Testing & Quality

Sunole products are tested in Turktex laboratories to ensure reliable performance in outdoor environments. Testing procedures evaluate the effects of UV radiation, humidity and weather conditions on textile materials. Through continuous research and development, Turktex ensures that Sunole yarns and fabrics meet the required standards for durability and long-term performance.

4.1 Test Methods

ISO EN 105 B04 - Colour Fastness to Artificial Weathering

This test evaluates the light fastness of dyed textile products during production and usage. It helps determine the resistance of textile materials to fading when exposed to artificial light sources simulating sunlight.

ASTM G154 - Accelerated Weathering Test

This test simulates outdoor weather conditions such as sunlight, moisture and temperature variations. The accelerated weathering device allows long-term outdoor exposure to be evaluated within shorter testing periods. Through this method, Turktex analyzes potential material changes and improves product performance during the research and development process.

Real-life Weathering Tests

Sunole fabrics are tested in multiple locations under real outdoor conditions. Throughout the testing period, fabrics are exposed to natural sunlight, humidity and environmental effects. These tests are conducted over several years to evaluate long-term durability and color performance. All observations and test results are carefully recorded and analyzed to support continuous product improvement.

4.3 Quality Control

All production processes are continuously monitored to ensure consistent quality. Through systematic inspections and data monitoring, potential issues are detected at an early stage. If a quality-related issue occurs, corrective actions are taken immediately. Even after delivery, Turktex stands behind Sunole products, ensuring reliability and customer satisfaction.

* Upon request, finished customer products can also be tested in Turktex laboratories.
