Quality Control


Leather is a non-homogenous material, which makes its quality check a complex exercise. Depending upon the end use of leather, it is tested through a wide spectrum of tests for evaluating conformance to quality over various parameters. These include visual, chemical and physical tests.

The most important parameter in leather quality is the fibre structure. Basic physical tests conducted are for tensile property, elongation, rub fastness, flexing, stitch tear and tongue tear strength. Other quality control measures include flexing test, grain crack/distension, colour fastness, shrinkage test, water vapour permeability and water absorption. Chemical testing helps evaluate the presence of essential chemicals in leather in light of eco-sensitivity as well as their quality enhancing properties. The lab has equipment like UV-visible spectrophotometer, GC and HPLC, which function in temperature and humidity controlled environments. Boil test is done to ascertain the tanning quality of leather. Patch test is done by taking small swatch and dyeing it. PH control is maintained throughout the process in addition to temperature control. The dyed material after ageing is taken to Setting Section and the material is inspected lot wise check for proper setting. After setting operation, material is taken to vacuum operations and vacuum operation is done at a particular temperature and timing is also maintained. Thereafter material is sent for conveyor drying and finally passed through drying chamber keeping check on temperature and humidity. General tests are conducted that include free Formaldehyde testing (Gas Chromatography), CR-VI, PCP and AZO to ensure that the leather is free of all toxicities and chemicals do not exceed permissible limits. The material is then visually examined through sampling by a team of five senior quality control personnel.



Shoes and other leather products exceed the customer requirements and match globe-wide standards of quality. This quality is ensured through stringent quality processes at all stages of production. Drish uses only home produced leather from its own tanneries. The leather is visually examined through sampling techniques to ensure conformance with the sample approved for production. The manufacturing process begins with leather component cutting. Cutting is done as per samples provided by the sample development team. Cut components are then checked and passed by QC team for production. Quality is assured at all other stages including showboard designing, upper making, counter moulding, lasting, midline passing, sole bonding, lacing, brushing and packaging. Other material like threads, rivets, eyelets and other embellishments are also tested for strength, colour fastness, etc.



Leather is a natural material, and we use chemicals for tanning within the prescribed limits. Therefore, it is highly unlikely that wearing our leather shoes (leather upper and leather lining) will cause an allergic reaction. Synthetic materials, on the other hand, are made of several chemicals and are more likely to cause allergic reactions. We do not use synthetic/faux leather in any of our products.
