Problems solved by technology

[0002] Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, and light weight, and are widely used in agricultural film, shoemaking, leather, medical and health care, mattresses, quilts, decoration, chemicals, printing, automobiles, building materials, furniture and other industries , however, during the use of traditional non-woven fabrics, especially in medical hygiene, filtration and household use, it is easier to breed bacteria and absorb pollutants, which limits its application. Therefore, the preparation of non-woven fabrics with antibacterial ability , and non-woven fabrics that can remove pollutants are particularly important. In view of this, it is necessary to study a photocatalytic non-woven fabric

Embodiment 1

[0019] A method for preparing photocatalytic non-woven fabrics by electrostatic spinning includes the following preparation steps:

[0020] S1, 2 parts of aniline, 1 part of nano titanium dioxide and 50 parts of acrylic fiber are dissolved in dimethylacetamide at 20°C to obtain a mixed solution;

[0021] S2. Use the electrostatic spinning method to spin the mixed solution to prepare a non-woven fabric. The non-woven fabric is soaked in a hydrochloric acid solution with a concentration of 1 mole per liter at 0~5°C for 24 hours, washed with water, and dried to obtain photocatalysis Non-woven fabric.

Embodiment 2

[0023] A method for preparing photocatalytic non-woven fabrics by electrostatic spinning includes the following preparation steps:

[0024] S1, 6 parts of aniline, 3 parts of nano titanium dioxide and 98 parts of polyester are dissolved in dimethylformamide at 100°C to obtain a mixed solution;

[0025] S2. Use the electrostatic spinning method to spin the mixed solution to prepare a non-woven fabric. The non-woven fabric is soaked in a hydrochloric acid solution with a concentration of 1 mole per liter at 0~5°C for 24 hours, washed with water, and dried to obtain photocatalysis Non-woven fabric.

Embodiment 3

[0027] A method for preparing photocatalytic non-woven fabrics by electrostatic spinning includes the following preparation steps:

[0028] S1, 4 parts of aniline, 2 parts of nano titanium dioxide and 70 parts of polypropylene are dissolved in medium dimethyl sulfoxide at 50°C to obtain a mixed solution;

[0029] S2. Use the electrostatic spinning method to spin the mixed solution to prepare a non-woven fabric. The non-woven fabric is soaked in a hydrochloric acid solution with a concentration of 1 mole per liter at 0~5°C for 24 hours, washed with water, and dried to obtain photocatalysis Non-woven fabric.

[0030] The scanning electron microscope image of the photocatalytic non-woven fabric prepared by electrospinning in Example 1 is as follows figure 1 As shown, it can be seen that a non-woven fabric with densely interlaced fibers is prepared by the electrostatic spinning method.

Abstract

The invention discloses a method for preparing photoelectrolytic nonwoven cloth through electrostatic spinning. The method comprises the following steps: dissolving phenylamine, nano titanium diode and a fiber material into a solvent so as to obtain a mixed solution; preparing nonwoven cloth from the mixed solution by using an electrostatic spinning method; soaking the nonwoven cloth into an acidsolution for 24 hours, washing with water, and drying, so as to obtain the photoelectrolytic nonwoven cloth. The photoelectrolytic nonwoven cloth prepared by using the electrostatic spinning method has good flexibility, can be used as gauze masks, wiping cloth, filter elements and the like, and has photoelectrolytic pollutant degradation capability.

Description

Technical field [0001] The invention relates to the technical field of fiber materials, in particular to a method for preparing photocatalytic non-woven fabrics by electrostatic spinning. Background technique [0002] Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, etc., and are widely used in agricultural film, shoemaking, tanning, medical and health, mattresses, bed and mother quilt, decoration, chemical industry, printing, automobile, building materials, furniture and other industries However, traditional non-woven fabrics are easier to breed bacteria and adsorb pollutants during the use process, especially in medical and health, filtration, and household use. This limits its application. Therefore, the preparation has antibacterial ability. , And non-woven fabrics that can remove pollutants are particularly important. In view of this, it is necessary to study a photocatalytic non-woven fabric. Summary of the invention [0003]...
