Cuprous oxide base antibacterial fibers and preparation method thereof

Abstract

The present invention relates to cuprous oxide base antibacterial fibers and a preparation method thereof. The preparation method comprises: (1) adding cuprous oxide powder, a dispersant and a modifier to an aqueous medium, and carrying out grinding, dispersion, modification and drying to obtain modified cuprous oxide powder; (2) uniformly mixing the modified cuprous oxide powder in the step (1) and master batches (such as polyester, nylon and the like) with different varieties according to a mass ratio of 1:1-1:50, and carrying out granulation to obtain antibacterial master batches (such as polyester, nylon and the like) with different varieties; and (3) uniformly mixing the prepared antibacterial master batches and ordinary master batch according to a mass ratio of 1:1-1:50, adding the obtained mixture to high speed spinning equipment, and carrying out melt-spinning and winding to obtain the fiber product. According to the present invention, the method has characteristics of simple process and easy industrial production; and the fibers prepared by the method have characteristics of original fiber characteristic maintaining and broad-spectrum antibacterial property, wherein the antibacterial rate is more than 99%.

Description

technical field [0001] The invention relates to a cuprous oxide-based antibacterial fiber and a preparation method thereof, belonging to the field of new materials and material preparation. Background technique [0002] Since the 20th century, with the development of science and technology and the improvement of people's living standards, people's awareness of health and health care has become stronger and stronger, and the research and development and production of various antibacterial fibers and textiles have become more and more popular. focus on. At present, most antibacterial fabrics are obtained by coating the antibacterial agent on the fabric by dipping or coating after finishing. This kind of antibacterial fabric is not washable. With the increase of washing times, the antibacterial agent is peeled off and the antibacterial effect is also reduced. Then lost. The antibacterial agent is added in the spinning process so that it can be evenly distributed in the fiber ...

AI Technical Summary

Problems solved by technology

However, natural antibacterial agents are often restricted by safety and processing conditions, making it difficult to achieve large-scale production; organic antibacterial agents are mostly volatile, and are likely to cause irritation or damage to the skin; and inorganic antibacterial materials are weather-resistant, heat-resistant, and long-lasting. and non-polluting advantages, showing a good momentum of development and application prospects

Among the inorganic antibacterial agents, the antibacterial agents with low toxicity and bactericidal ability mostly use Ag + , Zn 2+ and Cu 2+ etc. (J.Ceram.Soc.Jpn., 2008,116,767-770), at present, commercialized inorganic antibacterial agents at home and abroad also mostly use Ag + , Zn 2+ 、Cu 2+ etc., but due to Ag + The price is high and the cost is difficult to control; Zn 2+ Has lower antibacterial activity, so research and preparation can replace Ag + Antimicrobials are of great importance

Cu + The antibacterial activity is higher than other substances (Cu 2+ , Zn 2+ etc.) and second only to Ag + , but its application in antibacterial materials is limited due to its instability and difficulty in exchange into carriers.
