Problems solved by technology

In short, most organic synthetic antibacterial agents have short antibacterial cycles, poor safety and chemical stability, and are prone to microbial resistance, which limits their application range.
More importantly, metals, metal oxides, and organic antibacterial agents are all produced from non-renewable resources. Under the impact of resource crisis, the manufacturing cost of these antibacterial agents will inevitably increase significantly, which is not conducive to the development of antibacterial finishing

Abstract

The invention discloses a settling method for a long-acting washable natural antibacterial fabric. The method comprises the following steps: (1) padding the fabric in an antibacterial essential oil liposome suspension, soaking for two times and padding for two times; (2) treating the fabric acquired in the step (1) with ultraviolet radiation under the condition of oxygen partial pressure at 0.5-0.8 Pa, wherein the scope of ultraviolet wavelength is 200-400nm, the radiation time is 30-60s, and the strength of ultraviolet radiation on the fabric surface is 80-100mW / cm<2>; and (3) adopting a natural cross-linking agent for cross-linking the fabric treated in the step (2), washing with water and then drying. According to the method disclosed by the invention, the natural antibacterial settling agent and auxiliaries are adopted, so that the use of compound chemicals is greatly reduced, the settling method is more environment-friendly, the biocompatibility of the fabric products is better, the volatility and release property of essential oil are greatly reduced, the fastness to washing and the tearing strength of the fabric are increased, and the antibacterial function of the fabric is enhanced.

Description

technical field [0001] The invention relates to the technical field of functional textiles, in particular to a finishing method for long-lasting washable natural antibacterial fabrics. Background technique [0002] With the change of consumption concepts and health concepts, people have new requirements for textiles, and textiles with health care effects are very popular. [0003] Nano-silver, nano-zinc oxide, nano-ceramic powder, TiO 2 And other inorganic antibacterial agents are used in cotton fabric finishing, which can obtain better antibacterial health care performance. However, metal ions are easily converted into oxides or reduced to simple substances to change color, affecting the color of fabrics, especially silver ions or nano-silver particles have potential toxicity to the reproductive system and liver. Some photocatalyzed metal oxides have poor antibacterial effects on skin surfaces protected from light. In addition, the metals in the fabric cannot be transfor...
