Abstract:

In order to improve the abdominal effect of stomach lift supporting belt and the wear feeling of pregnant women, a suitable stomach lift supporting belt for the psychological and physiological needs of pregnant women was designed. The hip joint angle of pregnant women was taken as the research object. The relevant data were collected by three-dimensional motion capture instrument, and analyzed the factors which affecting the hip joint angle. The measured data were subjected to single factor analysis of variance test, and combined with subjective evaluation for comprehensive analysis. The data analysis shows that with the increase of gestational weeks and abdominal circumference, the hip joint angle of pregnant women in activity will also increase. The stomach lift supporting belt gives full play to the advantages of knitted tissue structure. When pregnant women are dressed, it can improve the belly lifting effect, play a role of stability and support, effectively reduce the hip joint angle of pregnant women, and thus play a good effect of abdominal effect. Moreover, it can improve the decoration and permeability of the stomach lift supporting belt by using the loop transfer structure, and improve the dress experience of pregnant women.

Key words: stomach lift supporting belt, abdominal effect, hip joint angle, knitted structure
