Embodiment 1
[0028] Dissolve 0.3993g of copper acetate monohydrate in 100ml of absolute ethanol, then add 0.4g of PVP, the solution turns green; heat the water bath to 78°C, add 5ml of deionized water dropwise, and add 7ml of 0.2 M sodium carbonate solution, neutralization reaction for 15 minutes, to obtain nano-copper oxide complex.
[0029] See attached figure 1 , which is the XRD diffraction pattern of copper oxide provided in this example, compared with the standard card (PDF # 48-1548), it proves that the obtained product is pure phase copper oxide.
[0030] See attached figure 2 , which is a TEM image of the copper oxide provided in this example; the figure shows that the particle size distribution of the product provided in this example is between 2 and 6 nm, and the dispersion is good.
[0031] The obtained copper oxide product is directly diluted 80 times, the cotton textiles are antibacterially finished by dipping technology, and the cotton textiles with antibacterial function...
Embodiment 2
[0035] Dissolve 0.7986g of copper acetate monohydrate and 0.4g of PVP in 100ml of absolute ethanol, heat in a water bath to 78°C, add 5ml of deionized water dropwise, and then add 7ml of 0.2M sodium carbonate solution dropwise after 15min, and react for 15min. The resulting product is directly diluted 100 times, and the padding process is used to carry out antibacterial finishing on chemical fiber textiles.
Embodiment 3
[0037] Dissolve 0.3993g of copper acetate monohydrate and 0.4g of PEG in 100ml of absolute ethanol, heat in a water bath to 78°C, add 5ml of deionized water dropwise, and then add 7ml of 0.2M sodium carbonate solution dropwise after 15min, and react for 15min. The resulting product is directly diluted 50 times, and the spray process is used to carry out antibacterial finishing on silk and wool blended textiles.

Abstract
The invention discloses a preparing method and application of a self-dispersal nanometer copper oxide complexing body, and belongs to the technical field of inorganic nanometer material synthesis. The method comprises the steps that copper acetate and the macromolecule complexing body are dissolved in ethyl alcohol to build an even macromolecule complexing body, the obtained mixed solution is heated until ebullition and added with water dropwise, when the solution turns from green to brownish black, an appropriate alkaline solution is added into the solution dropwise to conduct neutralization, the reaction is conducted for a certain time, and the nanometer copper oxide complexing body is obtained. According to the preparing method, the particle size of a synthetized copper oxide nanometer particle is between 2 nm and 6 nm, the particle has good dispersity in an aqueous solution, the dispersoid is applied to textile finishing without the need of adding adhesive, and the obtained product has excellent and lasting antibiotic property.
Description
technical field [0001] The invention relates to a preparation method for directly synthesizing a self-dispersing nano-copper oxide complex from an ethanol solution with copper acetate in the presence of a polymer complexing agent and its application in the textile field, belonging to the technical field of inorganic nanomaterial preparation and textile printing and dyeing . [0002] technical background [0003] With the development of society, people's pursuit of quality of life is increasing day by day, and traditional fabrics can no longer meet people's production and living needs. Therefore, the processing of fabrics with special functions has attracted extensive interest of researchers. Among them, antibacterial treatment has become a research hotspot in recent years. Since the last century, people have been using organic antibacterial agents to treat fabrics, but organic antibacterial agents have poor thermal stability and poor broad-spectrum. Therefore, people's att...
