Haute Body believes everyone should implement a daily comprehensive UV protection strategy. This strategy should include the use of sunscreen, wearing UV-protective clothing, and limiting the amount of time you expose yourself to UV radiation. With this in mind, items made from HB-UV™ offer UPF50, found in the excellent protection category.

UPF Rating: 50|  Protection Category: Excellent  |  % UV radiation Blocked: 97.5 - 99+

1    UPF is the abbreviation for Ultraviolet Protection Factor (UPF). It is a rating system used for apparel. It indicates how effectively fabrics shield skin from ultraviolet (UV) rays. The higher the UPF number, the greater degree of UV protection a garment offers. UPF is similar to SPF (Sun Protection Factor), the rating system used for sunscreen products. UPF gauges a fabric's effectiveness against both ultraviolet A (UVA) and UVB light. An SPF number pertains only to a sunscreen's effectiveness against UVB rays, the sunburn-causing segment of the ultraviolet spectrum

2    Sunlight includes rays of invisible ultraviolet (UV) radiation; overexposure to UV rays can lead to sunburn, accelerated skin aging and skin cancer. Sunscreen and clothing offer your main forms of UV protection.

3    All fabrics disrupt UV radiation to some degree. Clothing that does the best job carries an Ultraviolet Protection Factor (UPF) rating from 15 (good) to 50+ (excellent).

About UPF

Q: How do I interpret UPF ratings?

A: AATCC 183 method defines the UPF rating for a fabric/textile as the ratio of UV measured without the protection of the fabric (compared to) with protection of the fabric. UPF measures both UV radiation transmittance using a laboratory instrument (spectroradiometer) and an artificial light source. These results are translated using a mathematical expression based upon the sunburn action spectrum (erythema action spectrum) integrated over the relevant UV spectrum. Theoretically, both human SPF testing and in vitro laboratory instrument testing measure a product's relative ability to protect against minimal sunburn compared to skin that is not protected. The higher the UPF number, the better the protection the fabric offers. All fabrics in some way impact the transmission of UV radiation.

You may read that fabrics "absorb" UV rays, but that wording implies that fabrics somehow soak up UV radiation like a sponge. That's not exactly the case. When ultraviolet radiation and textiles interact, the energy of UV rays is changed. UV radiation is converted to heat, a transformation that renders most rays harmless. Some garments, depending on factors such as construction, dyes and fabric treatments, do a better job at this than others. The original Australian rating system stipulates that garments made with fabrics rated below UPF 15 cannot be marketed as UV-protective

How Sun Protection Clothing Works

Q: What makes some fabrics more effective at disrupting UV rays than others?

A: There are a variety of factors:

  Construction: Dense, tight construction (either weaves or knits) minimizes the spaces between yarns, which in turn minimizes the amount of UV light that can pass through. Some tightly constructed UPF-rated garments use vents to boost air circulation and help the wearer stay cool. Thicker fabrics also help reduce UV transmission.

  Dyes: It is the specific type of dye (and the concentration in which it is used) that impacts a fabric's UV transmission, not its color. Some dyes deflect more UV radiation than others, and some absorb none at all—including black dyes. How can one know what kind of dyes are used in individual garments? The only tip-off is if the garment carries a UPF rating. Clothing engineered for UV protection may use high concentrations of premium dyes that disrupt UV light. Such dyes include "conjugated" molecules that disrupt UV radiation. The higher the concentration of such dyes, the darker the garment becomes. But ultimately color has no influence on UV rays. Note: Pigment-dyed fabrics, which include a resin that creates a powdery look and feel, get high marks for UV protection.

  Treatments: Chemicals effective at absorbing UV light may be added during processing. Specialized laundry additives, which include optical brightening agents and newly developed UV-disrupting compounds, can boost a garment's UPF rating.

  Fiber type: Polyester does an excellent job at disrupting UV light (due to hydrogen- and carbon-based benzene rings within the polymer). Nylon is good. Wool and silk are moderately effective. Cotton, rayon, flax and hemp fabrics (natural fibers composed of cellulose polymers) often score low without added treatments. However, unbleached or naturally colored cotton performs better at interacting with UV light than bleached cotton.

  Stretch: If a garment is stretched 10% or more beyond its normal dimensions, spaces between yarns are widened and its effectiveness against UV light may be reduced up to 40%.

  Wetness: A fabric's ability to disrupt UV radiation is usually reduced when wet, though the reasons why are not completely understood. Wetness may cause a 30% to 50% reduction in a fabric's UPF rating.

   Condition: Worn or faded fabrics are less effective against UV light.

Q: How does laundering affect UPF-rated clothing?

A: A study paper on the effects of repeated laundering of UPF-rated clothing was published in November 1998, in Textile Chemist and Colorist, an industry journal. The paper's conclusions assert that "repeated home launderings (regardless of whether or not the detergent contains an OBA [optical brightening agent, the compound commonly found in household detergents, mainly to "keep whites white"]) does not reduce the UPF rating of a woven or knitted fabric of cotton, polyester, or nylon. On the contrary UPF ratings are enhanced or remain unchanged by repeated launderings up to 20 times."
