The Difference Between Superfiber, Synthetic Leather And PU

1. Different materials

Microfiber is the abbreviation of superfine fiber PU synthetic leather. It is a non-woven fabric made of superfine fiber staple fiber through carding and needle punching to make a three-dimensional structure network, and then wet processing, PU resin impregnation, alkali weight reduction, dermabrasion dyeing and finishing And other processes finally made superfine fiber leather.

Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer and the microporous polyurethane layer is used as the granular surface layer.

PU is the abbreviation of polyurethane, the English name is polyurethane, which is a kind of polymer material. Polyurethane is an emerging organic polymer material, known as the “fifth largest plastic.”

2. Different application areas

Microfiber has a wide range of applications. Microfiber has better physical properties than leather and has a stable surface, making it almost replace leather. It is widely used in clothing coats, furniture sofas, decorative soft bags, gloves, car seats, and car interiors. Decorations, photo frames and albums, notebook skins, protective covers for electronic products and daily necessities, etc.

Synthetic leather is very similar to leather on the front and back, and has a certain degree of air permeability. It is closer to natural leather than ordinary artificial leather. It is widely used in the production of shoes, boots, bags and balls.

PU is widely used in many areas of the national economy, and product applications involve light industry, chemicals, electronics, textiles, medical treatment, construction, building materials, automobiles, national defense, aerospace, aviation, etc.

3. The main performance is different

Microfiber is the addition of ultrafine fibers to PU polyurethane, which further enhances the toughness, air permeability and abrasion resistance; it has extremely excellent wear resistance, excellent cold resistance, air permeability, and aging resistance.

There are many types of synthetic leather. In addition to the common characteristics of synthetic fiber non-woven fabric base and polyurethane microporous surface layer, all kinds of synthetic leather have different non-woven fiber varieties and processing techniques. They are different in chemical resistance, quality uniformity, It surpasses natural leather in terms of adaptability to large-scale production and processing, as well as water resistance and mildew resistance.

PU has the advantages of low density, soft texture, good stability and long storage life; excellent wear resistance and flexural resistance; excellent shock absorption and anti-slip properties; good temperature resistance; and no water absorption or water penetration , No deformation, and anti-mildew.
