Application of method iodine sorption value (ISV) for monitoring of cecondary washing effect

Water as a medium in which to wash, also serves as a solvent for water-soluble dirt and most of the ingredients of detergent. Removed dirt from textiles remain in the bath for washing, and textiles for some time to wash greasy bath, and this is particularly true in the washing machines. It is necessary to keep the dirt in the bath and to prevent their re-deposition on the fibers which would cause graying of textiles. The secondary effect of the money is a result of the cumulative effect of a large number of the most frequently wash textiles. The intensity changes of textiles in the wash depends on the initial quality, and process conditions, temperature, composition of detergents, alkalinity, mechanical parameters, the number of cycles and so on. The tests are provide on cotton cellulose. The degree of degradation of cotton cellulose depends on the degree of polymerization, the construction characteristics of textiles, bath composition for washing, alkalinity, temperature, mechanical influences, the way of drying and ironing. This paper examined the acceptability of methods of determining the sorption of iodine for determining changes resulting from multiple washing cycles. Fabrics were washed in the same bath in a continuous process in an industrial laundry through 3 and 100 cycles. On these fabrics are certain all quality control parameters according to HRN ISO 4312: 2001 (Surface active agents - Evaluation of certain effects of laundering - Methods of analysis and test for unsoiled cotton control cloth (ISO 4312:1989)).
