Description

Technical Field

[0001] The invention belongs to the field of synthetic leather manufacturing for seats, and in particular relates to a closed conduction composite synthetic leather. Background Art

[0002] Natural leather is widely used in the production of daily necessities and industrial products due to its excellent natural properties. However, with the growth of the world's population, human demand for leather has doubled, and the limited amount of natural leather has long been unable to meet people's needs; polyurethane synthetic leather is popular for its excellent performance, service life, and feel. Now, in order to improve the quality of use, synthetic leather pads are generally set on the seats to improve the comfort and quality of use. Synthetic leather cushions are generally thicker and are composed of a synthetic leather surface layer and a bottom elastic layer. However, synthetic leather cushions are often inflexible in use due to different seasons. In summer, the temperature is generally high. Generally, vents are opened on the entire synthetic leather for ventilation to improve the heat dissipation performance. Once dust accumulates inside the vents when not in use, it will be very difficult to clean them later. At the same time, it will be cold in winter and uncomfortable to use. This makes synthetic leather often inflexible in use, and the season of use is limited. At the same time, long-term sitting pressure will make the synthetic leather flat and concave, and the structure will be irreversibly damaged. For this reason, it is necessary to improve the flexibility of the structure, improve the comfort of use and prevent deformation. Summary of the invention

[0005] Furthermore, a V-shaped pressure-receiving opening is provided at the outer end of the expandable opening-type penetration marking line; the guide tube has a conical structure in appearance, and the small end of the guide tube corresponds to the V-shaped pressure-receiving opening.

[0010] Furthermore, the breathable surface layer and the closed surface layer are both made of polyurethane material.
