Treatment of Timber by Nanofiber Fabric with Biocide Compound

Abstract

Dry rot fungus (Serpula lacrymans) is wood-decaying fungus. It grows frequently in our territory and it causes big damages on structures. Remediation of damaged structures is very difficult, sometimes impossible, therefore it is necessary to study preventive protection against dry rot fungus. PVA nanofibred fabrics with synthetic and natural biocidal additives were used for this experiment. Filter papers soaked in dopes with biocidal substances were other materials used for this experiment. Pieces of nanofiber fabrics and pieces of filter papers soaked in dopes were placed to Petri dishes with broth. Small cuts of dry rot fungus were placed around them. This experiment was performed in conditions, which promote the growth of dry rot fungus. Growth of dry rot fungus was studied.
