Synthetic leather意思

"Synthetic leather" is a term used to describe various types of materials that are designed to resemble natural leather, but are made from synthetic compounds. These materials are often used as a more affordable or sustainable alternative to genuine leather, and they are commonly found in a wide range of products, including clothing, footwear, furniture, and automotive upholstery.

Synthetic leathers are typically made from a base of polyurethane (PU) or polyvinyl chloride (PVC), which are then treated with dyes and finishes to give them the look and feel of real leather. PU leather, also known as "bicast leather" or "split leather," is made by coating a split leather (the bottom layer of the hide) or a synthetic substrate with a layer of polyurethane. This process can result in a material that is more flexible and breathable than PVC leather, but it may not be as durable.

PVC leather, on the other hand, is made by coating a fabric backing with a layer of polyvinyl chloride, which is then embossed to give it the texture of real leather. This type of synthetic leather is often more durable and resistant to water, but it can be less breathable and may not age as well as PU leather.

Synthetic leathers have a number of advantages over genuine leather, including lower cost, the ability to be produced in a wider range of colors and textures, and the fact that they do not require the use of animal hides. However, they also have some disadvantages, such as a shorter lifespan and the potential to contain harmful chemicals.
