PURPOSE:To obtain the subject sheet, excellent in filter performance, heat insulating properties, etc., and useful as a heat insulating material, diapers, etc., by randomly mixing two specific kinds of fibers therein and partially and thermally binding the fibers. CONSTITUTION:The objective sheet obtained by randomly mixing ultrafine fibers (e.g. a thermoplastic polymer, such as polyester or polyolefin) having 0.1-8.0mum average fiber diameter in 20-80wt.% (based on the total amount of the fibers) mixed fibers (the same fibers as those of the ultrafine fibers are used) having compatibility with the above-mentioned ultrafine fibers, >=1.5 denier and >=30mm average fiber length, partially and thermally binding the fibers according to a thermal embossing method, etc. |
