HOME STAKING MACHINE TANNING HIDES SKIN

The PH of the raw cowhide after liming is higher, which is not conducive to tanning and therefore requires de-liming. It can also be done using hand tools and scraping/scudding.Īt this point, the cowhide is well cleaned and prepared, and what is left is the most quality parts, which will be further refined and turned into leather during the tanning process. This is the final step in the Beamhouse phase. This is usually done mechanically by machines, rollers, and blades. They have been weakened by the liming process, and unhairing can begin. Once limed, the cowhide is now ready for removal of undesired parts. This is more commonly referred to as a pelt.

Once the hair has been removed, we are left with raw cow skin. Mainly, these include the epidermis, roots of the hair, and additional undesired fats and soluble protein. These will not be needed later in the processing, or desirable in the final product. The liming step is to help remove a lot of the organic substances that might still be part of the cowhide. Washing is usually done in very large vats or rotating drums, with high volume of leather for efficiency. This allows for pliability and further treatment during tanning. The purpose of soaking is to clean the dirt and make the raw cowhide water back to soft.

HOME STAKING MACHINE TANNING HIDES SKIN

Raw cowhide will be stained with mud, blood, preservatives and other dirt, and after salting treatment, the water in the skin is lost seriously.

These preservation methods often involve sun drying, salting, freezing, chilling, or the use of chemicals. Therefore, it need to be cured or preserved. After removed from an animal, it can very quickly begin to degrade and decompose within only about 5 hours due to bacterial growth. This phase focuses primarily on taking the raw cowhide (cowhide that was just removed from a cow), and preparing it for the tanning process. Phase 1 Pre-tanning Step 1 Curingīeamhouse is the term that refers to the first phase in the cow leather tanning process. This process can be divided into pre-tanning, tanning and finishing according to the process. Compared with raw cow leather, processed leather is softer, more resistant to microorganisms, and has characteristics of chemical resistance, stronger flexural strength, and better air permeability.Ĭow leather processing is the process of chemical treatment and physical and mechanical treatment of raw cow skin to make it into leather. The peeled raw cowhide needs to be salted to prevent rotting before being sent to a leather factory for processing. Raw cowhide is a by-product of meat processing and is the raw material for making cow leather. Raw cowhide is the body surface tissue peeled off from a cow body, without any chemical or physical mechanical treatment. Though it is a product of the food industry related to cattle, it is also very often processed into leather. Cowhide is the natural and unbleached skin and hair of a cow. General Steps of Cowhide Leather Makingīefore going any further you should know cowhide leather meaning. Let’s explore a little background, then each of the making steps. The process of making leather dates back to ancient civilizations and has evolved into a streamlined process. Artsome cow leather is the first layer of cow skin imported from Italian tannery with the thickness between 1mm to 1.3mm, and we have a specialized leather coloring workshop, where we specialize in the making of antique cowhide leathers, which are used for making vintage leather sofas and chairs. Leather is not susceptible to bacteria and decay because of the altering of the protein structure in the skin. With leather so common, it is fascinating how many different techniques go into leather production and the tanning process. Leather can come in different colors, textures and finishes. Leather is made from the skin of animals and the skin through a tanning process. Tanning can take anywhere from a few days to a few months depending on the process used. Most people have owned something made out of leather and have at some point been curious about how leather is made. Leather is a very popular material that has been produced for thousands of years.
