Umbrella UV protection indicators
Date：2023-12-17
The UV protection index of an umbrella is usually related to the material and processing method of the umbrella cloth. Here are some common indicators related to UV protection:
UPF (Ultraviolet Protection Factor): UPF is a measure of the protection of textiles (including umbrella fabrics) from UV rays. Similar to the SPF on sunscreen, the higher the UPF, the stronger the umbrella cloth is at blocking UV rays. Usually, UPF ranges from 15 to 50+, with higher values indicating better protection.
Ultraviolet transmittance: This refers to the proportion of ultraviolet rays that the umbrella cloth is allowed to transmit. The lower the transmittance, the stronger the protective effect of the umbrella cloth. Some umbrellas will clearly state their UV transmittance, usually expressed as a percentage.
Material selection: Some special umbrella cloth materials, such as silver-plated nylon or materials coated with UV absorbers, can effectively protect against UV rays. Check the umbrella's material description to see if it has UV protection.
Production process: Some UV-resistant umbrellas undergo special processing during the production process, such as adding UV absorbers or using UV protection technology to improve the protective effect of the umbrella cloth.
When choosing a UV-resistant umbrella, you can check the product description or label to learn about its UPF rating and other relevant information. High-quality UV-resistant umbrellas are usually clearly labeled with their protective properties and use advanced technology to improve protection.
