Embodiment 1

[0033] A non-static high-efficiency filter fiber material, the microporous fiber non-woven fabric containing chitin is used as the upper surface layer and the lower surface layer, and the polydopamine coating containing enzyme molecules is used as the middle layer.

[0034] The microporous fiber non-woven fabric is woven by using single fibers as wefts and warps, and the weaving pores of the single fibers are 2 μm, and each warp and weft is composed of one single fiber.

[0035] The single fiber uses polyvinyl alcohol as the inner layer and chitosan as the outer layer. The diameter of the single fiber is 0.3 μm, wherein the diameter of the polyvinyl alcohol is 60% of the diameter of the single fiber, that is, 0.18 μm.

[0036] The preparation method of the single fiber comprises the following steps:

[0037] Step 1, adding 100 g of polyvinyl alcohol to 1 L of distilled water and stirring to form a dissolved solution, and performing a vacuum distillation reaction for 30 min to...

Embodiment 2

[0052] A non-static high-efficiency filter fiber material, the microporous fiber non-woven fabric containing chitin is used as the upper surface layer and the lower surface layer, and the polydopamine coating containing enzyme molecules is used as the middle layer.

[0053] The microporous fiber non-woven fabric is woven by using single fibers as wefts and warps, the weaving pores of the single fibers are 10 μm, and each warp and weft is composed of 5 single fibers.

[0054] The single fiber uses polyvinyl alcohol as the inner layer and chitosan as the outer layer. The diameter of the single fiber is 0.7 μm, wherein the diameter of the polyvinyl alcohol is 80% of the diameter of the single fiber, that is, 0.56 μm.

[0055] The preparation method of the single fiber comprises the following steps:

[0056] Step 1, adding 200 g of polyvinyl alcohol to 1 L of distilled water and stirring to form a dissolved solution, and performing a reaction under reduced pressure for 60 min to ...

Embodiment 3

[0071] A non-static high-efficiency filter fiber material, the microporous fiber non-woven fabric containing chitin is used as the upper surface layer and the lower surface layer, and the polydopamine coating containing enzyme molecules is used as the middle layer.

[0072] The microporous fiber non-woven fabric is woven by using single fibers as wefts and warps, and the weaving pores of the single fibers are 8 μm, and each warp and weft is composed of 3 single fibers.

[0073] The single fiber uses polyvinyl alcohol as the inner layer and chitosan as the outer layer. The diameter of the single fiber is 0.5 μm, wherein the diameter of the polyvinyl alcohol is 70% of the diameter of the single fiber, that is, 0.35 μm.

[0074] The preparation method of the single fiber comprises the following steps:

[0075] Step 1, adding 150 g of polyvinyl alcohol to 1 L of distilled water and stirring to form a dissolved solution, followed by distillation under reduced pressure for 40 min t...

Abstract

The invention relates to the field of air filtration, in particular to a preparation method of a non-static high-efficiency filter fiber material, which uses chitin-containing microporous fiber non-woven fabrics as the upper surface layer and the lower surface layer, and polydopamine coating as the middle layer, and is compounded and a specific preparation method is provided. The invention solves the problem that the service life of the existing electrostatic filter material is not long, uses polycondensation pores of polyvinyl alcohol as the microporous structure, realizes high-efficiency filtering effect, and does not contain electret.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to a preparation method of a non-static high-efficiency filter fiber material. Background technique [0002] Air pollution can not only have destructive effects on surrounding objects through physical, chemical and biological erosion, but also through the respiratory system (lungs), skin epidermis and other parts of the polluted gas to our respiratory system, nervous system, immunity, skin, Liver, endocrine system, etc. produce toxic effects. At the same time, it can affect people's mental state, prone to fatigue, tension and other adverse reactions, reducing the efficiency of work and study. Living and working in an environment with poor air quality for a long time will not only lead to decreased respiratory function and aggravated respiratory symptoms, but also lead to chronic bronchitis, bronchial asthma, emphysema and other diseases, and even lead to lung cancer and nasopharyngeal...
