Abstract:In this paper, experimental research, mainly through the structure of different cotton fabrics with the ease at the top of sleeves, this experiment mainly related to set the ease at the cap of sleeves from the different structure of the cotton fabrics. Through experiments we can get the relationship between the fabric and the cap of sleeves,in order to provide a stable and reliable advice to the pattern-makers,so it can reduce the time of changes ,improve the accuracy and the degree of syncytial to make a pattern, saving the time of making patterns, thereby enhancing production efficiency.
