TECHNICAL FIELD
[0001] The present application relates to the technical field of clothing, in particular to a renewable non-iron shirt and a preparation method thereof. BACKGROUND
[0002] With the large use and improper disposal of plastic products worldwide, the problem of marine plastic pollution is becoming increasingly serious. A large amount of plastic garbage enters the ocean every year, causing serious damage to the marine ecosystem and threatening the survival of marine life, and also having a potential impact on human health through the food chain. Plastic bottles in a specific area 50 kilometers from the coastline have a high risk of flowing into the ocean due to factors such as water flow and wind power, becoming one of the important sources of marine plastic pollution. With the continuous improvement of environmental awareness, consumers' demand for sustainable and environmentally friendly products is growing. At the same time, in the fast-paced modern life, people hope that clothing can be more convenient and easy to maintain.
[0003] However, traditional shirts have many limitations in terms of materials and functions. In terms of materials, conventional textile raw materials such as cotton and ordinary polyester fibers are commonly used. Cotton shirts are comfortable, but have poor shape retention and are prone to deformation after washing, and consume a lot of resources. Ordinary polyester fiber shirts have certain shape retention, but the production process may cause significant pressure on the environment and lack sustainability. In terms of function, traditional shirts generally have the problem of wrinkling after washing, which requires consumers to spend a lot of time and effort on ironing, causing inconvenience in daily life.
[0004] Therefore, it is of great practical significance to develop a shirt that is both environmentally friendly and has a non-iron function, which can meet the urgent demand for environmentally friendly and convenient clothing in the market. SUMMARY
[0005] The present application aims to combine the recycling of marine plastics with the convenient wearing characteristics of clothing to meet the needs of environmental protection and practicality. A shirt made of marine regenerated polyester fiber yarn and having a non-iron function is developed to combine the recycling of marine plastics with the convenient wearing characteristics of clothing to meet the needs of environmental protection and practicality.
[0006] The present application is implemented as follows: A renewable non-iron shirt, comprising a shirt body, the shirt body comprises a back panel and two symmetrically arranged front panels, sleeves are arranged between the front and back panels, the top of the front and back panels is connected with a shoulder and a collar, and a pocket is arranged on the front panel. The shirt body is made of a new environmentally friendly shirt fabric, and the new environmentally friendly shirt fabric comprises a renewable layer, and a non-iron treatment layer is coated on the surface of the renewable layer.
[0007] As an embodiment of the present application, the renewable layer is woven from marine regenerated polyester fiber yarn.
[0008] As one embodiment of the present invention, the above-mentioned wrinkle-free treatment layer is composed of a wrinkle-free finishing agent and polyester fiber molecules cross-linked together.
[0009] A method for preparing a renewable wrinkle-free shirt includes the following steps: S1 Material Collection: Set up several collection points within an area 20-50 kilometers from the coastline to collect plastic bottles that pose a high risk of flowing into the ocean.

The molten polyester melt is then spun into polyester fibers using a spinning device. The diameter and length of the polyester fibers are controlled during the spinning process. S4 fiber treatment: The spun polyester fibers are twisted to increase their strength and stability. Then, multiple fibers are combined and spun into marine recycled polyester fiber yarn. The yarn thickness is adjusted according to the shirt design requirements. S5 Weaving: Based on design requirements, a weaving method is selected, and marine recycled polyester fiber yarn is woven on a loom to form the renewable base fabric for the shirt, i.e., the fabric used for the recycled layer; S6 wrinkle-free padding treatment: Wrinkle-free finishing agent is mixed with water to prepare wrinkle-free finishing solution. The recycled base fabric of the shirt is immersed in the wrinkle-free finishing solution. The immersion time and immersion temperature are adjusted according to the material and thickness of the fabric. After the immersion time is over, the excess finishing solution is squeezed out by the pressure of the rollers. S7 Drying and Shaping: Take out the impregnated fabric and put it into the dryer for drying and shaping. During the drying process, the wrinkle-free finishing agent cross-links with the polyester fiber molecules to form a stable wrinkle-free treatment layer, resulting in a new type of environmentally friendly shirt fabric 2. S8 Shirt Production: The above-mentioned new environmentally friendly shirt fabric 2 is cut and sewn according to the conventional shirt making process to make a complete renewable wrinkle-free shirt.
[0010] As one embodiment of the present invention, in S2 above: the crusher crushes the plastic bottle into plastic fragments with a diameter of 10-20 mm.
[0011] As one embodiment of the present invention, in S5 above, the weaving method is any one of plain weave, twill weave, or satin weave.
[0012] As one embodiment of the present invention, in S5 above: during the weaving process, the thickness and surface roughness of the fabric are controlled by adjusting the density and tension of the yarn.
[0013] As one embodiment of the present invention, in S6 above: the immersion temperature is controlled at 40-60°C and the immersion time is 5-15 minutes.
[0014] As an embodiment of the present invention, in S6 above, the wrinkle-free finishing agent and water are mixed at a mass ratio of 1:50-500 to form a uniform wrinkle-free finishing liquid. The wrinkle-free finishing agent is a polycarboxylic acid type formaldehyde-free wrinkle-free finishing agent.
[0015] In one embodiment of the present invention, in S7 above, the drying temperature is 80-0°C and the drying time is 10-30 minutes.
[0016] The beneficial effects of this invention are: 1. The raw materials for this invention are derived from plastic bottles that may flow into the ocean. By recycling and reusing these waste bottles, marine plastic pollution is reduced, and resource recycling is achieved. Simultaneously, the entire production process is traceable, ensuring that the source of raw materials and the processing meet environmental standards, making it a sustainable raw material. 2. The fabric of this invention has good shape retention, which can maintain the shape of the shirt during wearing and washing, and is not easily deformed, thus extending the service life of the shirt. It also has strong quick-drying properties, which can dry quickly in humid environments, reducing discomfort when wearing it, and is especially suitable for wearing in sports, travel and other scenarios.
[0017] 3. A wrinkle-free treatment layer is formed on or inside the fabric using a wrinkle-free finishing agent. This layer interacts with fiber molecules, altering the surface properties of the fibers and reducing friction and entanglement between them, thus maintaining the fabric's smoothness after washing. The wrinkle-free treatment layer is evenly distributed across the fabric and does not affect its breathability or comfort. Attached Figure Description
