Description
Technical Field
The invention relates to the field of dyeing and finishing soaping processes, in particular to an anti-staining low-temperature soaping agent for an active dye and a soaping method.
Background
Reactive dyes are generally used for dyeing or printing fibers (such as cellulose fibers, protein fibers, nylon fibers and the like), yarns or fabrics containing hydroxyl, amino or imino groups, because the reactive dyes have the characteristics of bright color, good leveling property, simple and convenient dyeing, complete color spectrum, low cost and the like, and the reactive dyes are reactive dyes, and reactive groups contained in molecules of the reactive dyes can react with the hydroxyl, amino or imino groups in the fibers (such as nucleophilic substitution or nucleophilic addition reaction) to generate firm covalent bonds in the dyeing process, so that the reactive dyes have high dyeing fastness. However, the dye can not completely react with the fiber during printing or dyeing, the utilization rate is about 70%, some unreacted dye and hydrolytic dye can exist on the fiber or fabric, and the unreacted dye must be soaped and removed, otherwise the color fastness (mainly water washing color fastness and rubbing color fastness) of the dyed fiber or fabric is seriously affected, or when reactive dye is used for printing or dyeing multicolor fabric, the unreacted dye can continue to react and dye with light-colored fabric or white-bottom fabric, so that staining is caused, and the white-bottom color and the color fastness are affected, therefore, the soaping agent plays an important role in the color fastness of the fabric and the printing white-bottom effect.
The soaping agent is one of the most commonly used auxiliary agents in the printing and dyeing industry and plays a role in removing the fixed dye on the fiber. The traditional soaping process is to carry out multiple soaping and water washing at 95-105 ℃ so as to meet the color fastness requirement of customers on fabrics, the energy consumption and the water consumption are extremely high, and the national environmental protection has increasingly strict requirements and regulations on the discharge amount of wastewater, COD (chemical oxygen demand), chromaticity and total nitrogen of ammonia nitrogen of printing and dyeing enterprises.
The soaping agent on the market is mainly a surfactant or a compound thereof, and the soaping agent has high foam, poor floating color removing capability, high energy consumption and large wastewater discharge amount and needs high temperature and repeated washing; in addition, the soaping agent has poor anti-staining capability, so that the white bottom can not meet the requirement of anti-staining when the printed cloth is soaped. The chroma of the soaping wastewater of dyeing and printing by the reactive dye is particularly high; because various auxiliary agents are used, the COD of the wastewater is also high; particularly, urea is often used as a humectant in a large amount in the printing process, and the control of the total nitrogen content in the wastewater is also a problem.
Disclosure of Invention
The invention aims to provide a reactive dye anti-staining low-temperature soaping agent, which is applied to a soaping process after printing or dyeing of reactive dyes on fabrics or fibers, and aims to solve the problems that the prior soaping agent has poor anti-staining effect, low soaping efficiency, too much water consumption, high soaping temperature, too high energy consumption, too high chroma of soaping residual liquid, too high COD (chemical oxygen demand) and high total nitrogen in the soaping process, and the specific scheme of the invention is as follows:
the low-temperature soaping agent comprises the following components in percentage by mass:
further, the alkaline substance is selected from one or more of sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, potassium carbonate, sodium phosphate, sodium silicate, sodium metasilicate pentahydrate, or anhydrous sodium metasilicate.
Further, the inorganic salt is selected from one or more of sodium chloride, potassium chloride, ammonium chloride, sodium sulfate, potassium sulfate, or ammonium sulfate.
Further, the chelating dispersant is selected from one or more of sodium gluconate, sodium citrate, sodium polyacrylate, sodium pyrophosphate, sodium potassium tartrate, sodium salt of a propylene copolymer, sodium polyaspartate, sodium tripolyphosphate and sodium polyepoxysuccinate.
Further, the oxidizing substance is selected from one or more of potassium permanganate, sodium chlorate, sodium hypochlorite, sodium chlorite, sodium percarbonate, sodium persulfate, potassium persulfate, ammonium persulfate, sodium perborate, or potassium perborate.
Further, the catalytic synergistic substance comprises one or more of chelated iron, chelated copper, chelated titanium, chelated nickel, chelated cobalt and chelated manganese.
Furthermore, the catalytic synergistic substance is one of chelated copper and chelated manganese or is composed of the chelated copper and the chelated manganese.
A soaping method is characterized by comprising the following steps: after the fabric, yarn or fiber is dyed or printed by the reactive dye, the anti-staining low-temperature soaping agent is added for soaping.
Further, the soaping temperature is
Preferably 70 ℃; the soaping time is
Preferably 20 min.
Further, the dosage of the reactive dye anti-staining low-temperature soaping agent is 0.1 g/L-0.5 g/L.
Compared with the prior art, the invention has the advantages that: in the soaping process of the reactive dye soaping agent, the alkaline substance can further hydrolyze the reactive dye which does not participate in the reaction so as to prevent the reactive dye from reacting and combining with the fiber; the inorganic salt has a synergistic effect on washing away the floating color; the chelating dispersant can chelate metal ions in the working solution to ensure that printed or dyed cloth has bright color, can remove floating color and dyes and other impurities in the dispersing working solution to prevent staining, and has good compatibility and synergistic interaction; the oxidant is used for oxidizing the unreacted active dye and hydrolytic dye in the working solution to destroy chromophoric groups of the reactive dye and the hydrolytic dye, so that the chroma of the soaping residual liquid is low and the staining resistance is lost, and the staining resistance effect is further ensured and enhanced. The oxidant is selected according to the temperature of the working solution and the oxidation capacity of the working solution, and the selected oxidant can only oxidize the reactive dye and the hydrolytic dye in the working solution, but can not oxidize the reactive dye which is reacted and firmly combined with the fiber, so that the chromaticity and the color fastness of the soaped fabric are ensured. Further, the catalytic synergistic substance can further lower the soaping temperature and improve the action efficiency of the oxidation component, and particularly when the chelated copper and the chelated manganese are cooperatively used as the catalytic synergistic substance, the soaping anti-staining effect is optimal.
