Embodiment 1
[0031] Weigh 2g each of the polyester fabric and butyl titanate respectively, wherein the polyester fabric is washed with deionized water and 95% absolute ethanol solution with a volume ratio of 1:1 at a temperature of 60°C for 15min under the condition of 28KHz power 300W, 80°C Drying; butyl titanate was dissolved in deionized water at a ratio of 1:120; then the polyester fabric was immersed in butyl titanate aqueous solution for 1 min, and dimethyl sulfoxide was weighed according to 0.5% of the fabric weight, and added Add the polyester fabric together with the butyl titanate solution into a 200ml high-temperature and high-pressure reactor, and fill it with deionized water to 60% of the volume of the reactor, and put the sealed reactor at 180°C Treat at constant temperature for 2 hours; after the reaction is over, wash with 2g / L soap flakes and 2g / L soda ash solution at a bath ratio of 1:30 at 70°C for 10 minutes, then repeatedly wash with 80°C hot water and cold water, and l...
Embodiment 2
[0034] Weigh 6g of polyester fabric and 2g of butyl titanate respectively, wherein the polyester fabric is washed with deionized water and 95% absolute ethanol solution at a temperature of 90°C with a volume ratio of 1:1 and ultrasonic vibration washing at 28KHz and 300W for 15min. Dry at 80°C; dissolve butyl titanate with deionized water at a ratio of 1:80; then immerse the polyester fabric in butyl titanate aqueous solution for 5 minutes, weigh dimethyl sulfoxide according to 1% of the fabric weight, And add it to the butyl phthalate solution, add the polyester fabric together with the butyl titanate solution to a 200ml high-temperature and high-pressure reactor, and fill it with deionized water to 80% of the reactor volume, and put the sealed reactor at 200 Constant temperature treatment at ℃ for 1 hour; after the reaction is over, wash with 2g / L soap flakes and 2g / L soda ash solution at a bath ratio of 1:40 at 90℃ for 20min, then wash repeatedly with 80℃ hot water and cold ...
