Abstract: The method is applied that the superficial structure of lotus is imitated,on the one hand,it imitates the nipple rise of the micron structure of lotus,and on the other hand,it imitates the nanometer structure of lotus.The polyester superfine sea-island fiber with the linear density 160 dtex/48 f is selected to imitate the diameter of nipple rise;the crepe weave and the high-shrinkage polyester filament are used in the fabric to imitate the rise height of nipple.The nanometer structure of lotus is imitated with nanometer titanium dioxide.It is determined that the compound dispersing agent consist of the lauryl sodium and polyacrylic ammonium;when the proportion of lauryl sodium and polyacrylic ammonium is 1∶1 and the supersonic time is 10 min,the dispersion effect is quite ideal.Finally,the properties of the fabric with lotus-like surface are tested.The results show that the developed fabric has satisfying super hydrophobicity,basic moisture permeability and air permeability,better drape and wrinkle resistance,but luster isn′t very good.
