The invention discloses a kind of low temperature dyeing of wool method, except that adding conventional dyestuff and auxiliary agent, also add reductant in dye bath, be warming up to 70-85 ℃ then, add oxidant insulation dyeing again, the ratio of reductant and oxidant is 1: 3.Redox system low temperature dyeing of wool method of the present invention is different with the low-temperature dyeing method of prior art, this low-temperature dyeing method and technology are to add reductant and oxidant in dye bath, consumption is few, with low cost, do not need that pollutant pre-treatment and other adding assistant are had advantages such as dyeing rate is fast, good level-dyeing property, dye bath exhaustion rate height, dyeing time is short, dyeing temperature is low.The present invention can be used for ACID DYES, REACTIVE DYES is woolen dyed.
Description
One, technical field
The present invention relates to a kind of low temperature dyeing of wool method, relate more particularly to a kind of low temperature dyeing of wool method that when woolen dyed, adds reductant and oxidant.
Two, background technology
Traditional woolen dyed need are finished through the dyeing technique that boils for a long time, cause wool fabric damage, yellowing easily, have a strong impact on quality, feel and the vividness of dyeing product, and the while is the demand of incompatibility energy savings also.
Current have formic acid method, organic solvent method, interpolation surfactant method and low-temperature plasma facture etc. about the low temperature dyeing of wool method both at home and abroad.The special equipment that the formic acid method necessarily requires to use expensive acid-resistant steel material to make; Organic solvent method requires to reclaim organic solvent, and very high to the sealing requirements of equipment, and the superperformance of dyeing is also had a strong impact on; Add surfactant method and rare-earths dyeing method etc. and all dyestuff is had certain requirement, and require dye bath acidity high, increase corrosion, worsen ecological environment equipment; Low-temperature plasma facture cost height, complex process and effect are undesirable.In a word, the above-mentioned method that is used for low temperature dyeing of wool all fails to obtain industrial applications.
Three, summary of the invention
The purpose of this invention is to provide a kind ofly have that dyeing rate is fast, good level-dyeing property, dye bath exhaustion rate height, dyeing time is short and dyeing temperature is low low temperature dyeing of wool method.
This and other purpose of the present invention will further embody and set forth by following detailed description and explanation.
In low temperature dyeing of wool method of the present invention, in dye bath, except that adding conventional dyestuff and auxiliary agent, also add reductant, be warming up to 70-85 ℃ then, add oxidant insulation dyeing again, the ratio of reductant and oxidant is 1: 3.
Further, in low temperature dyeing of wool method of the present invention, the programming rate behind the adding reductant is 0.5 ℃/minute, is warming up to 75-85 ℃, adds oxidant insulation dyeing 50-70 minute again.Be preferably, the programming rate behind the adding reductant is 0.5 ℃/minute, is warming up to 80-85 ℃, adds oxidant insulation dyeing 55-65 minute again.
In low temperature dyeing of wool method of the present invention, described reductant is a thiocarbamide, and the content in dye bath is the 0.01-0.05 mole; Described oxidant is a hydrogen peroxide, and the content in dye bath is the 0.03-0.15 mole.
Redox system low temperature dyeing of wool method of the present invention is different with the low-temperature dyeing method of prior art, this low-temperature dyeing method and technology are to add reductant and oxidant in dye bath, consumption is few, with low cost, do not need that pollutant pre-treatment and other adding assistant are had advantages such as dyeing rate is fast, good level-dyeing property, dye bath exhaustion rate height, dyeing time is short, dyeing temperature is low.The present invention can be used for ACID DYES, REACTIVE DYES is woolen dyed.
According to above-mentioned feature, the dyeing recipe that the present invention is applied to ACID DYES is:
Dyestuff (%) is 0.5-3 (o.w.f)
Glauber salt (%) is 5-15 (o.w.f)
Bleeding agent SP-2 (g/l) 1.5
Thiocarbamide (mol/l) X
Hydrogen peroxide (mol/l) Y
Temperature (℃) 70-85
Bath raio 1: 30-100
Dyeing temperature retention time (min) 40-60
Hydrogen peroxide wherein: thiocarbamide=3: 1, concentration is chosen as 0.15M: 0.05M, 0.075M: 0.025M or 0.03M: 0.01M etc.
Four, description of drawings
Fig. 1 is the dyeing heating curve of the inventive method.
The all raw material of Shi Yonging etc. all is conventional uses in the present invention, can buy from market.In the present invention, refer in particular to as non-, all amount, percentages are unit of weight.
Below in conjunction with embodiment the present invention is carried out concrete description.As known by the technical knowledge, the present invention can realize by other the embodiment that does not break away from its spiritual essence or essential feature.Therefore, following embodiment with regard to each side, all just illustrates, and is not only.All within the scope of the present invention or the change that is equal in the scope of the present invention all be included in the invention.
