Adjustment of clothing pressure for compression wear is critical to the physiological and psychological satisfaction of the wearer; however, there are limited studies on the practical relationship among extensibility of materials, pattern reduction of compression wear and resultant clothing pressure. This study provides consumers and designers with information on clothing pressure using a screening extensibility test suggested by Ziegert and Keil (1988) even for the final products. As the first step, ten commercial products were collected and their size, extensibility and corresponding clothing pressure were analyzed. It was found that clothing pressure around the waist level could be predicted well from the information of Ziegert and Keil's (1988) % extensibility of the material (Z stretch %) and the actual application of Z stretch amount to the pattern reduction rate (applied % of Z stretch), with an $r^2$ of around 0.80, especially at the waist level. However, it was not simple for the case of clothing pressure around the back of the chest level due to the various design variation and the complexity of the anatomical structure around the trapezius.

Recently, because the market for compression wear now includes all consumers, not just professionals, various items for recovery after exercising or for enhanced effects from exercise have been introduced. In this research, a systematic and stepwise design process was proposed to develop compression garment that has both functional area and appropriate pressure to protect the knee when exercising. The U-V format functional area that wraps underneath the knee was selected by considering the shape and change in the skin length when bending the knee. After the selection of the functional area, a total of seven knee design areas, including the existing product, were designed to determine the appropriate pressure. After various movements, the compression garment was ranked in terms of support of the knee, level of pressure, discomfort of seam line, and comfort of popliteal; the preferred design was selected using the quad method. Four compression wear garments were produced using two selected preferred designs; the wear evaluation was performed using a seven-point Likert scale. As a result, the optimal reduction rate of the pattern was calculated based on Ziegert and Keil's method. The applied percentage of the fabric stretch at the upper part of the crotch was 66% for the width and 50% for the length; for the lower part of the crotch, only 66% for the width was applied. Moreover, it was determined that the design of the U-V knee protection part was preferred when a 7 mm square was placed at a 1 mm distance because this not only supports the knee but also allows the fabric to accommodate various skin deformations.
