Backing/Cushioning (B/C) materials are an important component of artificial leather, providing structural support and comfort to the final product. There are several materials that can be used as B/C, including polyester, nylon, non-woven fabrics, and cotton. Each type of backing cloth has its own unique properties and characteristics, which can make it more or less suitable for different applications.

Polyester

Polyester is a synthetic fiber that is made from polyethylene terephthalate (PET), a polymer that is derived from petroleum. It is lightweight, durable, and easy to clean, making it a popular choice for a wide range of artificial leather products. Polyester also has good dimensional stability, meaning it maintains its shape even under stress, which is important for a B/C material. However, it is not as breathable as some other materials and may not provide as much comfort as other options.

Nylon

Nylon is another synthetic material that is commonly used as a B/C in artificial leather. It is strong, durable, and resistant to abrasion, moisture, and chemicals. Nylon provides excellent strength and durability, making it a popular choice for high-performance artificial leather products. However, it can be more expensive than polyester and may not be as soft or breathable as other materials.

Cotton

Cotton is a natural fiber that can also be used as a B/C in artificial leather. It is soft, breathable, and absorbent, making it a popular choice for low-performance artificial leather products where comfort and breathability are more important than durability and resistance to wear and tear. However, cotton is not as durable as synthetic materials and may be more prone to damage from moisture, abrasion, and chemicals.

Non-woven fabrics

Non-woven fabrics, such as spunbond, meltblown, and spunlace, are made by bonding fibers together without weaving. These materials are often used as a B/C in artificial leather because of their good breathability and softness. Non-woven fabrics are also less prone to fraying and tearing than woven materials, which can be important in a B/C that is subjected to wear and tear. However, they may not be as durable or as moisture-resistant as synthetic materials like polyester or nylon.

In conclusion, the choice of B/C material for artificial leather depends on the specific requirements of the product, such as durability, comfort, breathability, and cost. Polyester, nylon, non-woven fabrics, and cotton are all viable options, each with its own strengths and weaknesses, and the best choice will depend on the specific requirements of the application.
