Guys, the summer is coming, the beaches are getting crowded and the clothes with UVA and UVB protection are ensuring the protection of children and adults.
Sun protection clothes may seem new, but the fotoproteção mecânicarealizada through barriers like clothing and hats – is the oldest form, common and easy to protect from ultraviolet radiation (UVR). Today, however, the effects of the Sun are far more worrisome than years ago, when people were not aware of all the harm provided by radiation emitted by the star.
“In addition, the outdoor sports, such as street racing, won many adherents in recent years, with all the more reason to protect themselves from exposure to the Sun’s rays with the use of clothes with protection”.
Of Australian origin, manufacturing of smart fabrics that block UV rays was developed in 1996, as a method to reduce the high incidence of melanoma-skin cancer type-in the country, whose inhabitants are, in most of your light skin and suffer from the intense solar radiation.
The ARPANSA (Australian Agency for Radiation protection and Nuclear Safety) is responsible for creating the standard that quantifies the level of protection offered by the clothes — that is, the percentage of UV filtered by a fabric. “Clothes with UPF 15 and 20 block of 93.3% 95.9% of the ultraviolet radiation, offering good protection,” explains Daniela Palharine, Coordinator of professional products of national Textile Cedar mill.
And continues: “Clothes with UPF 20, 30 and 35 block of 96% to 97.4% of the radiation. That is, provide very good protection. And clothes with UPF 40, 45 and 50 block more than 97.5% of UVR. Therefore, allow for excellent protection. Pieces with indexes below 93.3% are not considered to be fotoprotetoras. ”
Note: Second recommendation Dermatology, the use of the parts does not dispense the application of sunscreen in the regions that are discovered.
Didn’t take long for the concept win the world and other countries create their own regulations, taking into account the incidence of radiation of each region. As in Brazil there is a specific technical standard, textile companies have adopted the Australian solar protection parameters.
Consequently, the fabrics used are subjected to rigorous tests performed by laboratories accredited by Inmetro, which follow the standards of the ARPANSA, in order to check the efficiency of the FPU. Hence the importance of certification for consumer safety. “Items such as t-shirts, caps, visors, gloves, swimsuits and items for the practice of physical activities and recreation receive certificates and reports attesting to your protective capacity”
How are made?
There are two processes that ensure the FPU in the products: while the synthetic fabrics made of polyester and polyamide fibers, for example, are made from yarn based on titanium dioxide, the cotton gets a photo protector additive that is incorporated into the process of improvement, after dyeing, to supplement the passage of harmful rays. “This is an aqueous chemical bath which strengthens protection levels of a fabric, following the Australian standards. A common fabric of department stores have FPU until 5. With the processing, it passes to achieve the highest levels of protection, providing UPF 50, for example ”
As well as the sunscreen threads, fabrics with UV Protection technology are made to reflect UVA and UVB. That way, when exposed to the Sun, the clothes will not allow the skin to absorb the radiation. According to manufacturers, the shielding effect begins immediately to put them on, not requiring a waiting time before sun exposure, and continues as long as you remain dressed.
The protective function has long-acting and is directly linked to the care with the piece. “It’s always indicated wash them without the use of chemical bleaches, dry shade and don’t keep them wet to avoid wear of the fabric”, recommends Ana Julia Pellegrino, managing partner of UV. LINE, company that sells items with this appeal.
Also according to the brand Director, Lyonel Pellegrino, the protection is permanent and can’t commit to washes that follow the recommendations contained in the tags. “The protection lasts as long as the product is solid and will only be committed if the laundry is damaged.” Among the warning signs are threadbare, punctures, tears and abrasions that make the thinnest tissue, indicating that the shield is not 100%.
So, children and adults can use and abuse of clothing with sunscreen.
All you need to know about Ultraviolet Radiation
Ultraviolet radiation (UV) is about 7% of the total radiation emitted by the sun and is divided into 3 sub-ranges: UVA, UVB and UVC. Each wavelength has a different effect on humans.
As the time and intensity of exposure, the effects range from the synthesis of vitamin D3 to the precocious and skin cancer. More dressing fashion in NONPROFITdictionary.
