Description

Stain remover and preparation method thereof Technical Field The invention relates to the technical field of daily chemical washing, in particular to a dyeing stain remover and a preparation method thereof. Background In modern society, with the improvement of living standard, people increasingly rely on washing machines to clean clothes, and the clothes are not manually cleaned like the past. However, the problem of color cross-over of clothing has plagued many households, especially cotton-containing clothing. In laundry, if the laundry is not classified by color, light-colored laundry may be stained with stain due to cross-color. Especially for white clothes containing cotton, many people like to wear the clothes, but if the clothes are not noticed during cleaning, the white clothes can be stained with dyeing stains. Once the garment is stained, it becomes very difficult to dispose of, and many people choose to discard it, wasting a lot of reusable garments. Currently, three main methods for removing dyeing stains are bleach water, hydrogen peroxide and sodium hydrosulfite. However, in practical application, the bleaching water has great influence on the color and clothes, the clothes can be damaged, sulfur odor exists when the sodium hydrosulfite is used, the original color of the clothes can be changed, the hydrogen peroxide has obvious bleaching effect only when the temperature is higher than 70 ℃, and the color of the whole clothes can be lightened. The titanyl sulfate is a dye fading agent used in textile industry, and the titanyl sulfate solution is easy to hydrolyze and lose the fading effect on the dye, and the solution needs to be prepared at present for use. The stain remover can solve the problem that titanyl sulfate is easy to hydrolyze, has better effect than that of single titanyl sulfate, and can improve the stain removing effect. Disclosure of Invention In order to overcome the technical defects of the existing products, the invention provides a stable liquid stain remover, and discloses a stain remover and a preparation method thereof. The invention adopts the following technical scheme that the dyeing stain remover comprises the following components in percentage by mass: Composition of the ingredients 15% -20% Of titanyl sulfate Phytic acid 5-15% 0.5 To 3 percent of ammonium bifluoride And the balance of deionized water. Further, in the stain remover, the phytic acid is 70-80% in content. Further, the preparation method of the stain remover comprises the following specific steps: Weighing, namely accurately weighing raw materials according to the formula proportion for standby; The preparation method comprises the steps of dissolving phytic acid and ammonium bifluoride in deionized water, then adding titanyl sulfate for multiple times, completely dissolving titanyl sulfate for each addition, and filtering to obtain a finished product. The stain remover can prevent the hydrolysis of the titanyl sulfate, can enhance the fading effect of the titanyl sulfate on the dye, and has good stain removing effect. Detailed Description The inventor of the invention discovers that when the mass ratio of the titanyl sulfate to the phytic acid to the ammonium bifluoride is 15-20:5-15:0.5-3, the hydrolysis of the titanyl sulfate can be prevented, the fading effect of the titanyl sulfate on the dye can be enhanced, and the solution formed after mixing has a good removal effect on dyeing stains. The present invention will be further specifically described with reference to examples, but the present invention is not limited to these examples. The specific embodiment of the invention is as follows: Example 1 The dyeing stain remover is prepared according to the proportion in the table I, wherein the dyeing stain remover is prepared by mass percent. The preparation method comprises the following steps: the preparation method comprises the steps of dissolving phytic acid and ammonium bifluoride in deionized water, then adding titanyl sulfate for multiple times, stirring until the titanyl sulfate is completely dissolved in each time, and filtering to obtain a finished product. List one Examples 2 to 5 are prepared according to the proportion shown in Table I, wherein the percentages are mass percentages, and the difference between the proportions of the titanyl sulfate, the phytic acid and the ammonium bifluoride are 15 to 20:5 to 15:0.5 to 3. Comparative example 1A stain remover was different from examples 1 to 6 in that it did not contain phytic acid and ammonium bifluoride, and was prepared in the proportions shown in Table II, in which the percentages are by mass.
