Background

Along with the continuous progress of society and the improvement of living standard of people, the requirements of people on textiles are more and more diversified, various special fibers and functional fabrics are produced, and special finishing fabrics such as three-proofing easy-decontamination finishing, aromatherapy finishing, moisture absorption quick-drying, skin-friendly, cool feeling, mite prevention and the like become favorite for people. However, the application of the textile on removing peculiar smell and refreshing air does not enter the public sight.

Indoor air pollutants such as formaldehyde released by furniture and the like can cause diseases and discomfort, peculiar smells such as indole and the like in a toilet can also make people feel uncomfortable, and fresh air can be enjoyed indoors at any time, so that luxury is gradually achieved, and therefore, some people with high income can purchase equipment such as an air purifier and the like to purify indoor air. However, the price of the air purifier is high, and the filter screen needs to be replaced frequently, so that the cost is high; on the other hand, the air purifier has strong maintenance and repair speciality and can be completed only by contacting a manufacturer, and the possibility of operation of a user is low. Therefore, although the air purifier has good effect of removing air pollutants such as formaldehyde, the popularization of the air purifier is still difficult.

Formaldehyde removal rate test

As shown in figures 1 and 2, 7 identical cubic glass experiment chambers for simulating indoor environment are assembled and numbered in a way of (i) - (c), an object placing port is arranged on the experiment chamber, the experiment chamber can form a closed space after the object placing port is sealed, and the sizes of the inner cavities of the experiment chamber are all 0.25m³The top of the experiment chamber is provided with a fan which is electrically connected with the outside, the experiment chamber is also provided with a liquid inlet hole for injecting formaldehyde solution and a sampling hole for collecting air in the experiment chamber, valves are arranged at the positions of the liquid inlet hole and the sampling hole, the liquid inlet hole is connected with a liquid storage tank through a pipeline and a pump, the sampling hole is connected with a sampler through a pipeline, odor removing fabrics prepared in examples 1-3 and comparative examples 1-4 with the same size are respectively hung in the experiment chambers from (i) - (c), and then 37% of formaldehyde solution is injected into the experiment chamber, so that the formaldehyde content in the experiment chamber reaches 5mg/m³And during the test, the visible light illumination is ensured, the fan is turned on, the sampling hole is opened at regular time to sample for 5min according to 1L/min, the formaldehyde concentration is detected by using a formaldehyde tester after the color developing agent is added into the sampling liquid in the sampler, and the detection method is carried out according to GB/T15516 acetylacetone spectrophotometry for measuring air quality formaldehyde in the sampling liquid. The test result is shown in fig. 3, and it can be seen that the removal effect of formaldehyde in the experiment chambers No. 1-3 is better. Since the cotton fiber used in comparative example 1 was not TiO-modified₂After treatment, the final formaldehyde removal rate can only reach 42.65 percent, the odor removal effect is not ideal, which indicates that TiO₂The contribution of the treatment to the formaldehyde treatment is the greatest. Comparative example 2 lacking the deodorizing procedure of step (6), the formaldehyde removal rate was the lowest in the first hour, but lacking TiO₂The fabric treated or not using the mint fiber still has certain odor removal effect for the first hour, which shows that the initial formaldehyde removal is mainly contributed by the odor removal process in the step (6),TiO₂second time, the mint fibers contributed less to the early formaldehyde purification, indicating that the TiO attached to the fabric₂The better formaldehyde treatment effect can be achieved after a period of illumination, and the mint fiber can release the mint components better after a period of use. Comparative example 3 the pretreatment effect was better, at 1h, at a level equivalent to that of examples 1-3, but the methane removal rate began to decrease due to the lack of release of mint components at the later stage.

Fabric washability test

The fabric prepared in the embodiment 1-3 is washed (washed and dried) for 10 times, and the formaldehyde content after 12 hours is tested according to the formaldehyde removal rate test method after each treatment. The test result is shown in fig. 4, and it can be seen that the formaldehyde removal effect of the odor removal fabric of the invention still maintains a high level after multiple times of water washing, which indicates that the odor removal fabric of the invention has good washing fastness, and this is also related to that the microcapsules of the mint fibers are released and broken along with the washing friction.

Although the present invention has been described in detail by referring to the drawings in connection with the preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made on the embodiments of the present invention by those skilled in the art without departing from the spirit and scope of the present invention, and these modifications or substitutions are within the scope of the present invention/any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
