According to the present invention, the extraction process is simple; the extraction efficiency of the method provided by the present invention is higher than the extraction efficiency in the prior art; the extraction process does not cause environmental pollution; the extract provides good color fastness for protein fibers; the color fastness to light can be 5-6 grade, the color fastness to washing can be 5-6 grade, the color fastness to dry wearing can be 5-6 grade, the color fastness to wet wearing can be 4-5 grade; the medicinal value of the persimmon is beneficial to the human body.
Description
Technical field
The present invention relates to the fabrics printing and dyeing field, be specifically related to a kind of colouring method that utilizes the persimmon natural dye to textiles.
Background technology
On human history, natural dye has been made indelible contribution for beautifying people's life.Since 19 end of the centurys, because developing rapidly of synthetic dyestuffs makes natural dye withdraw from the textile dyeing field basically.Along with the continuous enhancing of human environmental consciousness and to self healthy growing interest, the part synthetic dyestuffs are more and more noticeable to the harm that human health and ecological environment are produced.Under global green revolution tide, natural dye begins again to be paid attention to by people.The animals and plants dyestuff is by extracting in the organism in the natural dye, and is good, biodegradable with Environmental compatibility.Natural dye is a Chinese medicine mostly, and in dyeing course, its medicine and flavor component are absorbed by fabric with pigment, and except that the dyeing function, natural dye also has multiple functions such as medicine, spices, makes the fabric after the dyeing to human body special medicinal health-care function arranged.
The pharmacological effect of persimmon: cool blood, stop blooding, moisten the lung and relieve the cough, antihypertensive, can treat sore to external application, nameless sores or boils disappears.One Chinese patent application 200710040546.X discloses the colouring method of a kind of persimmon on textiles; It has adopted ripe dying and two kinds of methods of ingrain; And the weathering color fastness that discloses through the textiles of its method dyeing can reach the 4-5 level, and Washing reaches the 3-4 level.Yet the waste of the method for extracting pigment of the poach that it adopts is more, and indexs such as the concentration of extract are difficult to accurate control, and also there is certain weak point in its colouring method.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide a kind of colouring method that utilizes the persimmon natural dye to textiles, promptly from red persimmon fruit, extracts natural dye, and is applied to textile dyeing.
Show that after deliberation the persimmon fruit extract is bright-coloured bronzing, its maximum absorption wavelength is about 490～500nm.Protein fibre or fabric are had good dyeability, handle to obtain various colors through different mordants, and COLOR FASTNESS is good, is the natural plant dye of a function admirable.
For realizing above-mentioned purpose, the invention provides a kind of colouring method that utilizes the persimmon natural dye to textiles, may further comprise the steps:
(1) preparation persimmon natural dye: persimmon fresh fruit or dry fruit are cleaned, dried, mechanical disintegration; With persimmon fruit crushed material join pH value 8-10, concentration of volume percent is a refluxing extraction in the 40-60% ethanol water, the mass ratio of persimmon fruit crushed material and ethanol water is 1: 40; Extract is warming up to 95 ℃, insulation 1-2h; It is extract original volume 1/8-1/10 that filtration and decompression distillation make the concentrate volume, the persimmon fruit natural dye that obtains concentrating; The pH value of said ethanol water is to regulate to add an amount of sodium acid carbonate, sodium carbonate or sodium phosphate;
(2) mordant dyeing in advance: real silk or wool fabric are carried out preparatory mordant dyeing processing, and controlled condition is during processing: mordant weight is the 1-5% of pollutant weight, and bath raio is 1: 10-50, and temperature is 85 ℃, the time is 50min; The taking-up fabric that disposes is cleaned, and extracts; Said mordant is one or more in ferric sulfate, iron chloride, ferrous sulfate, frerrous chloride, aluminium chloride, aluminum sulfate, alum or cerous sulfate, the neodymium chloride;
(3) preparation dye liquor: persimmon fruit natural dye and water to concentrate are configured to dye liquor, wherein concentrate the 30-40% that dyestuff accounts for whole dye liquor quality, and regulate dye liquor pH value 4-6;
(4) dyeing: the preparatory mordant dyeing fabric treated of above-mentioned warp immersed in the persimmon fruit dye liquor dye, controlled condition is during dyeing: the ratio 1 of pollutant weight and dye liquor volume: 10-50, temperature 80-100 ℃, time 45-80min; Dye complete, the washing, the oven dry.
Beneficial effect of the present invention is:
The present invention adopts ethanol-aqueous slkali circumfluence method from the persimmon fruit, to extract natural dye, and extraction process is simple, and the additive method of the obvious prior art of extraction efficiency, leaching process can not cause environmental pollution;
Extract is good to the protein fibre dyefastness; Its weathering color fastness can reach the 5-6 level, and Washing reaches the 5-6 level, and the unlubricated friction COLOR FASTNESS can reach the 5-6 level, and the wet-milling COLOR FASTNESS can reach the 4-5 level;
The dyeing back uses the environmental protection mordant to handle can increase chromatogram; Dyeing back fabric color is soft, wears safety, do not have carcinogenic, teratogenesis or cause allergic reaction, and the medical value of persimmon itself is to the human body beneficial;
Good, biodegradable with the ecological environment compatibility;
And utilize the persimmon fruit to prepare the natural dye low price, and having made full use of natural resource, market prospects will be very wide.
