Embodiment 1

[0019] (1) 200 g of Bi with an average particle size of 120 nm 0.895 Yb 0.1 Er 0.005 OBr powder, 300 g nano-silica, 10 g polyether modified polysiloxane wetting agent and 490 g polyamide pellets are mixed and put into the extruder, and the working temperature of the extruder is 200 Extrude at ℃, and obtain functional pellets after pelletizing.

[0020] (2) Add the functional pellets obtained in (1) into the pellets, in which the functional masterbatch accounts for 4% by mass, put it into the extruder after mixing, extrude at 230°C, and spin Silk obtains infrared light to degrade toxic gases in indoor curtain fibers.

[0021] Embodiment 1 gained curtain fiber material property, and see with other material fiber contrast figure 1 . It can be seen that under visible light irradiation, compared with other fibers, the fiber obtained in Example 1 has the highest degradability; and under infrared light: other materials will not degrade formaldehyde at all, but the fiber obtained...

Abstract

The invention discloses a preparation method of curtain fibers capable of degrading indoor toxic gas by utilizing visible light and infrared light. The preparation method comprises the following steps: (1) uniformly mixing Bi0.895Yb0.1Er0.005OBr powder, nano silicon dioxide, a polysiloxane wetting agent and granular materials and then putting the mixture into an extruder; extruding when the working temperature of the extruder is 190 DEG C-250 DEG C, and dicing to obtain functional granular materials; and (2) in the process of producing fibers for a curtain, adding the functional granular materials into the granular materials and uniformly mixing; then adding the mixture into the extruder, extruding by the extruder and spinning to obtain the curtain fibers capable of degrading the indoor toxic gas by the infrared light. A curtain fiber material produced by the method, disclosed by the invention, not only can utilize the visible light outside a window, but also can utilize the infrared light outside the window to effectively decompose indoor toxic and organic molecules including formaldehyde and the like.

Description

technical field [0001] The invention relates to the technical field of fibers for curtains, and relates to a preparation method of curtain fibers which utilize visible light and infrared light to degrade indoor toxic gases. Background technique [0002] With the improvement of living standards, decoration has become an essential step before moving in or using new houses and offices. However, due to reasons such as unqualified decoration materials used in the decoration process, volatile organic gases including formaldehyde, benzene, and xylene will be introduced. These toxic gases are mixed in the air and enter the human body through the respiratory tract, causing various adverse effects on the human body. It is said that indoor air pollutants such as benzene, formaldehyde, ammonia, and trichlorethylene can cause 35.7% of human respiratory diseases, 22% of chronic lung diseases, and 15% of tracheitis, bronchitis, and lung cancer. Multi-organ, multi-tissue, multi-cellular, ...
