UPF stands for Ultraviolet Protection Factor. Synthetic fibers like polyester and nylon offer greater protection than natural fibers. The weave and color of the fabric are also important. A tightly woven, dark-colored denim weave is better than loosely woven white linen.

What type of fabric is UPF?
What does UPF mean? The UPF stands for Ultraviolet Protection Factor which is a numerical rating to clothing. This rating shows how UV radiations will be blocked by the UPF fabric. A UPF protection clothing with rate 50 means that only 2% (1/50th) of the Ultraviolet rays can penetrate the UV blocking fabrics.
Do all fabrics have UPF?
Yes, your clothing shields you from the sun, but not all fabrics and colors provide equal protection. Luckily, you have plenty of options.
What is the most UV resistant fabric?
Solution-dyed polyester is especially great for outdoor use – it has exceptional UV/sun resistance and wear properties.
Can cotton be UPF?
“Most cotton shirts give you an equivalent of about a UPF of 5 when you’re wearing it,” Dr. Vij explains. “Most fabrics that we wear are a loose weave that lets visible light peek through and get to our skin.
How can you tell if fabric is UPF?
Generally speaking, if a fabric has been tested to determine it’s UPF rating you will see it somewhere on the fabric itself. It may be fused onto the inside of the shirt, or on the tag. In addition, you can also quickly look it up online to see if the UPF rating is listed in the description.
Are all polyester shirts UPF?
Polyester and wool fabrics usually provide sufficient UV protection (UPF 30+), while other fabrics, such as cotton, linen, and viscose, frequently offer poor UV protection.
What fabric is best for sun protection?
Fabrics that are better at blocking the sun include:
- polyester.
- nylon.
- wool.
- silk.
Do normal clothes have UPF?
A normal t-shirt typically has a UPF rating of 5, which means that 1/5th (roughly 20%) of UV radiation permeates its fabric and reaches your skin. In contrast, sun protective clothing with a UPF rating of 50+ means that a maximum of 2% of all UV radiation reaches your skin.
Do normal clothes block UV rays?
Be aware that covering up doesn’t block out all UV rays. If you can see light through a fabric, UV rays can get through, too. Many companies now make clothing that’s lightweight, comfortable, and protects against UV rays even when wet.
Which color is best for UV protection?
Dark or bright colors
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.
What kind of fabric won’t fade in the sun?
If you are planning on placing items in a sunny location, consider natural fabrics like cotton, wool, and wool blends. Fabrics blended with acrylic, polyester, and nylon are also less likely to fade.
Does polyester protect from UV rays?
Type of Material: Synthetic fabrics like nylon and polyester do a good job of blocking UV. Bleached cotton is a poor barrier material. Fabric Treatments: Chemicals that absorb or disrupt UV radiation can be added by the manufacturer.
What materials can block UV rays?
Nylon and polyester are the next best options, and thicker fabrics such as tweed and denim are also suitable. Linen and bleached cotton will offer less UV protection, but any shirt is always better than no shirt!
Does UPF wash out of clothing?
Depending on the durability of your clothing, the fabric composition may be compromised after only a couple washes. In other words, as the threads thin out, the shirt allows more UV light to pass through. So while the UPF does not necessarily “wash out,” the UV protection rating will eventually drop over time.
Are jeans UPF?
Denim jeans can have a UPF value of 1700 (Geis 2012). The reason: tighter weaves, dark or bright colors and thicker fabrics block more UV rays. If the fabric is wet, stretched out or too tight, it will block fewer UV rays.
Do you wear sunscreen under UPF clothing?
Do I need a sunscreen with my UPF clothes? Since UPF clothing protects from 98% of the sun’s rays, there is no reason to put sunscreen underneath the UV clothing. If you prefer to apply sunscreen underneath, we recommend to apply it 15 minutes before you wear your UV protective clothing to prevent staining.
What is the UPF of a cotton shirt?
A typical white cotton T-shirt, for example, offers about a UPF 5 rating, which means that 1/5th (roughly 20%) of available UV radiation passes through it.
Can you get sunburn through linen?
On the other end of the spectrum, linen does not provide much sun protection due to the nature of the fabric. The weave is much looser, and the overall weight of the fabric means that there is not much blockage from the sun.
Does canvas block UV rays?
The results show that canvas has a very high capacity for absorbing radiation, “with only 5% transmissivity,” but this does not prevent diffused ultraviolet radiation from penetrating through on the sides.
Is UPF better than SPF?
SPF is better known than UPF
For example, SPF 15 blocks 14/15th or 93% of UV radiation. Whereas, SPF 50+ blocks at least 49/50th of UV radiation. As an aside, it is important to buy a “broad spectrum” sunscreen as this will block both UVA and UVB wavelength rays.
