In the Kasar Dual testing laboratory, all strength and physical tests are conducted for each production batch. Fabrics are tested using devices under standard physical testing conditions: 65% ±4 humidity and 20°C ±2 temperature.

Washing fastness, Water fastness, Sweat fastness, Friction fastness, Phenolic yellowing, Size change after washing, Twisting after washing, Pilling test (ICI Pilling Test, Martindale Pilling Test), pH, Weight, Width, Tensile strength, Tear strength, Recovery elasticity

The chemical laboratory consists of three main units: knitting fabric dyeing, pad-batch dyeing, and chemical analysis.

Formulas are created using an automated dosing machine under the computer guidance of specialized colorists. The total number of colors produced daily is 700–750. Pre-conditioning measurements of the fabrics are conducted with a Datacolor spectrophotometer. Tests for formaldehyde, pH, etc., are carried out for each batch in accordance with Malaoeko-tex 100 standards.

The results of the tests conducted are considered a valuable resource for diagnosing and correcting potential errors in production processes. This approach not only allows for managing the process in which production decisions are based on a more solid foundation but also greatly contributes to increasing customer satisfaction by consistently delivering products that meet quality standards.

Although the Yarn Physics Laboratory makes an important contribution to the production of superior quality yarns, we continuously pursue our activities by staying updated on the latest technological developments in the industry and strictly adhering to international standards. In this way, we maintain our goal of leading the sector by maximizing customer satisfaction.
