I. Definition of Leather:
Rawhide, the unprocessed skin directly removed from an animal, is the raw material for making leather. Leather is the skin after undergoing a series of processing steps.
II. Types of Leather:
Leather comes from a wide range of animals, including cows, pigs, sheep, snakes, horses, kangaroos, crocodiles, and lizards. Among these, cowhide, pigskin, and sheepskin account for as much as 95% and are the main raw materials in the leather market.
III. Anatomical Structure of Genuine Leather:
The structure of leather is quite complex; it is actually composed of four different layers. These layers not only differ in function but also affect the texture and durability of the leather to some extent. Understanding these layers is important for a deeper understanding of the properties and applications of leather.
Composition of Leather and the Function of Each Layer:
Leather is composed of multiple layers, each with a unique function that affects the overall properties of the leather. The following is a detailed description of the main components and functions of each layer of leather:
Grain Layer: This is the outermost layer of leather, mainly composed of protein fibers, with a fine texture and gloss. It gives leather its unique texture and aesthetic appeal.
Reticular Layer: Located beneath the grain layer, it is formed by tightly interwoven fiber bundles, creating a network structure. This layer provides the leather with strength and toughness, making it durable and resistant to damage.
Tissue Layer: This is the main support layer of leather, composed of protein fibers and fat. It provides the leather with elasticity and softness, and also contributes to the leather's warmth and breathability.
Muscle Layer: Located innermost, it is mainly composed of muscle fibers and fat. This layer provides the leather with sufficient elasticity to adapt to different usage needs.
In addition, leather also contains a certain amount of minerals and other substances, which play an indispensable role in the stability and durability of the leather.
