Embodiment Construction

[0022] A kind of preparation technology of the metal wool composite fiber with electromagnetic shielding function of the present invention, comprises the following steps successively:

[0023] Step 1: After removing surface impurities, the cotton fiber is immersed in a sodium hydroxide solution with a concentration of 15% to 20%, stirring and dipping to make the cotton fiber fully contact with the sodium hydroxide solution;

[0024] Step 2: Take out the cotton fiber treated in step 1 to control the dry water, immerse the cotton fiber in deionized water for cleaning reaction, use ultrasonic vibration to strengthen the cleaning effect, wash repeatedly until the filtrate is neutral, take out the dry water , and then dried at 80-90°C for 2-3 hours to make modified cotton fibers;

[0025] Step 3: After removing the surface impurities, the oxygen-free copper long fiber is immersed in silver nitrate with a concentration of 10-15%, and after standing for 3-4 hours, the water is contro...

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of chemical textiles, in particular to the technical field of a preparation process of a metal wool composite fiber with electromagnetic shielding function. [0003] 【Background technique】 [0004] As people increasingly pay attention to wearing health and advocating nature, cotton fiber has established its important position from many chemical fibers. As one of the four natural fibers cotton, wool, silk and hemp, cotton fiber has always been favored by people because of its unique and excellent properties such as softness, warmth and comfort. With the advancement of electronic technology in today's world, people usually have to face various complex electromagnetic environments in transportation, communication, office, and life. Due to the long-term "cumulative effect" of electromagnetic radiation, people pay more and more attention to electromagnetic protection. However, most of the existing cotton...
