BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fabric, artificial leather, artificial leather, and film sheet for automobile interior materials, and in particular, having various colors using laser etching equipment. To form a pattern. More specifically, in the method of manufacturing a fabric for automobile interior materials and the like, various pattern patterns are formed by using the color under the layer to be etched using laser etching.

Conventionally, the fabric used as a car trim cover was mainly fabric, artificial leather, artificial leather or film sheet, and the color and pattern expression method for the fabric was as follows. For example, in the case of the fabric, weaving the fiber yarn in a desired pattern using a weaving machine to express the color and pattern of the fabric according to the color of the fiber yarn and the position and direction of the fiber yarn weave, and additionally the color Silver dyeing or printing (print), etc. were also used, and the pattern was expressed by using an emboss roll or by etching with NaOH solution. In the case of artificial leather, artificial leather and film sheets, colors and patterns were expressed by coating synthetic resins such as PU, acrylic or PVC using emboss rolls or release papers, and gravure rolls. A gravity roll print method was also used.

However, as described above, the method of expressing color and pattern by weaving fiber yarns using a weaving machine has a limitation in expressing a pattern that can be woven with the original color of the fiber yarn, It was difficult to form a pattern pattern. In addition, since the method of using the embossed roll or the release paper is also used to form a pattern by using the embossed relief, it is difficult to express a pattern with a large variation of the intaglio relief, and the manufacturing process is complicated and it is difficult to form various color pattern patterns. There was a problem. In addition, since the method of etching with NaOH solution is a wet etching method, there is a serious problem that the precision is significantly reduced in accurate pattern representation, and the process of washing the NaOH solution after the etching must be performed. It has the disadvantage of generating.
