Ultrafiber leather is called "Ultrafine Fiber Reinforced PU Leather". Ultrafiber PU synthetic leather represents the development direction of artificial leather. Because it has the most similar properties of natural leather, excellent wear resistance, excellent cold resistance, air permeability and aging resistance, it is highly praised and favored by domestic and foreign famous leather designers.
Industrial production of artificial leather has a history of several decades. With the continuous application of various new materials, its products are constantly updated. Leather-based fabrics range from woven fabrics to today's non-woven fabrics, using resins ranging from polyvinyl chloride, acrylic resin to polyurethane (PU), and fibers ranging from ordinary chemical fibers to lotus-shaped fibers and superfine fibers. In terms of product style, artificial leather has gone through the development process from low-grade to high-grade, from imitation to simulation, and its characteristics even surpass natural leather.
Superfine fiber synthetic leather was developed on the basis of full analysis of natural leather. Superfine fiber synthetic leather is made of bundle superfine fibers and polyurethane by special process. It is made of nylon superfine fibers similar to those of bundle collagen fibers in natural leather, which have three-dimensional network structure, and then filled with polyurethane with open microporous structure.
The advantages of superfine fiber synthetic leather are: high tear strength, tensile strength, good flexural resistance, good cold resistance, good mildew resistance, thick and plump finished products, good simulation, low VOC content, etc. The surface is easy to clean and the structure is similar to that of natural leather.
However, it also has its shortcomings: Ultrafiber synthetic leather belongs to scientific and technological products, which is concentrated in the production of powerful enterprises at home and abroad, and has a certain monopoly, leading to high product prices.
