[0003] Traditional yarns are made by twisting multiple strands of fibers. The yarns can meet the requirements of high strength and high toughness, but the overall material is difficult to degrade, difficult to handle after being discarded, and easily causes environmental pollution. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that polyester yarns are difficult to degrade and easily cause environmental pollution.

[0005] To solve the above problems, the following technical solutions are adopted in the utility model: The environment-friendly recycled polyester yarn proposed by the utility model includes a polyester thread body, and also includes a core, a reinforcing rib, and a coloring layer. The core is set as a long cylindrical structure with a circular cross-section. The core is made of protein fiber material. The reinforcing rib is tightly spirally wound outside the core. A first waterproof layer is wrapped outside the core. The coloring layer is set as the outermost layer of the polyester thread body. A thin-film-like second waterproof layer is provided between the coloring layer and the reinforcing rib.

[0006] Further, there are five reinforcing ribs in total, and the five reinforcing ribs are arranged in parallel.

[0007] Further, the reinforcing rib is made of thermoplastic polyurethane fiber material.

[0008] Further, the first waterproof layer is made of polybutylene terephthalate - adipate material, and the outside of each reinforcing rib is in close fit connection with the first waterproof layer.

[0009] Further, the second waterproof layer is also made of polybutylene terephthalate - adipate material.

[0010] Further, the coloring layer is made of polybutylene terephthalate material.

[0011] The beneficial effects obtained by the utility model adopting the above structure are as follows:

[0012] By using protein fiber materials, thermoplastic polyurethane fiber materials, polybutylene terephthalate adipate materials, and polybutylene terephthalate materials for the polyester thread body, while ensuring the toughness, waterproofness, and softness and easy coloring characteristics of the overall polyester thread body, it is environmentally friendly and easily degradable after being discarded.

[0017] The drawings are used to provide a further understanding of the present utility model, and constitute a part of the specification. Together with the embodiments of the present utility model, they are used to explain the present utility model, and do not constitute a limitation to the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0019] As Figures 1 - 3 shown, an environmentally friendly recycled polyester yarn proposed by the present utility model includes a polyester thread body 1, and also includes a thread core 2, a reinforcing rib 3, and a coloring layer 6. The thread core 2 is set as a long cylindrical structure with a circular cross-section. The thread core 2 uses protein fiber materials. The reinforcing rib 3 is tightly spirally wound around the outside of the thread core 2. The outside of the thread core 2 is wrapped with a first waterproof layer 4. The coloring layer 6 is set as the outermost layer of the polyester thread body 1. A thin-film-shaped second waterproof layer 5 is provided between the coloring layer 6 and the reinforcing rib 3.

[0020] As Figure 1 and Figure 3 shown, there are a total of five reinforcing ribs 3. The five reinforcing ribs 3 are arranged in parallel. The reinforcing rib 3 uses thermoplastic polyurethane fiber materials. Thermoplastic polyurethane materials have the characteristics of high elasticity, strong durability, and degradability.

[0021] As Figures 1 - 3As shown, the first waterproof layer 4 is made of polybutylene terephthalate adipate material. The outer side of each reinforcing rib 3 is adhesively connected to the first waterproof layer 4. The polybutylene terephthalate adipate material has good waterproof performance while taking into account degradability and flexibility. The second waterproof layer 5 is also made of polybutylene terephthalate adipate material.

[0022] As Figures 2 - 3 shown, the coloring layer 6 is made of polybutylene terephthalate material. The polybutylene terephthalate material has good spinnability, a soft handfeel, high bulkiness, and easy dyeability, and is also easily degradable.

[0023] In specific use, the core 2 made of protein fiber material is used as the main strength structure of the polyester thread body 1, which can ensure the overall high stiffness and toughness of the polyester thread body 1 while having the advantages of breathability and easy degradability. The reinforcing ribs 3 wound around the outside of the core 2 are made of thermoplastic polyurethane fiber material, which is easy to decompose after being discarded while increasing the strength and elasticity of the polyester thread body 1. The first waterproof layer 4 made of polybutylene terephthalate adipate material with both degradability and flexibility is wrapped around the outside of each reinforcing rib 3, and the second waterproof layer 5 made of polybutylene terephthalate adipate material is provided between the coloring layer 6 and the reinforcing rib 3, which can ensure the overall waterproofness and degradability of the polyester thread body 1. The coloring layer 6 wrapped around the outside of the polyester thread body 1 is made of polybutylene terephthalate material, which is easy to color while ensuring the overall soft touch of the polyester thread body 1, facilitating the coloring of the polyester thread body 1 into various colors to ensure aesthetics, and also having the characteristic of easy degradability.

[0024] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative concept of the present invention, they shall fall within the protection scope of the present invention.
