Professional detergents play a major role in washing and decontaminating. Usually classified by ion type when dissolved in water:
1. Cationic surfactant: After ionization in water, the active moiety is positively charged. It is an important part of softeners and antibacterial agents.
2. Anionic surfactant: After ionization in water, the active moiety is negatively charged. It is an important part of cotton fabric detergents.
3. Nonionic surfactant: not ionized in water, the active part is not charged. It is an important part of chemical fiber fabric detergent.
a. Wetting: The droplets spread on the surface of the solid to wet the surface, called the wetting of the liquid. The wetting effect of the professional detergent in the dry cleaning franchise is mainly to reduce the surface tension of the liquid, so that the washing liquid is adsorbed by the fabric and even penetrates into the fibers of the fabric.
b. Emulsification: Incompatible liquid, after adding a small amount of detergent, by external force, one of the liquids is dispersed in another liquid with very fine droplets and does not stratify for a long time, called emulsification. effect. The emulsification of the professional detergent in the dry cleaning franchise plays an important role in the oil stain on the washing fabric. The oil stain is washed out of the fabric and becomes an emulsified state, and is not easy to aggregate and precipitate on the fabric.
c. Dispersion: It can promote the pulverization of solid particles and the uniform dispersion in the liquid. Dry cleaning franchise professional detergent can make solid particles form a hydrophilic adsorption film, so that the solid particles are suspended in water, not easy to precipitate on the fabric, and drained with water.
d. Foam action: The formation of foam is mainly caused by the directional adsorption of the surfactant to reduce the tension of the gas-liquid two-phase interface. Its main function is to increase the ability of the detergent to carry dirt, so that the dirt is adhered by the foam and discharged together with the foam floating on the surface of the solution. However, too much foam in the professional detergent of the dry cleaning franchise will reduce the friction of the washing, which is not conducive to decontamination, and is not conducive to rinsing the fabric.
e. Solubilization: When the surfactant solution concentration reaches the critical concentration of micelles, the solubility of some oil-soluble soils in the detergent solution increases. This phenomenon is called solubilization. Solubilization is the ultimate stage of emulsification and dispersion. It plays an important role in the removal of oil from detergents.
