Sažetak
The objective of laundering is to return soiled textiles to a clean, hygienic and ready-for-use state with minimal damage influenced by chemical and mechanical action. Chemical wear of the cellulose is caused by the action of chemical agents during the laundering process and leads to changes in the intrinsic properties of the fibres. Chemical damage is mainly caused by oxidizing bleaching agents and is often intensified by the presence of heavy metal ions and also by alkalis. The consequence of chemical wear is the reduction in the polymerization degree of the cellulose constituent. Therefore it is important to determine the chemical wear of individual laundering procedures. In our research we investigated the influence of oxidising agents on the chemical wear of test cotton fabrics (DIN 53919-1) laundered in different industrial and hospital laundries. Different standard solvents for cellulose: ammonium copper (II) hydroxide – CUEN, copper tetra-amine hydroxide – CUOXAM and iron (III) tartaric acid sodium complex – EWN were applied in the interlaboratory testing. The results show that all three methods are equivalent since the results obtained are relatively comparable.
