Al-Madina Tannery(AMT) started 1988 by Haji Noor Mohammad Chowdhury. We do Producer & Exporter of All Kinds of Leather & Leather Goods. Bangladesh leather industry is well established and ranked second in terms of export earnings. Because of its high value addition, huge growth and employment opportunities, leather sector has already been declared a top priority sector.
Al-Madina Tannery use Syntan in leather product that is used as retanning material for chrome tanned leather. Leathers treated with acrylic syntan have fullness, tightness of grain, good buffing characteristics and improved dye intensity. The technology is available at lab scale level.
We also use Fatliquoring of leather chemicals that process of introducing oil into a skin following tannage but before the leather is dried. In fatliquoring, which is usually applied to light leathers, the oil is introduced into the leather in such a manner that the individual fibers of the skin are uniformly coated.
“Fatliquor” is the most widely used wet chemical applied in the form of an emulsion at the end process of leather tanning. It keeps the leather soft, smooth, light, and heat fasting by preventing the fibrils from the aggregation and filling the voids.
CETP-based Savar tannery estate management:
The age-old tannery cluster of Hazaribagh has been shifted to a newly build up environment friendly tannery estate at Savar. The new tannery estate with its new concept has been continuing its production process and productivity since its discontinuation of Hazaribagh on April, 2017. The Common Effluent Treatment Plant (CETP) is the main component of the industrial basement at Savar Tannery Estate. The management of a CETP of this kind at its post commissioning stages involves (a) technical management and (b) financial management.
Environmental Compliances:
Authorities are also responsible as Savar tannery estate lacks key environmental compliances. Around a decade ago, there were two choices before the local leather industry: adopt the best environmental practices in tanning and get good prices in the global market, or skip the nature concern and be underpaid with the major foreign markets inaccessible.
Foreign buyers, especially big brands, want to see LWG certification for sourcing leather and leather products from the international market. To get the certificate, factories must ensure they are not hurting the environment while manufacturing the products.
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 Goods:
Currently, the entire leather industry is divided into different sub-sectors, one of which is ‘Tanning & Finishing’. In this sector, several tanneries are producing crust leather, finished leather, and blue wet leather. According to LFMEAB, there are currently 200 tanneries and 3500 MSMEs in Bangladesh.
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.
