The Interactions Between Ease Variation Of Fitted Pants And Fabric Extensibility Based On Movement Comfortability

The interactions between ease variation of fitted pants and fabric extensibility based on movement comfortability was studied this paper. Twenty-one fabrics used for making pants were selected and classified into four catagories according to fabric basic parameters and extensibility, and one fabric was picked up from each of the four catagories. Then each fabric was made into three pants according to three different kinds of ease. The pressure comfort of the twelve fitted pants was subjectively evaluated and objectively tested by using AMI clothing pressure tester during wear trials. The results of cooperation coefficient Kendall's W test showed that five subject's results were effective and under the same evaluation criterion. Correlation analysis was carried out to analyze the relationship between the subjective values and the objective test values obtained in the wear trials. It was found that there were significant correlationship between the subjective values and the objective test values at body parts such as abdomen, thigh, knee, thigh and buttocks; there was correlationship between the subjective values and the objective test values at shank. Meanwhile, regression equation was obtained by using regression analysis to the subjective values and objective values.The pressure comfort from the aspect of fabric extensibility and ease variation were studied in this paper. According to the influence of fabric extendibity to fitted pants'pressure comfort, the pressure comfort was the best when the human body to take the posture of standing and walking; the pressure comfort of bdomen, buttocks, thigh were the worst when the human body take the posture of sitting, squatting, and lift the leg. Therefore, when carrying out structural design of fitted pants, full consideration of skin deformation rate of the abdomen, buttocks and thigh when the body take the posture of sitting, squatting, and lift the leg to meet the needs of pressure comfort must be considered. From the analysis results of fabric extensibility and pressure comfort, the use of experimental version of type B and type C version of the fitted pants can basically meet the needs of the lower extremity pressure comfort when the fabric elongation of warp direction more than 23.7%, elongation of weft direction more than 50.6%. Meanwhile, correlation analysis showed that the correlation between the pressure tests in different parts of the objective value and the wrap elongation was not significant, and the correlation between the objective values and the weft elongation was significantly.Besides, the paper analyzed the relationship between the ease variation of fitted pants and pressure comfort. For The fabric NO.1, there was no ease variation in this essay to fully satisfied the moving comfort of the body; to fully meet the pressure comfort of pants made of fabric No.1, then the required amount must be greater than C edition. For the fabric NO.2 and NO.3, the ease variation to meet the pressure comfort were as followings:Waist=1cm, Hip=6cm, the crotch depth=3cm, Knee=3cm, calf circumference=3cm, thigh circumference=3cm. For the fabric NO.4, he ease variation to meet the pressure comfort were as followings:Waist=1cm, Hip=2cm, the crotch depth=1cm, Knee=1cm, calf circumference=1cm, thigh circumference=1cm. Calf circumference, wrap elongation and weft elongation were the three factors which influence th pressure comfort of fitted pants.
