Abstract

The invention relates to a preparation method of an anti-microbial conductive acrylic fiber / copper sulphide complex fiber. The preparation method comprises the steps of pretreating acrylic fiber; immersing the pretreated acrylic fiber into a copper sulfate solution, stirring, keeping in water bath with the temperature ranging from 40 to 80 DEG C for 1 to 2h, then adding a chelating agent solution, immersing and drying for three times, then adding the obtained acrylic fiber into a sodium sulfide solution, reacting at room temperature for 10 to 30min, cleaning, and drying to obtain the anti-microbial conductive acrylic fiber / copper sulphide complex fiber. The anti-microbial conductive acrylic fiber / copper sulphide complex fiber prepared by the invention not only has favorable antibacterial property, electrical conductivity, binding strength, washing fastness and the like, but also is moderate in preparation conditions, simple in process and low in cost.

Description

technical field [0001] The invention belongs to the field of functional textiles, in particular to a preparation method of an antibacterial conductive acrylic fiber / copper sulfide composite fiber. Background technique [0002] Acrylic fiber is the trade name of polyacrylonitrile fiber (PAN) in China. As one of the three major synthetic fibers, acrylic fiber has been industrialized by DuPont in the United States since the 1950s. Acrylic fiber has the characteristics of wool, and has the advantages of large output, bulky texture, soft hand feeling, good weather resistance and light resistance, and is widely used in textiles such as clothing, car seats and curtains. However, due to its hydrophobicity and insulating properties, its electrostatic phenomenon is serious. However, the impact of static electricity on human society is well known, for example: in petrochemical and other flammable and explosive environments, accidents such as explosions and burning are caused by the d...
