  • Patent number: 5048589
    Abstract: Hand or wiper towels are made according to a process which includes the steps of: forming a furnish of cellulosic fibers; depositing the furnish on a traveling foraminous belt, thereby forming a fibrous web on top of the traveling foraminous belt; subjecting the fibrous web to non-compressive drying to remove the water from the fibrous web; and removing the dried fibrous web from the traveling foraminous belt. The dried fibrous web is not creped. These hand towels possess superior levels of absorbent capacity, absorbent rate, softness, and strength to other prior art hand or wiper towels with the same or about the same basis weight. Embossing of the hand or wiper towels enhances the superior qualities of the towels. In a preferred embodiment of the present invention, the transfer of the fibrous web from a foraminous belt of a higher speed to a foraminous belt of a lower speed produces a towel with enhanced strength and softness.
