What is UV protection fabric?
Ultraviolet Protection Factor (UPF) indicates how much UV radiation (both UVB and UVA) a fabric allows to reach your skin. For example, a UPF 50 fabric blocks 98 percent of the sun’s rays and allows two percent (1/50th) to penetrate, thus reducing your exposure risk significantly.
What is the difference between SPF and UV protection?
SPF stands for “Sun Protection Factor”. It measures the amount of time it takes for sun-exposed skin to redden, while UPF measures the amount of UV radiation that penetrates a fabric and reaches the skin. Remember that SPF only accounts for UVB rays unless specifically stated as a broad-spectrum sunscreen.
How do you make fabric UV protected?
Tightly woven fabrics The second way to make a fabric UPF 50+ is to make sure the fabric is tightly woven. The tighter the weave, the more UV protection a garment is, as holes in between the fibers allow sunlight to get through unimpeded.
How does UV protective clothing work?
With UV protection clothing, more of the sun’s rays are blocked, and you get more sun protection. For example, a shirt with UPF 50 only allows 1/50th of the sun’s harmful UV rays to get through to your skin. This means it blocks 98 percent of the sun’s radiation before it reaches your skin.
What color blocks the most UV rays?
Darker colors absorb more UV than lighter colors like whites and pastels. This means the UV rays are less likely to reach your skin. But bright colors such as red can also absorb UV rays. The more vivid the color, the greater the protection—a bright yellow shirt is more protective than a pale one.
