Embodiment 1
[0059] The present embodiment provides a kind of preparation method of titanium dioxide polyester composite fiber material, comprises the following steps:
[0060] 15g of titanium dioxide particles with a particle diameter of about 50nm are heated to 100 degrees to obtain high-temperature nano-titanium dioxide particles; 85g of polyester fiber material is placed in a container, and the container is placed in an oven at 70 degrees; Titanium dioxide particles are sprayed into the container with the hot air flow at a spray speed of 0.5m / s, and after circulating in the container for 5 hours, solidify and cool to obtain a titanium dioxide polyester composite fiber material, nano titanium dioxide particles are embedded in polyester fibrous materials such as figure 1 shown.
[0061] After measurement, in the titanium dioxide polyester composite fiber material, the loading capacity of nano titanium dioxide particles is 10% of the polyester fiber material mass; the specific surface ar...
Embodiment 2
[0063] The present embodiment provides a kind of preparation method of titanium dioxide polyamide composite fiber material, comprises the following steps:
[0064] 8g of titanium dioxide particles with a particle diameter of about 100nm were heated to 120 degrees to obtain high-temperature nano-titanium dioxide particles; 92g of polyamide fiber membranes were placed in a container, and the container was placed in an oven at 80 degrees; Titanium dioxide particles are sprayed into the container with the hot air flow at a spray speed of 0.4m / s, and after circulating in the container for 2 hours, solidify and cool to obtain a two-dimensional titanium dioxide polyamide composite fiber material, in which nano titanium dioxide particles are embedded in polyamide fiber membrane.
[0065] After measurement, in the titanium dioxide polyamide composite fiber membrane, the loading capacity of the nanometer titanium dioxide particles is 4.5% of the mass of the polyamide fiber membrane; the...
Embodiment 3
[0067] This embodiment provides a method for preparing a silica-polyacrylonitrile composite fiber material, comprising the following steps:
[0068] 10g of silicon dioxide particles with a particle size of about 120nm are heated to 150 degrees to obtain high-temperature nano-silica particles; 90g of polyacrylonitrile fibers are placed in a container, and the container is placed in an oven at 80 degrees; The high-temperature nano-silica particles are sprayed into the container with the hot air flow at a spray speed of 0.3m / s, and after circulating in the container for 3 hours, they are solidified and cooled to prepare a one-dimensional silica-polyamide composite. In the fiber material, the nano silicon dioxide particles are embedded in the polyacrylonitrile fiber material, and the one-dimensional silicon dioxide polyacrylonitrile composite fiber material is woven into a three-dimensional silicon dioxide polyacrylonitrile composite fiber net.
[0069]After measurement, in the si...
