As heatstroke alert announcements have become almost routine, Japan's summers are getting hotter every year.
Among various countermeasures for the sweltering heat, more people are carrying parasols than before. Not only adult women, but also men and elementary school students can now be seen commuting with parasols.
How do parasols function to block heat and light? The focus here is on "
SUMMER SHIELD®" from "
TORAY INDUSTRIES INC." which boasts a high light blocking and UV cut rate of over 99% and can lower the perceived temperature by up to 4 degrees.
We spoke with Tatsuhito Kanda, the Section Manager of the Apparel Materials Section of the Sports & Textile Materials Business Department at Toray, to uncover the secrets behind this.
