Embodiment 1
[0035] (1) The dosage of anti-mosquito finishing agent is 75g / L, of which, 10% of pyrethroid, 8% of surfactant, 2% of preservative, the balance is water, and the dosage of self-crosslinking polyether polyurethane Transtex FUN 6220 is 10g / L , prepared with water to make a finishing solution for later use;
[0036] (2) Take the weight as 115g / m 2 Knitted fabrics, padding finishing liquid, with a liquid rate of 98%. Bake at 140°C for 90s to make the polyester knitted fabric reach the setting effect, and test the permethrin content on the fabric surface after regaining moisture.
[0037] Test results: The theoretical value of permethrin content in cloth is 845mg / m 2 , the test value is 682mg / m2 , the mosquito repellent rate is 65%, and the permethrin content of the cloth surface after washing 10 times is 612mg / m 2 .
Embodiment 2
[0039] (1) The dosage of anti-mosquito finishing agent is 85g / L, of which, 10% pyrethroid, 10% surfactant, 1.5% preservative, the balance is water, the dosage of cross-linking agent EDOLAN AB is 40g / L, hydrophilic linear copolymerization The amount of silicone oil TranSoft TF-4991A is 30g / L, and it is prepared with water to make a finishing solution for later use;
[0040] (2) Take the weight as 152g / m 2 For polyester knitted fabrics, the padding finishing solution has a liquid retention rate of 75%. Bake at 140°C for 60s to shape the polyester knit, and test the permethrin content of the fabric surface after regaining moisture.
[0041] Test results: The theoretical value of permethrin content in cloth is 969 mg / m 2 , the test value is 826mg / m 2 The mosquito repellent rate is 68%, and the permethrin content of the cloth surface after washing 10 times is 779mg / m 2 .
Embodiment 3
[0043] (1) The dosage of anti-mosquito finishing agent is 115g / L, of which, 10% pyrethroid, 9% surfactant, 1% preservative, the balance is water, the dosage of cross-linking agent EDOLAN AB is 55g / L, hydrophilic linear copolymerization The amount of silicone oil TranSoft TF-4991A is 30g / L, the amount of moisture-absorbing and perspiration agent TF-620H is 20g / L, and the finishing liquid is prepared with water for later use;
[0044] (2) Take the weight as 152g / m 2 The polyester knitted fabric was padded with the finishing solution for 10 minutes, and the liquid retention rate was 47%. The material was further removed, and it was dried by drum drying at high temperature, and baked at 140°C for 5 minutes. After regaining moisture, the chlorine content of the cloth surface was tested. Permethrin content.
[0045] Test results: The theoretical value of permethrin content in cloth is 821 mg / m 2 , the test value is 830mg / m 2 , the mosquito repellent rate is 70%, and the permethri...
