What are the soft properties of soft laundry detergent?

The hardening of clothes after washing is generally considered to be the formation of a salt film on the fibers, which cannot be washed off even during the rinsing process and adheres to the fabric. Laundry powder manufacturers add fabric softeners to prevent salt deposition on the fiber surface to form a salt film. In order to effectively prevent the function of salt film, the softener is required to have the following properties: ①Easy to disperse in water; ②It has a proper affinity for the object to be washed, and there is residual adsorption after washing; ③It is easy to disperse in the rinse solution; ④ It can give the fiber soft and fluffy properties (handfeel). To this end, it is necessary to reduce the friction between fibers, increase the lubricating feeling, and not produce an oily feeling; ⑤It can make the fibers have antistatic effect; ⑥It does not affect the color of the fabric. Even if the original color is not darkened, the effect of increasing the sense of lightness can be shown as much as possible; ⑦The treated fabric does not lose its easy wettability. Washing powder manufacturer. The most important varieties of fabric softeners are cationic quaternary ammonium salts, the representative ones are: dialkyl dimethyl quaternary ammonium salts, diamido-alkoxy quaternary ammonium salts, imidazoline compounds, alkyl dimethyl ammonium salts Benzyl quaternary ammonium salt, etc. Amphoteric surfactants, nonionic surfactants, and anionic surfactants also have softening effects. Its soft and antistatic properties are generally not as good as that of cations, so it is not as important as cations to use as a soft antistatic agent.
