Embodiment 1
[0035] Use 3-mercaptopropyltriethoxysilane KH-580 to modify cotton fabric, and react with water-based photocurable polyurethane acrylate to make cotton have good anti-wrinkle function. The specific steps are:
[0036] (1) Pre-processing:
[0037] ① Prepare a mixed solution of 20g / L sodium hydroxide and 5g / L Pingping plus O, and roughen the cotton fabric for 45 minutes at 70°C;
[0038] ② Prepare 5 wt% ethyl acetate solution of 3-mercaptopropyltriethoxysilane (KH-580), put the roughened cotton fabric into the above solution, and shake at 30°C for 3 hours;
[0039] ③Take out the cotton fabric, wash it with distilled water, and dry it under vacuum at 60°C.
[0040] (2) Finishing:
[0041] ① Prepare a mixed solution of 5wt% water-based polyurethane acrylate and 5wt% 3-mercaptopropyltriethoxysilane, ultrasonically oscillate, then add 1wt% photoinitiator, and ultrasonically oscillate;
[0042] ②Put the cotton fabric flatly in the above finishing solution, with a bath ratio of 1:50,...
Embodiment 2
[0044] Use 3-mercaptopropyltriethoxysilane KH-580 to modify cotton fabric, and react with water-based photocurable polyurethane acrylate to make cotton have good anti-wrinkle function. The specific steps are:
[0045] (1) Pre-processing:
[0046] ①Prepare 20g / L sodium hydroxide aqueous solution, 5g / L Pingping plus O, and roughen the cotton fabric for 45min at 70°C;
[0047] ② Prepare 5 wt% ethyl acetate solution of 3-mercaptopropyltriethoxysilane (KH-580), put the roughened cotton fabric into the above solution, and shake at 30°C for 3 hours;
[0048] ③Take out the cotton fabric, wash it thoroughly in distilled water, and dry it under vacuum at 60°C.
[0049] (2) Finishing:
[0050] ① Prepare a mixed solution of 10wt% water-based polyurethane acrylate and 5wt% 3-mercaptopropyltriethoxysilane, fully ultrasonically oscillate, then add 1wt% photoinitiator, and ultrasonically oscillate;
[0051] ②Put the cotton fabric flatly in the above finishing solution, with a bath ratio of...
Embodiment 3

[0054] (1) Pre-processing:
[0055] ①Prepare 20g / L sodium hydroxide aqueous solution, 5g / L Pingping plus O, and roughen the cotton fabric for 45min at 70°C;
[0056] ② Prepare 5 wt% ethyl acetate solution of 3-mercaptopropyltriethoxysilane (KH-580), put the roughened cotton fabric into the above solution, and shake at 30°C for 3 hours;
[0057] ③Take out the cotton fabric, wash it thoroughly in distilled water, and dry it under vacuum at 60°C.
[0058] (2) Finishing:
[0059] ① Prepare a mixed solution of 15wt% water-based urethane acrylate and 5wt% 3-mercaptopropyltriethoxysilane, fully ultrasonically oscillate, then add 1wt% photoinitiator, and ultrasonically oscillate;
[0060] ②Put the cotton fabric flatly in the above finishing solution, with a bath ratio of 1:5...
