The foam dyeing process of fabrics, yellow, pink, orange, red...etc. The world is full of colors. As far as the textile industry is concerned, the importance of colors has increased a lot. In the world of textiles and clothing, color is one of the factors that attract customers. This makes fabric dyeing more important than other processes. The world of fabric dyeing has not forgotten the technological changes, so several new dyeing methods have been dyed. New fabrics, detergents, and environmental issues are some of the issues to keep in mind when developing new dyes in order to replace traditional and more harmful dyes.
Another important factor is that almost all products are affected by seasonal demand and changes. Industrial textile dyes must rise to meet all these new and specific technical requirements.
A supplement to the dyed fabric dyeing is the foam dyeing process. As the name suggests, in foam dyeing, the main dyeing element is foam. In foam dyeing, foam is obtained from an aqueous solution and then spread on a non-woven fabric. Carriers for blowing agents and dyes are also used in this process. After the fabric is covered by foam, the dyes can be well combined after high temperature.
An aqueous solution is any solution in which water is a solvent, that is, it has a large amount of water. Foam is a dispersion in liquid. The liquid here is generally water, and the gas is generally air, but it may also be an inert gas.
This process has more advantages than other processes because it involves treating the fabric with foam at low moisture absorption. Moisture absorption refers to the amount of finishing liquid applied to the fabric. There are basically two types of foam: dispersion foam and condensation foam. Dispersion is a heterogeneous system composed of dispersed phase and dispersion medium. In colloidal dispersions, one substance is dispersed into very fine particles in another substance called a dispersion medium. Condensation reactions involve the loss of small molecules such as water or hydrogen chloride from the reactants to form linkages.
