Female engaging member of surface fastener and production apparatus thereof

A female engaging member of a surface fastener comprised of a flat plate-like substrate having a first surface and a second surface and a multiplicity of pile-like engaging elements on the first surface, and adapted to be in a plane contact with a mating male engaging member of the surface fastener, wherein

• said pile-like engaging elements are comprised of rows of multifilament entangled yarns having a multiplicity of loops on surfaces thereof,
• a multiplicity of parallel elevated portions are disposed on the first surface of said flat plate-like substrate in a width direction thereof, and
• said entangled yarns are disposed on said first surface perpendicular to said elevated portion and said entangled yarns are integrally fixed to said elevated portions at crossing portions therebetween.

A female engaging member of a surface fastener having a multiplicity of pile-like engaging elements on a first surface of a flat plate-like substrate and adapted to be in a plane contact with a mating engaging member of the surface fastener, wherein

• said pile-like engaging elements are comprised of multifilament entangled yarns having a multiplicity of loops on surfaces thereof,
• through holes are formed in said flat plate-like substrate in a matrix and a multiplicity of said entangled yarns are disposed along each row of the through holes arranged in a length direction of the first surface, and
• an adhesive agent layer is formed on a second surface on an opposite side to said first surface of said flat plate-like substrate so that component adhesive agent of the adhesive agent layer is fused integrally with said entangled yarns locally through said through holes.
