【摘要】 天然食用色素来源于大自然,用于食品着色,体现出自然、安全的概念,日益受到消费者的青睐,激发了天然色素的开发和生产。由于科学技术的发展和装备水平的提高,有更多来源的植物色素被研制、开发,为其应用于纺织品染色,实现工业化应用奠定了可靠的基础。天然食用色素用于纺织品的染色要从新的角度来重新认识,从而建立起不同于化学合成染料的新观念。本课题针对经过挑选的七种天然食用色素:高粱色素(Kaoliang Color)、红米红色素(Red rice red)、紫胶红色素(lac dye red)、胭脂红carminic、栀子蓝色素(Gardenia Blue)、栀子黄色素(Gardenia Yellow),将它们应用于羊毛纤维染色,从下面几个方面进行了研究:(1)、色素水溶液性质的研究。包括温度、pH值、金属离子对色素水溶液稳定性的影响。(2)、pH值和温度对色素溶液色光的影响。(3)、色素上染性能的研究。包括最佳染色pH值的确定,上染率、匀染性、色素用量等对色素上染性能的影响。(4)、媒染剂的应用研究。包括媒染剂的选用、媒染剂用量、媒处理对染色羊毛色光的影响等研究。(5)、色素染色羊毛织物色牢度的评价。(6)、为丰富色谱的拼色的探讨性研究。通过研究得到如下结论:(1)、不同色素,其溶液随温度、pH值、金属离子的种类会表现出不同的性质,但在羊毛纤维的染色条件下,色素溶液的性质基本稳定,所选择的七只色素都可以用来对羊毛进行染色。(2)、色素的上染性质与酸性染料类似,其对羊毛的吸附性质基本符合朗格缪尔吸附。(3)、七只色素对羊毛纤维的染色基本上需要通过金属离子的媒染作用实现固色,选择符合生态标准要求的媒染剂硫酸铝、硫酸锌、硫酸亚铁氨和氯化钙可以满足色素固色的要求。(4)、七只色素的色谱包括红、黄、蓝和棕色,利用实验所选色素,通过拼色试验,能够拼出更多色谱的颜色,甚至可以染出接近于黑色的颜色。更多还原

【Abstract】 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(Ⅱ)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.更多还原
