A roll blind according to the present invention has a three-dimensional curtain sheet (2) formed by quadruple or sextuple integral weaving and including: a base net sheet (10); multiple shade sheets (12) transversely extended, and longitudinally arranged on the base net sheet (10); and longitudinal opening and closing yarns (14) separated left and right, and arranged on the shade sheets (12), wherein each of the shade sheets (12) has an upper extended part (16) integrally woven to the base net sheet (10) by warps and a lower extended part (18) integrally woven to the longitudinal opening and closing yarns (14) by warps. The base net sheet (10) and the shade sheets (12) are sequentially woven, wherein each of the shade sheets (12) formed from a twilled or a satin triple woven layer has: an upper layer (12a) and a lower layer (12c) forming the front and the rear side of the shade sheet (12) when opaque yarns (20) inserted into wefts are exposed; and an intermediate layer (12b) capable of creating indoor darkness when forming a blackout by black yarns inserted into the wefts. Therefore, according to the present invention, the curtain sheet is capable of not only controlling the shading and the transmission of a light, but also blocking incident light using the blackout, thereby creating the indoor darkness without the installation of an extra blackout curtain. |
