PVC artificial leather is the first generation of artificial leather.

It is a imitation leather product based on textile or knitted material and polyvinyl chloride resin.

Its characteristics are similar to natural leather, bright appearance, soft texture, wear resistance, folding resistance, acid and alkali resistance, etc.

Since the 70s of last century, after more than 20 years of development, it has developed to a fairly large scale. However, due to its poor air permeability and hygroscopicity, it has been restricted in recent years. With the development of PU synthetic leather, especially the advent of the third generation of artificial leather and microfiber leather, the development of artificial leather has been pushed to a new level of higher level. PVC artificial leather is gradually being replaced because of its inferior performance and backward technology.

On the other hand, in recent years, mankind has been paying more and more attention to environmental protection after realizing the danger of destroying the environment.

PVC is very harmful to human health and environment. It has also attracted the attention of international environmental organizations and people concerned about PVC.

Some ecologists and the international Greenpeace organization believe that the chlorine industry, especially the PVC industry, is the main source of dioxins in the environment.

Because PVC produces and releases toxic dioxins in the production process, toxic additives in PVC products can also pollute the environment, and enter the human body with certain carcinogenic effects.

The treatment of PVC waste is more difficult. Whether it is burning or burying, it produces and releases dioxin and chlorinated compounds that cause land and water pollution, and the recovery and utilization of PVC is very difficult.

The material provided by Greenpeace shows that the chemical additive phthalein, which can make PVC become softer, has great influence on human kidney, liver and testis. It can lead to cancer, kidney damage, damage to human body functional reconstruction system and influence development.

In recent years, experiments in some countries have shown that children are likely to inhale toxic chemicals from PVC toys.

Therefore, in recent years, green peace organizations, ecological organizations, greens or "green" politicians in some European countries and cities have constantly put pressure on the government, so that some governments have adopted the policy of restricting the use of PVC products, such as: Holland has banned the use of PVC for packaging, and Billy once collected "ecological tax" on PVC mineral water bottles.

In the past two years, the development of TPU (thermoplastic polyurethane) has also brought great impact to the development of PVC artificial leather. Compared with PVC, TPU is more popular because of its superior performance and environmental protection concept.

At present, wherever PVC is used, TPU can become a substitute.

But TPU has the advantages of PVC.

TPU not only has excellent characteristics of high tension, high tensile strength, toughness and aging resistance, breathable and moisture permeable, oil resistant.

It is also a mature environmental protection material.TPU has been widely used in shoes, clothing, inflatable toys, underwater and underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, suitcases, leather bags and so on.

A few days ago, the state's "promotion of industrial structure adjustment, Interim Provisions" and "industrial structure adjustment and guidance catalogue" were officially promulgated. The regulations and catalogues clearly defined the objectives, principles, directions and priorities of the current industrial restructuring.

In adjusting the division of directories, energy consumption and environmental protection have become an important criterion for the division of industries.

Among them, the guidance catalogue is divided into encouragement, restriction and elimination.

PVC ordinary artificial leather production line is being restricted.

The restrictive category mainly refers to products that are backward in technology, do not conform to the industry access conditions, and are not conducive to the upgrading and upgrading of the industrial structure.

For existing production capacity, enterprises are allowed to take measures to upgrade and upgrade within a certain period.

It can be seen that the development of PVC artificial leather products has come to a declining era. In today's environmental protection and health become the theme of human concern, the harm of PVC artificial leather to the environment will gradually be eliminated. Maybe in the near future, PVC artificial leather products will become a history, and our market will only leave healthy and environment-friendly products.

The development of synthetic leather industry must also be directed towards environmental protection in order to continue healthy development.
