An improved process for making sheet from a fibrous furnish includes:
depositing the furnish on a foraminous support; compactively dewatering
the furnish to form a nascent web; drying the web on a heated cylinder;
creping the web therefrom and throughdrying the web to a finished
product. The microstructure of the web is controlled so as to facilitate
throughdrying. The product exhibits a characteristic throughdrying
coefficient of from 4 to 10 when the airflow through the sheet is
characterized by a Reynolds Number of less than about 1. The novel
products of the invention are characterized by wet springback ratio,
hydraulic diameter and an internal bond strength parameter.
