preparation example Construction
[0023] The preparation method of above-mentioned anti-ultraviolet fabric fabric is as follows:
[0024] a Dissolve polyester particles in N-N dimethylformamide solvent in an oil bath at 50°C-80°C, stir evenly to prepare a polyester solution with a mass ratio of 1:5.
[0025] b After dissolving and stirring evenly, weigh the coffee powder according to the mass ratio of coffee powder and polyester 2:10—5:10, add it into the polyester solution and stir it to make it evenly distributed. It is 0.5μm-5μm.
[0026] c Apply the above-mentioned prepared mixed solution evenly on the inner layer of the fabric to form an anti-ultraviolet layer of 0.05mm-0.3mm, and then dry it to obtain an anti-ultraviolet fabric.
Embodiment 1
[0028] According to the above process steps: accurately weigh 10g of polyester particles and 50g of N-N dimethylformamide solvent respectively, stir and mix evenly in an oil bath at 50°C, add 5.0g of coffee powder with a particle size of 0.5μm, and stir After being uniform, it is directly coated on the inner layer of the polyester fabric to form an anti-ultraviolet layer with a thickness of about 0.3mm, and the anti-ultraviolet fabric is obtained after standing and drying.
[0029] The anti-ultraviolet performance test of this anti-ultraviolet fabric fabric shows that its ultraviolet protection factor (UPF) is 94.5, and its UVA transmittance is 3.84%, which is especially suitable for making summer sun umbrella umbrellas.
Embodiment 2
[0031] According to the above process steps: accurately weigh 10g of polyester particles and 50g of N-N dimethylformamide solvent respectively, stir and mix evenly in an oil bath at 65°C, add 4.0g of coffee powder with a particle size of 3.0μm, and stir After being uniform, it is directly coated on the inner layer of the polyester fabric to prepare an anti-ultraviolet layer with a thickness of about 0.2mm, and the anti-ultraviolet fabric is obtained after standing and drying.
[0032] The anti-ultraviolet performance test of this anti-ultraviolet fabric fabric shows that its ultraviolet protection factor (UPF) is 71.6, and its UVA transmittance is 4.35%, which is especially suitable for making car sunscreen and rainproof cloth.
