Description
Technical field
The invention belongs to dyeing fabric technical fields, and in particular to a kind of organic solvent colouring method of full wool fabric.
Background technique
Reactive dyeing mechanism is fiber to the nucleophilic displacement of fluorine or addition reaction between dye activity group, in traditional water
In phase vital staining, hydrone has stronger nucleophilic reactivity, equally necleophilic reaction can occur with reactive dye, generate hydrolysis and live
Property dyestuff, the hydrolysed reactive dye cannot react with fiber again.The reactive dyeing of fabric can generate in traditional mode of production
A large amount of waste water contains certain density heavy metallic salt dyeing auxiliaries in waste water, therefore the processing difficulty of waste water is big.It is useless in order to reduce
The generation of water, the innovation in cleaning process include in the process of cleaning using ultrasound, or using three high temperature washing substitution five
Road standard wash.But the above method cannot thoroughly solve the problems, such as reactive dye cleaning water content consumption it is big.
Improved technical solution is dyed using organic solvent, and in organic solvent, dye molecule will not hydrolyze.Tradition
Organic solvent system dye used by organic solvent be there are the organic solvents such as more highly polar alcohol, ether as water, but
It is Swelling Capacity deficiency of the solvent for cellulose fibre of even numbers, in order to destroy the phase interaction of hydrogen bond between cellulose fibre
With, it is also necessary to more or less uses water or other nucleophilic solvents as sweller；And.In order to realize and traditional catalyst
Dyestuff identical dyefastness must post-process the removal wool surfaces not fixed dye of chemistry by alkalinity after reactive dyeing
Material, but the method for this alkalinity post-processing can damage wool fiber.

S2: beta-sulfuric ester vinyl sulfone dyestuff is dissolved in 50 mL deionized waters, adjusts pH value to 8.5~9, mechanical stirring adds
Heat is added acidic pH adjustor and is adjusted to neutrality the pH value of reaction solution, distill to 60~70 DEG C and 2~3h of insulation reaction
Obtain vinyl sulfone dyestuff；
S3: vinyl sulfone dyestuff obtained by S2 is dissolved in the organic solvent mixed by dimethyl sulfoxide and citrate, by S1
The full wool fabric of gained is placed in the dye liquor being configured to, bath raio 1:(20~30), heated sealed to 70~80 DEG C of 3~5h of reaction,
Cooling, removes the organic solvent in full wool fabric；
S4: the pyridine solution boiling that full wool fabric obtained by S3 is placed in 25% is boiled three times, each 15~20min of duration, then soap
Washing is washed down, the full wool fabric dyed.
Preferred technical solution is, in S2 the molar concentration of beta-sulfuric ester vinyl sulfone dyestuff in deionized water be 20~
30mol/L。
Preferred technical solution is that the w/v of vinyl sulfone dyestuff in organic solvent is 30~80g/L, You Jirong
