AI Technical Summary

Technical Problem

Existing antibacterial and deodorizing technologies for socks suffer from limited deodorization rates, slow adsorption effects, and short-term antibacterial performance due to the detachment of silver compounds from the sock surface and insufficient cooperative antibacterial action between carriers and metal ions.

Method used

A rare earth composite functional filler is produced by a precipitation method, combining rare earth elements with zinc carbonate and silver, forming a flaky structure that enhances antibacterial and deodorizing properties through synergistic action with Ag and Zn ions, supported on a La2O2CO3-CeO2 carrier.

Benefits of technology

The rare earth composite filler exhibits long-lasting antibacterial and deodorizing effects, improves fabric properties like heat resistance and comfort, and maintains stability under friction and washing, with enhanced antibacterial performance compared to conventional methods.

Abstract

This invention provides a rare earth composite functional filler for antibacterial and deodorizing socks, and a method for producing the same. [Solution] A method for manufacturing a rare earth composite functional filler for antibacterial and deodorizing socks includes the following steps: S1. Production of rare earths and zinc carbonate; S2. Production of a rare earth composite. In the rare earth composite functional filler for antibacterial and deodorizing socks manufactured by the above method, the flake-shaped carrier itself has antibacterial and deodorizing properties, and Ag and Zn 2+ By working in conjunction with it, antibacterial and deodorizing properties are significantly improved.
