Makkah Madina Leather Complex(MMLC) started 2001 by Md. Kamrul Huda (Razib). We do All Kinds of Finished, Crust & Split Leather & Chemical Import.
Crust Leather:
Crust leather is the term applied to leather, which is dried after tanning but has not yet been dyed. In the case of chrome- tanned leather, this is known as “chrome crust” and, for vegetable-tanned leather, as “vegetable crust”.
Finished Leather:
The purpose of leather finishing is to embellish the leather, to give it a specific colour and shine. It helps to protect the leather. The finishing of leather affects the look, the feel and the strength of the leather. We distinguish 3 leather finishes: aniline, semi-aniline and pigmented.
Split Leather:
If a skin is divided into several layers over the entire surface, this process is called “splitting”. Thicker leather, mostly cow leather, which is 5 to 10 millimetres thick, is split. The obtained layers are designated as grain split or top-grain split and flesh split.
Leather chemicals:
Leather chemicals include chemicals used for tanning, dyeing and retanning across various stages of leather production
process. The leather processing industry depends upon the changing scenario in the fashion industry.
Chemicals Used in Leather Processing
Biocides. Biocides prevent the growth of bacteria which can damage the hides or skins during the soaking process.
Surfactants. …
Degreasers. …
Swell regulating agents. …
Lime. …
Sodium sulphide. …
Sodium hydrosulphide. …
Low sulphide unhairing agents.
Leather Factory/Tannery:
Tanning is the process of treating skins and hides of animals to produce leather. A tannery is the place where the skins are processed. Tanning hide into leather involves a process which permanently alters the protein structure of skin, making it more durable and less susceptible to decomposition and coloring.
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.
