What Type of Raw Hides are Used to Make Leather

When it comes to the world of leather, the variety and quality of products are as diverse as the raw materials used to create them. From the sturdy boots that protect our feet to the luxurious handbags that carry our essentials, leather is a versatile material that has been cherished for its durability and aesthetic appeal for centuries. In this blog post, we’ll delve into the types of raw hides used to make leather and the intricate processes involved in transforming these hides into the leather products we know and love.

The Raw Materials (Raw hides)

As mentioned earlier, the primary raw material in leather production is animal hide. However, the type of animal and the specific part of the hide used can greatly influence the characteristics of the final product. Here’s a more detailed look at some of the most commonly used hides in the leather industry:

Cowhide:

This is the most widely used hide due to its size, thickness, and durability. Cowhide can be split into two layers: the outer layer (top grain) and the inner layer (split grain). Top grain is the highest quality and most durable part of the hide, making it ideal for high-end leather goods and furniture. Split grain, on the other hand, is more affordable and is often used for suede or corrected grain leather.

Sheepskin:

Known for its softness and lightweight nature, sheepskin is often used for clothing, gloves, and bookbinding. A unique characteristic of sheepskin is its wool, which can be left intact and used for products like shearling coats or rugs.

Goatskin:

Goatskin is tougher and more durable than sheepskin, yet it remains supple and flexible. It’s often used for bookbinding, gloves, and high-quality leather goods. Its distinctive pebbled texture is a result of the animal’s hair follicles, which are visible on the surface of the leather.

Pigskin:

Pigskin is less durable than cowhide but is more breathable, making it a popular choice for shoe linings and gloves. It has a unique texture characterized by small, dotted patterns.

Exotic Leathers:

Apart from these common types, there are also exotic leathers sourced from animals like alligators, snakes, and ostriches. These leathers are highly prized for their unique textures and patterns, but they’re also more expensive due to the rarity of the hides and the complexity of the tanning process.

It’s important to note that the quality of the raw hide can be influenced by various factors, including the animal’s diet, age, and living conditions. For example, hides from animals that have been free to roam tend to be stronger and more durable than those from animals kept in confined spaces.

Here’s a comparison table of the different raw materials used in leather production:

Please note that the common uses listed in the table are not exhaustive, and the same type of leather can be used for various other products depending on its treatment and finish.

The Tanning Process (Raw hides)

Once the raw hides are cleaned and prepared, they undergo a process called tanning, which stabilizes the proteins in the hide to prevent it from decomposing and makes it resistant to water and wear. There are several tanning methods, each with its own benefits and drawbacks.

Vegetable Tanning

It is the oldest and most traditional method of tanning. It uses natural tannins found in plant matter such as tree bark and leaves. This method produces a strong, rigid leather with a distinctive natural color that deepens over time. It’s often used for belts, saddles, and other items that require a sturdy material. You can learn more about this process in our blog post about vegetable tanning.

Chrome Tanning

It is a more modern method that uses chromium salts. It’s a faster process that produces a softer, more flexible leather that can be dyed in a wide range of colors. Chrome-tanned leather is commonly used for clothing, handbags, and footwear. For more details about this process, check out our post on the chrome tanning process.

Synthetic Tanning

It uses synthetic chemicals and is typically more affordable than vegetable or chrome tanning. However, it doesn’t last as long or look as good as natural leathers. It’s often used for small accessories like wallets and purses.

Mechanical Operations in Leather Processing

After tanning, the leather undergoes several mechanical operations to achieve the desired thickness, texture, and finish. These operations include fleshing, sammying, splitting, shaving, setting, and drying, among others. Each operation plays a crucial role in transforming the tanned hide into a finished leather product.

The Final Product

The end result of these intricate processes is a piece of leather that is ready to be crafted into a wide range of products. From the sturdy leather boots by Timberland to the luxurious handbags by Prada, the possibilities are endless. Each product reflects the unique characteristics of the raw hide it was made from and the specific tanning method and mechanical operations it underwent.

Conclusion

The world of leather is a fascinating one, filled with a rich history and a wide variety of products. Whether you’re a fashion enthusiast, a leather craftsman, or simply someone who appreciates the beauty and durability of leather, understanding the types of raw hides used to make leather and the processes involved in its creation can deepen your appreciation for this timeless material.

Remember, when you purchase a leather product, you’re not just buying an item, but a piece of art that reflects centuries of tradition, craftsmanship, and innovation. Each leather product tells a story – from the life of the animal where the hide originated, through the hands of the craftsmen who transformed it, to the individual who eventually owns and cherishes it.

In a world increasingly dominated by synthetic materials, leather stands out for its natural beauty, durability, and sustainability. It’s a material that ages with grace, acquiring a patina over time that only adds to its appeal.
