Embodiment 1
[0015] a. Get 10g of nitrogen-containing methylol reactive group silsesquioxane (POSS-H) and dissolve it in 100mL of methanol to prepare nitrogen-containing methylol reactive group silsesquioxane methanol solution (POSS-H) H methanol solution).
[0016] b. Take 50 g of the above POSS-H methanol solution, 15 g of magnesium chloride, and 5 g of citric acid (which has the effect of controlling pH), mix them with water, and make 1 L of finishing solution.
[0017] c. Put the pure cotton fabric in the finishing solution with a padder for two dipping and two rolling, the excess rate is 75%, pre-baking at 80°C for 3min, and then baking at 120°C for 1.5min, to obtain the silsesquioxane-containing (POSS) Cellulose-based nanocomposite fabrics of particles. During the preparation process, POSS-H had a cross-linking reaction with the cellulose in the pure cotton fabric, and the reaction equation was as follows figure 2 shown.
[0018] Such as image 3 As shown, the infrared spectrum ...
Embodiment 2
[0021] a. Dissolve 10g of POSS-H in 100mL of methanol to obtain POSS-H methanol solution;
[0022] b. Take 50g of the above-mentioned POSS-H methanol solution, 15g of magnesium oxide, and 5g of citric acid, and mix them with water to make a finishing solution with a volume of 1L;
[0023] c. Put the pure cotton fabric in the finishing liquid with a padder for two dipping and two rolling, the excess rate is 75%, then pre-baking the padded fabric at 80°C for 3min, and then baking at 140°C for 1.5 minutes. min, the cellulose-based nanocomposite fabric containing silsesquioxane particles was obtained.
[0024] Such as image 3 As shown, the infrared spectrum (H-2 curve) of the product shows: the -OH characteristic absorption peak in the cellulose molecule is 3470cm -1 The absorption becomes weak; in the infrared spectrum at 1650cm -1 and 810cm -1 It is the Si-O- absorption peak. After testing, the latitude and longitude elastic recovery angle of the product has increased from...
Embodiment 3
[0027] a. Dissolve 10g of POSS-H in 100mL of methanol to obtain POSS-H methanol solution;
[0028] b. Take 50g of the above-mentioned POSS-H methanol solution, 15g of magnesium oxide, and 5g of citric acid, and mix them with water to make a finishing solution with a volume of 1L;
[0029] c. Put the pure cotton fabric in the finishing liquid with a padder for two dipping and two rolling, the excess rate is 75%, then pre-baking the padded fabric at 80°C for 3min, and then baking at 150°C for 1.5 minutes. min, the cellulose-based nanocomposite fabric containing silsesquioxane particles was obtained.
[0030] The infrared spectrum of the product shows that the -OH characteristic absorption peak in the cellulose molecule is 3470cm -1 The absorption becomes weaker, in the infrared spectrum at 1650cm -1 and 810cm -1 It is the Si-O- absorption peak. After testing, the latitude and longitude elastic recovery angle of the product has increased from 107.65 degrees to 156.98 degrees....
