Sustainable production

Thanks to today’s developed and accessible technology, leather tanning now respects and looks after the environment.

Systems for managing and recovering natural resources and the waste produced were implemented in all the production cycle phases, counting also on a methodology that protects the working environment and the health of the workers.
According to Dani, sustainability does not just mean satisfying the legal limits set by the industry; it also means continuing to look for innovative solutions that favour the environment, the people who work for the company and future generations.

This is possible thanks to Dani’s collaborations with the whole district, which includes local chemical product companies, those who run the purification services, and all the companies involved in recovering tannery waste.
The product is transformed completely in this area, which means that our leather embodies the true spirit of Made in Italy (Leather from Italy Full Cycle).

Production cycle

“The quality of the finished product is the result of many variables in the production cycle, which only consolidated experience in the tannery world can guarantee.”

Beamhouse – Preparation for tanning

During the ‘riviera’ phase, all the processes that prepare the leather for tanning are carried out: desalting, soaking, unhairing, liming in drums, mechanical scudding, trimming and splitting.

1.
Preliminary operations
the raw hides are cleaned and the subcutaneous fat recovered
2.
Chemical preparatory operations
• soaking • unhairing • liming
3.
Mechanical preparatory operations
• fleshing • trimming • splitting

Tanning and retanning

Treating the leather in a drum with tanning agents followed by embossing, splitting and shaving. The tanned leather is called “wet blue” or, if tanned without using chrome, “wet white”.
The retanning, dyeing and fatliquoring processes follow, which add colour, consistency and softness to the leather.

4.
Tanning
• deliming • bating • pickling and tanning
5.
Mechanical preparatory operations
• samming • splitting • shaving
6.
Dyeing
• retanning • dying • fatliquoring

Drying and finishing

The sammying operation eliminates the excess water.

Other drying operations follow (combined according to the characteristics of the article): vacuum drying, air drying and toggle drying. The dried leather is called “leather in crust”.

Various operations that make the leather soft and shiny alternate during the finishing phase: pigment spraying, protective resin spraying, wax spraying and staking.

The finished leathers are selected one by one, measured, and then destined for different markets, from furnishing to footwear, clothing to leatherware.

Drying
• sammying • vacuum drying
• air drying and toggle drying
8.
Refinishing
• buffing • milling • spraying • pressing/ironing

Final quality check

Before sending the leather to our clients, its organoleptic qualities are checked for the last time and it is tested in a laboratory, as agreed on previously with clients.

9.
Selection and sizing
The irregularities in each piece of leather are located and identified on the basis of a fault catalogues supplied by each client.
10.
Laboratory
The Dani analysis laboratories, equipped with cutting-edge equipment and specialist technical staff, close the production cycle. They guarantee quality and performance through:

  • systematic checks on the performance requirements of each lot during all the production process phases
  • written reports that give the results of the tests carried out
  • specific tests for the product destination sectors according to European and international standards
  • daily checks on the incoming chemical product requirements
  • research on process innovation, coming from the interaction of and collaboration with the department technicians
