Study on preparation and soft application on cotton of sucrose polyester emulsion

The factors affecting stability of sucrose polyester emulsion such as emulsification method,the HLB value and dosage of compounded emulsifier,emulsification temperature and the type and dosage of thickener are investigated and thus the optimum technological parameter is obtained.The application properties of the cotton fabric finished with sucrose polyester is tested,compared with 3 different softeners in market.The results indicate that when emulsification method is inverse emulsion method and the HLB value and dosage of compounded emulsifier are 10.4 and 6%,and emulsification temperature and the type of thickener are 90 ℃ and synthetic thickeners PTF,the stability of sucrose polyester emulsion is the optimum,and the cotton fabric finished with sucrose polyester as good soft as fatty acid amide TF-449B,much softer than modified fat hydrocarbon TF-564 and not softer than organic silicon softener TF-432B.
