Abstract
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.
