Abstract

The invention relates to the technical field of textile fabric afterfinish, and in particular relates to a cotton fabric nano-silver antibacterial production method. The method comprises the following steps of: dissolving and preparing a potassium persulfate solution by adopting deionized water, wherein the weight ratio of the potassium persulfate solution to the deionized water is 1 to (6-8), heating to be 60 DEG C, soaking a cotton fabric into the potassium persulfate solution for 20-30 minutes, wherein the bath ratio is 1 to (10-15); grafting cotton by adopting methacrylamide, and enabling the cotton to be coordinated with silver ions with hollow orbits through electron-rich group amido bonds on a graft-methacrylamide molecules. The adsorbability of cotton fibers to the silver ions is increased, wherein the escherichia coli and staphylococcus bacteriostasis rates reach 99.9%, the fabric has excellent antibacterial property, and the silver content retention rate of the grafted cotton nano-silver antibacterial fabric is 75.23% after the fabric is washed for a plurality of times, so that the fabric has good washability. Additionally, the method has the advantages of simple production technology, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of after-finishing of textile fabrics, in particular to a method for producing cotton fabric nano-silver antibacterial. Background technique [0002] With the development of society, people have higher and higher requirements for clothing fabrics, and more and more functional requirements for safe and efficient antibacterial clothing. Because silver has a strong antibacterial ability unmatched by other metals, it has a strong killing effect on bacteria, fungi, Escherichia coli and staphylococcus. When the diameter of silver particles is reduced to nanometer size, the surface area is greatly increased, the activity is enhanced, and the antibacterial function is also enhanced. Among them, the use of nano-silver in antibacterial cotton fabrics can make the nano-silver particles fast to adsorb between the fibers of the cotton fabric and on the surface of the cotton fabric, and the antibacterial effect is very g...
