Abstract
The invention discloses decoloration ink which comprises the following components in percentage by weight: 86-93 percent of water, 2-8 percent of thyme phenolphthalein, 3-5 percent of sodium hydroxide and 1-5 percent of NaCl. In the invention, by utilizing the characteristic that the thyme phenolphthalein is blue in an alkaline environment with a pH value of 9-12, after the ink is sprayed on a clothing material or paper, water is absorbed by fibers to ensure that the pH value of the ink becomes smaller until reaching a neutral environment, and then the ink changes from blue to colorless so as to achieve the purpose of decoloration.
Description
Technical field
The present invention relates to a kind of ink, relate in particular to a kind of ink of automatic colour killing under field conditions (factors).
