Comparison of chemical wear of standard cotton cloth after laundering using different solvents for cellulose

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 in cotton cloth is caused by the action of chemical agents during the laundering process and leads to changes in the intrinsic properties of the fibres. The consequence of chemical wear is the reduction in the degree of polymerization of the cellulose constituent. In our research we investigated the influence of oxidising agents on the chemical wear of test cotton fabrics (DIN 53919) laundered in different industrial and hospital laundries. Different standard solvents for cellulose: copper tetra-amine hydroxide, copper (II) ethylene-diamine and iron (III) tartaric acid sodium complex were applied in the inter-laboratory testing. The results show that all three methods are equivalent since the results obtained are relatively comparable.
