Hazards of Using Hard Water for Hotel Linen Washing1

Calcium and magnesium ions in hard water are deposited on the fabric, causing graying of the white fabric, affecting the whiteness and hand feel, darkening the color of the colored fabric, losing the bright feeling, and rough hand. Iron exists in water in the form of ions or ionic compounds. If these waters are heated to wash fabrics, rust will be formed, deposited on the fabrics as some brown spots, and will also turn white fabrics overall yellow and bright-colored fabrics. In addition, the water contains iron. In the bleaching stage, if iron ions exist in a certain part of the fabric, it will catalyze the strong decomposition of hypochlorite or hydrogen peroxide, causing the local oxidation reaction to be violent and causing the fabric to be damaged.
2. The effective function of the detergent is reduced
Calcium and magnesium ions in hard water combine with surfactants in detergents, which can form metal salts, lose the activity of surfactants, and cannot perform the proper performance of detergents, reducing the main functions of detergents.
3. Can not completely remove the dirt on the fabric
Calcium and magnesium ions in water can combine with substances in detergents to form precipitates. Calcium ions will make some dirt still adhere to the clothes after washing, drill into the fiber pores and capillaries, hide in the fiber gaps, and affect the removal of colored dirt.
