Problems solved by technology

It can be seen from the above prior art that the color fastness of the fabric can be improved by modifying the fabric or adding an auxiliary agent to the dye, but there are not many studies to improve its dyeability from the modification of the chlorophyll group.

Abstract

The invention provides a novel nanometer titania / chlorophyll derivative dye and a preparation method thereof. The preparation method comprises the following steps: cleaning and drying leaf stems of fresh plant; processing the leaf stems with a cupric sulfate solution to obtain a chlorophyll-stable plant raw material; then preparing the pre-treated plant raw material into plant powder; adding the plant powder into ethanol water; performing light-proof sealing and stirring; conducting ultrasonic oscillation; filtering and taking the filtrate; concentrating the filtrate to obtain a chlorophyll extracting solution; adding a sodium hydroxide and ethanol solution into the chlorophyll extracting solution to saponify chlorophyll; adding a sulfate solution; adding water for dilution; filtering to obtain a solid chlorophyll derivative; finally, dissolving the solid chlorophyll derivative into ethanol water; performing quick stirring; adding a nanometer titania solution dropwise; performing intensive stirring to obtain the nanometer titania / chlorophyll derivative dye. The prepared dye is high in absorbency, good in stability, high in water solubility and excellent in color fastness, and a fabric dyed by the dye is bright and long-lasting in color and high in wash resistance and light fastness.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a novel nano-titanium dioxide / chlorophyll derivative dye and a preparation method thereof. Background technique: [0002] Natural dyes refer to dyes obtained from plants, animals, microorganisms or mineral resources with little or no chemical processing. my country is one of the first countries to use natural dyes. Although since the birth of synthetic dyes, due to the complete color spectrum of synthetic dyes , bright color, washable and light-resistant, cheap and other reasons, natural dyes are gradually being replaced, but as people pay more and more attention to environmental protection and self-care in recent years, many synthetic dyes are easy to irritate the skin and cause skin diseases and other diseases. The dyed fabrics are unique in tone, diverse in personality, and also have some health care functions. Therefore, natural dyes that are non-toxic, h...
