た。Next, the three-dimensional structure knitted fabric is impregnated with a urethane resin having a viscosity of 5 to 30 poises, excess resin is removed by mangle or the like, and then solidified, so that the connecting thread resin adhesion amount is 15% of the total resin adhesion amount of the three-dimensional resin molded product. %, 20%, and 25% solid resin moldings were obtained. The resin adhesion amount at this time was 60% by weight.
