Description of the Invention: [Technical Field] The present invention relates to a fabric for curtains, and more particularly to a fabric for curtains which is suitable for making a variety of curtains and for shielding light. [Prior Art] Generally, curtains are designed with different structures and types depending on the needs of use. Common types of curtains are: folding curtains, blinds, roller blinds, Roman blinds, etc., with different curtains. The material used to block light also has many different options. For example, blinds usually use plastic sheets or wood chips as light-shielding members, while curtains such as folding curtains, roller blinds, roman blinds, etc. are often used (4), wire or plastic. The curtains made of lines are covered with cloth to block the sunlight. Although the fabric for custom curtains can be used to weave a beautiful pattern by interweaving warp and weft, or to print a beautiful pattern directly on the woven fabric, since the woven fabric is woven from many small yarns, There is inevitably a slight gap between adjacent yarns, which causes the curtain fabric to be easily leaked when used, and the shading effect is not good. SUMMARY OF THE INVENTION An object of the present invention is to provide a curtain fabric which can produce a texture of a cloth while having a better light-shielding effect. The curtain fabric of the present invention comprises: a two-spaced cloth layer, a base film positioned between the surface layers, and at least one opaque layer attached to the base film. The beneficial effect of the invention is that the base film with the opaque layer attached to the 201242553 is formed between the surface layers of the table cloth, so that the appearance of the cloth for the curtain can maintain the texture of the cloth, and at the same time, the shading of the cloth for the curtain can be improved. effect. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. Referring to Figures 1, 2 and 3, a preferred embodiment of the fabric for curtains of the present invention can be applied to a folding curtain 2. The folding curtain 2 disclosed in Figure 2 is a folding curtain which can be folded up and down, mainly The utility model comprises: an upper handle 21, a pull-tab 22 positioned under the upper rail 21, and two pull cords 23 for pulling up the pull-tab 22, and the curtain fabric 1 of the embodiment is wrinkled It is disposed between the drawstrings 23 and can be pulled and unfolded by the drawstrings 23 to be folded and unfolded. However, the folding curtain 2 of Fig. 2 is only one of a plurality of curtains, and the curtain fabric 1 of the present invention can also be used in applications where a fabric shade is required, for example, a roller blind, a roman shade or the like. Since the improvement of the present invention is not related to the configuration of the folding curtain 2, the configuration thereof will not be described in detail. The curtain fabric 1 of the present embodiment comprises: two spaced-sheet fabric layers 1 a base film 12 between the surface fabric layers 11, and a layer attached to both side faces 121 of the base film 12, The opaque layer (1) of one embodiment may be in the form of woven fabric or non-woven fabric, that is, the woven fabric layer 11 may be woven from warp and weft, or In the form of non-woven fabric, in order to enhance the visual beauty, the surface layer 11 of the present embodiment may also be formed into a beautiful pattern by knitting, or a pattern layer may be printed on the surface of the table cloth, which is in the embodiment. Layer 1 1 is 4 201242553 with non-woven fabric. The base film 12 of the present embodiment is a soft plastic film. The material of the base film 12 is not particularly limited. In the present embodiment, polyethylene terephthalate (English: P〇1yethylene terephthalate) is used. PET) The side faces 121 of the base film 12 of the film are respectively oriented toward one of the surface layers n. The opaque layer 13 is adhered to one of the side plates 121 of the base film 12 by electroplating. It is selected from the group consisting of a galvanized layer and an aluminized layer. That is, in the embodiment, the opaque layer 139 may be a single layer outside the single layer as disclosed in the embodiment, or may be a double layer on the side faces 121 of the base film 12. The material of the base film 12 and the opaque layer 13 of the present embodiment is not particularly limited as long as the base film 12 can be folded along with the surface layer η, and the opaque layer 13 is folded. It has a light-shielding effect and can be attached to the side faces 121 of the base film 12 to achieve the intended effect of the present invention. In the manufacture of the curtain fabric i of the present embodiment, the opaque layer η′ is first formed on one of the side faces 121 of the base film 12 by electroplating, and then the combination is sandwiched in the same area. The fabric layer u and the base film (4) are joined together in the form of a bonding or a combination between the surface layers u to form the curtain fabric of the present invention. When the curtain fabric of this embodiment! At the time of use, since the base film (4) is a soft plastic film, the base film 12 does not affect the folding and unfolding of the curtain fabric 1. When the curtain is unfolded, the table is not set. The cloth layer η can exhibit the texture of the cloth, and the opaque layer 丨 3 ′ sandwiched between the surface cloth layers u can also effectively block the light cold from the gap of the surface cloth layer u, thereby improving the curtain The shading effect of .... In addition, 201242553, the opaque layer 3 formed by electroplating in this embodiment can also effectively prevent electromagnetic waves. That is, the curtain fabric 1 of the present invention not only has an innovative structure, but also provides a better light-shielding effect while maintaining the texture of the fabric, and has a function of preventing electromagnetic waves. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All remain within the scope of the invention patent.
