Abstract: Experiments were designed according to the human body curve line,wear-comfort of the darts and stitches,and to the traditional ironing technique under corresponding temperature,humidity,pressure,time and the cooling way.Ironing was applied to 11 kinds of apparel fabrics of natural,synthetic,and blended fibers based on the corresponding design of body measurements,and the results were analyzed.It revealed that as with the natural fiber fabric,owning to its good properties,good effect of stretching and shrinking could be obtained as long as controlling the basic parameters well in the test.The change in fabric length also affected the space volume of stretching and shrinking,which showed that the natural fabric has better performance in meeting the body 3-dimensional fitting needs after stretching and shrinking.The synthetic fabric has good elasticity,poor hydroscopicity,and small yarn to yarn friction coefficient,shape keeping time is short after pushing,stretching and shrinking.Therefore,it will get better effect if increasing all the technique parameters during the ironing process.The blended fabric has the virtues of both natural and synthetic fibers,and it has good shape keeping property.However,the volume of stretching and shrinking when ironing depends on the human anatomy and muscles.
