The main testing standards for UV-resistant textiles in the United States are as follows:
(1) ASTM D6544 Standard Practice for Preparation of Textiles Prior to Ultraviolet (UV) Transmission Testing, "Standard Practice for Preparation of Textiles Prior to Ultraviolet (UV) Transmission Testing";
(2) AATCC 183 Transmittance or Blocking of Erythemally Weighted Ultraviolet Radiation through Fabrics, "Performance Testing of Textiles for Transmission or Blocking of Erythemally Weighted Ultraviolet Radiation";
(3) ASTM D6603 Standard Guide for Labeling of UV-Protective Textiles, "Guide for Labeling of UV-Protective Textiles".
There are mainly two standards for UV-resistant textiles in the European Union:
(1) EN13758.1-2006 Textiles - Solar UV Protective Properties - Part 1: Test Method for Apparel Fabrics
(2) EN13758.2-2003 Textiles - Solar UV Protective Properties - Part 2: Classification and Marking of Apparel。
The UV resistance of textiles is a significant issue in the textile industry. There are many factors that affect the UV resistance of textiles, including fiber type, dyes, yarn density, material thickness, light wavelength and UV intensity. At the same time, the formulation of testing methods and standards also plays a crucial role in ensuring the accuracy and scientific nature of the UV resistance of textiles.
There are various factors that affect the UV resistance of textiles.
Fiber type: Natural fibers (such as cotton, linen, silk, and wool) have a certain degree of UV resistance, while synthetic fibers (such as polyester, nylon, and polypropylene) have relatively poor UV resistance. Dye: The UV absorbers added during the dyeing process significantly influence the UV resistance of textiles. Certain dyes containing UV absorbers can effectively enhance the UV resistance. Yarn density: The higher the yarn density, the stronger the UV resistance of the textile. Material thickness: The thicker the material, the stronger the UV resistance. Wavelength and intensity of light: Different wavelengths of UV light cause varying degrees of damage to textiles. UVB wavelengths (290-320nm) cause more damage to textiles, so tests usually use UV light within this range.
