The Application Of Savageness Food Coloring Matters On Wool Dyeing

The Application of Savageness Food Coloring Matters on Wool Dyeing Savageness food coloring matter were root in nature and applied to food pigmentation, showing that safety,nature.The savageness food coloring matter was increasingly got consumer's favors.With the development of science,more and more savageness coloring matters were exploit by researcher.The savageness coloring matters used to textiles dyeing could be built a new concept that different from the synthetic dyestuff built.The seven kind coloring food matters Kaoliang Color,Red rice red,lac dye red, carminic,Gardenia Blue,Gardenia Yellow,sodium copper chlorophyllin were studied on this paper.They were all used to wool dyeing and the emphases were carried out as the listing:(1)The influence that the water solution properties of coloring matter on temperature, PH,the stability of metal ion.(2)The effect of the value of PH and temperature on coloring matter solution.(3)The studied of the property of coloring matter pigmentation.Such as best the value of PH,rate of pigmentation,uniformity of pigmentation,the dosage of coloring matter and so on.(4)The application of intermediate dyeing agents on dyeing technology,such as the choice of agent,the use of dosage,the deal with intermediate dyeing and so on.(5)Estimate on the color endurance and the discussion of color make up.The results were shown as following:First,different coloring matters would show different characters when the concentration of solution,the value of PH,and the kind of metal ion were changed.When the dyeing was gone on under the condition of wool, the properties of coloring matter were steadily.All of the seven kinds coloring matters could be used to dye on wool.Secondly,the pigmentation property of coloring matter was similarity to that of acid color.The adsorption property were conformed with the Longermuer adsorption.Thirdly,seven kind coloring matters need intermediate dyeing action of metal ion thus come true the color fastness.The Aluminium sulfate, Zinc sulfate,Ammonium iron(â…¡)sulfate,Calcium chloride all could be used as intermediate dyeing reagents on account of their conformed with the standardization of nature.Fourthly,seven kind coloring matters could be made up color that include much chromatogram,and the black would be dye successfully when the seven kind coloring matters were pieced together.
