However, there are gaps in scientifi c knowledge about exactly how colour interacts with other factors to infl uence a fabric’s ability to block ultraviolet protection factor (UPF).

但是，关于颜色到底是怎样与其他因素作用来影响布料紫外线防护系数（UPF）的科学知识还存在一些缺口。

The result is a material that is not only waterproof but is able to block out UV radiation from the sun to such an extent that it would rate a Ultraviolet Protection Factor (UPF) of 101.15 if the chart went that high.
