How to make clothes from thermoplastic materials

The present invention relates to a method of manufacturing clothes, in particular to a method of manufacturing clothes using thermoplastic materials.

Thermoplastic materials have excellent injection molding properties, mechanical properties, heat resistance, and electrical resistance properties. They are often used to form various mechanical structures. They can also be processed into fabrics and further made into clothes to provide a variety of clothing styles.

Although the manufacturing technology of clothes has been developed for many years, there are still several difficulties encountered when manufacturing clothes:

1. The production speed of clothes is slow: Early clothing processing technology required cutting with a knife and then sewing with a needle and thread. Although tailoring machines have been developed that can quickly sew clothes, the length of the line cut by the scissors and the moving speed of the thread and needle thread are limited. The production speed has been limited and cannot be further accelerated.

2. Unable to provide better comfort: The fabrics made of thermoplastic materials used in the early days were thick and did not have a breathable structure. When the clothes were worn on the body, the human body would feel abnormally hot due to the non-breathable fabrics, which had the disadvantage of being uncomfortable to wear.

3. The manufacturing process is cumbersome: Some clothes are equipped with buttons or zippers. Early buttons and zippers also used sewing technology and needed to be sewn separately, making the manufacturing process of clothes cumbersome.
