Artificial leather has developed into a rich category, which can be mainly divided into three categories: PVC artificial leather, PU artificial leather and PU synthetic leather.
-PVC artificial leather
Made of polyvinyl chloride (PVC) resin, it simulates the texture and appearance of natural leather, but is more wear-resistant, water-resistant and aging-resistant than natural leather. Due to its relatively low price, it is widely used in shoes, bags, furniture, car interiors and other fields. However, PVC artificial leather uses a large number of toxic additives such as stabilizers and plasticizers during processing, so it is less environmentally friendly.
-PU artificial leather
PU artificial leather is an artificial leather made of polyurethane resin as raw material. Its appearance and touch are similar to genuine leather. It has a soft texture, good elasticity, good durability and waterproofness. Due to its excellent performance, PU artificial leather is widely used in clothing, shoes, bags, furniture and other fields. Compared with PVC artificial leather, PU artificial leather is more environmentally friendly because it uses fewer additives in its production process and can be recycled.
-PU synthetic leather
PU synthetic leather is an artificial leather made of polyurethane resin as a coating and non-woven or woven fabric as a base material. Due to its smooth surface, light texture, good air permeability and wear resistance, it is widely used in sports equipment, shoes, clothing and other fields. Compared with PVC artificial leather and PU artificial leather, PU synthetic leather is more environmentally friendly because its base material can be recycled and reused, and fewer additives are used in the production process.
There are certain differences in the application fields of these three artificial leathers. PVC artificial leather is mainly used in products that require lower costs; PU artificial leather is widely used in clothing, footwear and other fields; and PU synthetic leather is more suitable for products that require high strength and high wear resistance, such as sports equipment.
According to different processes and materials, PU leather can also be divided into fully water-based PU, microfiber leather, etc. They all have very outstanding advantages and meet the diverse market demands of today's pursuit of environmental protection and beauty.
-Fully water-based PU leather
Environmentally friendly, it is made of water-based polyurethane resin, wetting and leveling agent, and other water-based auxiliary agents, processed by special water-based process formula and water-based environmentally friendly dry hair line for different fabric substrates and related auxiliary environmentally friendly equipment
-Five major advantages:
1. Good wear and scratch resistance
It is not a problem to wear and scratch more than 100,000 times, and the wear and scratch resistance of water-based polyurethane
Due to the water-based surface layer and auxiliary agents, its wear and scratch resistance has been doubled, so it is more than 10 times more wear and scratch resistance than ordinary wet synthetic leather products
2. Super long hydrolysis resistance
Compared with the traditional solvent wet bass sofa leather, all water-based high-molecular polyurethane materials are used, which has super durable hydrolysis resistance up to 8 More than 10 years
3. Skin-friendly and delicate touch
The full water-based leather has a full fleshy feel and has the same touch as genuine leather. Due to the unique hydrophilicity of water-based polyurethane and the excellent elasticity after film formation, the leather surface made by it is more skin-friendly
4. High color fastness, yellowing resistance and light resistance
Bright and transparent colors, excellent color fixation, breathable, waterproof and easy to care for
5. Healthy and environmentally friendly
Water-based ecological sofa leather does not contain any organic solvents from bottom to top, the product is odorless, and the SGS test data shows 0 formaldehyde and 0 toluene, which fully complies with EU environmental standards. It is skin-friendly to the human body and is the most ecologically healthy product among the current synthetic leather products.
-Microfiber leather
The full name of microfiber leather is "microfiber reinforced leather", which can be said to be the most technologically advanced artificial leather at present. High-quality microfiber leather combines many advantages of genuine leather, is stronger and more durable than genuine leather, is easy to process, and has a high utilization rate.
Because the base fabric is made of microfiber, it has good elasticity, high strength, soft feel, and good breathability. Many physical properties of high-end synthetic leather have exceeded those of natural leather, and the external surface has the characteristics of natural leather. In industrial terms, it is suitable for modern large-scale production, while protecting the ecology, reducing environmental pollution, making full use of non-natural resources, and having original skin characteristics on the surface. Microfiber leather can be said to be an ideal substitute for genuine leather.
-Advantages
1. Color
Brightness and other aspects are better than natural leather
It has become an important direction for the development of contemporary synthetic leather
2. Extremely similar to genuine leather
The constituent fibers are only 1% of human hair, the cross-section is very close to genuine leather, and the surface effect can be consistent with genuine leather
3. Excellent performance
The tear resistance, tensile strength and wear resistance are all better than genuine leather, and the room temperature bending reaches 200,000 times without cracks, and the low temperature bending reaches 30,000 times without cracks
Cold-resistant, acid-resistant, alkali-resistant, non-fading and hydrolysis-resistant
4. Lightweight
Soft and smooth with excellent hand feel
5. High utilization rate
The thickness is uniform and neat, and the cross-section is not worn. The leather surface utilization rate is higher than that of genuine leather
6. Environmentally friendly and non-toxic
It does not contain eight heavy metals and other substances that are harmful to humans, and it can better meet the needs of most people, so microfiber has always been popular in the artificial leather market
-Disadvantages
1. Poor breathability. Although it retains the characteristics of cowhide, its breathability is still inferior to that of genuine leather
2. High cost
