The UPF value of silk fabric increased with irradiation time at the beginning of sunlight-induced process and changed slightly after irradiated for 2 h (Fig. 7b), indicating that the reasonable irradiation time is 2 h for obtaining the optimal UV-blocking property of silk fabrics.
The well-maintained trail, with mossy rocks and tree limbs lining its edges, traces the river on and off near the beginning of the trek, sunlight filtering down through fanning branches of birches and oaks.
Soon, shafts of sunlight began to illuminate the white peaks above the tree line.
