How Leather Is Made What You Need To Know

How leather is made If you know where leather comes from, you may be able to grasp better what you’re receiving when you buy it. Animal skins may be tanned to create leather-like materials through drying and curing. When we need to utilize the whole cow’s skin, we shave the leather down to the desired thickness.

Cows specifically bred for their skin are currently the primary source of leather in the world. Leather from calves at least 26 years old is best since it’s supple and devoid of noticeable scars, making it ideal for clothing.

Leather, on the other hand, comes from sheep and goats. Numerous species produce enough hairless skins to avoid thickness problems in manufacturing, but many do not. There are two options: shaving before tanning or shaving it off afterward.

This article will cover more details on leather and its journey from animal to shop.

An essential part of a system

Leather may be made from various animals, although cows are by far the most common source.

There is a hefty price to be paid for rearing animals for leather. When beginning a dairy herd, there are a number of costs that may be prohibitive. May reduce these expenses by developing calves that can handle a wide variety of weather conditions.

The best leather came from cattle fed a diet of grass and permitted to wander freely. They must not be taken away from their mothers too early if they grow up healthily. Their therapy must be careful, as well. Depending on how the animal is cared for, the quality of the leather may be significantly affected.

Calves must be moved to a more fertile environment after weaning from their mothers. The cows’ long-term health depends on it, even if it seems to be cruel. Pregnant cows may not get adequate protein from grazing on pasture alone. Soybeans or milk substitutes are needed to guarantee that calves get appropriate nourishment while making leather.

. May achieve up to 80 percent yield by purchasing cows that have been well-cared for.

Exfoliating and removing the outer layer of skin

If you’re feeling a little nauseous, you may want to skip this part. Because leather is created from animal skin, there’s no escape from the reality that it must be removed from the cow to be utilized. Should use only a humane method of killing for cattle.

The first step in removing the cow’s hide is to make an incision around its neck. A sharp knife is next used to remove the remaining hair and tissue from the coat. Afterward, the blade is dragged backward, forming an extended length of leather.

The hide is then cleaned with salt and water. In the next 30 days, the clothing is hung. During the drying process known as ‘Curing,’ moisture is removed from the material.

When the curing process is complete, Beamhouse’s operations begin. Remove any excess meat and salt that did not absorb during the previous tanning procedure. “

To remove any salt residue, the leather is first immersed in freshwater. Hair and keratinous particles are then removed by liming.

To prepare the leather for “bathing,” a process known as “Deliming” is used to reduce the PH of collagen, which softens the material.

Curing hides with salt and acid is similar to pickling. As the animal’s hair is removed, it retains its shape. The skins are then soaked in water for some time.

After removing the hides from the water bath, a salt and oak gall brine solution is used to eliminate any remaining hair. This method also dries and smooths its surface when it comes to leather.

During these two weeks, the collagen in the leather is allowed to firm up and form natural fibers.

Tannination begins with these long and labor-intensive processes.

Tanning the skin

Tannic acid, a tannin found in the bark or leaves of many plants, is utilized in various tanning processes. May preserve hides by using tannin as a preservative in tanning. Tannery employees may pick from a wide variety of options based on personal tastes, time restrictions, and what is available in their area.

However, the process of tanning leather had significantly advanced since agave or mimosa plants were used to extract tannins from the leather.

Three of the most prevalent tanning methods include chrome, vegetable, and chrome-free tanning.

In this part, we’ll talk about chrome tanning.

Today, chrome tanning is the most used form of tanning. Chromium chloride or Chrome Sulfate is utilized in the preservation process. Fast turnaround and leather preservation are two of the benefits of this method. Many people like chrome-tanned skins to be rough and smooth, even though they may cause chafing or damage in rare cases. Commercial chrome tanning contains carcinogenic pollutants, such as chromium salts.

It’s time to get your hands on some vegetable tanning.

Vegetable tanning is the oldest method of tanning, and it is still widely used today. Unlike chrome-tanned leather, vegetable-tanned leather is softer and more supple, making it an excellent choice for upholstery. Vegetable tannins include chestnut, mimosa bark (Acacia), myrobalan (Terminalia chebula), and gambier (Quararibea funebris). Although it might be challenging to find these tannins, they are readily available.

Leatherworkers choose vegetable-tanned leathers for their smoothness and elasticity. It is also easier to clean and maintain since these leathers are more breathable. Sulfur is often added to vegetable tannins to create a more durable leather.

Chrome’s Free Tanning 3.3.

Chrome-Free Tannination Method is the new trend in leather tanning. Plant tannins are utilized in this method instead of chromium salts, making it safer and less detrimental to the environment. This technology does not pollute the environment and produces fewer carcinogens. Due to its efficiency, leatherworkers may prepare their hides more quickly using this procedure instead of chrome tanning.

Cowhides and goatskins are the most often used leathers in the shoe business. Pig and horse leathers tend to be more costly, but they are also more difficult to work with. Both are strong enough and supple for delicate handwork (e.g., carving).

Tanned again (Prefinishing)

A smoother, more uniform surface and longer lifespan are achieved by pre-finishing leather. The inherent markings of the leather may or may not be erased by chemicals, waxes, and other treatments before the leather is ready to be used.

After processing, the tannins in the skin must be returned to the leather to prevent drying and cracking. There is an effective barrier to UV light because of the tanning chemicals generated by plants. This promotes drying and cracking. It takes longer to tan leather because of a buildup of pre-tanning chemicals that interferes with the chemical interaction between tannins (which hardens the leather).

Various techniques, such as rolling, waxing, lubricating, injecting oil, or breaking or perforating, may be utilized in the retention process. You can also use coating, embossing, or coloring.

There is a Mill

Certain leathers will be tough following the Prefinishing procedure. Milling is now being utilized. May transform one material into another through milling. For example, a mill (a rolling pin) may be used to ground the sugar, and chocolate can be used as a flavor in chocolate-flavored butterscotch.

Finished vegetable-tanned leathers are generally too difficult for the majority of individuals. Mineral deposits from dirt or salt residue are to blame for this hardness. These materials are crushed into very fine pieces that “break down” mineral deposits to return the skin/hide to its original state.


An estimated $99 billion is spent annually on leather goods worldwide by 260,000 persons in the UK alone. Dedicated floor space will rise by 10 million square feet by 2021, resulting in annual growth of 11,043 new jobs.

Creating a single piece of leather requires a lot of time and energy.

There are many methods for creating skins, some of which have been described here, but there are undoubtedly many more. As a result, the next time you sit down to make a new bag, you’ll have a better idea of how much effort it takes to bring leather from the cow to your workstation.

The best of luck to you all!
