Crusting process starts the time when the hide is thinned, retanned and regreased. Often a dye method is included in the crusting. Also, part of the crusting process includes drying and softening.

 

Crusting may include the following process depending on the type of leather: Below is the detailed process of making crust leather.

Splitting:

Splitting is a process where thicker leather is sliced into two layers.The layer without a grain surface can be turned into suede. It also has an artificial grain surface applied. A splitting machine slices the leather according to the thickness you set on it.

Neutralisation:

 The pH of the leather is included.

Retanning:

Additional tanning imparts properties.

Dying:

The dyeing of leather into a wide variety of colors plays an important part in meeting fashion requirements. Some leathers are the only surface dyed, while others need completely penetrated dyeings, in related with suede leathers.

Fixation:

Unbound chemicals are chemically bonded or removed from the leather.

 

Fatliquoring and Stuffing:

Fats, oils, and waxes are added between the fibers to soften the leather. Without these oils, the leather will become hard and inflexible as it dries out.

Shaving:

A machine cuts leather fibers from the flesh side. A uniform thickness is achieved by shaving the leather on the non-grain side using a machine with a helical blade mounted on a rotating cylinder.

 

Wetting and Conditioning:

Leather has to be rehydrated in the following steps.

Sammying: Water is squeezed out the leather.

Drying: The leather is dried to different moisture levels.

Filling:  Some dense chemicals are added to make the leather heavier and harder.

Stripping: Superficially fixed tannins are removed from leather by stripping.

Softening:  The leather is softened by the tumbling action inside a rotating drum. Physical softening of the leather by tumbling and stacking.

SPLIT SUEDE CRUST LEATHER 

Suede leather is the name of two kinds of leather. One is the part leather (twofold sided velour surface. The second is the uncoated tissue side of a smooth cowhide. As opposed to the extremely smooth nubuck, cowhide is altogether rougher.

 

The most widely recognized utilization of suede leather is on tennis shoes and work gloves. In the two cases, the defensive capacity and the solid breathability of this sort of calfskin are fundamental. Softened cowhide is exceptionally permeable, and sweat can, along these lines, go through effortlessly. As hands and feet sweat rapidly, this is a critical favorable position.

 

Tennis shoes regularly have surfaces made of suede leather. With goatskin shoes, the velour side (tissue side) is handled outwardly.

 

Suede leather is regularly utilized for working gloves.

 

 

While sticking leather on two parts, the substance side cowhide strands are regularly squeezed and stuck down heretofore with the goal that abnormalities are not obvious on the upper side later.
