a first foundation fabric having on its one surface a number of raised interlocking elements and a second foundation fabric having weft threads of monofilaments are woven or knitted integrally with each other by means of connecting threads . the first and second foundation fabrics are firmly and integrally united together by a synthetic resin layer to form a surface - type fastener having a thick foundation fabric . the surface - type fastener of the foregoing construction does not require a conventional sewing process , can therefore be produced efficiently , can readily be rolled up on a reel , obviates the need for a complicated inventory management which would occur when the first and second foundation fabrics are stocked separately in view of the dimensions and colors of the respective foundation fabrics , is able to prevent the first and second foundation fabrics from separating during use of the surface - type fastener , and hence continuously maintains the necessary strength throughout the service life .
