A cloth structure includes a first weaving layer, a second weaving layer interwoven with the first weaving layer, an intermediate connecting layer located between the first weaving layer and the second weaving layer, and a sun protection layer applied on the first weaving layer. The cloth structure presents a single-cloth fabric. The sun protection layer covers pores of the first weaving layer and forms a first protection layer to filter the smog. The first weaving layer is formed with inverted V-shaped cloth patterns, so that the first weaving layer forms a second protection layer to filter the smog. The intermediate connecting layer forms a third protection layer to filter the smog. The second weaving layer obstructs the thread openings of the first weaving layer and forms a fourth protection layer to filter the smog.
