The preparatory stages are when the hide/skin is prepared for tanning. During the preparatory stages many of the unwanted raw skin components are removed. Many options for pretreatment of the skin exist. Not all of the options may be performed. Preparatory stages may include:
Preservation- the hide/skin is treated with a method which renders it temporarily unputrescible.
Soaking – water for purposes of washing or rehydration is reintroduced.
Liming – unwanted proteins and “opening up” is achieved.
Unhairing – the majority of hair is removed.
Fleshing – subcutaneous material is removed.
Splitting – the hide/skin is cut into two or more horizontal layers.
Reliming – the hide/skin is further treated to achieve more “opening up” or more protein removal.
Deliming – liming and unhairing chemicals are removed from the pelt.
Bating – proteolytic proteins are introduced to the skin to remove further proteins and to assist with softening of the pelt.
Degreasing – natural fats/oils are stripped or as much as is possible from the hide/skin.
Frizzing – physical removal of the fat layer inside the skin. Also similar to Slicking.
Bleaching – chemical modification of dark pigments to yield a lighter colored pelt.
Pickling – lowering of the pH value to the acidic region. Must be done in the presence of salts. Pickling is normally done to help with the penetration of certain tanning agents, e.g., chromium (and other metals), aldehydic and some polymeric tanning agents
Depickling – raising of the pH out of the acidic region to assist with penetration of certain tanning agents
- Raw material indent:
Raw material required for manufacturing the products are estimated by the production manager. Then the required materials are arranged by the purchase manager. This data is uploaded in this module. In order to track the consumption details for the product manufactured raw material indent is must.
The leather manufacturing process is divided into three sub-processes: preparatory stages, tanning and crusting. All true leathers will undergo these sub-processes. A further sub-process, surface coating may be added into the sequence. The list of operations that leathers undergo vary with the type of leather.
Understanding the requirements of patrons, we are engaged in best quality Raw / Wet Blue Leather Imports. We import the leather from the most trusted vendors of the industry. Further, we make these leather undergo a treatment process under the supervision of expert professionals. Prior to dispatch, we check these leather so as to ensure their flawlessness.
Our imports include: Miss-happen skins, under sized, Sheep skins, Goat skins, and Cow hides
These imports are available in Raw, Pickle, Wet blue, Vegetable tanned and Crust leathers
- Chemical Requirement
Leather chemical includes chemicals sodium nitrite, sodium nitrate, leather dyes, disinfectant, tannery cleaning chemicals, solvents, wax, silicone emulsion. The amount of chemicals required for manufacturing are estimated and submitted using this module.
- Dyeing chemical process
A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution, and requires a mordant to improve the fastness of the dye on the fiber. Both dyes and pigments appear to be colored because they absorb some wavelengths of light more than others. In contrast with a dye, a pigment generally is insoluble, and has no affinity for the substrate. Some dyes can be precipitated with an inert salt to produce a lake pigment, and based on the salt used they could be aluminum lake, calcium lake or barium lake pigments.
Archaeological evidence shows that, particularly in India and Phoenicia, dyeing has been widely carried out for over 5,000 years. The dyes were obtained from animal, vegetable or mineral origin, with none to very little processing. By far the greatest source of dyes has been from the plant kingdom, notably roots, berries, bark, leaves and wood, but only a few have ever been used on a commercial scale. Here dyeing process is carried out for finished leather manufacturing.

Impregnation systems (aqueous and solvent borne) for fill and to strengthen the crust
Fillers (water and solvent based) to improve uniformity, adjust gloss, give oil and wax pull up effect, as well to adjust the feel.
Auxiliaries to optimize the performance of the finishing systems such as foaming, water repellence, spotting resistance, finish penetration and special effects.
Finishes ready for use or only require addition of water.
Modifiers (water and solvent based) offer improved surface handling, special tactile fashion effect and improve the physical performance of the leather.
Deller’s added to a basecoat and/or topcoat adjust the gloss, feel and appearance of the leather and give special fashion effects.
Topcoats (aqueous and solvent based) to meet the required fashion effects and specific physical performance requirements by the most demanding markets. Our topcoats can impart a specific colour, shade, cover and minimize defects and give metal effects.
Pigments (aqueous and solvent based) either containing protein for shoe upper leathers or protein free for soft nappas and garment leathers as well as for upholstery.
Dyes (metal-complex) to shade undyed crust, increase anility and create fashion effects.

- Leather order entry
Consists of Leather purchase order entry. This module provides the complete details about the purchase order given by the customers. This will be used as a master form in order to avoid the repetition of entries this master form will be used.
- Finishing machinery operation
Once a hide finishes the tanning process, the leather can be manipulated for a variety of looks and textures. At the tannery the leather undergoes a series of wet operations for coloring and oiling. After the hide dries and it is in the “naked state”, it can be mechanically conditioned for different look or feel. Some of these same techniques can be used at your work bench. Beyond dying and oiling the leather, we’ll take a look at physical conditioning methods to give plain old leather a new and different look.
The different finishing machinery operations are staking, buffing, boarding, plating (embossing), glazing, brushing,
- IN / OUT for Jobwork process
Usually the entire factory setup will not able to in the same campus itself. Leather is a durable and flexible material created by the tanning of animal rawhide and skin, often cattle hide. It can be produced through manufacturing processes ranging from cottage industry to heavy industry. Because due to pollution problem raw state to wet blue state of leather will be done in the nonresidential area. For this case the leather is shifted to one factory to another one for various operations. This operations are updated in this module for tallying the stock. Usually leather will be referred by lot number with number of hides & sides.
