PAPER STRING HAVING WATER RESISTANCE AND SUPPORTING TOOL FOR CULTIVATING PLANT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a paper string excellent in water and weather resistances and biodegradability and suitable for cultivating a plant without requiring removing and recovering operations and to provide a netlike supporting tool for cultivating the plant producible by knitting in or heat-seal joining using the paper string and excellent in the water and weather resistances and biodegradability without requiring the removing and recovering operations. ;SOLUTION: This paper string having water resistance is obtained by twisting a blend paper of biodegradable thermoplastic synthetic staple fibers comprising 20-90 wt.% of the biodegradable thermoplastic synthetic staple fibers and 10-80 wt.% of vegetable fibers for papermaking and having 15-80 g/m2 basis weight or a combination paper prepared by joining a layer containing the biodegradable thermoplastic synthetic staple fibers to at least one surface of a layer without containing the biodegradable thermoplastic synthetic staple fibers according to the combination and having 15-80 g/m2 basis weight. Furthermore, the netlike supporting tool for cultivating a plant is obtained by weaving the paper string or crossing the paper string without weaving and thermally fusing the interlaced parts or knitting the paper string therein.;COPYRIGHT: (C)2000,JPO
