Abstract
The invention provides a vegetable dye containing ethanol extracts of Chinese fanpalm seeds and further provides a preparation method thereof. The vegetable dye can be used for dyeing cotton, linen, silk, man-made fiber and the like and is especially suitable for finished garment dyeing. The vegetable dye can be directly used for dyeing in silk. By using the vegetable dye for dyeing, dyed fabrics are pure and brilliant in color, and each fastness can meet requirements of the national standard. Using amount of the vegetable dye can be freely adjusted according to requirements on shade. When the vegetable dye is used for dyeing the cotton, the linen and the man-made fiber, cationic graft can be firstly performed, and improvement of color yield and various fastness indexes of the fabrics is facilitated. The vegetable dye is environment-friendly and high in comprehensive utilization rate and is an ideal green product.
Description
Technical field
The invention belongs to field of printing and dyeing, be specifically related to a kind of vegetable dye, prepare the method for this dyestuff and apply this vegetable dye fabric is dyeed.
Background technology
At present, in field of printing and dyeing, particularly in clothes water washing dyeing field, pursue ecological, environmental protective, back to nature becomes new fashion, people had both pursued style and the effect of ready-made clothes, more pursue natural, ecological, allow harmony between man and nature development.Along with increasing people pays close attention to self health more, pursuing green product and green consumption has become a kind of important demand.Natural dyestuff is because the color natures such as its dyeing and weaving thing, dress ornament, graceful and have a breath of natural fragrance, also have the functions such as certain antibacterial, health care simultaneously, natural dyestuff stems from nature simultaneously, be harmful to human health, good, free from environmental pollution, biodegradable with Environmental compatibility, give people's physiology and psychological comfort, be therefore deeply subject to people's favor.
Along with people constantly deepen the understanding of Chemicals, chemical dyestuff, European Union (REACH), the U.S. etc. constantly release unauthorized substances, and China also pays much attention to.Chemical dyestuff is a major source of pollutant of China, and the health of human body has also been brought to certain harm.From animals and plants, extracting the renewable material of dying becomes a kind of first-selected.This dyestuff neither works the mischief to environment, also can not produce any side effect to human body.
Chinese fan palm, cry again flabellum certain herbaceous plants with big flowers, certain herbaceous plants with big flowers tree, latin name Livistona chinensis, belong to Palmae, Livistona, happiness high temperature and humidity, cold-resistant resistance to the moon, its main adolescence is that early March is to late May, to late October, contain phenols, reducing sugar, tannin triglyceride and various Amino Acid Composition secondary mid-September adolescence in Chinese fanpalm seed, have a large amount of cultivating and growings in Xinhui of Guangdong Province.
Summary of the invention
An object of the present invention is the technical problem that will solve for above, vegetable dye a kind of environmental protection, high fastness is provided.
Another object of the present invention is to provide a kind of method of preparing described vegetable dye.
A further object of the present invention is to provide a kind of method that uses described vegetable dye to dye.
For reaching above object, the invention provides a kind of vegetable dye, the ethanol extraction that it contains Chinese fanpalm seed.
The present invention also provides a kind of method of preparing described vegetable dye, it is characterized in that comprising the following steps:
(1) clean Chinese fanpalm seed, pulverizing;
(2) with alcohol, Chinese fanpalm seed is extracted;
(3) distillation, recovered alcohol;
(4) filter, obtain dyestuff.
Preferably, the concentration of described alcohol is 95%.
Preferably, the part by weight of described Chinese fanpalm seed and described alcohol is 4:1.If ratio is very few, extract incomplete.If excessive, cause waste, increase extraction cost.
Preferably, in described step (2), with alcohol-pickled described Chinese fanpalm seed at least 48 hours.Time is too short, and bubble is got not exclusively, and utilization ratio is low.Overlong time, other chemical goods and materials immersed go out, affect purity and the coloured light of color.
Preferably, in described step (4), adopt 100 object filtering nets to filter.
The present invention also provides the described vegetable dye of application to dye to fabric and/or non-woven.
Preferably, described fabric is cotton fabric, linen, rayon, real silk fabric.
Preferably,,, under 60 DEG C of conditions, dye with described vegetable dye after fabric grafting by cation graft agents.
Preferably, with described vegetable dye, real silk fabric is carried out to substantive dyeing.
Preferably, described vegetable dye consumption is that fabric is weighed to 2%.
Compared with prior art, vegetable dye provided by the invention is owing to containing Polyphenols coloring matter, by hydrophobic bond and multiple spot hydrogen bond and protein generation association reaction, because the ortho position phenolic hydroxyl group of the phenolic hydroxyl group in polyphenol has the stronger short ability of catching to free radicals such as active oxygens, make plant polyphenol have very strong oxidation-resistance and the ability of removing free radical, also have in addition the ability of stronger attraction UV-light.Therefore use vegetable dye of the present invention to fabric, especially real silk, dyes, and fastness is high, the soft elegance of tone, natural environmental-protective.
