When water soaks the paper during painting, the paper is easy to wrinkle and break, and once the dye is stained on the paper, it will be firmly adsorbed on the paper, and at the same time, the paper will absorb part of the color. This feature has two disadvantages: 1. Watercolor dyes cannot be drawn from Erase on the paper, so the watercolor pattern cannot be changed; 2. Because the drawing paper absorbs part of the dye, the color of the pattern after drying is lighter than when it was originally painted

Abstract
The invention relates to water color canvas and the processing method thereof. When a water color pattern is printed on the surface of the water color canvas made according to the processing method, the water color pattern has bright colors and can be modified at will depending on requirements. The water color canvas comprises a basic material of which a clear adhesive coat, a bottom coat and a face coat are in turn covered on the surface and is characterized in that the basic material is textile fabric. The specific processing steps are that: the clear adhesive layer, the bottom coat and the face coat are respectively made, the clear adhesive layer is coated on the surface of the textile fabric and dried in an oven in which the temperature is kept between 100 to 120 DEG C, then the bottom coat is coated on the surface of the clear adhesive layer and dried in the oven in which the temperature is kept between 60 to 70 DEG C, then the bottom coat is coated again and dried in the oven in which the temperature is kept between 65 to 80 DEG C, then the face coat is coated on the surface of the bottom coat and dried in the oven in which the temperature is kept between 80 to 100 DEG C, the speed at which the textile fabric passes through the oven is 6 to 6.5 m/s, at last the textile fabric with four coats is calendered.
Description
(1) Technical field [0001] The invention relates to a watercolor canvas, and the present invention also relates to a processing method of the watercolor canvas. (2) Background technology [0002] Traditional watercolor painting uses watercolor paper as the medium. When water soaks the paper during painting, the paper is easy to wrinkle and break. Once the dye is stained with the paper, it will be firmly adsorbed on the paper, and the paper will absorb part of the color. This feature has two disadvantages: 1. Watercolor dyes cannot The watercolor pattern cannot be changed since it is wiped off the paper; 2. Since the drawing paper absorbs part of the dye, the color of the pattern after drying is lighter than when it was originally painted. (3) Contents of the invention [0003] Aiming at the deficiencies of the existing watercolor paper, the present invention provides a watercolor canvas, the watercolor pattern painted on its surface is bright in color and can be modified ...
