HOW ITALIAN LEATHER IS MADE

 

STAGE 1: Liming

  • Hides are preserved by salting after slaughter.
  • Natural dirt is removed by washing with water.
  • The original water content is restored to 65%.
  • During the liming process fats and other unnecessary natural substances are removed.
  • The high pH value during this process loosens and dissolves the hair chemically.

 

STAGE 2: Splitting

A moving blade is used to split the leather horizontally (like a sandwich) creating 2 layers:

  • The top grain /the outer part where there the hair was
  • The split / the inner part.

Note that the fibers in the top grain are much more compact than the ones in the split.

The top grain is therefore softer, much more resistant to tearing and as a result more expensive.

 

STAGE 3: Tanning

  • Tanning preserves leather over time avoiding decomposition.
  • Tanning can be done using different tanning agents, the most common of which is chromium that produces a bluish color, hence the name ‘wet blue’ given to tanned leather.
  • Especially, Italian leathers are respected worldwide for its traditional vegetable tanning process, making leather more friendly to environment and customer (vegetable tanning leather are all used for making our high-end product lines)

STAGE 4: Dyeing

  • Dyeing involves immersing the leather in penetrating dyes which color all its surfaces and sections.
  • Then the ‘wet blue’ dye becomes “crust”.

 

STAGE 5: Selection

  • Leather is selected based on the presence of different natural characteristics and intended use.
    • Aniline
    • Semi Aniline
    • Pull Up (Waxed)
    • Suede (Nubuck)
    • Pigmented
    • Bycast

 

STAGE 6: Stucco application

(only for pigmented leather)

  • Leather often has a number of natural markings which require removal to ensure they are desirable to customers.

  • This is done by filling or covering them with a white paste called ‘stucco’  before removing the top part of the grain.

  • The upper part of the top grain is then removed using abrasive paper to smooth the surface removing most of the natural markings.

FULL GRAIN LEATHER is UNbuffed and therefore more valuable than BUFFED leather which has been filled and sanded.

STAGE 7: Finishing

(only for pigmented leather)

  1. Color the basecoat with pigments to cover all defects and to create a uniform finish.
  2. Emboss with a hot plate or a roller to achieve the desired texture and hide any further visible natural markings.
  3. Apply a transparent top coat to block any transfer of color, protect the leather and confer the feel and opacity desired.

TYPES OF LEATHER

italian leather italian productions company

ANILINE (also known as ‘Natural’)

The surface of this leather is dyed with transparent dyes.

This effect of transparency is similar to the one observed by looking at a piece of colored wood, where the color does not cover, but enhances, the nodes and natural grain of the wood. In fact, the top grain remains natural and very visible. The aniline leather will then have some imperfections that naturally occur ensuring that each piece is unique. Leather of this type has only minimal coverage on its surface, so it is more sensitive to the effects of wear.

To maintain its natural beauty it is absolutely necessary to follow a a cleaning and protection routine from the beginning of its use.

Advantages:

  • Natural appearance
  • Excellent feel
  • Natural, top grain and minor defects
  • Very soft and breathable

Other features:

  • Visibility of natural defects
  • Variations in color
  • Expensive
  • Hard to keep clean
  • Poor resistance to light
  • Unevenness of grain

SEMI-ANILINE

This type of leather is covered by a slightly pigmented finishing, to make the color more uniform and hide small defects.To preserve the natural look of the leather, they are then sprayed with bright, transparent colors.
Advantages:

  • Natural grain finish
  • Pleasant feel and appearance
  • Improved lightfastness compared to pure aniline leather
  • More practical than aniline leather
  • Breathable

Disadvantages:

  • Visibility of major natural defects
  • Slight variations in color
  • Needs maintenance

PIGMENTED

This is the most widely used finishing technique consisting of a uniform surface of a basecoat of pigments and resins followed by a protective topcoat. They can be identified by their consistent color and uniformity. This type of leather is ideal for frequently used items like furniture and automotive seats especially when a ‘child friendly’ solution is required. Full refinishing is possible whenever restoration is necessary.
Advantages:

  • Uniform color and covering
  • Good coverage of defects
  • Light-resistant
  • Economical
  • Easy to maintain

Disadvantages:

  • Looks less natural than aniline leather

NUBUCK

Nubuck is actually aniline leather that has a sanded surface to give a fine, velvety surface. The look and feel of this leather are incomparable and work well for infrequent use.
Advantages:

  • Velvety appearance and touch
  • Very soft, warm and natural
  • Soft and breathable

Disadvantages:

  • Expensive
  • Sensitive to stains which are difficult to remove

PULL UP (Wax &/o oil)

Fashions come and go, but waxy, oiled leather is here to stay!
'Pull up' was originally used to describe the effect on a type of leather known as “Timberland” after the well-known footwear producer made this type of article famous. This leather lightens when stretched, folded or “pulled up”.
Advantages:

  • Great look and feel
  • Vintage effect
  • Unique streaked lightening effect when pulled or folded

Disadvantages:

  • Requires regular maintenance

BYCAST

This leather type requires a completely different system of finishing or enhancing ‘split’ or ‘heavily buffed’ leather which maintains uniform thickness and softness. The technique consists of creating a finishing film on a continual support of release paper. An adhesive is applied to the film, then the film is pressed onto the leather. The finished leather is then removed from the release paper displaying a perfectly uniform surface.
When bycast leather is stretched, a lighter color is visible which disappears once it is not pulled.
Advantages:

  • More resistant than ‘split’ / ‘heavily buffed’ leather
  • Economical

Disadvantages:

  • An unnatural look and feel
  • Requires protection from skin oils

 

 


 

QUALITY / PRICE OF LEATHER

Why is there such a difference in price between different types of leather? Price depends on the amount of natural marks visible on the leather at the time of slaughter. Hides totally free of natural markings are rare and therefore very expensive.

Natural markings

These are found very frequently in animals and are caused by:

  • Insect bites
  • Tarola (insect lava)
  • Open scars
  • Healed scars
  • Blind grain
  • Wrinkles
  • Branding iron scars
