Abstract
The invention provides a process for preparing a purely natural dye. The process for preparing the purely natural dye comprises the following steps of: a, preparing raw materials, namely collecting fresh plants, cleaning, cutting and airing; b, impregnating; c, heating and filtering; d, extracting dye solution; and e, refining the dye solution to obtain concentrated dye solution. In the process for preparing the purely natural dye, abundant green plants are taken as the raw materials, so production cost is reduced; the dye is environmental-friendly and does not have any toxic or side effect; meanwhile, the dyed clothes have natural faint scent and are beneficial to human bodies, so the dye is an environmental-friendly natural dye worthy of popularization.
Description
Technical field
The present invention relates to a kind of preparation technology of dyestuff, especially a kind of natural phant that utilizes is dye material, belongs to field of printing and dyeing.
Background technology
In recent years, very deeply concerned to the imbalance of the deterioration of environmental quality and the eubiosis in the world, the mankind are faced with since the dawn of human civilization serious environmental crisis, and are in environmental pollution, most of directly relevant with the pollution of industrial and Industrial products.What use on the market now all is chemical dye, and the part chemical dye constitutes a threat to HUMAN HEALTH, and some azoic dyestuffs can be decomposed into the aromatic amine of poison in chemical dye, and pentachloro-, chlorophenol also have some dyestuffs easily to cause allergic.European Union member countries begin the legislation about the forbidding azoic dyestuff, and the outlet textiles all will be subjected to strict environmental certification inspection.Vegetable dye is not only nontoxic, belongs to real Green Product, and has many-sided medicinal health care function, has catered to that the modern goes back to nature, the consumer psychology of health body-building.Vegetable dye is to be raw material with plants such as the distinctive herbal medicine of China, flowers, tealeaves, fruit, refines the natural plant dyestuff that forms through all multiple operation such as pulverizing, immersion, boiling; It does not conform to any chemical substance, and is nontoxic, and textiles, clothes with its printing and dyeing forms can not cause any harm to HUMAN HEALTH.But the traditional plant dyestuff is not suitable for the requirement of modern industry, production that can't be a large amount of, and soaping fastness and light fastness are on the low side, and technology falls behind, and for some cotton fabrics colouring difficulties, Color is poor especially.
Summary of the invention:
At the demand, the invention provides a kind of preparation technology of pure natural dyestuff, by rational technological design and procedure arrangement, guaranteed the colouring power of natural plant dye on cotton fabric, fabric after the dyeing can reach the standard of printing and dyeing, color even has certain soaping fastness and light fastness.
The present invention is a kind of preparation technology of pure natural dyestuff, and the step of preparation process of this pure natural dyestuff comprises: a. gets the raw materials ready, and collects fresh plant and cleans, cuts off, dries; B. flood; C. heating and filtering; D. extract dye liquor; E. refine dye liquor, obtain dye concentrated solution at last.
In a preferred embodiment of the present invention, in the described step (a), fresh plant is Berberine tree root, Cortex Juglandis, hispid arthraxon and lichen four kind of plant.
In a preferred embodiment of the present invention, the mass percent of described four kind of plant is 35: 30: 20: 15.
In a preferred embodiment of the present invention, in the described step (b), get and get the raw materials ready 2 kilograms, 10 liters in water, the time of dipping is 3 hours.
In a preferred embodiment of the present invention, in the described step (c), the time of heating is 1.5 hours, and temperature is controlled at more than 100 ℃, obtains rough dye liquor after the filtration.
In a preferred embodiment of the present invention, in the described step (d), in rough dye liquor, add powdered sodium carbonate 20 gram and hydrochloric acid 20ml, heating and temperature control is at 60 ℃, and be 60 minutes heat-up time, extracts dye liquor after cooling.
In a preferred embodiment of the present invention, be 20 minutes described cooling time.
In a preferred embodiment of the present invention, in the described step (e), the dye liquor heating that step (d) is extracted is refined, obtain the concentrated dye liquor of 100ml at last, heating the spissated time therebetween is 2 hours.
The present invention has disclosed a kind of preparation technology of pure natural dyestuff, this preparation technology utilizes green plants as raw material, the abundant raw material abundance, reduced production cost, and environmental protection, have no side effect, clothes after the printing and dyeing has natural faint scent simultaneously, and is useful to health, is a kind of green natural dyestuff that is worthy to be popularized.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
