Abstract

A method for treating mercerized cotton for incorporating ultraviolet radiation protection into the mercerized cotton is disclosed which comprises the steps of placing the mercerized cotton into a solution of Zn(II), removing the mercerized cotton from the solution, and washing the mercerized cotton. Other methods for treating cotton for protection from ultraviolet radiation are also disclosed.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for treating mercerized cotton for incorporating ultraviolet radiation protection into the mercerized cotton comprising the steps of:
 placing the mercerized cotton into a solution of Zn(II);   removing the mercerized cotton from the solution; and   washing the mercerized cotton.   
     
     
         2 . The method of  claim 1  further comprising the step of drying the mercerized cotton. 
     
     
         3 . The method of  claim 1  wherein the solution of Zn(II) comprises zinc acetate dissolved in water. 
     
     
         4 . The method of  claim 3  wherein the solution of Zn(II) further comprises 4.39 g. of zinc acetate (20 mmol) dissolved in 100 mL of deionized water. 
     
     
         5 . The method of  claim 3  wherein the solution of Zn(II) further comprises 4.39 g. of zinc acetate (20 mmol) dissolved in 100 ml of distilled water. 
     
     
         6 . The method of  claim 1  wherein the solution of Zn(II) comprises zinc acetate dissolved in water and amine added added to the zinc acetate dissolved in water. 
     
     
         7 . The method of  claim 6  wherein the amine comprises ethanolamine, ethylenediamine, or (tris)hydroxymethylaminomethane. 
     
     
         8 . The method of  claim 1  wherein the solution of Zn(II) comprises zinc sulfate heptahydrate, sodium chloride, and sodium hydroxide. 
     
     
         9 . The method of  claim 8  wherein the zinc sulfate heptahydrate comprises 5.75 g. zinc sulfate heptahydrate (20 mmol), the sodium chloride comprises 0.88 g (15 mmol) sodium chloride, and the sodium hydroxide comprises 1.6 g. (40 mmol) sodium hydroxide. 
     
     
         10 . A method for treating cotton for incorporating ultraviolet radiation protection into the cotton comprising the steps of:
 placing the cotton into a concentrated mercerization strength NaOH solution;   placing the cotton into a solution of Zn(II);   removing the cotton from the solution of Zn(II); and   washing the cotton.   
     
     
         11 . The method of  claim 10  further comprising the step of drying the cotton. 
     
     
         12 . The method of  claim 10  wherein the solution of Zn(II) comprises zinc acetate dissolved in water. 
     
     
         13 . The method of  claim 12  wherein the solution of Zn(II) further comprises 4.39 g. of zinc acetate (20 mmol) dissolved in 100 mL of deionized water. 
     
     
         14 . The method of  claim 12  wherein the solution of Zn(II) further comprises 4.39 g. of zinc acetate (20 mmol) dissolved in 100 ml of distilled water. 
     
     
         15 . The method of  claim 10  wherein the solution of Zn(II) comprises zinc sulfate heptahydrate, sodium chloride, and sodium hydroxide. 
     
     
         16 . The method of  claim 15  wherein the zinc sulfate heptahydrate comprises 5.75 g. zinc sulfate heptahydrate (20 mmol), the sodium chloride comprises 0.88 g (15 mmol) sodium chloride, and the sodium hydroxide comprises 1.6 g. (40 mmol) sodium hydroxide. 
     
     
         17 . A method for treating cotton for incorporating ultraviolet radiation protection into the cotton comprising the steps of:
 placing the cotton into a concentrated mercerization strength NaOH solution;   placing the cotton into a solution of Zn(II);   placing the cotton into a solution of NaOH;   removing the cotton from the solution of NaOH; and   washing the cotton.   
     
     
         18 . The method of  claim 17  further comprising the step of drying the cotton. 
     
     
         19 . The method of  claim 17  wherein the solution of Zn(II) comprises zinc acetate dissolved in water. 
     
     
         20 . The method of  claim 17  wherein the solution of Zn(II) comprises zinc sulfate heptahydrate, sodium chloride, and sodium hydroxide.
