PROBLEM TO BE SOLVED: To provide a knitted fabric containing an elastic yarn, which has a temperature rising instantaneously upon elongation, permanently generates heat upon elongation when the knitted fabric undergoes repeated elongation and recovery, facilitates a wearing operation, and is capable of being manufactured at low cost.SOLUTION: A knitted fabric includes an elastic yarn and a non-elastic yarn. The content of the elastic yarn is 15-50 g/m. The instantaneous exothermic temperature upon elongation in at least one of warp and weft directions is 1.0°C or greater. The filling rate of the knitted fabric determined by the following formula is 20-30%. The stress ratio determined by the following formula from an approach route stress and a return route stress at an intermediate point of 50% elongation when the knitted fabric is elongated to 80% and then returned to an original length is 0.40-0.80. The filling rate (%)=(M/L)÷(H1×K1+H2×K2+...Hn×Kn)×100 stress ratio=(a return route stress at a point of 50% elongation (N))/(an approach route stress at a point of 50% elongation(N)). |
