Abstract:
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.
