Leather products are woven works of art. They come in a variety of colors, sizes and prices. Some leather products are quite hard, made from genuine hide. Others are made from cow hide that has been recreated through different types of tanning. There are leather products for children and adults.
The leather industry is an international trading industry that generates the finished, processed, and exported hides used to create leather goods. Animal skins are typically used to create the leather from which wallets, shoes, belts, dresses, bags, purses, coats and other leather goods are crafted. The hides generally are an unrivaled renewable source. The animal skins are typically harvested from animals such as deer, buffalo, elk, moose, seal and walrus. When treated well and humanely, the hides can be used as a valuable raw material. The animals utilized for leather products, whether harvested from the animals listed above or not, are a valuable resource used in the leather industry giay ca sau nam.
Today, the United States is the largest exporter of leather goods in the world. The U.S. accounts for approximately 25% of the world’s total leather production. The majority of American leather is produced by tanneries. Tanneries are businesses that specialize in the manufacturing of leather goods and in tanning and processing leather products.
When tanning hides, the natural color of the hide is maintained, but the leather is made darker. This process is called tanninning and leather tanned products have a higher price per leather product than do raw hides. The leather industry tans hides at different stages of their maturity. The more mature a hide is when it is sent to a tanner, the richer the leather will be when finished.
Tanning equipment includes tanning beds, water baths, and steam distillation machines. Water is required to raise the temperature of the water bath and keep the hides immersed and waiting to be tanned. Many of today’s modern tanning equipment processes involve automatic controls to control the temperature of the water, which results in fewer baths and less time consuming processing. This results in shorter turnaround times and more profits for the leather production facility.
The tanning process also depletes the hides of their pigments. Leather is a natural product that requires animal skin to be dyed. Animals are routinely fed hormones during the tanning process that speeds up the production of melanin – the dark pigment in the hide – and cause the color to darker. These synthetic pigments, commonly referred to as dyes, have a large environmental footprint and create a carbon footprint of their own.
