Abstract
The invention discloses a dyeing method taking coarse salt as a reactive dye accelerating agent. The cellulose fiber, protein fiber or chinlon is dyed by reactive dye through dip dyeing technique, the dyeing technique comprises the following steps of: dissolving the reactive dye, the dye accelerating agent and a dyeing auxiliary into water to prepare dye solution, wherein the dye accelerating agent is coarse salt, the concentration of the reaction dye is 0.05-10%owf, the concentration of the coarse salt is 10-120g/L, the concentration of the dyeing auxiliary is 2-5g/L; then adding texture into the dye solution, wherein the dyebath ratio is 1:(10-100); then increasing the temperature to 40-90 DEG C at the temperature increase speed of 0.5-2 DEG C/min, adding 1-20g/L sodium carbonate for fixing the color, preserving heat for 20-90min, then washing, soaping, washing and drying after preserving heat. According to the dyeing method, the coarse salt is used for replacing the neutral electrolyte in the traditional technique as a dye accelerating agent for the reaction dye, and the dyeing effect consistent with that of the traditional technique can be achieved only by adding 2-5g/L of compound auxiliary.
Description
Technical field
The invention belongs to the dyeing and finishing technique field, relate to a kind of crude salt that uses as the colouring method of REACTIVE DYES accelerant, especially can realize the extensive adaptability of REACTIVE DYES, reduce production costs.
Background technology
The REACTIVE DYES chromatogram is complete, the relative reducing dye of dye process is simple, and dyefastness satisfies to take and requires and become the main dye species that cellulose fibre, protein fibre and nylon dyeing are used.
During reactive dyestuffs in exhaustion dyeing, owing to having certain charge repulsion between dyestuff and the fiber, need to add a large amount of neutral electrolytes (as: sodium chloride, sodium sulphate etc.) as accelerant, promote the absorption of dyestuff on fiber.And in the actual production process normal operation industrial table salt or industrial glauber salt as accelerant, the purity of industrial table salt and industrial glauber salt is higher, can greatly improve the absorption of REACTIVE DYES on fiber, but its price is higher, has brought certain burden for the production cost of printing and dyeing mill.And crude salt to be salt solution in seawater or salt well, salt pond, the brine spring shine the crystallization that forms through frying in shallow oil, namely mineral salt is crude macrogranule salt, main component is sodium chloride, price is far below industrial table salt and industrial glauber salt; But contain the impurity such as calcium, magnesium, iron, zinc, copper in the crude salt, during dyeing above-mentioned metal ion easily and dyestuff generation complexing, therefore directly easily cause the defects such as look flower, color dot as reactive dyeing accelerant with crude salt, and the DYED FABRICS Dry Sack is lower.
Summary of the invention
Adding industrial table salt or industrial glauber salt cost are higher when the object of the invention is to for reactive dyeing, easily cause the defects such as look flower, color dot and add when crude salt dyes, and the lower shortcoming of DYED FABRICS Dry Sack, and a kind of new dyeing prescription is provided.This method is utilized in dyeing system and is added by phytic acid, sodium phytate, sodium metasilicate, disodium ethylene diamine tetraacetate, tertiary sodium phosphate, Sodium Polyacrylate, hydrolytic polymaleic anhydride, maleic acid-acrylic acid copolymer, acrylic acid-2-acrylamide-2-methyl propane sulfonic multiple copolymer, 2-phosphonic acid butane-1,2, the dyeing assistant of one or more compositions of mixtures in the 4-tricarboxylic acids etc., the higher problem of cost of having brought as accelerant with industrial table salt or industrial glauber salt when both having solved conventional reactive dyeing, the dyeing defect that has brought when having avoided again crude salt to dye as accelerant and the lower shortcoming of fabric colouring, the product quality that makes is consistent with common process.
The present invention adopts following technical scheme: with the colouring method of crude salt as REACTIVE DYES accelerant, adopt exhaust process with REACTIVE DYES to cellulose fibre, protein fibre or nylon dyeing, dye process is with REACTIVE DYES, accelerant and the dyeing assistant dye liquor that is mixed with soluble in water, described accelerant is crude salt, described dyeing assistant is phytic acid, sodium phytate, sodium metasilicate, disodium ethylene diamine tetraacetate, tertiary sodium phosphate, Sodium Polyacrylate, hydrolytic polymaleic anhydride, maleic acid-acrylic acid copolymer, acrylic acid-2-acrylamide-2-methyl propane sulfonic multiple copolymer, 2-phosphonic acid butane-1,2, at least a in the 4-tricarboxylic acids, the concentration of described REACTIVE DYES is 0.05～10%owf, described crude salt concentration is 10～120g/L, described dyeing assistant is 2～5g/L, again fabric is dropped in the dye liquor, dye bath ratio is 1:10～100, then the programming rate with 0.5～2 ℃/min is warming up to 40～90 ℃, add 1～20g/L sodium carbonate fixation, and be incubated 20～90min, be incubated after washing, soap, washing, oven dry.
The concentration of described REACTIVE DYES is preferably 0.1～5 %owf.
The concentration of described crude salt is preferably 50～80 g/L.
During dyeing described REACTIVE DYES is had no special requirements.
The invention has the beneficial effects as follows: the neutral electrolyte (as: sodium chloride, sodium sulphate etc.) in the employing crude salt replacement traditional handicraft is as the accelerant of reactive dyeing, and a compound auxiliary that only needs to add 2～5g/L can reach the Color consistent with traditional handicraft.Adopt crude salt as the accelerant of reactive dyeing, the higher problem of cost of having brought as accelerant with industrial table salt or industrial glauber salt when both having solved conventional reactive dyeing, the dyeing defect that has brought when having avoided again crude salt to dye as accelerant and the lower shortcoming of fabric colouring, the product quality that makes is consistent with common process.Technical scheme technique of the present invention is simple, convenient operation, without specific (special) requirements, utilizes normal dyeing equipment just can carry out large-scale production to REACTIVE DYES and equipment, has broad application prospects.
