Embodiment 1
[0018] In this embodiment, the preparation of silk fiber with formaldehyde removal function mainly includes the following steps:
[0019] (1) Dissolve 8 grams of proanthocyanidins (purity 85%) in 500 milliliters of water; then add 0.1 milliliters of glacial acetic acid to the above solution and stir evenly; then add 8 grams of ferrous sulfate and stir to dissolve it; then use bicarbonate Sodium solution adjusts the pH value of the above mixed solution to 5; then the temperature of the mixed solution is raised to 50°C, and the mixed solution is diluted after being kept warm for 20 minutes, so that the total volume of the mixed solution is 2 liters;
[0020] (2) Add 1.0 gram of flat plus 0 and 4 gram of salt in the mixed solution obtained in step (1) and stir;
[0021] (3) Add 100 grams of silk fiber into the mixed solution obtained in step (2), and treat it for 1 hour at a temperature of 90° C. and a bath ratio of 1:20; then wash and dry the silk fiber to obtain Silk fiber wit...
Embodiment 2
[0023] (1) Dissolve 10 grams of proanthocyanidins (purity 85%) in 500 milliliters of water; then add 0.15 milliliters of glacial acetic acid and stir evenly; then add 5 grams of ferrous sulfate and stir to dissolve it; then use sodium bicarbonate solution to dissolve the above The pH value of the mixed solution was adjusted to 6; then the temperature of the mixed solution was raised to 60° C., and the mixed solution was diluted to a total volume of 3 liters after being kept warm for 30 minutes;
[0024] (2) add 1.5 grams of Pingpingjia 0 and 18 grams of salt in the mixed solution that step (1) obtains, stir;
[0025] (3) Add 100 grams of silk fiber into the mixed solution obtained in step (2), and treat it for 3 hours at a temperature of 60° C. and a bath ratio of 1:30; then wash and dry the silk fiber to obtain Silk fiber with formaldehyde function. After testing, the removal rate of the silk fiber to formaldehyde in indoor air is 75.4%.
Embodiment 3
[0027] (1) Dissolve 12 grams of proanthocyanidins (purity 85%) in 500 milliliters of water; then add 0.25 milliliters of glacial acetic acid and stir evenly; then add 4 grams of ferrous sulfate and stir to dissolve it; mix the above with sodium bicarbonate solution The pH value of the solution was adjusted to 8; then the temperature of the mixed solution was raised to 55° C., and the mixed solution was diluted to 4 liters after 40 minutes of heat preservation;
[0028] (2) add 2 grams of Pingpingjia 0 and 40 grams of salt in the mixed solution that step (1) obtains, stir;
[0029] (3) Add 100 grams of silk fiber into the mixed solution obtained in step (2), and treat it for 12 hours at a temperature of 25° C. and a bath ratio of 1:40; then wash and dry the silk fiber to obtain Silk fiber with formaldehyde function. After testing, the removal rate of the silk fiber to formaldehyde in indoor air is 77.6%.
[0030] According to the specifications and quality requirements, the s...
