Problems solved by technology

These colored substances will not only color the antibacterial fiber, narrowing the application range of the fiber; but also in the process of high-temperature melting granulation, spinning and cooling, the raw copper will further react with water and oxygen, making the product in the back-end application At the same time, the color is changeable and uneven, and the valence state and existence state of copper are different, and the color difference is large

Abstract

The invention discloses white copper-based antibacterial fiber and a preparation method thereof. The antibacterial fiber comprises the following raw materials of 0.4%-15% of a white copper-based alloy nano-powder antibacterial agent, 0.2%-1.5% of a lubricant, 0.2%-1.5% of an antioxidant, 0.2%-1.5% of a dispersant and the balance of matrix resin, wherein the average particle size of the white copper-based alloy nano-powder antibacterial agent is 200-700 nm. The white copper-based antibacterial fiber provided by the invention has the characteristics of good antibacterial broad spectrum, good color uniformity and consistency, wide dyeing range, low color matching difficulty and cost and good washing resistance.

Description

technical field [0001] The invention belongs to the field of composite material engineering, and in particular relates to a white copper-based antibacterial fiber and a preparation method thereof. Background technique [0002] Antibacterial fibers have high application value in the preparation of functional antibacterial textiles, functional medical dressings and other fields. Copper can inhibit the growth of bacteria, viruses and fungi at the same time, and has good antibacterial broad-spectrum; at the same time, copper is also one of the trace elements needed by the human body, safe, non-toxic, and environmentally friendly. Copper-based antibacterial fibers can increase the added value of textiles and meet people's needs for safety, health, and environmental protection. Therefore, they have attracted more and more attention and have huge market potential. [0003] At present, the copper raw materials selected for the existing copper-based antibacterial fibers on the marke...
