<p>An elastic fabric is formed by applying an elastic yarn to the fabric in a manner where the elastic yarn is in continue in either length direction (h) of the fabric or width direction (r) of the fabric. (.) stress at 10% elongation of the fabric is set up 150 &tilde& 600N/5cm in the direction (X) where the elastic yarn is in continuous. (.) stress at 10% elongation (B;N/5cm) in the 45 degrees bias direction (Z), where has an inclination of 45 degrees to the prolonging direction (X), is set up 5 &tilde& 20 % of stress at 10% elongation (F;N/5cm) in the prolonging direction (X) of the elastic yarns. (.) a rate of hysteresis loss DELTA E in the prolonging direction (X) of the fabric is set up 20 &tilde& 45%. <??>When the elastic fabric is hanged over a frame, an elastic top material which is smallsized, easy to deal with, light weight not bulky, and limbs may be supported in stable can be obtained. <??>Yarns of which breaking elongation is more than 60 % and rate of an elastic recovery after 15 % elongation is more than 90 % are used for the elastic yarn. <IMAGE></p> |
