Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
In a method of creping a fibrous web wherein the creping adhesive is applied to the fibrous web before it contacts the creping surface, the improvement consisting of applying a creping adhesive which comprises at least 10% by weight of the total solids content of said formulation of a polymer or copolymer having a Tg greater than 50° C.
Claim 2
Dependent Claim
59 words
In a method of creping a fibrous web wherein the creping adhesive is applied to the fibrous web before it contacts the creping surface, the improvement consisting of applying a creping adhesive which comprises at least 10% by weight of the total solids content of said formulation of a polymer or copolymer having a Tg greater than 50° C.
Claim 3
Dependent Claim
23 words
The method in accordance with claim 1 wherein the creping adhesive further comprises a polymer or copolymer having a Tg below 10° C.
Claim 4
Dependent Claim
13 words
The method in accordance with claim 1 wherein the polymer is poly(methyl methacrylate).
