PROBLEM TO BE SOLVED: To strengthen binding of a fluororesin fiber yarn with a base fiber yarn and increase strength to water leakage of a fabric in a twisted union fabric of a fluororesin fiber yarn with a base fiber yarn such as cotton or hemp. SOLUTION: This twisted union fabric W twisting a fluororesin fiber yarn 1 with a base fiber yarn 2 having a melting point higher than the fluororesin fiber yarn 1. In the fabric, the twisted union fabric W is hot pressed at a temperature rather lower than a melting point of the fluororesin fiber yarn 1 to obtain a fabric wherein the base fiber yarn 2 is bonded with the fluororesin fiber 1 at their intersecting part.
