Underbody knitted fabric product having a heat-ray prevention function

PROBLEM TO BE SOLVED: To provide a knitted fabric product for underbody, which has run-preventing function, is capable of efficiently and effectively preventing a run, further has good flexibility and aesthetic property as the knitted fabric for underbody, and uses a conjugate yarn. SOLUTION: The knitted fabric product for underbody, which has run-preventing function, is knitted by using a heat-fusible conjugate yarn, and if required, other yarns and includes a heat-fusible conjugate yarn-containing knitted fabric provided by fuse-bonding the heat-fusible conjugate yarns each other and/or the heat-fusible conjugate yarns with the other yarns at intersections, wherein the elongation at break of the heat-fusible conjugate yarn is ≥170%, and the residual strain at 50% elongation is ≤12%.
