The parameters of textile coating emulsion include appearance, viscosity, solid content, pH value, glass transition temperature (Tg), storage temperature and shelf life, etc. These parameters are crucial for evaluating the performance and application conditions of the emulsion. The following are some specific parameter descriptions:

Appearance: The emulsion can be a milky white slightly blue phase liquid or a light yellow liquid, depending on the specific type and composition of the emulsion.

Viscosity: Viscosity is an indicator for measuring the fluidity of emulsions. Different types of emulsions have different viscosity ranges. For example, the viscosity of the textile emulsion PA-510 is less than 500 mPa·s, while the viscosity range of the vinyl acetate-ethylene copolymer emulsion is between 1000 and 1500 mPa·s.

Solid content: Solid content refers to the proportion of solid components in an emulsion, expressed as a percentage. For example, the solid content of the textile emulsion PA-510 is 45±1%.

pH value: The pH value reflects the acidic or alkaline properties of the emulsion. Different emulsions have different pH value ranges. For instance, the pH value of high-elasticity waterborne acrylic emulsion is between 7 and 8, while that of silicone emulsion is between 6 and 8.

Glass transition temperature (Tg) : The glass transition temperature is the temperature at which a material transitions from the glassy state to the rubbery state. Different emulsions have different glass transition temperatures. For example, the glass transition temperature of the textile emulsion PA-510 is -16℃.

Storage temperature: Emulsions should be stored within a specific temperature range to maintain their performance. For instance, the storage temperature for highly elastic waterborne acrylic emulsions is 5 to 40 degrees Celsius.

Shelf life: The shelf life of an emulsion refers to the length of time it can maintain its performance under specific conditions. For instance, the shelf life of a highly elastic water-based acrylic emulsion is 9 months.

These parameters jointly determine the application performance and usage conditions of the emulsion, which is crucial for choosing an emulsion suitable for a specific purpose
