preparation example Construction

[0022] A method for preparing antibacterial polyacrylonitrile fibers, comprising the following steps: step 1, preparation of modified polyacrylonitrile fibers; step 2, preparation of aminated polyacrylonitrile fibers containing aldehyde groups; step 3, preparation of acrylic antibacterial fibers;

[0023] In the first step, the polyacrylonitrile fiber is put into the alkaline solution of lower alcohol, soaked at 20°C-100°C for 2h-10h, then the fiber is taken out and put into the organic amine solution, and soaked at 40°C-120°C Soak at ℃ for 0.5h-20h, take out the fiber, wash and dry it, and you can get the modified polyacrylonitrile fiber;

[0024] In the second step, the modified polyacrylonitrile fiber is put into the organic solution containing polyaldehyde groups to make it completely submerged, and soaked at 20°C-100°C for 2h-10h, the fiber is taken out, washed and dried. Obtain the aminated polyacrylonitrile fiber containing aldehyde group;

[0025] In the third step, t...

Embodiment 1

[0027] (1) Put 1g of acrylic fiber into a mixed solution of 45ml of methanol, 55ml of water and 1g of sodium hydroxide, soak it at 20°C for 2h, then take out the fiber and put it into diethylenetriamine solution, soak it at 40°C for 0.5 h, taking out the fiber for washing and drying to obtain a modified polyacrylonitrile fiber;

[0028] (2) Put the modified polyacrylonitrile fiber into a glutaraldehyde solution containing 0.1% hydrochloric acid to completely immerse it, and soak it at 20°C for 2 hours, take out the fiber, wash it, and dry it to obtain the aldehyde-based polyacrylonitrile fiber;

[0029] (3) add 0.85g silver nitrate and 0.85g sodium hydroxide in 500ml water, adjust the pH value of this solution with ammoniacal liquor subsequently to be 8, configuration obtains the alkali solution of silver nitrate; Put the fiber gained in step (2) into this silver nitrate and adding polyethylene glycol with a volume fraction of 0.1%, taking it out after soaking at room temperat...

Embodiment 2

[0031] (1) Put 1g of acrylic fiber into a mixed solution of 99ml of ethylene glycol, 1ml of water and 20g of sodium hydroxide, soak it at 100°C for 10h, then take out the fiber and put it into the solution of triethylenetetramine, at 120°C Soak for 20 hours, take out the fiber, wash and dry to obtain the modified polyacrylonitrile fiber;

[0032] (2) Put the modified polyacrylonitrile fiber into a glucose solution containing 0.5% hydrochloric acid to make it completely submerged, and soak it at 100°C for 10 hours, take out the fiber, wash it, and dry it to obtain the aldehyde-based polyacrylonitrile fiber;

[0033] (3) add 1.7g silver nitrate and 1.7g sodium hydroxide in 1L water, adjust the pH value of this solution with ammoniacal liquor subsequently and be 9, configuration obtains the alkaline solution of silver nitrate; Put the fiber gained in step (2) into this silver nitrate and adding 1.0% polyvinylpyrrolidone by volume fraction, soaking at room temperature for 1 hour, ...

Abstract

The invention discloses a method for preparing a polyacrylonitrile antibacterial fiber. The method comprises the following steps: firstly, adding polyacrylonitrile fiber into an alcoholic-alkaline solution, performing surface treatment, and subsequently adding an organic amine solution for chemical modification so as to obtain a modified polyacrylonitrile fiber; secondly, adding the modified polyacrylonitrile fiber into an organism solution containing multiple aldehyde groups so as to obtain aminated fiber containing aldehyde groups; finally, soaking the fiber into a silver nitrate solution, washing, and drying, thereby obtaining the polyacrylonitrile antibacterial fiber. The polyacrylonitrile antibacterial fiber prepared by the method is excellent in antibacterial property and good in washablity, and antibacterial components have low probability of dropping off; meanwhile, the method is smart in idea, simple in production process and very good in industrial production property, and the polyacrylonitrile antibacterial fiber can be used as an antibacterial filter for sterilization of air and water bodies, and meanwhile has wide application prospects in clothing textiles and medical sterilization products.

Description

technical field [0001] The invention belongs to a preparation method of polyacrylonitrile antibacterial fiber, in particular to a preparation method of antibacterial fiber with simple preparation method, excellent antibacterial performance and stable performance. Background technique [0002] With the enhancement of consumers' health awareness, the new generation of people's demand for health products is also gradually increasing. Among all the antibacterial products that have been applied, antibacterial fiber is a new generation of environmentally friendly and healthy products, and antibacterial fiber is a material with a very wide range of applications in functional textiles. There are generally two methods for preparing antibacterial fibers: 1. Adding antibacterial components to the polymer solution, and then performing solution spinning to obtain antibacterial fibers. The production process of this method is complicated and the scope of use is limited; 2. The antibacter...
