摘要：

为优化蔗糖聚酯的乳化工艺，提高其乳液的稳定性，采用转相乳化法，研究了复合乳化剂HLB值、用量、油水比例、乳化时间、乳化温度及搅拌速度对蔗糖聚酯乳化效果的影响，并对蔗糖聚酯乳液的稳定性和应用性进行了研究。结果表明，最佳的乳化条件为：复合乳化剂HLB值为9.8，用量为9%，乳化水油比例为2，乳化时间85 min，乳化温度30 ℃，剪切速率2000 r/min；该蔗糖聚酯乳液具有高稳定性和良好分散性，粒径分布均匀，长期放置不分层，且该蔗糖聚酯乳液能够有效降低织物表面摩擦因数，赋予织物良好的柔软效果，对织物色变影响较小。

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
