When it comes to protecting the skin from dangerous solar radiation or UV radiation in spring and summer, most people use creams with UV protection. The problem here is that even sunblock, the strongest cosmetic sun protection product, only offers a sun protection factor (SPF) of 50. This also gets washed off when you are in the water or rubbed off when you are drying yourself, and must be re-applied several times to ensure long-term protection.
Textiles with UV protection are much more practical. Depending on the specification, these can achieve a UV protection factor (Ultraviolet Protection Factor; UPF) of up to UPF 80. This means that the wearer can stay protected in the sun for up to 80 times longer than the self-protection time that is dependent on the wearer’s skin type.
However, because the UV protection factor is neither visible nor tangible, we conduct neutral tests and certifications for you based on international standards and then offer you the opportunity to claim the determined UPF in the form of our Hohenstein label on the item of clothing.
At Hohenstein, we test and certify the UV protection of textiles according to different standards. These include, amongst others, the Australian/New Zealand Standard (AS/NZS 4399) and the European Standard (DIN EN 13758-1) and, in rare cases, the American Standard (AATCC TM 183), which allows advertising with the Hohenstein Quality Label.
To give your customer reliable information about the UPF of your textiles, we recommend that you have the protection factor of your products tested and certified according to the UV STANDARD 801. This is because it is the only standard in the test that includes the particular requirements that your sunscreen textiles are subjected to when used. This means that your textiles are tested under the most realistic conditions, for example, in wet, stressed and used states (after wear and washing).
In addition to consumer safety, our test of the UV protection factor also offers you the opportunity to optimise your products during development. You also benefit from fewer complaints due to the neutral tested quality and you can use the material certificate for optimum marketing of your products.
Skin is not only damaged by natural solar radiation. Care is also required with artificial UV radiation. In order to be able to specify the UV protection factor of protective clothing for welders, for example, we calculate the UV transmission accordingly for personal protective equipment which can then be used to determine the maximum usage duration of the textiles in the respective welding process.
