Description

Technical Field

[0001] This application relates to the field of fabrics, and more particularly to a high-barrier, biodegradable, and waterproof fabric. Background Technology

[0002] Polyester fabric, a commonly used material, has excellent strength, elasticity, and heat resistance. It is not easy to wrinkle and is not easily deformed once formed. However, polyester fabric is not easily degraded, and discarded polyester fabric will exist in the natural environment for a long time, which can easily cause pollution to the natural environment and needs to be improved. Utility Model Content

[0003] To improve the biodegradability of polyester fabrics, this application provides a high-barrier biodegradable waterproof fabric.

[0004] This application provides a high-barrier, biodegradable, and waterproof fabric, employing the following technical solution:

[0005] A high-barrier biodegradable waterproof fabric includes a first biodegradable polyester layer, a biodegradable adhesive layer, and a second biodegradable polyester layer, wherein the biodegradable adhesive layer is located between the first biodegradable polyester layer and the second biodegradable polyester layer, and the biodegradable adhesive layer connects the first biodegradable polyester layer and the second biodegradable polyester layer.

[0006] By adopting the above technical solution, a first biodegradable polyester layer, a biodegradable adhesive layer and a second biodegradable polyester layer are set, and all of the above structures are biodegradable materials, which improves the overall biodegradability and reduces the pollution to the environment after disposal.

[0007] Optionally, a barrier layer is included, located on the side of the first biodegradable polyester layer that is also away from the second biodegradable polyester layer. The barrier layer is a PET film, and the PET film has a water vapor barrier efficiency between 100-200 g / m². 2 Between 24hr and mPa.

[0008] By adopting the above technical solution and setting a barrier layer, the water vapor transmission rate is reduced, thereby improving the overall waterproof performance.

[0009] Optionally, the biodegradable adhesive layer is an acrylic adhesive layer.

[0010] By adopting the above technical solution, the fabric treated with acrylic adhesive has good waterproof performance. In addition, the strong adhesion of acrylic adhesive improves the adhesion effect and enhances the softness and elasticity of the fabric, thereby reducing the formation of wrinkles.

[0011] Optionally, the second biodegradable polyester layer has a recessed portion, and the first biodegradable polyester layer has a thickened portion, wherein the thickened portion is embedded in the recessed portion.

[0012] By adopting the above technical solution, the recessed portion and the thickened portion are provided to increase the contact area between the adhesive layer and the first biodegradable polyester layer and the second biodegradable polyester layer, thereby improving the overall connection stability. Secondly, by embedding the thickened portion into the recessed portion, the relative movement of the first biodegradable polyester layer compared to the second biodegradable polyester layer is further reduced, thereby improving the connection tightness.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. A first biodegradable polyester layer, a biodegradable adhesive layer and a second biodegradable polyester layer are provided, and all of the above structures are made of biodegradable materials, which improves the overall biodegradability and reduces the pollution to the environment after disposal;

[0015] 2. A barrier layer is installed to reduce the permeability of water vapor and improve the overall waterproof performance;

[0016] 3. The recessed and thickened portions are provided to increase the contact area between the adhesive layer and the first and second biodegradable polyester layers, thereby improving the overall connection stability. Attached Figure Description

[0020] This application discloses a high-barrier, biodegradable, and waterproof fabric. (Refer to...) Figure 1 The system includes a barrier layer 1, a first biodegradable polyester layer 2, a biodegradable adhesive layer 3, and a second biodegradable polyester layer 4. In this application, the barrier layer 1 is the outermost layer, and the second biodegradable polyester layer 4 is the innermost layer. The first biodegradable polyester layer 2 is located between the barrier layer 1 and the second biodegradable polyester layer 4, and the first biodegradable polyester layer 2 is connected to the barrier layer 1. The biodegradable adhesive layer 3 is located between the first biodegradable polyester layer 2 and the second biodegradable polyester layer 4, and the biodegradable adhesive layer 3 is connected to the first biodegradable polyester layer 2 and the second biodegradable polyester layer 4.

[0021] In this application, the barrier layer 1 is a PET membrane, and the water vapor barrier efficiency of the PET membrane is between 100-200 g / m³. 2 • Between 24hr and mPa. In practical applications, polylactic acid is added to the PET membrane material to increase its biodegradability and reduce long-term environmental pollution.

[0022] The biodegradable adhesive layer 3 is an acrylic adhesive layer. In actual use, the acrylic adhesive improves the softness and elasticity of the fabric, thereby reducing wrinkles and improving the overall wrinkle resistance.
