Embodiment 1

[0016] (1) Dissolve 0.01g of basic fuchsin in 300mL of deionized water, stir well, and after it is completely dissolved, transfer it to a water bath at 40°C; then immerse 10g of fully wetted cotton fabric into the dye solution Add 6g of sodium chloride after 15 minutes, and continue dyeing for 30 minutes under stirring conditions. After dyeing, cool down, take out the fabric, and wash it with deionized water for 3 times; In the 2g / L soaping solution, after soaping at 90°C for 15 minutes, wash with deionized water for 3 times, and dry at 60°C.

[0017] (2) Immerse the above-mentioned textiles in the reaction solution of 0.5mol / L hydrochloric acid and 10g / L ammonium persulfate, continue to stir evenly, oxidatively polymerize at 0°C for 18h, after the reaction, wash 3 times with acetone and distilled water respectively, and wash at 50°C After drying, the colored electromagnetic shielding fabric is obtained.

Embodiment 2

[0022] (1) Dissolve 0.5g of methylene green in 500mL of deionized water, stir well, and after it is completely dissolved, transfer it to an 80°C water bath; then immerse 10g of fully wetted viscose fabric into the dye solution After 15 minutes, add 30 g of anhydrous sodium sulfate, and continue dyeing for 75 minutes under stirring conditions. After dyeing, cool down, take out the fabric, and wash it with deionized water for 5 times; In the soaping solution with a concentration of 3g / L, after soaping at 95°C for 10 minutes, wash with deionized water for 5 times, and dry at 80°C.

[0023] (2) Immerse the above-mentioned textiles in the reaction solution of 2mol / L p-toluenesulfonic acid and 30g / L sodium persulfate, continue to stir evenly, oxidatively polymerize at 5°C for 5 hours, after the reaction, wash with acetone and distilled water 5 times respectively, Dry at 80°C to obtain a colored electromagnetic shielding fabric.

Embodiment 3

[0027] (1) Dissolve 0.2g of acridine orange in 400mL of deionized water, stir well, and after it is completely dissolved, transfer it to a 60°C water bath; then immerse 10g of fully wetted pure hemp fabric into the dyeing solution After 15 minutes, add 16g of sodium chloride, and continue dyeing for 60 minutes under stirring conditions. After dyeing, cool down, take out the fabric, and wash it with deionized water for 4 times; In the 2.5g / L soaping solution, after soaping at 92°C for 12 minutes, wash with deionized water 4 times, and dry at 70°C.

[0028] (2) Immerse the above-mentioned textiles in the reaction solution of 1mol / L sulfuric acid and 20g / L potassium persulfate, continue to stir evenly, oxidatively polymerize at 2°C for 10h, after the reaction, wash 4 times with acetone and distilled water respectively, and dry at 60°C After drying, a colored electromagnetic shielding fabric is obtained.

Abstract

The invention provides a preparation method for colored electromagnetic shielding fabric. The preparation method comprises the following steps: firstly, dyeing a textile by adopting organic dye which can be chemically polymerized; then, polymerizing the organic dye which is dyed onto the textile into conductive polymer through chemical polymerization. The obtained fabric has good shielding performance on low-frequency electromagnetic waves with frequency lower than 10MHz, and is excellent in soaping fastness.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of a colored electromagnetic shielding fabric. Background technique [0002] Electromagnetic wave radiation is the fourth largest global public hazard after water, air and noise, and has become an invisible "killer" that endangers human health. Electromagnetic shielding fabric is a commonly used anti-electromagnetic radiation material. When it first appeared, it was mainly used in the electronics industry. In recent years, as citizens pay more and more attention to their own health, electromagnetic shielding fabrics have developed rapidly in the civilian field. In particular, the emergence of radiation protection clothing for pregnant women has provided protection for the health of the mother and fetus. [0003] At present, there are mainly two types of electromagnetic shielding fabrics: one is a blended fabric of metal wire and textile fiber, ...
