FIBROUS-MASS PRODUCT, AND ARTIFICIAL SOIL USING FIBROUS-MASS PRODUCT

摘要

A fibrous-mass product is provided which has both water retentivity and strength, and in addition, good air permeability, and can be used as an artificial soil particle. A fibrous-mass product includes a core portion which is an aggregate of fibers, and a water permeable membrane which covers the core portion. The water permeable membrane has porous structure, and covers at least 40% of an outer surface portion of the core portion. The core portion has a water retention material. Ion exchange capability is imparted to at least one of the core portion and the water permeable membrane. The fibrous-mass product has a grain size of 1-10 mm. The amount of moisture retained in the fibrous-mass product is adjustable between a wet state in which the core portion is saturated with moisture and an air permeable state in which the core portion is not saturated with moisture.
