[0082] Based on the above experimental data, the following conclusions are drawn:

[0083] From the data of Examples 1-6 and Comparative Examples 1-3, it can be seen that the heat preservation of the fabrics of Examples 1-6 and Comparative Examples 1-3 before washing is above 7 points, and the moisture retention of the fabrics is satisfactory.

From the observation of Example 6 and Comparative Example 2, it can be seen that the moisture retention of the fabric in Comparative Example 2 also decreases. By comparing Comparative Example 3 with Comparative Example 1 or Comparative Example 2, it can be seen that the moisture retention performance of Comparative Example 3 decreases significantly after multiple washings. It can be seen that the activated epoxy resin solution and the hyaluronic acid solution The hyaluronic acid microcapsules prepared after mixing are modified to enhance the water-washing resistance of the fabric's moisture retention, so that the fabric can still maintain a good moisturizing effect after multiple washings; from the observation of the fabric's water washing color fastness, dry friction fastness and wet friction fastness in Example 6 and Comparative Example 1 or Comparative Example 2, it can be seen that the epoxy resin solution activated by castor oil sodium sulfate can not only enhance the fabric's antistatic properties, but also has a certain improvement effect on the fabric's water washing color fastness, dry friction fastness and wet friction fastness. After the activated hyaluronic acid microcapsules are modified, the color fastness and friction fastness of the fabric are improved, preventing the fabric from subsequent discoloration and breakage.
