Abstract
The invention relates to a dyeing method of natural dye material of cotton fabric, which belongs to the field of fabric dyeing and finishing technique and comprises: processing the modifying liquid byuse of the modifying agent containing anode ions group, firstly modifying the cotton fabric and dyeing the fabric with the natural dyeing material, after cleaning, fulfilling the dyeing with the natu ral dye material of cotton fabric, wherein due to the modifying process on the cotton fabric in advance, the anode ion base is introduced into the cotton fabric to strengthen the combination ability from the cotton fabric to the natural dye material of cathode ion, which effectively improves the cotton fabric dyeing rate, color depth and dyeing evenness and distinctly improves the anti-washing andanti-abrasion firmness of the dyed cotton fabric. The process has simple operation, even dyeing and wide application prospect.
Description
Technical field: the present invention relates to the natural dye dying technology of cotton fiber, belong to the textile dyeing and finishing technical field, particularly the modification liquid and preparation method thereof of cotton fiber and in the application of natural dye dying technical elements.
Background technology
Cotton fiber is a kind of important natural fabric, with advantages such as its snugness of fit, recyclability and biodegradables and enjoy people's favor.Natural dye comes from nature, and is harmless to health, and good with Environmental compatibility, do not pollute the environment, and be biodegradable, meet modern people requirement healthy and that environmental protection is paid attention to self.Thereby the ecological dyeing technology of application natural dye meets modern environmental and ecological idea.
Natural dye has higher dye-uptake and COLOR FASTNESS mostly on protein fibres such as silk, wool, and the dye-uptake on cellulose fibres such as cotton, fiber crops is low, COLOR FASTNESS is also very poor, need handle with mordant and just can reach higher dye-uptake and COLOR FASTNESS, but traditional natural dye mordant is heavy metallic salt mostly, and is unfavorable to environment.Relatively the structure of cellulose fibre and protein fibre as can be known, protein fibre contains a lot of amino and the stronger group of carboxyl isoreactivity, wherein the amino on the protein fibre is positively charged in dye liquor, make negatively charged natural dye be easy to absorption and on dye, so natural dye has dye-uptake and dyefastness preferably on protein fibre.Reactive group has only hydroxyl in the cellulose fibre, and kind is single, has lacked the positive electric group of similar amino class.Therefore, less at the affinity between natural dye and the cotton fiber, the weakness that the active group kind is single and respond is not strong on the cotton fiber, trial is carried out chemical modification to cotton fiber, make its surface have cationic, to strengthen the binding ability of cotton fiber and natural dye, improve dye-uptake and the COLOR FASTNESS of natural dye on COTTON FABRIC.
Summary of the invention
It is low to the objective of the invention is to overcome natural dye dye-uptake on cotton fiber, and the shortcoming of COLOR FASTNESS difference provides a kind of natural dye dying method based on cotton fiber modification.
For achieving the above object, the technical solution used in the present invention is: a kind of natural dye dying method based on cotton fiber modification is provided, it is characterized in that treatment process steps is as follows: a kind of natural dye dying method based on cotton fiber modification is characterized in that treatment process steps is as follows:
(1) with containing the modifier of cation group and the modification liquid that caustic soda is prepared into, cotton fiber is carried out modification handle, wherein, cation modifier consumption 15～25 grams per liters, caustic soda consumption 2～8 grams per liters, modification treatment temperature are 60～80 ℃, and the time is 30～60 minutes;
(2) under the room temperature condition, earlier COTTON FABRIC was handled 10 minutes in 15～25 grams per liter cation modifiers, be warming up to 60～80 ℃ with 1～2 ℃/minute programming rate again, gradation adds 2～8 grams per liter caustic soda, continues processing 30～60 minutes;
(3) with the COTTON FABRIC after the modification at ambient temperature prior to dyeing in the natural dye dye liquor 5～20 minutes, be warming up to 70～98 ℃ with 1～2 ℃/minute programming rate again, continue dyeing 30～90 minutes;
(4) finish the natural dye dying of cotton fiber after the washing.
Described cation modifier contains cation group, as contains the amine or the quaternary ammonium compound of epoxide group, n-methylolacrylamide compound, nitrogen-containing heterocycle compound, amino polymer etc.
The concentration of described natural dye dye liquor is X% (o.w.f) (X decides according to the fabric color depth and dyestuff performance), be that every gram fabric needs 0.0X gram dyestuff; bath raio (promptly refer to cloth heavy amount: the dye liquor quality)=1: 5～1: 40,70～98 ℃ of dyeing temperatures, dyeing time 30～90 minutes.
Described natural dye is X% with respect to the weight percent concentration of fabric, is according to the fabric color depth and dyestuff performance and decide.
Describedly contain the modifier of cation group and the application in the cotton fiber natural dye dying is handled of modification liquid that caustic soda is prepared into.
Compared with prior art, the present invention has the following advantages:
(1) cation modifier of the present invention's use can react with cotton fiber under alkali condition, on cotton fiber, introduce positive charge, therefore strengthened the adsorption capacity of cotton fiber, effectively raised the dye-uptake of natural dye on cotton fiber anionic natural dye.
(2) the present invention has overcome and dyes cotton fiber on traditional natural dye and need to meet the requirement of green dyeing and finishing technique by the mordant shortcoming.
(3) through after the modification, not only improved the uniformity that natural dye dyes on COTTON FABRIC, and given good fastness to washing of dyed cotton fabric and fastness to rubbing.
(4) the natural dye dying technology based on cotton fiber modification of the present invention, even dyeing, technology is simple, and is easy to operate, especially can use dyeing machine to produce on a large scale, has broad application prospects.
