Abstract

The invention discloses a nano-silver colloidal solution, a preparation method for the nano-silver colloidal solution and application of the nano-silver colloidal solution. The preparation method includes the steps of mixing an anti-acarien active matter water solution with the mass volume concentration of 10g / L-80g / L with a silver salt water solution with the concentration of 0.01g / L-100g / L according to the volume ratio of 1:100-100:1, gradually dropping a certain volume of reducing agent water solution into the mixture while stirring the mixture at a constant speed at the temperature of 10DEG C-90DEG C, and stirring the mixture for 1-600min until complete reaction to achieve the nano-silver colloidal solution with the average grain diameter of 1-100nm. The preparation method has the advantages that due to the fact that anti-acarien active matter frequently used in anti-acarien textiles is used as a protective agent to prepare nano-silver, the nano-silver can achieve anti-bacterium and anti-acarien effects at the same time, and the preparation method is suitable for anti-bacterium and anti-acarien compound functional finishing for the textiles.

Description

technical field [0001] The invention relates to a nano material, a preparation method and an application thereof, in particular to a nano silver colloid solution applied to antibacterial and anti-mite treatment of textiles and a preparation method thereof. Background technique [0002] Textiles are recognized as a medium for the growth of microorganisms such as bacteria and fungi. Microbial communities in nature widely exist in the surrounding environment, and can multiply rapidly once encountering suitable humidity, nutrients and temperature. For most chemical fibers, because of its high water repellency, it has a high ability to resist microbial attack. Protein and cellulose fibers can provide nutrients and a suitable temperature and humidity environment for microbial growth, becoming an ideal place for microbial growth. Microorganisms growing on textiles not only affect the performance of textiles themselves, but also affect the health of users. Therefore, how to suppr...
