The cold mass pretreatment assistants of examples 1-3 and comparative examples 1-8 were subjected to a combination of properties, and the test results are shown in Table 1. The test conditions were: 10g/L of cold reactor pretreatment auxiliary agent and NaOH (100 percent): 50g/L, H 2 O 2 (100 percent) 20g/L, twice soaking and twice rolling, the rolling residual rate is 80-100 percent, piling for 16 hours, washing with hot water, washing with cold water, and measuring the hair effect.
TABLE 1 results of Performance test of examples 1-3 and comparative examples 1-8
The test results show that: examples 1-3 and comparative examples 5-8 all maintained a stable state at 100g NaOH/L (1% concentration), cold mass Mao Xiaogao (. Gtoreq.6 cm), and had good whiteness (. Gtoreq.80%), and were superior in performance overall properties to comparative examples 1-4. It was found from comparative examples 1 to 3 and comparative examples 1 to 3 that the kinds and contents of amphoteric polymer surfactants significantly affect alkali resistance, capillary effect of cold mass and whiteness. Example 3 in comparison to comparative example 4 found that the absence of chelating agent resulted in a reduction in cold stacking whiteness. Comparison of example 3 with comparative example 5 shows that the lack of fatty alcohol polyoxyethylene ether results in reduced cold pile hair efficiency. Example 3 was compared with comparative example 6, and it was found that the lack of the isomeric alcohol polyoxyethylene ether resulted in poor permeation and reduced hair effect. Example 3 was compared with comparative example 7 and found that due to the lack of organic defoamer, a large amount of foam was generated during use, which was detrimental to the padding of the working liquid into the cloth cover, affecting the hair effect. Example 3 compared with comparative example 8 found that further increases in the amount of amphoteric polymeric surfactant, the cold piling efficiency and cold piling whiteness did not increase further, but rather increased the cost. The results of the combination of example 3 and comparative examples 4-8 show that the specific combination of example 3 provides excellent performance of the cold-stack pretreatment auxiliary, the components are synergistically enhanced, the hair effect and whiteness performance are good, and the excellent combination of example 3 cannot be achieved without any component.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or substituted equally without departing from the spirit and scope of the technical solution of the present invention.
