Abstract: To maintain integrity of the pattern and meet the needs of fitness,the influence of the fabric heat setting on model method of Chinese gown was analyzed.First of all,it was designed that the structure and the blocking process of fitness of no-dart Chinese gown according to the structure of human body and the influencing factors of synthetic fiber heating setting and blocking performance of fabrics were discussed.Then the fabric content,identifies individual material and plans for the test were analyzed,the blocking performance of the fabric was tested and the test data was analyzed through mathematic method to find out the relationship among different factors and the best combination parameters.Finally,no-dart Chinese gown will be produced on trial basis by adopting the best combination parameters.The study shows that by taking advantages of thermoplasticity of synthetic fabrics and combing with the features of the human body and garment structure,it is possible to design blocking first and then cutting model for making fit and no-dart Chinese gown.
