Wet cleaning. Fabric baths can be carried out in cold or warm water with or without cleaning additives. Washing in a water solution of washing agents is used depending on the type of fabric and its condition. Bathing in an alkaline environment (cationic), sour (anionic) relatively non-ionic or mixed (e.g.. non-ionic first, and then cationic) must be appropriately selected for the type of fibres, react differently to these aqueous solutions.
In washing fabrics in aqueous solutions, movement plays a role in addition to the detergent, temperature and pH value of the bath.
The influence of mechanical movements. Agitation of the fabric in the washing bath makes it easier to free it from dirt. However, the type of these movements should depend on the type of fibers, their behavior. Under no circumstances should an old fabric be washed in a washing machine. With stronger movements during washing materials, e.g.. wool, they overlap and converge. Often the bath should be limited to immersion in the washing liquid and repeated stirring movements. Old fabrics in a wet state show less resistance than dry ones, therefore, during washing, they usually require reinforcement in the form of a primer, e.g.. made of fabric or nylon mesh. The backing under the fabric allows you to move it during the bath and extract it from the washing liquid. In order to achieve greater washing efficiency, the fabric is sometimes stitched with a sponge, so that the washing liquid is squeezed out and sucked. The basic principle of washing is to minimize the mechanical load on the fabric. Placing it on a table for this activity with the stretched plastic wrap raised at the edges helps, forming a flat tub.
