Abstract:

In order to overcome the inherent defects of traditional fabric drape test method, a new testing method under the self-weight condition was proposed based on the three-dimensional shape of the human body, and a new testing device which can directly reflect the  three dimensional drape shape of fabrics was developed. The device was used to measure the number of corrugations, the drape coefficient, the average bending index, the bending index and so on, and the simulation analysis of fabric drape form was characterized by CAD. Results show the drape coefficient is in positive correlation with drape for the new test method. The test number of corrugations is similar compared with the conventional test method, and the correlation is as high as 0.9. It is indicated that the new fabric three-dimensional drape test method can more realistically reflect the real drape and drape form, and the new built index system can better reflect the three-dimensional drape shape of fabrics.
