Therefore, they can be easily laminated and integrated by making use of the heat fusion properties of the nonwoven fabric and mesh cloth and bonding them under heat. Therefore, since it is not necessary to apply an adhesive over the entire surface or to form a hot melt adhesive layer over the entire surface, the air permeability inherent to the nonwoven fabric or mesh cloth is not impaired. In addition, the middle layer of the multilayer flat yarn 5 or the monofilament 5 with a core-sheath structure
By forming the core with the high melting point component 4, the nonwoven fabric laminate material maintains high strength.
