SINGLE-LAYER OR MULTILAYER NONWOVEN FABRIC OF LONG POLYESTER FIBERS, AND FILTER COMPRISING SAME FOR FOOD

摘要

Provided are: single-layer or multilayer nonwoven fabric of long polyester fibers which is excellent in terms of transparency, dimensional stability, powder leakage property, and component extraction property; and a filter for foods which comprises the nonwoven fabric. The single-layer or multilayer nonwoven fabric of long polyester fibers according to the present invention has a content of inorganic particles of 0-100 ppm and a 10%-cumulation pore diameter less than 1,000 µm, the difference between the 10%-cumulation pore diameter and the 2.3%-cumulation pore diameter being 500 or less, and has a basis weight of 10-30 g/m2.
