[0021] To further explore the influence of the preparation raw materials and methods of the functional particles on the performance of the fabric, comparative examples 1-3 were set based on example 3, and the specific settings were as follows: ①Comparative examples 1 and 2, compared with example 3, only the components of the mixed acid solution in step (2) were adjusted. The components of the mixed acid solution used in example 3 and comparative examples 1-3 are shown in the following table: ; ②Comparative example 3, compared with example 3, only the mass ratio of glycyrrhetic acid to dodecylbenzenesulfonic acid in the mixed organic acid in step (2) was 1:3; ③Comparative example 4, compared with example 3, only the mixed organic acid in step (2) was replaced by an equal amount of glycyrrhetic acid; ④Comparative example 5, compared with example 3, only the mixed organic acid in step (2) was replaced by an equal amount of dodecylbenzenesulfonic acid.

[0022] Fabric performance detection Equal-sized sample fabrics were obtained from the fabrics obtained in examples 1-3, the blank example, and comparative examples 1-5. The performance of each sample fabric was detected in turn, and the detection items and schemes were as follows: (1) Antistatic performance detection: Under the conditions of 20% and 50% humidity, the antistatic performance of each fabric sample was detected according to the standard of GB / T 12703.1-2021 "Textiles - Test methods for electrostatic properties - Part 1: Corona charging method", and the electrostatic voltage half-life period was used as the test index (first level: half-life period ≤6s; second level: 6< half-life period ≤15; third level: 15< half-life period ≤30; fourth level: 30< half-life period ≤60, fifth level: >60s). The detection results are shown in the following table: ; From the above table, it can be seen that: Compared with the blank example and comparative examples 1-5, examples 1-3 all showed excellent antistatic performance, and the antistatic performance was not obviously affected by the environmental humidity; Compared with Example 3, in Comparative Example 1-2, due to the removal of the extract of scytonema and mixed organic acid in the raw material of the functional particles when mixing the functional particles in the preparation of the functional fiber, the antistatic property of the fabric obtained in Comparative Example 1 is significantly reduced when the environmental humidity is reduced, and the antistatic property of the fabric obtained in Comparative Example 2 is also significantly reduced; In Comparative Example 3, when the mixed organic acid used in the preparation of the functional particles is used, the content of dodecylbenzenesulfonic acid is greatly increased, and the content of glycyrrhizinic acid is reduced, and in Comparative Examples 4 and 5, dodecylbenzenesulfonic acid and glycyrrhizinic acid in the mixed organic acid are removed, respectively, which leads to a significant reduction in the antistatic property of the fabric; The above results show that the preparation method of the antistatic fabric for embroidery provided by the application can significantly improve the antistatic property of the fabric and the stability of the antistatic property under different humidity conditions by using the functional fiber doped with the functional particles. It is inferred that the reason is that the mixed organic acid obtained by compounding glycyrrhizinic acid and dodecylbenzenesulfonic acid has good conductivity after interacting with polyaniline to form functional particles, and the corresponding functional fiber also has good conductivity.

[0023] (2) Air permeability detection: according to the provisions of GB / T5453, the sample is fixed flat on the sample table surface with a circular air hole in the center, the rubber gasket is used to cooperate with the clamp to seal and fix the edge of the sample to prevent air leakage, the air flow rate through the given area of the sample per unit time is measured, and the air permeability is calculated; (3) Hygroscopicity detection: under the condition of 50% relative humidity and 25℃, the fabric is weighed once to obtain W1, then the fabric is dried at 110℃ for 2.5h, and then weighed again to obtain W2, and the hygroscopicity of the fabric is calculated according to the weight difference before and after drying, and the calculation formula is: W(%)=(W1-W2) / W2×100; The detection results of air permeability and hygroscopicity are shown in the following table: ; From the above table, it can be seen that: Compared with the blank sample and Comparative Examples 1-2, the air permeability and moisture absorption performance of the fabric obtained in Example 1-3 are both better. Comparative Examples 1 and 2 both show a decrease in air permeability and moisture absorption performance due to the use of incomplete mixed acid solution formula, and the decrease in moisture absorption performance of the fabric caused by the absence of the extract of scytonema in Comparative Example 1 is particularly significant. Comparative Examples 3-5 also show a decrease in air permeability and moisture absorption performance due to the use of incomplete mixed organic acid formula, and the decrease in air permeability of the fabric caused by the absence of glycyrrhetinic acid in Comparative Example 5 is particularly significant. It is inferred that the reason is that glycyrrhetinic acid is used in combination with the extract of scytonema in the functional fiber, and the hydrophilic groups rich in the extract of scytonema endow the functional fiber with good water absorption and water retention. On the fabric blended with an appropriate amount of functional fiber, water does not spread widely, so that the gaps between the fibers of the fabric can be fully exposed, thereby showing good air permeability.

[0024] The above-described examples only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the patent of the present application. It should be noted that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
