1, Resistance to twists and turns: as excellent as natural leather, no cracks in 200,000times twists at normal temperature, 30,000times no craks at -20℃.
2, Appropriate elongation percentage(good leather touchl)
3, High tear and peel strength(High wear/tear resistance / strong tensile strength)
4, Not fenerate any pollution from production to usage, environment friendly.
Microfibers looks most likely genuine leather. While the uniformity of thickness, tear strength, rich colors, utilization of material are superior than genuine leather, is the future trend of synthetic leather. Can use high-grade petrol or pure water to clean it if there is any dirty on mifrofiber surface, but prohibit it to clean with organic solvents or anything with alkaline which will affect the quality. Application condition: No more than 25min during 100℃ heat-setting temperature, 10min at 120℃, 5min at 130℃.
Because of its excellent natural characteristics, it is widely used in the production of daily necessities and industrial products. However, as the world’s population grows, human demand for leather has doubled, and the limited amount of natural leather has long been unable to meet people’s needs. In order to solve this contradiction, scientists began to research and develop artificial leather and synthetic leather decades ago to make up for the shortcomings of natural leather. The historical process of more than 50 years of research is the process of artificial leather and synthetic leather challenging natural leather.
Scientists started by research and analyzing the chemical composition and organizational structure of natural leather, starting with nitrocellulose varnished cloth, and entering PVC artificial leather, which is the first generation of artificial leather. On this basis, scientists have made many improvements and explorations, first the improvement of the substrate, and then the modification and improvement of the coating resin. In the 1970s, the synthetic fiber non-woven fabrics were needle punched into nets, bonded into nets, etc., so that the base material had a lotus-shaped section, hollow fiber shape, and reached a porous structure, which was in line with the net structure of natural leather. Requirement; At that time, the surface layer of synthetic leather can achieve a micro-porous structure polyurethane layer, which is equivalent to the grain of natural leather, so that the appearance and internal structure of PU synthetic leather are gradually close to that of natural leather, and other physical properties are close to those of natural leather. Index, and the color is more bright than natural leather; its normal temperature folding resistance can reach more than 1 million times, and low temperature folding resistance can also reach the level of natural leather.
Following PVC artificial leather, PU synthetic leather has been researched and developed by scientific and technological experts for more than 30 years. As an ideal substitute for natural leather, PU synthetic leather has achieved breakthrough technological progress.
