The soaping agent is used for the soaping process of the cellulose fiber dyed by the reactive dye with the ultralow bath ratio, so that various problems caused by salt content in a working bath, soaping agent residue and the like during soaping with the ultralow bath ratio and the problem that the soaping color fastness of the fabric does not reach the standard can be solved.
Description
Technical Field
The invention particularly relates to a soaping processing aid for dyed reactive dyes and an application method thereof, and particularly relates to a salt-resistant soaping agent for ultralow bath ratio and a soaping process thereof.
Background
The fabric printing and dyeing is usually processed by taking water as a medium, the reduction of the water consumption and the wastewater discharge are development trends of modern printing and dyeing technologies, printing and dyeing technologists continuously improve dyeing equipment and printing and dyeing processes, the bath ratio is reduced from 1: 8-10 to the ultra-low bath ratio (1: 2-4), and the development of the ultra-low bath ratio printing and dyeing has important significance in the aspects of water saving, energy saving and emission reduction.
The color fastness of the dyed product is improved, particularly reactive dyes, unfixed dye and hydrolyzed dye on the fabric need to be removed after dyeing, and soaping is generally adopted. Soaping agent needs to have the following properties: the influence on the color change of the fabric is small; the capability of removing the hydrolyzed dye and the unfixed dye is strong; preventing the dye in the dye liquor from being stained again; low or no foam. The dyeing process of the reactive dye needs to add a large amount of electrolyte, such as anhydrous sodium sulphate or salt. Before soaping, the concentration of electrolyte is required to be lower than 2g/L, and one is as follows: the electrolyte with higher concentration is not beneficial to the desorption of hydrolyzed dye and fixed dye, slows down the diffusion speed of the electrolyte from the interior or the surface of the fiber to water and reduces the soaping effect; the second is that: the washing dispersibility of the common soaping agent in the electrolyte solution with higher concentration is obviously reduced, and the soaping effect is reduced.
Because the ultra-low bath ratio printing and dyeing technology uses less water in each bath, if the electrolyte content is reduced to 2g/L and the soaping agent residual liquid is thoroughly washed after soaping, the number of baths needing washing is large, and the purposes of saving water and reducing emission cannot be achieved. Therefore, the soaping agent in the ultra-low bath ratio soaping needs to satisfy the following requirements in addition to the above requirements: the critical micelle concentration is smaller; the solubility is higher; electrolyte resistance; has good compatibility with cation assistants (such as color fixing agent and the like).

It is therefore an object of the present invention to provide a soaping agent composition containing components which do not require the electrolyte concentration in the working bath to be reduced to 2g/L (i.e. electrolyte resistance, reduced number of water-bath baths before soaping) when the composition is used in the soaping step.

The salt-resistant soaping agent, the commercially available soaping agent A (maleic acid-acrylic acid copolymer, active ingredient content is about 40%) and the nonionic soaping agent B (fatty alcohol-polyoxyethylene ether mixture, active ingredient content is about 25%) prepared in examples 1 to 4 were used for performance measurement at an ultra-low bath ratio, and the specific experimental process and the obtained data are explained and verified below. The results are shown in tables 1, 2 and 3.
1. Soaping resistance color fastness test
The determination is carried out according to GB/T32598-2016 instrument rating method for textile color fastness test lining fabric staining.
2. Compatibility testing of auxiliaries
Diluting according to the specified dosage (20 g/L of each auxiliary agent), compounding, and standing for 6h to observe the stability of the solution. The solution turns milky white or delaminates, precipitates, indicating poor product compatibility stability.
TABLE 1 compatibility of soaping agent with other adjuvants
As can be seen from table 1, the soaping agent with different structures has different compatibility with sodium chloride, anhydrous sodium sulphate, an anion penetrating agent and an aldehyde-free color fixing agent, and the soaping agent a (maleic acid-acrylic acid copolymer, the content of effective components is about 40%) reacts with the cationic aldehyde-free color fixing agent to generate white sticky substances, so that the soaping agent is easy to stain on fabrics and equipment to cause dyeing defects and equipment pollution; the nonionic soaping agent B (fatty alcohol-polyoxyethylene ether mixture, the content of active ingredients is about 25 percent) does not react with anion or cation auxiliary agent, but is easy to separate out and layer in high sodium chloride and anhydrous sodium sulphate bath, so that the phenomena of reduced washing capacity and uneven washing are caused; the salt-resistant soaping agent for ultralow bath ratio prepared in the embodiments 1 to 4 has no adverse reaction phenomenon after being mixed with sodium chloride, anhydrous sodium sulphate, an anion penetrating agent and an aldehyde-free color fixing agent, so that the salt-resistant soaping agent is supposed to have good compatibility with other auxiliaries and to have small risks of generating auxiliary spots, color stain spots and the like.
TABLE 2 soaping Effect (soaping fastness/grade) under different salt (sodium chloride, anhydrous sodium sulphate) conditions
As can be seen from Table 2, the higher the contents of sodium chloride and anhydrous sodium sulfate in the soaping liquid, the poorer the soaping effect of the soaping agent, and the salt-resistant soaping agents for ultralow bath ratios prepared in examples 1 to 4 are relatively less affected by the contents of sodium chloride and anhydrous sodium sulfate.
TABLE 3 influence of soaping agent residue on fixation (soaping fastness/level) and phenomena
As can be seen from table 3, if more anionic soaping agent remains in the working bath and on the fabric, the influence on the color fixing effect of the color fixing agent is larger, and meanwhile, substances generated by the reaction between the auxiliary agents easily stain the fabric or equipment, and the fabric needs to be repaired or scrapped; the nonionic soaping agent B has no adverse effect on the color fixing effect of the color fixing agent, and the residue causes foam generation and brings trouble to the running of the fabric. The salt-resistant soaping agent for ultralow bath ratio prepared in the embodiments 1-4 has no influence on the color fixing effect of the color fixing agent and has no foam.
By integrating the application performance analysis, the salt-resistant soaping agent for ultralow bath ratio prepared in the embodiments 1 to 4 meets the water saving requirement of the salt-resistant soaping process for ultralow bath ratio.
