The nonwoven foundation for additional strength which possesses the strengthening fiber thread sheet

摘要

PPROBLEM TO BE SOLVED: To provide a nonwoven base fabric for reinforcement which does not cause problems such as opening of the mesh even if stitched and formed with a stitching thread. PSOLUTION: The nonwoven base fabric for reinforcement is formed by: keeping a sheet of reinforcing fiber filaments, consisting of reinforcing fiber filaments 1 nearly parallelly arrayed, and an auxiliary fiber material 2, that is stacked on the sheet so as to make an angle to the array direction of the reinforcing fiber filaments, retained in shape by stitching threads; and bonding the auxiliary fiber material with the sheet of the reinforcing fiber filaments.
