Chrome tanned leather is probably the
most common tanning method. It means that chromium is used in the
tanning process, as opposed to the vegetable tanning process where a
variety of organic substances are used. Chrome tanned cowhide leather includes a wide variety of leathers.
First of all, tanning is the process
of obtaining leather from animal skin. It is a process that involves
changing the structure of the hide in order to make it more durable.
Hides are processed in a tannery. If this process wasn’t done, the hide,
as an organic material, would slowly rot.
The vegetable tanning process
or veg tan is the oldest method of tanning. It involved soaking hides
into tanning solutions. The process can be time-consuming; it is usually
done by hand and requires patience and skills.
It takes around two months to finish
the whole process. But, because the tanning solutions are natural, it
doesn’t have a negative environmental impact.
Vegetable-tanned leather is usually
stiff and comes in its natural color. If colored, colors tend to darken
over time. Since the procedure is significantly longer, the products are
usually more expensive.
The complexity, expense and time involved with tanning with vegetable tannins led, in 1858, to the development of using mineral tanning agents
instead. The basic principle is the same, removing water molecules from
the collagen and replacing them, but the process is much quicker using chrome
which is the most popular mineral tanning agent today. The whole
process can be automated and finished in a day, and the chrome ions
displacing the water and binding with the collagen are much smaller than
vegetable tanning molecules. This generally makes chrome tanned leather thinner and softer than vegetable tanned leather.
Although chrome tanned leathers
and veg-tanned leathers are different, the beginning of the tanning
process is similar and the goal is to remove water molecules from the
collagen. The process, however,
is less natural than when using vegetable tannins. It involves first
placing the hides in acidic salts to better make the chrome fit in
between the collagen molecules – and then returning the hides to a
normal pH level.
Chrome tanning quickly became popular
because the whole process was much quicker and it produced softer
leather. Chrome tanned leather can also be dyed so it’s a great option
for different customers.
Chrome tanned leather includes common
upholstery leather you might find on a couch, chair or in your car
covering your seats. Chrome tanned leather also includes handbags and
the leather used to make them. Usually chrome tanned leather is very
soft and pliable, but it can also be stiffer. Either way, chrome tanned
leather is available in a wide variety of textures and colors. Chrome
tanned leather has a uniform coloring and will not patina as much over
time likevegetable tanned leather.
Chrome tanned leather is also more resistant to water, heat and stains than vegetable tanned leather. Chrome tanned cowhide leather can be pebble grained, smooth or have various embossed patterns and prints.
