The invention discloses a copper-molybdenum lamination etching liquid composition for a panel, which comprises the following components in percentage by mass: 5 to 20 percent of hydrogen peroxide, 5 to 13 percent of organic carboxylic acid, 5 to 13 percent of organic alkali, 0 to 0.4 percent of electrochemical copper inhibitor, 0 to 2 percent of hydrogen peroxide stabilizer, 0 to 0.4 percent of organic phosphonic acid containing hydroxyl and / or amino substituted carbon atoms, and 50 to 83 percent of deionized water. According to the copper-molybdenum lamination etching liquid composition for the panel, a predetermined content of organic phosphonic acid containing hydroxyl and / or amino substituted carbon atoms is added, and the organic phosphonic acid and the electrochemical copper inhibitor are used for optimizing the potential difference between copper and molybdenum together, so that the undercut problem caused by the increase of over-etching time is solved. The invention further discloses an etching method based on the copper-molybdenum lamination etching liquid composition for the panel.

The invention relates to a method for improving a shirt collar and preventing the collar from collapsing, the shirt collar comprises a stand collar and a lapel, the center line of the stand collar and the lapel is divided into a right stand collar and a right lapel by XY, and the improvement of the front collar comprises the following steps: 1, making a vertical line of O1D through a point D, intersecting the vertical line at a point E, and cutting the vertical line to the point D along an ED line; 2, anticlockwise rotating DCE by taking a point D as an axis, and upwards moving a point C to a point C1; the AM line moves upwards along the XY line and is set as A1M1, 1.0 cm < = O1A1 < = 1.4 cm, and an arc line is connected with a new right stand collar; 3, making a new stand collar C2M1C1A1; fourthly, the BK line moves upwards along the XY line to be set as B1K1, O2B1 is larger than or equal to 1.8 cm and smaller than or equal to 2.2 cm, and the K1LSB new right turn-down collar is connected through an arc line; 5, making a new left lapel K1L2S2B1, and integrally combining the new right lapel and the new left lapel to form a new lapel; improving the casual collar; the warpage and radian of the stand collar and the turn-down collar of the shirt are changed, the shirt is suitable for being worn on different occasions, it is guaranteed that the neckline is always kept round and smooth, the neckline is not prone to collapse after being washed, the whole shirt is flat after being worn, the collar embraces the neck, and the appearance is attractive.
