ABSTRACT OF THE DISCLOSURE A knitted material is disclosed having on one side a multi- plicity of upstanding hook-like engaging elements suitable for repeated face-to-face engagement and disengagement with a material having a multiplicity of upstanding pile loop-like mating engaging elements. The material has a base knitted fabric and a plurality of upstanding monofilamentary members inter- knitted into the base fabric, with a hook-like engaging element positioned at the upper end of each upstanding member. The en- gaging element extends transversely of the upstanding member and is configured in cross section to have at least one end generally arcuate in shape and the opposite end tapered. The tapered end has greater flexibility than the arcuate end, and the fastener fabric is engageable in face-to-face relation with a mating loop- type fastener fabric and separated by forces normal to the inter- facial plane of engagement. A method and weft-knitting apparatus for producing the unique knitted fabric are also disclosed.
