Application of Vacuum Evaporation to Obtain Natural Fiber Textile Products Ultra Thin Metallic Coatings

By Silvija Kukle and Svetlana Vihodceva

Abstract

The fundamentals of nanotechnology lie in the fact that properties of substance considerably change when their size is reduced to the nanometer range. One of the main tasks of research is to impact the additional value on cotton fabrics by adding them new properties with a metal nano-level coating. Metal covered textiles have attracted a lot of attention in recent years due to their special surface properties, such as heat radiation resistance, antimicrobial and anti-fungicidal properties and chemical resistant properties. Although vacuum metallization proc┬Česses are at present the most commonly applied methods of obtaining thin me-tallic layers, they have not been used for coating natural textile material. The process of vacuum evaporation of copper layers on cotton knitted fabric is carried out. As it is very important to efficiently clean off all oils, waxes that are used in fabrics manufacturing process and dust and dirt particles to allow good interfacial contact between fabric surface and deposited metal, different material pretreatment processing methods are being investigated to find the most successful one
