Abstract
The invention relates to a method for extracting natural dye based on water hyacinth. Pigment is extracted from stems, leaves and flowers of the biomass water hyacinth serving as a raw material by a Soxhlet extraction method or a water-boiling method. The method is simple, easy to operate and pollution-free. The raw material is a renewable low-carbon-source consumable product. The natural dye extracted according to the method is environment-friendly on fabric without mordant. The fabric has good color and luster, friction resistance and high color fastness.
Description
Technical field
The invention belongs to natural dyestuff and extract field, particularly a kind of natural dyestuff process for extracting based on Herba Eichhorniae.
Background technology
Synthetic dyestuff are as the main tinting material of textiles, and with its abundant colors, good dyefastness and cheap relatively price are used widely.But synthetic dyestuff are high carbon source running stores mostly based on non-renewable fossil feedstock, and its part midbody toxicity is bigger, brings pollution to environment in process of production, and dyeing waste-water is also extremely hard to manage after using; In addition, some synthetic dyestuff still have certain harm to human body, and data shows have more than 100 kind of common dyes midbody possibly produce carcinogenic substance.
Natural dyestuff comes from nature, and not only abundant raw material is renewable, and Environmental compatibility is good, biodegradable, pollution-free, is low carbon source running stores.Some natural dyestuff have pharmacological function concurrently, and therefore, natural dyestuff obtains people's very big interest recently again.At present, the positive active development of dyestuff scientific research personnel of countries in the world is based on the natural dyestuff of renewable biomass.
The Herba Eichhorniae that originates in South America is to endanger very serious perennial aquatic weed at present in the world, has extremely strong vitality and reproductivity.It is since 20th century, imported China the thirties into, and promptly the rapid spread in southern each province covers the lake in flakes, stops up the river course, shipping, irrigation and drainage, aquaculture has been produced seriously influence, and has brought serious ecology, economy and social danger.Therefore, prevent and treat its harm, develop it and have great significance as resource to bad border nature.
Summary of the invention
Technical problem to be solved by this invention provides a kind of natural dyestuff process for extracting based on Herba Eichhorniae, and this method is simple, and operation is pollution-free easily; Raw material is renewable low carbon source running stores, and the natural dyestuff that method of the present invention is extracted can carry out environmental friendliness dyeing to fabric under the condition of no mordant, and the gained fabric color is better; Colour fastness to rubbing is high.
Natural dyestuff process for extracting based on Herba Eichhorniae of the present invention comprises following two kinds of methods:
