Description
Technical Field
The invention relates to the technical field of spinning, in particular to a preparation method of an emulsifier for anti-freezing spinning sizing.
Background
Emulsifiers are substances which enable a mixed liquid of two or more components which are not compatible with each other to form a stable emulsion. The principle of action is that during emulsification, the dispersed phase is dispersed in the continuous phase in the form of droplets (micron-sized), the emulsifier reduces the interfacial tension of the components in the mixed system, and forms a stronger film on the surface of the droplets or an electric double layer on the surface of the droplets due to the charges given by the emulsifier, preventing the droplets from aggregating with each other, and maintaining a uniform emulsion. To express hydrophilicity or lipophilicity of an emulsifier, "hydrophilic-lipophilic balance (HLB value)", the lower the HLB value, the more lipophilic it is; conversely, the higher the HLB value, the more hydrophilic it is. The HLB values of the various emulsifiers vary, and in order to obtain a stable emulsion, the appropriate emulsifier must be selected.
The special emulsifying agent for spinning in the current market is generally a cationic surfactant, has weak hydrophilicity, is suitable for W/O type emulsion, has obvious limitation, is easy to layer and cannot realize the emulsifying effect rapidly when the external temperature is reduced, and has low efficiency.
