Example Embodiment

[0028] Example 1

[0029] 0.1 g of triethylenetetramine with a number average molecular weight of 1,000 was dissolved in 99.8 g of water. Next, add 0.1 g of ester quaternary ammonium salt 31441-1 and stir evenly to prepare an impregnating solution with 99.8% by weight of water, 0.1% of triethylenetetramine and 0.1% of ester quaternary ammonium salt 31441-1. Put 1 g of carboxypolyacrylonitrile cation exchange fiber into the impregnating liquid, and the solid-liquid mass ratio is 1:100. Stir once every 10 minutes at 1°C, and stir for 2 minutes each time. After soaking for 4 hours, remove and shake off excess water, and dry with hot air at 30°C to obtain the formaldehyde-removing fiber of 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 quaternary ammonium salt 31441-1 surfactant 0.05%, triethylenetetramine 11% .

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...
