Problems solved by technology

However, after the water purification treatment is completed, because the particle size of the general photocatalyst is generally between tens of nanometers to hundreds of nanometers, the photocatalyst and water must be separated by a filter membrane. However, after long-term use , the pores of the filter membrane will be filled by the photocatalyst and blockage is likely to occur. At this time, the water purification device must be shut down before the membrane is replaced, which will increase the cost of the entire purification process and greatly reduce the purification efficiency.
[0006] At present, although the industry has applied photocatalysts to non-rigid carriers such as fibers or fabrics, most of these products are used to improve the sterilization and self-cleaning capabilities of the products themselves, and no one has ever applied them to any purification. method or device

Embodiment 1

[0058] [Example 1] Preparation of composite fiber (core-sheath type) containing photocatalyst

[0059] According to the volume ratio of the first part and the second part is 70:30, and PET is used as the first part and a mixture containing PET and titanium dioxide (based on the total weight of the mixture, the weight ratio of PET and titanium dioxide is 99:1) as Second part, carry out composite spinning step again, to make the composite fiber that contains the photocatalyst with the cross-sectional diameter of 0.2mm, then this composite fiber that contains photocatalyst is cut, finally obtains the short fiber that contains photocatalyst with the length of 5mm fiber.

[0060] [Methylene blue fading test]

[0061] The short fiber containing photocatalyst that is made by this embodiment 1 is placed in the concentration of 20mL and is 10ppm methylene blue solution (methylene blue, manufactured by Japan Katayama chemical company), then irradiates ultraviolet light, to observe meth...

Embodiment 2

[0064] [Example 2] Production of light-guiding bundled fibers containing photocatalyst

[0065] According to the volume ratio of the first part and the second part is 80:20, and with PMMA as the first part and the mixture containing PMMA and titanium dioxide (based on the total weight of the mixture, the weight ratio of the PMMA and titanium dioxide is 99:1) as The second part is to carry out the composite spinning step again to obtain the composite fiber containing the photocatalyst with a cross-sectional diameter of 0.2mm, then the composite fiber containing the photocatalyst is bundled and cut, and finally obtained with a length of 10cm Light-guiding bundled fibers containing photocatalysts.

[0066] [Methylene blue fading test]

Abstract

It was a composite fiber with Photocatalyst, containing the first organic polymer as the first part and the mixture of the first, the second organic polymer and a Photocatalyst as the second part. The second part was paralleled or coated in the first part. The first and second organic polymer can be the same or different, which elected respectively from polyester, polycarbonate, polyamide, polyolefin, polyacrylate, polyvinyl alcohol, polyvinyl chloride, polyvinyl fluoride, Polystyrene and a combination of these. Another preparation of composite fiber with Photocatalyst and purification methods of contaminated fluid using it was contained in this invention. The invention was the composite fiber with Photocatalyst which can make anchor Photocatalyst stable, effectively increase the efficiency of photocatalytic reaction, prolong service life and be reused.

Description

【Technical field】 [0001] The present invention relates to a kind of composite fiber containing photocatalyst (photocatalyst) and its preparation method and its application, especially refers to a kind of composite fiber which has the effect of stably fixing photocatalyst and effectively exerting the reaction efficiency of photocatalyst. A photocatalyst-containing composite fiber prepared by silk (bicomponent spinning), and a method for purifying polluted fluid using the photocatalyst-containing composite fiber. 【Background technique】 [0002] In recent years, due to the discovery that photocatalyst has the functions of sterilization, antifouling, air purification, deodorization, etc., it has become a popular product in the industry, and the various effects produced are collectively referred to as "photocatalyst effect". [0003] "Photocatalyst reaction" is the irradiation of ultraviolet light or sunlight, so that the electrons on the surface of the photocatalyst absorb enoug...
