ELASTIC KNITTED FABRIC AND CLOTHING ITEM

摘要

An elastic knitted fabric comprising an elastic yarn and a non-elastic yarn, the elastic knitted fabric being characterized in that: the elastic yarn content is 20-60 g/m2; when the knitted fabric is stretched to 80% and then returned to the original length and the forward-movement stress and the return-movement stress at the 50% point during the stretching and contracting are measured, the stress ratio measured using the following relationship: stress ratio=(return-movement stress (N) at the 50% point)/(forward-movement stress (N) at the 50% point) is 0.40-0.80; and the instantaneous temperature rise caused by heat generation during stretching in the warp and/or weft direction is at least 1.0° C.

1. An elastic knitted fabric comprising an elastic yarn and a non-elastic yarn, wherein the content of the elastic yarn is 20 g/m2 to 60 g/m2, the stress ratio, as determined according to the following equation when the stretching stress and the stress of elastic recovery are measured at 50% elongation during stretching and recovery after having stretched the knitted fabric to 80% elongation followed by returning to its original length, is 0.40 to 0.80, and the instantaneous temperature rise caused by heat generation during stretching in at least the warp or weft direction is 1.0° C. or more.
Stress ratio=(stress of elastic recovery (N) at 50% elongation)/(stretching stress (N) at 50% elongation)
