Antibacterial viscose fiber added with rare earth oxide and preparation method of antibacterial viscose fiber

Abstract

The invention discloses an antibacterial viscose fiber added with rare earth oxide and a preparation method of the antibacterial viscose fiber. The antibacterial viscose fiber is prepared from the following raw materials in parts by weight of 20 to 30 parts of rare earth antibacterial powder, 6 to 12 parts of dispersing agent, 50 to 55 parts of water and cellulose, wherein the rare earth antibacterial powder takes cerium oxide as a base, and the balance is one or more of other rare earth oxides and copper oxide. The rare earth antibacterial powder with good antibacterial performance is selected, the rare earth antibacterial powder is prepared into the nano rare earth antibacterial suspension through an appropriate dispersion system and a sanding process, the viscose spinning mixed solution is prepared through an appropriate adding mode, the obtained rare earth antibacterial suspension is good in dispersion performance, is matched with the high viscosity and alkalinity of a viscose system, and is easy to add; and the obtained antibacterial viscose fiber is durable in antibacterial effect and wide in antibacterial spectrum.

Description

technical field [0001] The invention belongs to the field of functional fiber preparation, and in particular relates to an antibacterial viscose fiber added with rare earth oxides and a preparation method thereof. Background technique [0002] In the prior art, the inorganic nano antibacterial suspension with high solid content and good dispersibility is not easy to prepare, and the suspension cannot maintain suspension for a long time. Because the viscose collagen solution has the characteristics of high alkalinity, if the inorganic antibacterial suspension is added to the viscose collagen solution, the particles are easy to agglomerate and agglomerate, which affects the spinning of viscose. Although the organic antibacterial suspension has good compatibility with the viscose collagen solution, its cost is high, and the organic antibacterial agent has poor heat resistance, is easy to decompose and lose efficacy, and the toxic decomposition products may cause secondary pollu...

AI Technical Summary

Problems solved by technology

First of all, the role of the rare earth in this patent application is: the rare earth element is coated on the surface of the titanium dioxide antibacterial agent, and it is not easy to lose, thereby improving the antibacterial and antifungal properties of the product, but the rare earth element itself does not play an antibacterial effect

Secondly, the patent application uses a non-aqueous system suspension, which does not match the viscose preparation process (aqueous system suspension is required)
