UV Tests

Today, due to many factors, a large increase in the intensity of ultraviolet rays, which forms part of the sun's rays reaching the earth, is observed. In parallel, the need for protective textiles is increasing in order to protect people from harmful sun rays. The ultraviolet (infrared) transmittance of the fabrics produced in order to protect the skin and eye diseases of the workers working in the open area is directly related to the fiber type of the fabrics, yarn structure, surface texture, moisture content and finishing and finishing processes of the fabrics.

While textile products provide protection against ultraviolet radiation, the dose of radiation is also an important factor. Therefore, substances which will absorb infrared rays into textile products are applied during the production of more fibers or during finishing processes. By using ultraviolet absorbents in production, the permeability levels of infrared rays in textile products are reduced. Ultraviolet absorbents absorb the harmful rays that affect the fabric and eliminate the possible effects on human health.

Porosity in fabrics is a very important feature that determines the transmittance of infrared rays. For example, the woven and air permeable fabrics have a low infrared radiation permeability and a high protection factor. In the meantime, the higher the moisture content of the fabrics, the higher the infrared permeability. However, in the case of textile materials being moist or dry, their infrared transmittance differs from each other. Viscose fibers have high dehumidification capabilities. The fabric that provides the best protection against ultraviolet rays is wool woven from natural fibers. Wool, silk, linen and cotton fabrics follow. Polyester fibers provide the highest protection in synthetic fibers.

During the specific test studies, the current regulations and the relevant standards published by many domestic and foreign organizations are taken into consideration. In line with the needs of the enterprises, our organization also performs UV tests within the framework of specific tests.

Meanwhile, our organization has been accredited by ÖSAS accreditation organization in accordance with TS EN ISO / IEC 17025 General Requirements for the Qualification of Testing and Calibration Laboratories and serves within this framework.
