Abstract
The invention provides a method for dyeing a modified cellulose fiber textile by a rhubarb and turmeric dye. The method comprises the following: 1. a step of modifying a quaternary ammonium group of the cellulose fiber textile, in which a modifying agent with a concentration of 50 to 60 g/l and sodium hydrate with a concentration of 12 to 18g/l react for 40 to 60 minutes at a temperature of between 64 and 75 DEG C, the bath ratio is 1:30; in the post treatment after the modification, the fiber textile is washed by hot water at a temperature of between 40 and 50 DEG C for 10 minutes, is washed by cold water, is prickled by HAC with a concentration of 2 to 3g/l for 2 minutes, is washed by water to be neutral and is dried; 2. a step of preparing the dye solution by the sodium hydrate extracting agent with a concentration of 15 to 45g/l; and 3. a step in which the modified cellulose fiber textile is dyed, washed by water and dried directly by the dyeing technique and is washed by soap, washed by water and dried. The technique is simple and easy to implement, does not need the mordanting and the fixation processes and the like, has high rate of dye-uptake, good dye quality and the friction resisting color fastness and the colorfastness to washing up to more than three grades, is nontoxic, does not pollute the environment, and has low cost, and remarkable economic benefits and environmental benefits.
Description
Technical field
The invention belongs to textile dyeing and finishing technical field, particularly natural plant dye and be used for the staining technique field of cellulose base fiber fabric.
Background technology
Rise today of environmental protection trend in the whole world, weaving and clothes tend to naturalization, and people's yearning goes back to nature.Be subjected to the influence of the dress ornament trend of " returning Piao returns very " and " back to nature ", the utilization of natural dye and suitability for industrialized production become focus again.Natural dye comes from nature, and is harmless to health, and good, free from environmental pollution with Environmental compatibility, and dye liquor is biodegradable.Adopt natural dye dying: cellulose base fiber fabric color and luster nature, graceful, the unique uniqueness of tone, be difficult for reappearing, cater to people's pursuing individualityization, diversified requirement, also can give fabric some specific function simultaneously, as: health cares such as antibiotic, anti-inflammatory.Not only can beautify people's life, give on people's physiology and psychological comfort, also help environmental protection.Along with the raising of people's living standard, environmental protection and health are more and more paid attention to.Natural dye dying enjoys people's favor.China's vegetable colour aboundresources, the history that has long vegetable colour to dye as long as reasonable development then not only can obtain considerable social benefit and economic benefit, be the more important thing is and can be kept ecological balance, and improves the ecological environment.
Turmeric and rheum officinale are a kind of traditional natural dyes.Its main component of turmeric is yellow curcumin, demethoxycurcumin and bisdemethoxycurcumin.The main chemical compositions of rheum officinale is a rhatannin, can decompose to produce glucogallic acid, and it is the glycocide with ester-formin, and the hydroxy-anthraquione derivative.These two kinds of dyestuffs are dyestuffs the most representative in the natural plant dye.
Turmeric is a medicinal material as medicine-food two-purpose at Chinese prescription, has broken blood promoting the circulation of qi, effect such as inducing meastruation to relieve menalgia, also has anti-inflammatory in addition, suppresses bacterium and especially hay bacillus, staphylococcus aureus and Escherichia coli are had the good restraining effect.The fabric of rheum officinale dyeing has good ultraviolet resistance.Therefore the fabric with natural dye dying also has certain function of health care to human body.
Cellulose fibre occupies an important position in textile industry, accounts for 65% of whole world fiber total amount.Cellulose fibre is comfortable naturally, is the garment material that people like.Natural fibre products dyes with natural plant dye, has realized the pure naturalization of garment material, with the fibre that dyes on rheum officinale, the turmeric dyestuff human body is also had certain function of health care, has improved value-added content of product.Meeting the requirement of new century people to clothes, is an excellent research approach of exploitation " ecological clothes " and " complete green clothes " textiles.But mainly concentrate on the natural protein fibre to the natural plant dye Research on Dyeing at present, mainly be because natural fabric is a pole filter, and natural plant dye is nonpolar, adhesion is very little each other, affinity is relatively poor, dyestuff is low to the fixation rate and the dye-uptake of fabric, it is not bright-coloured to dye the back fabric color, and dyefastness is low.But handle by cellulose fibre being carried out modification, cellulosic ionic by cloudy lotus sex reversal Chengyang lotus property; Making has certain affinity between natural fabric and the dyestuff, just can obviously improve the fixation rate and the dye-uptake of dyestuff.As the patent No. is that 200710032110.6 Chinese patent is disclosed: based on the natural dye dying method of cotton fiber modification, only limitation is used aspect the modification and dyeing of cotton fiber.Therefore the natural fabric staining technique that extensively is applied to natural dye efficiently becomes the focus of research and development again.

Summary of the invention
At the deficiency that above-mentioned prior art exists, the purpose of this invention is to provide that a kind of technology is simple, dye-uptake is high, dyeing quality is good, dyes the method for modified cellulose fibre fabric on the natural dye of non-environmental-pollution.
Technical scheme of the present invention is: at first use quaternary ammonium salt cationic modifier, cellulose base fiber fabric is carried out the quaternary ammonium group modification, with cellulosic ionic by cloudy lotus sex reversal Chengyang lotus property; Produce the extract of rheum officinale and turmeric dyestuff then, the modified cellulose fibre fabric is dyeed with direct dyeing technology.
Dyeing mechanism is: the ionization in the aqueous solution of the hydroxyl of dyestuff, generate negative oxygen ion, and can dye seat with the quaternary ammonium group CATION of modified cellulose fibre fabric and combine with ionic bond; In addition, dyestuff also can combine with Van der Waals force and hydrogen bond with cellulosic molecule.Increase the washable and crocking resistance of final products with this, improve the COLOR FASTNESS of product.
Technical scheme of the present invention is divided into following steps:
1. the modified technique of cellulose base fiber fabric
The modification of cellulose base fiber fabric: with cellulose base fiber fabric by 1: 30 bath raio (cloth quality: the modified solution quality) put into by modifier (50～60g/l) and NaOH (in 12～18g/l) the formulated modified solutions, at room temperature the programming rate with 2 ℃/min is warmed up to 65～75 ℃, reaction 40～60min;
Modification post processing: the cellulose base fiber fabric hot water wash after the modification: wash 10min → cold wash → pickling for 40～50 ℃: HAC 2～3g/l washes 2min → be washed to neutrality → oven dry.
Wherein said modifier is: contain any in the chloropharin base cationic compound, as: 3-chloro-2-hydroxyl trimethyl ammonium sulfate or 3-chloro-2-hydroxyl trimethyl ammonium chloride.
2. rheum officinale, turmeric dyestuff extraction process
Extractant: concentration is the NaOH aqueous solution of 15～45g/l
Big yellow dye extraction process: big yellow dye concentration 90～110g/l, NaOH concentration 35～45g/l, under 75～85 ℃ of temperature, extraction 40～50min, re-extract 3 times is removed filter residue with filtration method, and it is standby to merge three big yellow dye extracts.
