Abstract
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.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
92 words
A towel having an absorbent capacity of at least about 385%, and an absorbent rate of about 8 seconds or less, prepared by a process comprising the steps of: forming a furnish of cellulosic fibers, water, and a chemical debonder; depositing the furnish on a first 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 without creping the fibrous web.
Claim 2
Dependent Claim
92 words
A towel having an absorbent capacity of at least about 385%, and an absorbent rate of about 8 seconds or less, prepared by a process comprising the steps of: forming a furnish of cellulosic fibers, water, and a chemical debonder; depositing the furnish on a first 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 without creping the fibrous web.
Claim 3
Dependent Claim
21 words
The towel prepared by a process as in claim 1, wherein: the cellulosic fibers in the furnish comprise secondary cellulosic fibers.
Claim 4
Dependent Claim
19 words
The towel prepared by a process as in claim 2, wherein: the non-compressive drying is achieved with a through-dryer.
Claim 5
Dependent Claim
35 words
The towel prepared by a process as in claim 3, wherein: the towel has a dry tensile strength of at least about 5700 grams, and a wet tensile strength of at least about 1200 grams.
Claim 6
Dependent Claim
31 words
The towel prepared by a process as in claim 1, further comprising the step of: embossing the dried fibrous web after removing the dried fibrous web from the traveling foraminous belt.
Claim 7
Dependent Claim
21 words
The towel prepared by a process as in claim 5, wherein: the cellulosic fibers in the furnish comprise secondary cellulosic fibers.
Claim 8
Dependent Claim
19 words
The towel prepared by a process as in claim 6, wherein: the non-compressive drying is achieved with a through-dryer.
Claim 9
Dependent Claim
60 words
The towel prepared by a process as in claim 7, wherein: the towel has an absorbent capacity of at least about 400%, an absorbent rate of about 6 seconds or less, a dry tensile strength of at least about 1800 grams to about 2700 grams, and a wet tensile strength of at least about 380 grams to about 680 grams.
Claim 10
Dependent Claim
79 words
A towel prepared by a process as in claim 1, wherein: the first foraminous belt travels at a first velocity; and further comprising the step of, transferring the fibrous web from the first traveling foraminous belt to a second foraminous belt, the second foraminous belt traveling at a second velocity up to about 10% slower than the first velocity, thereby providing a series of transverse folds in the fibrous web prior to subjecting the fibrous web to non-compressive drying.
Claim 11
Dependent Claim
21 words
The towel prepared by a process as in claim 9, wherein: the cellulosic fibers in the furnish comprise secondary cellulosic fibers.
Claim 12
Dependent Claim
19 words

Claim 13
Dependent Claim
32 words
The towel prepared by a process as in claim 11, further comprising the step of: embossing the dried fibrous web after removing the dried fibrous web from the second traveling foraminous belt.
Claim 14
Dependent Claim
117 words
