SANAS SECRET ?
Highest Quality Standards We Set
"For Ourselves & For Our Competitors".
Kiran spent significant amount of time understanding the Leather Tanning process to be sure he his objectively picking the best Leather for his project.
SANAS brand is very proud that they use Highest Grade, Vegetable Tanned, Full Grain, Italian Cow Leather. We believe it is critical for every leather consumer to be aware of leather facts to make informed decisions based on the value of the leather they are investing in.
We not only want to save people from being scammed but also want to educate. Depending on the leather you are investing in, a $500 investment on one Leather Product could be more valuable / durable over the time than a $5000 dollar leather product you may invest on because of a perceived value of a brand name like Louis Vuitton , only to realize that the leather they used is actually lower in quality.
Our intent is not to point finger to another brand but o educate consumers , so that you can understand "Exactly Why SANAS MARVEL Leather is Higher Quality than LOUIS VUITTON Leather Quality". We do not claim the Legendary LOUIS VUITTON with a 100 years of history does not have the heritage brand value. After disappointedly owning their products We respectfully disagree on the quality of the leather they use.
To Understand Leather Quality You need to understand Two Aspects of Leather Making Process - Tanning and Splitting.
Why Leather Tanning ?
Animal skin is made of a substance called collagen, which is skin’s main structural protein. Stabilization of these proteins is necessary in order to prevent the skin from breaking down and naturally decomposing. To prevent this from happening humans have, since the Stone Age, made use of tannins and their antioxidant capabilities, to make the skin resistant to the protein cleavage by enzymes (rotting) and thus conserving the leather.
Tannins are “a yellowish or brownish bitter-tasting organic substance present in some galls, barks, and other plant tissues, consisting of derivatives of gallic acid, used in leather production.” And the process of using tannins to preserve collagen is called tanning.
What are the Two Major Types of Tanning ?
There are various tanning methods being used today. The oldest and most intricate process is vegetable tanning.
Newer, faster tanning methods make use of minerals like chromium sulfate (i.e. chrome tanning, chromexcel), which wasn’t invented until the mid-nineteenth century.
Vegetable tanning is the traditional method of tanning leather, its method dating back to approximately 5000 BCE. Like the name suggests, veg-tanning is an organic method relying on natural vegetable tannins from bark or other plant tissues. Tannins from trees such as oak, chestnut, or mimosa are popular, but hundreds of tree types and other plants are known to have been used.
Vegetable tanning is generally a time-consuming process requiring highly skilled craftsmen, which involves soaking hides in large baths of concentrated tannins over a course of several months. This method is the most typically associated with luxury goods, and has a very Natural feel and “earthy” smell , Feels more organic/‘alive’.
It’s basically the same principle: to cross-link the collagen matrix to prevent putrefaction and hence decomposition. This is done by binding chrome salts to the collagen protein, forming cross-links between the two, thus creating stable structures of chromium-protein complexes. The method utilizes large rotating drums with chromium salt solutions “washing” the leather.
Chrome tanning is significantly faster than vegetable tanning and can be done in less than a day, and it generally produces a supple leather that keeps its finish but does not keep its form throughout its “life”. Life of Chrome tanned leather is significantly less than that of the vegetable tanned leather.The method of chrome tanning is responsible for about 80% of all leather production worldwide due to its properties and product efficiency, making it a low-cost way of preparing leather. The use of heavy metal minerals, however, is often more damaging to the environment.
Why Vegetable Tanned Leather is Superior Than Chrome Tanned Leather ?
Environmental Impacts of Chrome Tanning
The environmental impacts of leather manufacturing can be measured by two key parameters:
- How the leather is manufactured: from hide to finished leather
- What inputs are used to manufacture it: chemical selection
These two parameters roughly determine how eco-friendly the leather manufacturing process is. The biggest downside to chrome tanning is purely the chemical used in this tanning process and the second major downside is the scale at which it’s practiced. Because of the fact that Tanning process takes significant amount of water which is now mixed with Chromium when released into the environment has as destructive impact as that of a drug manufacturing company releasing all their waste into the environment. Chrome has end-of-life issues too which are greater than other tannages like tree bark used in vegetable tanning.
What is the Leather Splitting Process ?
The Unsplit cow hide is too thick to work with or to make any leather products. So it needs to be split horizontally to make it thin enough so that it is just the perfect flexibility for the specific purpose the split is done.
Hide would have the outer surface called grain side which tough enough to withstand the tough impacts of various objects for the entire life of the animal , Now the important aspect of Splitting is once you horizontally split the hide, you took that tough part of the hide away which is called the Grain Split.
Grain Split is toughest part of the hide, It is the most costliest part of the hide. It is the only part of the hide that meets SANAS standards.
The second half of the hide without the Grain part of it is called Flesh Split. As this would have the flesh on the bottom side and some Corium fibers on the top side.
What are the Leather LAYERS ?
WHAT IS FULL GRAIN LEATHER GRADE ?
If the Outer surface of the Grain split from the Leather splitting image above is not altered in any way and the finished leather intact with FULL GRAIN from the original animal skin, then it is essentially called FULL Grain Leather. This also means the leather has the full strength of the skin which can withstand a lifetime of rough impact.
The grain also has breathability, resulting in less moisture from prolonged contact. Natural markings on the skin such as scratches or stretch marks are visible, but are not excessive or unsightly and in fact, are considered the "signature of fine leather." Some people are surprised to learn that the absence of natural markings can often mean a lesser quality tanned leather hide. But excessive markings will also mean it is lower class leather, so there is fine line between the best and the rest of the leathers.
Only 10-15% of all hides will qualify for the best class A and can be finished as Full Grain Leather. Full Grain Leather also refers to hides that have not been sanded, buffed, or snuffed as opposed to any grain correction to remove imperfections on the surface of the hide.
Most companies don't dare to use Full Grain leather because of two major issues.
1. It is super expensive.
2. It cannot be mass produced because of the limited availability.
WHAT IS TOP GRAIN LEATHER GRADE ?
The term 'Top grain' leather is widely misused.
There is a very wide range of leathers that fall under the 'top grain' umbrella.
Typically Top Grain Leather means , it is made from top portion of the hide but is is missing the outer most Grain layer because it has been "corrected" through sanding away natural markings and major blemishes on the leather’s surface. Once the surface is uniform, it is typically embossed into a natural grain skin pattern or pebble grain pattern, to give it an illusion of Full grain leather. As You can imagine this won't last long - let alone a generation.
The best way to really understand top grain leather is to compare it to full grain leather.
Top grain leather is like a new car's paint job. It looks its best on day 1, and gradually over time, as it gets nicked and scratched, the top grain leather product looks gradually worse over time. Top grain leather products do not form patinas, nor does the leather heal itself.
Typical designer handbags from name brands like LOUIS VUITTON are made using top grain leather.
BUT NOT SANAS BAGS.
WHAT IS GENUINE LEATHER GRADE ?
The most misguided , brilliantly named and worst quality leather is Genuine leather - only useful to deceive the general public.
This is the softest and weakest , left over, lower half of the leather including some of the dried flesh.
They press the top of this leather with artificial grain pattern to give it an illusion of leather and to prevent the leather from falling apart temporarily.
So next Time You read Genuine Leather as Weakest Leather.
WHAT IS BONDED LEATHER GRADE ?
Bonded leather is as the name implies, is leather scraps, leather dust, vinyl, glue and plastic, all bonded together.
RUN FROM IT.
What are Leather classes ?
Leather class is determined based on how many markings are on the leather. Obviously every animal which has lived longer than a day bump into something as part of its daily life and by the it is harvested it has markings from its life.
The reason the Italian leather has the most value is because the Best Italian Farms take great care while raising these animals to prevent as many markings as possible and Best Italian Tanneries will only make Full Grain Leather from CLASS A skins, which have rare markings and outside of main parts of the hide from where the leather products are made.
