研究目的
Investigating the effect of silver content in cotton fabric on the extent and duration of the antiseptic effect and the role of tannide fixation in enhancing these properties.
研究成果
The study found that durable antiseptic properties of various strength appear only after tannide fixation of the composition in the fabric structure. Tannides reduce the solubility of gelatin, leading to its deposition on the fiber surface and protecting silver particles from being washed out. The antiseptic effect depends on the amount of silver in the fabric, with biocidal action appearing at low silver content and being retained up to higher concentrations.
研究不足
The method determines elements within the material by calculation rather than direct experimental measurement, introducing certain error. The study also notes a limit to the total adsorption capacity of the fabric.
1：Experimental Design and Method Selection:
The study used laser spark spectrometry to evaluate the silver content in cotton fabric treated with silver hydrosol and tannides.
2：Sample Selection and Data Sources:
Cotton fabric samples were treated with various compositions of silver hydrosol and tannides.
3：List of Experimental Equipment and Materials:
LIéS-2 express elemental analyzer, silver hydrosol, tannides (quebraho wood tannides and mixed tannides), gelatin.
4：Experimental Procedures and Operational Workflow:
Fabric samples were treated with silver hydrosol and tannides, then analyzed for silver content before and after laundering.
5：Data Analysis Methods:
The silver content was quantitatively evaluated using laser spark spectrometry, and antiseptic properties were assessed through biocidal, bactericidal, and bacteriostatic tests.
