Background
The reactive dye dyeing is the main dye variety for dyeing the cellulose fiber and blended fabric at present, and the dosage of the reactive dye is increased year by year. Reactive dyes are various in types, chemical structures and reaction efficiency, but the reactive dyes cannot completely react with fibers. In addition, when the fixed fiber is dyed, the dye can be hydrolyzed, the diffusion and adsorption properties of the unfixed dye and the hydrolyzed dye are very similar to those of the original active dye, the unfixed dye and the hydrolyzed dye are easy to adsorb on the surface of the fiber and diffuse into the fiber, and can be combined with the fiber under certain conditions, so that the impurities can be removed only by multiple washing and soaping processes, so that the color brightness, the color fastness and the cleanliness of the fabric are improved, and the process of removing the impurities is called soaping.
The common polyester-cotton one-bath soap lotion is mainly used for intermittent dip dyeing of polyester-cotton blended knitted fabrics, has poor adaptability to a continuous pad dyeing process, cannot synchronously realize synchronous dyeing operation of disperse dyes and reactive dyes, is not beneficial to improvement of production efficiency, and needs a polyester-cotton one-bath soap lotion which can be adapted to the continuous tie dyeing process to solve the problem.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Example (b): a preparation method of a soaping agent for one-step pad dyeing of polyester-cotton blended woven fabric comprises the following steps:
s1, adding 166.13g of isophthalic acid-5-sodium sulfonate, 500g of solvent ethylene glycol and 10g of catalyst p-toluenesulfonic acid into a reaction kettle together, and heating to 150-190 ℃ for esterification reaction to obtain diethylene glycol terephthalate;
s2, cooling the diethylene glycol phthalate obtained in the S1 to below 100 ℃, then continuously adding 200g of fatty alcohol-polyoxyethylene ether and 200g of PEG with the molecular weight of 4000, then adjusting the pH value of the whole mixture to 7-7.5 by using acetic acid, heating to 240-260 ℃, and fully mixing;
and S3, vacuumizing the mixture obtained in the S2 for 1-2 hours until the vacuum degree is lower than-0.095 MP, performing reduced pressure polycondensation, then decompressing, cooling to 70-85 ℃, and discharging to obtain the product.
The reaction equation is
The molecular weight of the product prepared by the method is 3000-5000.
The technical scheme has the advantages that the soaping agent prepared by the method can simultaneously dye the polyester component and the cotton component, so that the reduction cleaning process after the polyester is dyed is reduced, the one-step dyeing of the disperse dye reactive dye is realized, the process time is shortened by 50%, and the color fastness grade of the traditional two-step method can be achieved.
The reason for introducing the fatty alcohol-polyoxyethylene ether is that the fatty alcohol-polyoxyethylene ether is used for producing fatty alcohol-polyoxyethylene ether sodium sulfate (AES) in large quantity, and the physical properties of the fatty alcohol-polyoxyethylene ether make the fatty alcohol-polyoxyethylene ether not favorable for preparing washing powder, but the fatty alcohol-polyoxyethylene ether is an ideal raw material of a liquid detergent. It has better detergency to various fibres than sodium alkylbenzenesulfonate, and is especially suitable for washing the grease dirt discharged from human body from synthetic fibre fabric. The main application of fatty alcohol-polyoxyethylene ether is as synthetic detergent. The domestic commercial brand is a Pingpingan series product, except that part of the product is used for compounding a liquid detergent, the product is mainly used as a leveling agent and a stripping agent in the printing and dyeing industry, as a raw wool detergent in the wool spinning industry and as a spinning oil agent in the chemical fiber industry; in addition, the application is that the nonionic surfactant is widely used as a leveling agent of various dyes and a stripping agent of vat dyes in the textile industry, and the common dosage of the wool retarding agent is 0.2-1/L. The product can be used as a component of synthetic fiber spinning oil agent such as terylene and the like, is used as an emulsifier in the latex industry and petroleum drilling fluid, has unique emulsifying property on stearic acid, paraffin, mineral oil and the like, is a component of the emulsifier during the polymerization of high molecular emulsion, and can also be used as an emulsifier of glass fiber lubricating oil, can remove dirt dispersed and aggregated on fabrics by dye, improve the decontamination capability of sodium alkyl benzene sulfonate synthetic detergent, and reduce the antistatic effect of the fabrics; the chemical cleaning is mainly used as a wetting agent in degreasing. The grease component is almost not dissolved with water in acid liquor, and is also rather insoluble in alkali solution, in order to accelerate emulsification and strengthen contact with the alkali solution, nonionic surfactants such as fatty alcohol-polyoxyethylene ether can be used as wetting agents during alkali washing, and in order to accelerate permeation of cleaning solution in hard compact scale, the surfactants can be used during acid washing; in addition, the corrosion inhibitor can also be used as a component of certain composite corrosion inhibitors to play a synergistic role.
The fatty alcohol-polyoxyethylene ether is introduced into the preparation of the soaping agent for one-step pad dyeing of the polyester-cotton blended woven fabric, so that the emulsifying and cleaning performance of the whole soaping agent can be effectively improved, and the whole product can reach the color fastness grade of the traditional two-step method when the tie-dyeing efficiency is improved.
