesthetics of the interior material.

[0004] Current automotive interior materials have poor flame-retardant properties, resulting in rapid combustion and the release of large amounts of harmful gases. This can lead to passengers being exposed to toxic fumes and losing consciousness during a fire, hindering escape. Therefore, there is an urgent need to design an environmentally friendly recycled nonwoven cotton material structure to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly recycled nonwoven cotton material structure to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An environmentally friendly recycled nonwoven cotton material structure includes a flame-retardant layer, a surface layer on one side of the flame-retardant layer, a pile layer on one side of the surface layer, an adhesive layer between the surface layer and the flame-retardant layer, and uniformly distributed cavities on the outer wall of the flame-retardant layer near the adhesive layer.

[0008] Furthermore, a mesh layer is bonded to one side of the outer wall of the flame-retardant layer, and the mesh layer is located on the side of the flame-retardant layer away from the bonding layer.

[0009] Furthermore, the flame-retardant layer is non-woven cotton, and the thickness of the flame-retardant layer is 5-20mm.

[0010] Furthermore, the thickness of the surface layer is 0.5-0.8 mm, and the surface layer is made of polyester microfiber.

[0011] Furthermore, the outer layer is a warp-knitted suede-like fabric, and the linear density of the polyester microfiber in the outer layer is 56-220 dtex.

[0012] In the above technical solution, the environmentally friendly recycled non-woven cotton material structure provided by this utility model has the following beneficial effects: the surface layer is formed by impregnating microfiber imitation suede with flame retardant, and then high flame retardant environmentally friendly non-woven cotton is glued to the back. On the one hand, it can improve the fire resistance of the fabric, and on the other hand, it will not release organic matter that is harmful to the human body when a fire occurs, which helps to improve the safety performance of the car and reduce the damage caused by the fire to passengers and the vehicle. At the same time, the soft and delicate surface effect of microfiber imitation suede makes the interior space of the car more upscale and luxurious, combining the dual value of performance and appearance.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-2 As shown in the figure, the present invention provides an environmentally friendly recycled nonwoven cotton material structure, including a flame-retardant layer 1, a surface layer 2 on one side of the flame-retardant layer 1, a fluff layer 3 on one side of the surface layer 2, an adhesive layer 5 between the surface layer 2 and the flame-retardant layer 1, and uniformly distributed cavities 6 on the outer wall of the side of the flame-retardant layer 1 near the adhesive layer 5.

[0020] Specifically, in this embodiment, a flame-retardant layer 1 is included, with a thickness of 5-20mm. The flame-retardant layer 1 is non-woven cotton that has been treated with flame retardants to form highly flame-retardant non-woven cotton. Furthermore, the flame-retardant layer 1 made of non-woven cotton can be recycled, achieving an environmentally friendly effect. A surface layer 2 is provided on one side of the flame-retardant layer 1. The surface layer 2 is a warp-knitted imitation suede fabric made of polyester microfiber. A pile layer 3 is provided on one side of the surface layer 2. The pile layer 3 is formed by napping the surface layer 2. The linear density of the polyester microfiber in the surface layer 2 is...

[0021] The linear density is 56-220 dtex. When the linear density is less than 56 dtex, the napping density is low, and a good appearance effect cannot be achieved. When the linear density is greater than 220 dtex, the resistance of the needle cloth during napping increases, resulting in a rough appearance surface. An adhesive layer 5 is provided between the surface layer 2 and the flame retardant layer 1. It is an environmentally friendly adhesive used in existing fabric composites. The outer wall of the flame retardant layer 1 near the adhesive layer 5 has uniformly distributed cavities 6. The adhesive layer 5 can fill the cavity 6 through the cavity 6, increasing the bonding area and improving the bonding strength.

[0022] This utility model provides an environmentally friendly recycled non-woven cotton material structure, which forms a surface layer 2 by impregnating microfiber imitation suede with flame retardant, and then bonding highly flame-retardant environmentally friendly non-woven cotton to the back. On the one hand, it can improve the fire resistance of the fabric, and on the other hand, it will not release organic matter harmful to the human body in the event of a fire, which helps to improve the safety performance of the car, reduce the damage to passengers and vehicles caused by fire, and make it easier for people inside the car to escape. At the same time, the soft and delicate surface effect of microfiber imitation suede makes the car interior space more upscale and luxurious, combining the dual value of performance and appearance.

[0023] In another embodiment of this utility model, a mesh layer 4 is bonded to one outer wall of the flame-retardant layer 1. The mesh layer 4 is made of nylon material and is located on the side of the flame-retardant layer 1 away from the adhesive layer 5. The flame-retardant layer 1 improves the overall tensile strength of the material. The preferred thickness of the flame-retardant layer 1 is 10mm, which makes the material more moderately soft when applied to automotive interiors. The thickness of the surface layer 2 is 0.5-0.8mm, and the preferred thickness of the surface layer 2 is 0.8mm, which gives the surface layer 2 a more ideal soft and delicate feel.

[0024] Working principle: A surface layer 2 is formed by impregnating microfiber suede-like material with a 5% HTA flame-retardant solution. Then, a flame-retardant layer 1, formed by highly flame-retardant and environmentally friendly non-woven cotton, is glued to the back. The following points should be noted for this composite process: Uniformity control of the adhesive: Currently, the latest adhesive mixing equipment is used. The hot melt adhesive is stirred in the mixing tank and passed through a new type of nano-level high-tech filter to make the solution more uniform and smooth, while maintaining the molecular properties within the solution, resulting in a smoother and more uniform application of the hot melt adhesive; Temperature control of the adhesive: Generally, the adhesive temperature is controlled at 110℃±10℃ to ensure the adhesive's viscosity and uniformity, allowing for better adhesion to the suede-like material; The finished composite product needs to be maintained at a temperature of 15℃ or higher. The material is cured in an environment with a temperature and humidity maintained above 40% for more than 24 hours to ensure the bonding strength between the surface layer and the non-woven cotton, giving it a high flame retardant effect (horizontal burning not lower than B, vertical burning ≤100mm / min, and smoke density SDR≤75). On the one hand, it can improve the fire resistance of the fabric, and on the other hand, it will not release organic substances harmful to the human body in the event of a fire. When this material is used in automotive interiors, it helps to improve the safety performance of the car and reduce the damage caused by fire to passengers and vehicles. At the same time, the soft and delicate surface effect of the microfiber imitation suede makes the car interior space more upscale and luxurious, combining the dual value of performance and appearance.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
