Nano silver-bamboo-charcoal dispersing liquid and method for preparing nano silver-bamboo-charcoal fiber

Abstract

The invention relates to the nano-silver bamboo charcoal dispersed liquid and the method of making nano-silver bamboo charcoal fiber. The aim is conquer the current domestic production of antibacterial fabric general defects. The art is press the viscose fiber pulp after two filters and the nano-silver bamboo charcoal dispersed liquid into the spinning machine to weave. The fiber can take far infrared emission, anti bacteria, and has adsorption function. The particle diameter of the nano-silver is 20-60nm, and the particle diameter of the bamboo charcoal < 0.5mum.

Description

Technical field: [0001] The invention relates to the technical field of preparation methods of nanofibers, in particular to nano silver bamboo charcoal dispersion liquid and a method for preparing nano silver bamboo charcoal fibers. Background technique: [0002] Nanotechnology is an emerging technology that emerged in the 1990s. Due to the special surface effect and small size effect of the particles that make up nanomaterials, they can produce different physical and chemical properties from conventional materials, such as high strength, high toughness, good conductivity and electrostatic shielding effect, anti-ultraviolet, absorption Visible light and infrared rays, anti-aging, has strong antibacterial and deodorizing functions and adsorption capacity and other characteristics. In recent years, nanotechnology has developed rapidly and swept the entire scientific and technological field. It has great development value and development prospects in textile finishing and prin...

Problems solved by technology

Finishing technology is to soak fibers, yarns, fabrics or garments in a solution containing antibacterial substances to achieve antibacterial effects. Since clothing often needs to be washed, antibacterial substances will be washed off the surface of its fibers, so this method is used The antibacterial effect of the produced antibacterial fiber is not durable, the washability is poor, and the antibacterial effect is low; the second is to use the method of adding organic antibacterial agents. The disadvantage of adding organic antibacterial agents is that they are not resistant to high temperatures, generally of dissolution type, and the antibacterial is difficult to last; It is the method of adding inorganic substances, that is, carrying copper, zinc, silver ions to compound other cations, and using technical means such as ceramic powder, activated carbon and rare earth activation. The disadvantage of using silver-zinc-copper composite spinning is that the fiber is easy to change color, The addition of inorganic substances is relatively large, which reduces the spinnability and dyeability of the fiber, reduces the strength of the fiber, and the antibacterial effect is not ideal. The addition of rare earths is easy to cause radiation damage and lacks safety.
