Sol–gel coating processing optimization for natural fibres; pp. 467–472

Zane Zelca, Svetlana Vihodceva, Silvija Kukle

Functionality of natural fibres can be enhanced by sol–gel technology. The sol–gel process has to be adapted with regard to the type of coated fibres and to the applied sol. In this research, pure cotton and hemp fibres were modified by the sol–gel technology with different processing parameters. The morphology of coating depending on the dipping time and sol composition, were studied by scanning electron microscopy (SEM). The aim of this research was to study the influence of different processing parameters of sol–gel methods like dipping time, the influence of sol compositions on the coating morphology and quality, and to obtain durable and smooth coatings for surface modification of natural fibres.
