ABSTRACT:
Disclosed are a biodegradable separable fastener which can be appropriately used as a fastening means for disposable products and a method for the production thereof. In a separable fastener composed of a base part and a multiplicity of engaging elements raised from the obverse side of the base part, the base part and the engaging elements are formed of a biodegradable resin. In a favorable mode, at least the base part of the separable fastener has such a sectional shape as to increase the specific surface area. For example, grooves and/or holes are formed in the base part or holes are extended from the reverse side of the base part to the interiors of the engaging elements. The biodegradable separable fastener having such grooves and/or the holes may be manufactured by forming at least part of the base part with a water-soluble resin and the other part of the fastener with a biodegradable resin and, after the manufacture of the separable fastener, causing the water-soluble resin to dissolve out into a solvent.
