Natural leather

Because of its excellent natural properties, it has been widely used in the production of daily necessities.

industrial products

However, with the growth of world population, the demand for leather has doubled, and the limited number of natural leather has long been unable to meet people's needs.

To solve this problem, scientists began to study artificial leather and synthetic leather decades ago to make up for the shortage of natural leather.

Over the past 50 years, the process of research and history is the challenge of artificial leather and synthetic leather to natural leather.

Scientists began to study nitrification and nitrification from the chemical composition and structure of natural leather.

fibre

The varnished cloth begins to enter the PVC artificial leather, the first generation of artificial leather.

Scientists have made many improvements and explorations on this basis, first of all, the improvement of the substrate, followed by the modification and improvement of the coating resin.

By 1970s, the process of needling and netting of non-woven fabrics made of synthetic fibers made the base material have lotus shaped section and hollow fiber like structure, and achieved the porous structure, which accords with the requirements of the mesh structure of natural leather. At that time, the surface of synthetic leather has been able to achieve micro pore structure polyurethane layer, which is equivalent to the surface of natural leather, so that the appearance and inner structure of PU synthetic leather are approaching to natural leather. Other physical properties are close to the index of natural leather, and the color is more vivid than natural leather. Its temperature resistance is more than 1 million times, and its natural temperature can also reach the level of natural leather at low temperature.

The emergence of microfiber PU synthetic leather is the third generation of artificial leather.

The non-woven fabric of its three-dimensional structure network is synthetic leather, which creates the conditions for catching up with natural leather in the substrate.

The product combines the newly developed PU slurry with open hole structure and the processing technology of composite surface layer, which has played a role in the super surface area and strong water absorption of superfine fiber. The ultra-fine PU synthetic leather has the inherent hygroscopic characteristics of the natural leather of the bundle like ultrafine collagen fiber, so it can match the high-grade natural leather in terms of the internal microstructure, the appearance and texture and the physical comfort of people.

In addition, the superfine fiber synthetic leather is superior to natural leather in chemical resistance, uniformity of quality, adaptability to production and processing, waterproof, mould and denaturation.

Practice has proved that the excellent properties of synthetic leather can not be replaced by natural leather. From the market analysis at home and abroad, synthetic leather has also replaced natural leather with insufficient resources.

The use of synthetic leather and synthetic leather for bags, garments, shoes, vehicles and furniture decoration has been increasingly recognized by the market. Its wide application range, large quantity and variety are the traditional natural leather which can not be satisfied.
