Abstract

The invention discloses nano copper oxide cellulose fiber having strong bacteriostasis and washing-resisting performance. A preparation method comprises the following steps: cellulose fiber anionization, chitosan modification, nano copper oxide modification, and chitosan coating in order. The nano copper oxide particles are coated between two layers of chitosan, a chitosan / nano copper oxide / chitosan composite functional layer is prepared, chitosan and nano copper oxide perform synergistic antibacterial effect, and adhesion performance, bacteriostasis and washing-resisting performance of the nano copper oxide particles are greatly increased.

Description

technical field [0001] The invention relates to a nano-copper oxide cellulose fiber with strong antibacterial and washable properties, which belongs to the field of textile materials and functional nanometer materials. Background technique [0002] Since the 1990s, with the improvement of measurement and characterization techniques, nanomaterials and nanotechnology have developed rapidly. Nanomaterials refer to materials with a size of 1-100nm. Different from bulk materials, they have unique optoelectronic properties and have been widely studied and applied in various fields such as electronics, materials, medicine, biology, machinery, textiles, printing and dyeing. As far as the textile field is concerned, the combination of nanomaterials and textiles can effectively improve the inherent defects of textiles, expand the scope of application of textiles, and increase the added value of textiles. A large number of research results show that the use of organic or inorganic nan...
