Embodiment 1
[0012] (1) To prepare copper phthalocyanine pigment dispersion, add cetyltrimethylammonium chloride accounting for 15% of the pigment mass in water and fully stir to dissolve, then add copper phthalocyanine pigment, whose mass accounts for 2% of the water mass 20%, fully stirred and placed in an ultrasonic pulverizer for 60 minutes;
[0013] (2) Prepare the copper phthalocyanine pigment dyeing solution and perform exhaust dyeing on the seaweed non-woven fabric, add the above-mentioned dispersion liquid to the water so that the mass of copper phthalocyanine accounts for 0.2% of the mass of the seaweed non-woven fabric to be dyed, put the seaweed non-woven fabric In, adjust the dyeing bath ratio to 10:1, and dye at 30°C for 5 minutes; dehydrate the dyed seaweed non-woven fabric and dry it at 60°C.
[0014] It has been determined that the UV transmittance T(UVA) and T(UVB) of the undyed seaweed non-woven fabric are 23.37%, 17.04%, and the ultraviolet protection factor UPF is 5.53...
Embodiment 2
[0016] (1) To prepare copper phthalocyanine pigment dispersion, add cetyltrimethylammonium chloride accounting for 15% of the pigment mass in water and fully stir to dissolve, then add copper phthalocyanine pigment, whose mass accounts for 2% of the water mass 20%, fully stirred and placed in an ultrasonic pulverizer for 60 minutes;
[0017] (2) Prepare the copper phthalocyanine pigment dyeing solution and perform exhaust dyeing on the seaweed non-woven fabric, add the above-mentioned dispersion liquid in water so that the copper phthalocyanine pigment accounts for 1% of the mass of the seaweed non-woven fabric to be dyed, put the seaweed non-woven fabric In, adjust the dyeing bath ratio to 10:1, and dye at 30°C for 8 minutes; dehydrate the dyed seaweed non-woven fabric and dry it at 60°C.
[0018] It has been determined that the ultraviolet transmittance T(UVA) and T(UVB) of the undyed seaweed nonwoven fabric are 23.37%, 17.04%, and the ultraviolet protection factor UPF is 5....
Embodiment 3
[0020] (1) To prepare copper phthalocyanine pigment dispersion, add cetyltrimethylammonium chloride accounting for 15% of the pigment mass in water and fully stir to dissolve, then add copper phthalocyanine pigment, whose mass accounts for 2% of the water mass 20%, fully stirred and placed in an ultrasonic pulverizer for 60 minutes;
[0021] (2) Prepare the copper phthalocyanine pigment dyeing solution and perform exhaust dyeing on the seaweed non-woven fabric, add the above-mentioned dispersion liquid to the water so that the copper phthalocyanine pigment accounts for 3% of the mass of the seaweed non-woven fabric to be dyed, put the seaweed non-woven fabric In, adjust the dyeing bath ratio to 10:1, and dye at 30°C for 10 minutes; dehydrate the dyed seaweed non-woven fabric and dry it at 60°C.
[0022] It has been determined that the ultraviolet transmittance T(UVA) and T(UVB) of the undyed seaweed non-woven fabric are 23.37%, 17.04%, and the ultraviolet protection factor UPF...
