Abstract
A sheetlike material for adsorbing oils floating on or suspending in water and a method of producing the same, aiming at solving the problems of conventional kapok fiber sheets, such as poor adsorbency (about 10 g of an oil per gram of the sheet), difficulties in processing, inconveniences in use such as lack of nerve, etc. The method comprises mixing a kapok fiber with a bast fiber such as a jute fiber of a length of about 5 to 10 cm and further with a heat-fusible fiber for bonding, such as a polyester fiber, or mixing a kapok fiber, a bast fiber and a heat-fusible fiber, forming a sheet from the mixture, optionally subjecting the sheet to needle punching, heating, and cooling. The obtained oil-adsorbent material is free from the problem of dispersion, scattering and poor intertwinement of kapok fibers, and has a good processability and remarkably improved easiness in use, such as nerve.
