Embodiment 1

[0029] 0.1 g of triethylenetetramine having a number average molecular weight of 1000 was dissolved in 99.8 g of water. Then add 0.1g of esterquat 31441-1 and stir evenly to prepare an impregnation solution with 99.8% by mass of water, 0.1% of triethylenetetramine and 0.1% of esterquat 31441-1. Put 1 g of carboxypolyacrylonitrile cation exchange fibers into the soaking liquid, and the solid-to-liquid mass ratio is 1:100. At 1°C, stir once every 10 minutes, and stir for 2 minutes each time. After soaking in this way for 4 hours, remove and shake off excess water, and dry with hot air at 30°C to obtain the fiber with the function of removing formaldehyde according to the present invention. Material, the percentage content of each component of the fiber material with the function of removing formaldehyde is: carboxypolyacrylonitrile cation exchange fiber 88.95%, ester-based quaternary ammonium salt 31441-1 surfactant 0.05%, triethylenetetramine 11% .

That is, the fiber material with formaldehyde removal function described in the present invention is obtained. The percentage content of each component of the fiber material with the function of removing formaldehyde is: 24.8% of carboxypolyacrylonitrile cation exchange fiber, 0.2% of alkylphenol polyoxyethylene ether OP-10 surfactant, polyalkylene ...

Embodiment 3

[0035] Dissolve 2g of triethylenetetramine with a number average molecular weight of 30,000 in 93g of water, then add 5g of fatty alcohol polyoxyethylene ether AEO-9 and stir evenly. Prepare an impregnating solution with a mass percentage of 93% water, 2% triethylenetetramine and 5% fatty alcohol polyoxyethylene ether AEO-9. Put 4 g of carboxypolyacrylonitrile cation exchange fibers into the impregnation solution, and the solid-to-liquid mass ratio is 1:25. At 20°C, stir once every 15 minutes, and stir for 2 minutes each time. After soaking in this way for 2.5 hours, remove and shake off excess water, and dry with hot air at 60°C. That is, the fiber material with formaldehyde removal function described in the present invention is obtained. The percentage content of each component of the fiber material with formaldehyde removal function is: carboxypolyacrylonitrile cation exchange fiber 80.9%, fatty alcohol polyoxyethylene ether AEO-9 surfactant 0.1%, triethylenetetramine 19%....

Abstract

The invention discloses a fibrous material with a formaldehyde removal function, and belongs to the technical field of poisonous volatile matter removal. Cation exchange fibers are used as base body materials in the fibrous material, and counting the total mass of the fibrous material by 100%, the fibrous material comprises, by mass, 24.8%-88.95% of the cation exchange fiber, 0.05%-0.2% of surface active agent, and 11%-75% of macromolecule organic amine compound. The preparation method of the fibrous material includes the following steps: (1) preparing steeping liquor according to proportion, (2) adding fibers into the steeping liquor and evenly stirring the fibers, (3) soaking the fibers in the steeping liquor for 2-4 hours under the condition of interval stirring, (4) and fishing out the soaked materials, drying the materials with hot air or natural air. The fibrous material is diversified in application form, has no secondary pollution, and is large in formaldehyde adsorption capacity, high in adsorption speed, simple in preparation process, and low in cost.

Description

technical field [0001] The invention relates to a fiber material with the function of removing formaldehyde, which belongs to the technical field of eliminating toxic volatiles. Background technique [0002] Under normal circumstances, formaldehyde is a colorless gas with a suffocating smell, which has a strong irritating effect on human eyes and respiratory system. Modern scientific research shows that formaldehyde has negative effects on human health. Its degree of harm is closely related to its concentration in the air and the length of contact time. There are relatively large individual differences in the perception of formaldehyde by various organs of the human body. Among them, the eyes are the most sensitive to formaldehyde, followed by the sense of smell and the respiratory tract. When the concentration of formaldehyde in the air is low, the stimulating effect is slight, and when it is slightly higher, the stimulating effect is enhanced. It is generally believed t...
