Abstract:

In order to optimize the emulsification technology of sucrose polyester and improve the stability of the emulsion, using inverse emulsion method, the experiment studied the effects of HLB value of composite emulsifier, dosage of emulsifier, ratio of oil/water, emulsifying time, emulsifying temperature and stir speed on the sucrose polyester emulsion, and researched the stability and application of sucrose polyester emulsion also. Results show that the best emulsifying conditions as follows: the HLB value of composite emulsifier is 9.8, the dosage is 9%, ratio of oil/water is 0.5, emulsifying time is 85min, emulsifying temperature is 30 ℃, and the stir speed is 2000r/min. The sucrose polyester emulsion has high stability, good dispersibility, uniform particle size distribution, and can be long-term storaged. The sucrose polyester emulsion can reduce surface friction coefficient, attaches the fabric good softness and less impact on color change.

Key words: sucrose polyester emulsion, emulsification, particle size distribution, soft effect
