preparation example Construction

[0040] During the preparation of the additive carrier, the pollen was soaked twice in the precursor solution to ensure that the pollen was covered with a uniform layer of TiO 2 Floor;

[0041] Titanium dioxide is a semiconductor material with stable chemical properties. It generally exhibits photocatalytic performance. It is used in photocatalytic self-cleaning materials, or in papermaking, rubber and other products, and is used as a filler and colorant. In this application, it is used TiO was prepared by hydrothermal method using pollen as template 2 Hollow spheres are creatively used as additive carriers. Thanks to their special surface structure, they play a key role in the application of negative ions, far-infrared, antibacterial and mite-removing effects of composite polyester fibers.

[0056] First, rapeseed flower pollen with a diameter of 50 μm was screened out, 20 g was rinsed with alcohol, and dried; then, 9 g of Ti(SO 4 ) 2 , stirred for 20min, then added 1.2g of ammonium fluoride and 3.8g of urea to the above-mentioned deionized water, stirred for 60min, then added 20g of rape pollen to the above-mentioned deionized water, stirred for 20min, and transferred the above-mentioned deionized water to the hydrothermal In the kettle, it was hydrothermally reacted at 180°C for 20h. After the reaction, the white precipitate in the hydrothermal kettle was collected, cleaned, dried in a drying oven at 60°C for 15h, and then put into a muffle furnace. Anneal at 460°C for 2 hours, anneal at 490°C for 1 hour, and the heating rate is 2°C / min. During the annealing process, the pollen particles will be removed. After the annealing, TiO 2 Hollow sphere is the additive carrier;

The compound polyester fibers are added with a negative-ion additive, a far-infrared additive and an antibacterial and anti-mite additive, wherein the negative-ion additive, the far-infrared additive and the antibacterial and anti-mite additive respectively account for 2%, 5% and 6% by mass in the compound polyester fibers; the negative-ion additive comprises an additive carrier and tourmaline negative-ion powder; the far-infrared additive comprises an additive carrier, Tai Chi stone powder, ZrO2 nano-powder, nano-silicon dioxide, nano-aluminum oxide, nano-manganese oxide and nano-calcium oxide; the antibacterial and anti-mite additive comprises an additive carrier, nano-Cu-ZnO compound particles, nano-titanium dioxide, nano-zinc oxide and nano-silicon dioxide; and the additive carrier is TiO2 hollow spheres.

Description

technical field [0001] The present application relates to the field of polyester fibers, in particular to a negative ion, far infrared, antibacterial and anti-mite composite polyester fiber and a manufacturing method thereof. Background technique [0002] With the continuous improvement of people's living standards, consumers' demand for textiles and clothing has also changed. From the initial basic needs for covering the body and keeping warm, to today's aesthetic needs for fashion, fashion and other elements, People's pursuit has also begun to tend to environmental protection and healthy textile materials. For example, fibers with far-infrared functions can be obtained by adding far-infrared agents, and fibers with anion functions can be obtained by adding anion agents, so it is very important for the development of functional fibers. [0003] Polyester fiber usually refers to the fiber made by melt spinning of polyethylene terephthalate. It is the largest variety of synt...
