Surface fastener made of fiber and method for manufacturing the same

A method for manufacturing a surface fastener made of fiber including a large number of engaging elements which are woven/knitted simultaneously with weaving/knitting of a ground woven/knitted fabric formed of a ground structure and which project from a surface of the woven/knitted fabric,

• wherein all of the yarns constituting the ground structure and a yarn constituting the engaging elements are made of monofilament, said method comprising the steps of:
• (a) weaving or knitting monofilament which is constituting material of female and/or male engaging elements while forming loops on a surface of the ground woven/knitted fabric simultaneously with weaving/knitting of the ground woven/knitted fabric by using the yarns made of monofilament,
• (b) thermally setting the completed woven/knitted fabric to fix a weaving/knitting shape,
• (c) coating synthetic resin material on a rear face of the set woven/knitted fabric to form a thin film,
• (d) spraying air on the film in a direction from the rear face side to a front face side of the woven/knitted fabric to concentrate the film on crossings of respective constituting yarns of the woven/knitted fabric, and
• (e) forming gaps by the concentration of the film through the surface fastener in a direction from the front face to the rear face between the respective constituting yarns.
