SHEET OF NATURAL COCONUT FIBER FOR IMPROVING QUALITY OF WATER

PROBLEM TO BE SOLVED: To solve such a problem that, although a method for winding a sheet of a natural coconut fiber to prepare a vegetation roll, arranging the vegetation roll at a water's edge, staking the arranged vegetation roll and bedding out a plant on the vegetation roll is said to be the most suitable for fitting a slope at the water's edge to the natural environment, the vegetation roll is not suitable as a residence of the plant when the quality of water is bad, and although there is a case that water is purified by using charcoal, this case is not adopted as a natural environment positively protecting means for activating the quality of water, and such another problem that the contact surface of the vegetation roll with water is apt to get moldy and slippery so that the water permeability of the vegetation roll is deteriorated. SOLUTION: Powder of olivine generating far infrared rays is sprayed or applied to the sheet of the natural coconut fiber, which is then used as the vegetation roll. In order to assist photosynthesis in the water, powder of titanium oxide is stuck to the sheet of the natural coconut fiber, which is then used as the vegetation roll. When these vegetation rolls are used, the quality of water can be improved. COPYRIGHT: (C)2005,JPO&NCIPI
