Abstract:

Change rate of inflation size of inflatable warm clothing directly affects the design and production of such products. In order to better grasp the relationship between the two, 6 different inflatable fabrics of the same laminating shape, with 30%, 50%, 70%, 100% different inflatable states, were tested, and the change rate of inflation size of these clothing models were evaluated in the warp and weft directions. The experimental results show that the amount of inflation and the change rate of inflation size have a strong positive correlation. For different fabrics with the same inflation, the warp change rate of inflation size rate is greater than the weft change rate of inflation size, and when the inflatable state reaches about 70%, the increase in the warp change rate of inflation size rate weakens, and the weft change rate of inflation size rate gradually becomes smaller. Through the analysis, the maximum warp and weft change rate of inflation size rates of the inflatable garment are obtained, which can be used as a design reference for the increase in the size required to increase the size of the inflatable garment in addition to the basic length and circumference. The change rate of inflation size was applied to the size design of the inflatable warm clothing sample according to the push layout release method.

Key words: inflatable clothing, warm clothing, inflation amount, change rate of size, clothing model
