Abstract

The invention discloses a dyeing method using crude salt as an activated dye accelerating agent. The method comprises the steps: preparing a dye liquid from 1-2g/L of hydroxypropyl methyl cellulose, 1-2g/L of aliphatic amine polyoxyethylene ether, 1-2g/L of ethylene diamine tetraacetic acid, 1-2g/L of ortho-hydroxybenzoic acid, 1-2g/L of sodium polyacrylate, 1-2g/L of hydrolytic polymaleic anhydride, 1-2g/L of maleic acid-acrylic copolymer, 1-2g/L of a crylic acid-2-acrylamide-2-methyl propanesulfonic acid multipolymer, 130g/L crude salt and 15g/L of dyeing auxiliaries; mixing fabrics with the dye liquid, dyeing with a bath ratio of 3:25; heating at the speed of 5 DEG C/minute to be 95 DEG C; adding 25g/L of sodium carbonate for fixing color and carrying out heat preservation for 2 hours; and washing, soaping, washing and drying. According to the method, the problem that the cost caused by using industrial salt or industrial anhydrous sodium sulphate as the accelerating agent is high when a conventional activated dye is used for the dyeing is solved, and the defect of the dyeing caused by using the crude salt as the accelerating agent and the defect of low coloring of the fabrics are avoided; moreover, the quality of a prepared product is the same as that of a product prepared by using a conventional process.

Description

Colouring method with crude salt as REACTIVE DYES accelerant

Technical field

The present invention relates to the colouring method as REACTIVE DYES accelerant with crude salt.

Background technology

During reactive dyestuffs in exhaustion dyeing, owing to there is certain charge repulsion between dyestuff and fiber, need add a large amount of neutral electrolytes as accelerant, promote the absorption of dyestuff on fiber.And in actual production process, generally use industrial table salt or industrial glauber salt as accelerant, but its price is higher, has brought certain burden to the production cost of printing and dyeing mill.And crude salt to be salt solution in seawater or salt well, salt pond, brine spring shine through decocting the crystallization forming, mineral salt, is crude macrogranule salt, main component is sodium chloride, price is far below industrial table salt and industrial glauber salt; But in crude salt, contain the impurity such as calcium, magnesium, iron, zinc, copper, during dyeing, 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 DYED FABRICS Dry Sack is lower for above-mentioned metal ion.

Summary of the invention

The object of the present invention is to provide a kind of crude salt of using as the colouring method of REACTIVE DYES accelerant, the higher problem of cost of having brought as accelerant with industrial table salt or industrial glauber salt when it had both solved conventional reactive dyeing, the dyeing defect having brought while having avoided again crude salt to dye as accelerant and the lower shortcoming of fabric colouring, the product quality making is consistent with common process.

For achieving the above object, technical scheme of the present invention is to design a kind of crude salt of using as the colouring method of REACTIVE DYES accelerant, comprises the steps:

Get 1～2g/L hydroxypropyl methylcellulose, 1～2g/L aliphatic amine polyoxyethylene ether, 1～2g/L disodium ethylene diamine tetraacetate, 1～2g/L salicylic acid, 1～2g/L Sodium Polyacrylate, 1～2g/L hydrolytic polymaleic anhydride, 1～2g/L maleic acid-acrylic acid copolymer, 1～2g/L acrylic acid-2-acrylamide-2-methyl propane sulfonic multiple copolymer, 130g/L crude salt, 15g/L dyeing assistant, prepare dye liquor;

Fabric is dropped in dye liquor, dye bath ratio is 3:25, then with 5 ℃/min, is warming up to 95 ℃ again, adds 25g/L sodium carbonate fixation, is incubated 2 hours, then washes, soaps, washes, dries.

Advantage of the present invention and beneficial effect are: provide a kind of crude salt of using as the colouring method of REACTIVE DYES accelerant, the higher problem of cost of having brought as accelerant with industrial table salt or industrial glauber salt when it had both solved conventional reactive dyeing, the dyeing defect having brought while having avoided again crude salt to dye as accelerant and the lower shortcoming of fabric colouring, the product quality making is consistent with common process.
