摘要：
A paper transporting felt includes a base layer, a first batt layer formed on a wet paper side surface of the base layer, a second batt layer formed on a roll side surface or a shoe side surface of the base layer, and a wet paper contacting fibrous layer formed on a wet paper side surface of the first batt layer so as to come into direct contact with a wet paper. The wet paper contacting fibrous layer is made of modified cross-section fibers.
