By combining the example 1 and the comparative examples 1 to 3, the color fastness of the coated yarn can be improved by adding the auxiliary coloring agent into the dye; by combining the examples 4-9 and the examples 1-3, the color fixing agent is added into the auxiliary coloring agent, the ammonium polyvinyl chloride and the diallyl amine hydrochloride in the color fixing agent contain a large amount of cations, and the cations are combined with the anions in the dye to generate insoluble compounds to be precipitated on the fibers, so that the color fastness of the coated yarns is improved; combining the example 1 and the comparative example 2, it can be seen that the m-beta-hydroxyethyl sulfone sulfate aniline contains vinyl sulfone groups, and the m-beta-hydroxyethyl sulfone sulfate aniline and hexamethylphosphoric triamide synergistically act to promote monochlorotriazine-beta-cyclodextrin to be fixed on the surface of the fiber, so that the color fastness of the coated yarn is improved; combining example 1 and comparative example 3, it can be seen that hexamethylphosphoric triamide is alkaline, promoting the activity of vinyl sulfone group, further improving the color fastness of the coated yarn.
(2) And (3) testing the coloring rate: dyeing the coated yarn by using the dye solution of each example and the comparative example, and testing the dyed coated yarn by using a type 722 spectrophotometer; the standard GBT23976.1-2009 color rating assay was used.

According to the combination of the embodiment 4-7, quaternary ammonium salt is added into the color fixing agent, wherein the quaternary ammonium salt contains quaternary ammonium groups, and the quaternary ammonium groups can enhance the activity of cations in the color fixing agent, promote the combination of the cations and anions in the dye, and improve the coloring rate of the coated yarn; by combining the embodiment 1 and the embodiments 8-9, the higher the temperature is, the higher the dyeing rate is in the process of coating silk dyeing; by combining the embodiment 1 and the embodiment 12, the fatty alcohol-polyoxyethylene ether is added into the refining solution, and the pectin can be removed by the fatty alcohol-polyoxyethylene ether, so that the dyeing is facilitated, and the dyeing rate is further improved.
(3) And (3) softness detection: subjective hand feeling test is carried out on the coated yarn by textile experts; the softness of the coated yarn was classified into 6 grades, 1 being very soft, 2 being soft, 3 being softer, 4 being harder, 5 being hard, 6 being very hard.
TABLE 3 softness test results
| Sample (I) | Softness grade |
| Example 6 | 3 |
| Example 7 | 2 |
It can be seen from the combination of example 6 and example 7 that sodium tripolyphosphate is added to the color fixing agent, and the sodium tripolyphosphate can perform a complex reaction with metal ions such as calcium ions and magnesium ions in the dye to generate a complex compound which is easily dissolved in the dye solution, so that the metal ions are prevented from being deposited on the surface of the fiber, and the softness of the coated yarn is improved.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
