Manufacturing Method and Characteristics of Nanocopper Fiber Yarn

Abstract

In this study, several samples of nanocopper fiber fabrics with different proportions of copper content were used. Among them, black copper antibacterial staple Polyamide fiber (PA) and 6 wt.% copper antibacterial fabric were selected. Positron emission tomography (PET) and other fabrics containing nanocopper components were used as experimental control samples. In the process, a raw material containing blending slurry, a nanometal solution, several inorganic particles, and thermoplastic polyurethane colloidal particles were used. The raw material was mixed and stirred before being dried and hot-melted. In the first stage of the process, the wire was cooled vigorously for conversion into the second stage form where it became a final product, a nanocopper fiber yarn. Taguchi analysis was used to compare the antibacterial property of the nanocopper powder between different particle sizes under the same distribution, weight, and fiber granulation characteristics. Two bacterial species, specifically Escherichia coli and Staphylococcus aureus, were used to investigate the antibacterial property of the fabric. In addition, we investigated the mechanical properties of the fabric and observed its surface structure. The copper content in the nanocopper fiber fabrics was detected using an X-ray fluorescence spectrometer. This finding indicate that the samples contained copper antibacterial components fabrics. Subsequently, the uniformity and aggregation degree of the copper distribution on the fiber fabrics were compared between different fiber polyester materials.
