Abstract
The invention discloses a surface treatment and low-temperature dyeing method for wool. The method comprises the following steps of: treating the surface of wool by using a binary solvent consisting of an ionic liquid and water at the room temperature; washing with water; and dyeing at the temperature 65-85 DEG C. In the method disclosed by the invention, wool is treated at the room temperature, and the ionic liquid in the treating solvent can be used circularly; and the method has the advantages of high leveling property, high fabric strength keeping rate, low dyeing temperature, and the like.
Description
Technical field
The present invention relates to a kind of wool processing method, relate in particular to a kind of wool surface treatment, low-temperature dyeing method.
Background technology
The traditional high-temp dyeing of wool is not only consumed energy greatly, and makes wool at high temperature suffer the effect of chemical reagent and heat, causes the wool yellowing, influences fiber outward appearance and physical and mechanical properties greatly, destroys the good natural quality of wool.
Current have villaumite oxidation pre-treatment method, formic acid method for pretreating, biology enzyme method for pretreating etc. about the low temperature dyeing of wool method both at home and abroad.No matter be DCCNa (DCCA) in the villaumite oxidation pre-treatment method, or clorox, in use all can produce AOX, environment is caused-fixed pollution; Excessive in the formic acid method for pretreating because of the formic acid consumption, equipment is had big corrosiveness, and in can only dying, light color, and cause uneven dyeing easily, be difficult to promote; The concentration of enzyme and vigor receive more multifactor influence during the biology enzyme method for pretreating, and too much enzyme preparation is drawn in the human body, can produce bigger adverse effect to human body.In a word, the above-mentioned method that is used for low temperature dyeing of wool all fails to obtain industrial applications.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of wool surface treatment, low-temperature dyeing method, it is characterized in that: the binary solvent of at room temperature forming with ionic liquid and water is handled the wool surface, washing, dyeing temperature is 65-85 ℃.
As an optimal technical scheme of the present invention, wherein the mass ratio of ionic liquid and water is 95:5-5:95.
As another optimal technical scheme of the present invention, wherein said ionic liquid is the butyl imidazole villaumite, and after surface treatment, reclaims ionic liquid.
As another technical scheme of the present invention, wherein the surface-treated time is 0.1-168h.
Dyeing prescription of the present invention is according to the conventional dyeing technique prescription that boils in this area, and only the dyeing temperature ratio dyeing technique that boils is lower.Certainly the present invention also can adopt the dyeing recipe technological parameter of REACTIVE DYES, and concrete parameter is following:
REACTIVE DYES (%) are 0.5-2 (o.w.f);
Levelling agent paregal O (g/L) 1;
Salt (g/L) 30;
Dyeing temperature (℃) 65-85;
pH 4-5；
Bath raio 1:30-100;
Dyeing temperature retention time (min) 40-80;
Heating rate (℃/min) 0.5-3.
As an optimal technical scheme of the present invention, can be warming up to 75-85 ℃ of insulation dyeing, preferred 80-85 ℃; The insulation dyeing time is preferably 40-80min, more preferably 45-65min; Programming rate is preferably 0.5-2.5 ℃/min, more selects 0.5-1.5 ℃/min.
The all raw material that uses among the present invention is conventional materials used, can buy from market.
All amounts and percentage among the present invention except as otherwise noted, are weight and percentage by weight.
Method of the present invention is at room temperature handled wool, and the ionic liquid of handling in the solvent can recycle, and has advantages such as good level-dyeing property, the fabric strength conservation rate is high, dyeing temperature is low.
