Abstract

Sliver nanocolloids have been synthesized by chemical reduction of sliver salt solution, characterized by SEM usage of nanoparticles. Sliver nanocolloids are treated with wool fibres and dyed wool fibres (direct and acid dyes). The physical properties, colour strength, and fastness properties have been studied for dyed wool fibres and ordinary wool fibres. It is observed that the fibres with nanotreated fibres have better strength than untreated wool fibres. It is also observed that there is considerable improvement in colour strength and colour fastness of silver nanocolloids-treated wool fibres (dyed).

Highlights

During the past two decades, the small-particle research has became quite popular in various fields of chemistry and physics
The nanosilver particles because of their small size can enter in between the molecules and perhaps act as filler or crosslinking agent which contributes to the load sharing phenomenon during load application to the material
Unlike chemical crosslinking which causes an improvement in crease recovery angle at the cost of imparting some rigidity in the material to an extent depending on the extent of crosslinking, the incorporation of nanosilver particles remains quite gentle in this regard

Summary

Introduction

During the past two decades, the small-particle research has became quite popular in various fields of chemistry and physics. Metallic nanoparticles represent a class of materials that are increasingly receiving attention as important starting points for the generation of micro-and nanostructures These particles are under active research because they posses interesting physical properties differing considerably from that of the bulk phase. It has small sizes and high surface/volume ratio. The findings support the view that the cell membrane complex and other low sulphur regions are the main route of entry for both molecular and macromolecular treatment chemicals The use of this technique to treat wool may lead to new coloration effects and other functions such as antimicrobial action [4–14]
