Embodiment 1

[0043] A green preparation process for regenerating antibacterial fabrics includes the following specific preparation process: first, pure cotton fabrics are immersed in a sodium hydroxide solution with a concentration of 1 moL / L, and activated at room temperature for 20 to 40 minutes to obtain surface activation treatment Then take it out, wash it for at least 3 times, then immerse it in an aqueous solution of polyethyleneimine with a concentration of 1.5g / L, and treat it at room temperature for 30-60min to obtain a surface-loaded polyethyleneimine fabric. The surface-loaded polyethyleneimine fabric is immersed in a saturated copper nitrate aqueous solution, treated at room temperature for 5-10 minutes for complexation reaction, taken out, washed with water, and dried to prepare a regenerable antibacterial fabric.

Embodiment 2

[0045]A green preparation process for regenerating antibacterial fabrics includes the following specific preparation process: firstly, the regenerated fibers are immersed in a sodium hydroxide solution with a concentration of 1.2 moL / L, and activated at room temperature for 20 to 40 minutes to obtain a surface activation treatment Then take it out, wash it for at least 3 times, then immerse it in an aqueous solution of polyethyleneimine with a concentration of 1.6 g / L, and treat it at room temperature for 30 to 60 minutes to obtain a fabric loaded with polyethyleneimine on the surface. The surface-loaded polyethyleneimine fabric is immersed in a saturated copper nitrate aqueous solution, treated at room temperature for 5-10 minutes for complexation reaction, taken out, washed with water, and dried to prepare a regenerable antibacterial fabric.

Embodiment 3

[0047] A green preparation process for regenerating antibacterial fabrics includes the following specific preparation process: firstly, immersing nylon fabrics in a sodium hydroxide solution with a concentration of 1.4 moL / L, and performing activation treatment at room temperature for 20-40 minutes to obtain surface activation treatment Then take out and wash the fabric for at least 3 times, then immerse it in a polyethyleneimine aqueous solution with a concentration of 1.7g / L, and treat it at room temperature for 30-60min to obtain a surface-loaded polyethyleneimine fabric. The surface-loaded polyethyleneimine fabric is immersed in a saturated copper nitrate aqueous solution, treated at room temperature for 5-10 minutes for complexation reaction, taken out, washed with water, and dried to prepare a regenerable antibacterial fabric.

Abstract

The invention discloses a fabric capable of recovering antibacterial property, and an environmentally friendly preparation process thereof, and belongs to the technical field of textile products. Thepreparation process comprises: immersing a common fabric in an alkaline solution, and treating to obtain a surface-activated fabric; taking out, washing, and immersing in a polyethyleneimine aqueous solution to obtain a fabric with polyethyleneimine loaded on the surface; and taking out, washing, immersing the obtained fabric in a copper ion aqueous solution, and carrying out a complexation reaction to prepare the fabric capable of recovering antibacterial property. According to the present invention, according to the designed process route, the water is used as the reaction solvent, and the whole reaction is operated at the room temperature without the consumption of excessive energy, such that the requirements of the environmentally friendly preparation process are met; and the preparedantibacterial fabric has continuous antibacterial property, wherein the antibacterial property is reduced after the continuous use at least 9 times, and the antibacterial property can be recovered byre-immersing in the copper ion aqueous solution after the antibacterial property is reduced or eliminated, such that the fabric has the antibacterial ability throughout the life cycle so as to reducethe whole use cost of the fabric.

Description

technical field [0001] The invention relates to an antibacterial fabric, belongs to the technical field of textiles, and in particular relates to a regenerable antibacterial fabric and a green preparation process thereof. Background technique [0002] Influenza is prone to a worldwide pandemic due to its rapid pathogen mutation, rapid spread, general susceptibility to the population, and difficulty in control, posing a huge threat to the public safety of the whole society. The surface of textiles is mostly rough structure, which is easy for bacteria to attach and grow, so textiles are an effective way of spreading pathogenic bacteria. The preparation of textiles with excellent antibacterial ability is of great significance for inhibiting the growth of bacteria and the spread of diseases. [0003] Antibacterial fabrics can be obtained in two ways: one is to directly weave antibacterial fabrics with antibacterial fibers; the other is to fix the antibacterial agent on the fibe...
