Problems solved by technology

[0002] The climate in the south is humid, especially in hot and humid rainy weather. Bacteria are easy to grow on towels. At present, the main component of towels is cotton, which is soft in texture, but basically only has the effect of removing stains, cleaning and cooling, and cannot protect the skin very well. effect
Even some towels have antibacterial effect, but the antibacterial persistence rate is not high

Abstract

The invention relates to the field of fiber manufacturing, in particular to a preparation method of nano cuprous oxide@copper oxide / stone needle fiber. The preparation method comprises the following specific steps of 1) dissolving stone needle powder and soluble copper salt in deionized water according to a mass ratio of (3-5): 1, ultrasonically dispersing for 30-60 minutes, and marking as a suspension A; 2) adding 4-6 mol / L of strong base into the solution A, magnetically stirring for 10-30 minutes until the solution A is uniform, and marking as a suspension B; (3) adding a weak reducing agent into the suspensions, wherein the molar ratio of the weak reducing agent to the soluble copper salt is 1: (1.5-2.5), centrifugation is conducted after magnetic stirring is conducted for 30-60 min, washing is conducted for multiple times with deionized water and ethyl alcohol, and a product C is obtained; and 4) dispersing the product C in 100mL of hydrogen peroxide with the mass fraction of 10-20%, magnetically stirring for 6-10 hours, centrifuging, and drying at 60-80 DEG C for 0.5-2 hours to obtain the nano cuprous oxide@copper oxide / stone needle. The nano antibacterial cuprous oxide@copper oxide / stone needle material has a relatively good antibacterial effect, the antibacterial rate is greater than 98%, and the sterilization rate is greater than 96%.

Description

technical field [0001] The invention relates to the field of fiber manufacturing, in particular to a preparation method, product and application of nano-cuprous oxide@copper oxide / bianstone fiber for towels. Background technique [0002] The climate in the south is humid, especially in hot and humid rainy weather. Bacteria are easy to grow on towels. Currently, the main component of towels is cotton, which is soft in texture, but basically only has the effect of removing stains, cleaning and cooling, and cannot protect the skin very well. effect.
