Claims
- 1. A separable fastener comprising a base part and a multiplicity of engaging elements raised from the obverse side of said base part, said base part having at least a portion formed by a molded plate, said molded plate of said base part defining a recess extending from an outer surface of said base part into said base part, said base part and said engaging elements being formed of a biodegradable resin.
- 2. The separable fastener according to claim 1, wherein at least said base part has a cross-sectional shape such as to give a large specific surface area to said base part.
- 3. The separable fastener according to claim 1, which comprises holes formed in at least said base part.
- 4. The separable fastener according to claim 3, wherein said holes are formed by molding with a die.
- 5. The separable fastener according to claim 3, wherein said holes are formed by the dissolution of a water-soluble resin.
- 6. The separable fastener according to claim 5, wherein said water-soluble resin is selected from the group consisting of polyvinyl alcohol, modified polyvinyl alcohol, polyacrylic acid, polyethylene oxide, carboxymethylcellulose, and gum.
- 7. The separable fastener according to claim 3, wherein said holes are extended from the reverse side of said base part through the interiors of said engaging elements.
- 8. The separable fastener according to claim 1, wherein said base part has a plurality of grooves extending in the longitudinal direction thereof.
- 9. The separable fastener according to claim 1, wherein said base part has a plurality of grooves extending in the lateral direction thereof.
- 10. The separable fastener according to claim 1, wherein said base part is a fabric having a back coating layer of a water-soluble resin.
- 11. The separable fastener according to claim 10, wherein said water-soluble resin is selected from the group consisting of polyvinyl alcohol, modified polyvinyl alcohol, polyacrylic acid, polyethylene oxide, carboxymethylcellulose, and gum.
- 12. The separable fastener according to claim 1, which comprises grooves formed in at least said base part.
- 13. The separable fastener according to claim 12, wherein said grooves are formed by molding with a die.
- 14. The separable fastener according to claim 12, wherein said grooves are formed by the dissolution of a water-soluble resin.
- 15. The separable fastener according to claim 1, wherein said base part is a fabric having a back coating layer of a biodegradable resin.
- 16. The separable fastener according to claim 1, wherein said base part is formed entirely by said molded plate.
- 17. The separable fastener according to claim 1, wherein said base part further comprises a woven portion attached to said molded plate.
- 18. The separable fastener according to claim 1, wherein said biodegradable resin is selected from the group consisting of a copolymer of hydroxybutyric acid with hydroxyvaleric acid, a blend of starch with modified polyvinyl alcohol, a blend of starch with a biodegradable synthetic polymer, an aliphatic polyester, polycaprolactone, and polylactic acid.
