Embodiment 1

[0028] Weigh 14.4g of cotton fabric, 9.6g of titanium sulfate and 24g of urea respectively. Cotton fabrics were washed with a solution of deionized water and absolute ethanol at a volume ratio of 1:1 at a temperature of 80 ° C for 30 min with ultrasonic vibration at 50 KHz and a power of 100 W, and then dried at 60 ° C. Dissolve titanium sulfate in 300ml of deionized water, add urea and stir vigorously, then add cotton fabric and soak for 10 minutes; put the soaked cotton fabric together with titanium sulfate urea solution into a 500ml high temperature and high pressure reactor, and fill it with deionized water To 80% of the volume of the reactor, the sealed reactor was kept at 130°C for 1.5 hours at a constant temperature. Finally, after the reaction is over, use 2g / L soap flakes, 2g / L soda ash, and a bath ratio of 1:30 to treat the cotton fabric at 90°C for 15 minutes, then wash it repeatedly with 90°C hot water and cold water, and dry it at 60°C. Dry. Figure 4 It is the ...

Abstract

The invention discloses a method for modifying the surface of cotton fabric by adopting titanium sulfate and urea, which comprises the following steps: ultrasonically oscillating and cleaning the cotton fabric to be modified at 80 DEG C, and then, drying the cotton fabric; weighing the cotton fabric and titanium sulfate according to the mass ratio of 3:2-10; weighing urea under the condition that the molar ratio of the titanium sulfate to the urea is 0.1-0.5:1; dissolving the titanium sulfate in deionized water under the condition that the volume ratio of the titanium sulfate to the deionized water is 1:6-30; adding the urea into the titanium sulfate solution, and stirring to obtain a mixed solution; soaking the cotton fabric into the mixed solution for 10-40min; putting the cotton fabric into a high-temperature and high-pressure reaction kettle for treating for 1.5-3h at the constant temperature of 130-160 DEG C; taking out the cotton fabric; washing the cotton fabric with washing liquid for 10-20min at 70-90 DEG C according to the bath ratio of 1:30-50; repeatedly washing the cotton fabric with hot water and cold water; and then, drying or naturally airing the cotton fabric to obtain the modified cotton fabric. The method of the invention is safe and pollution-free, has high production efficiency and saves raw materials; and the modified cotton fabric has good anti-ultraviolet and anti-bacterial properties and washing resistance.

Description

technical field [0001] The invention belongs to the technical field of functional textile materials, and relates to a method for modifying the surface of cotton fabrics, in particular to a method for modifying the surface of cotton fabrics by using titanium sulfate and urea. Background technique [0002] Nano-titanium dioxide materials have good photocatalytic activity and electrical properties, and have been widely used in the fields of photocatalysis, dyes, industrial catalysis, lithium-ion secondary battery materials, and photosensitized batteries. However, nano-titanium dioxide powders are easy to agglomerate, resulting in The reduction of photocatalytic activity also has a great influence on other properties. Therefore, the synthesis of monodisperse high-quality nano-TiO2 materials is the focus of people's research in recent years. At present, the methods for preparing nano-titanium dioxide powder mainly include sol-gel method, uniform precipitation method, microemulsi...
