Abstract
Embossed fibrous structures containing a plurality of filaments and methods for making same are provided.
Claims17
An embossed multi-ply sanitary tissue product formed by embossing a multi-ply fibrous structure comprising:
- 1) a first ply of fibrous structure comprising a layer of filaments in contact with a plurality of solid additives, wherein the filaments exhibit a length of greater than or equal to 5.08 cm, wherein the filaments are selected from the group consisting of crosslinked starch filaments, crosslinked starch derivative filaments, crosslinked starch copolymer filaments and mixtures thereof, wherein the filaments account for >50 wt. % of the first ply, and 2) a second ply of fibrous structure attached to the first ply of fibrous structure by plybond glue to form the multi-ply fibrous structure;
- wherein the multi-ply fibrous structure is contacted with moisture making the multi-ply fibrous structure more easily deformable as the filaments' modulus decreases, and
- then subsequently contacting the multi-ply fibrous structure with at least one heated patterned emboss roll resulting in the filaments' modulus increasing, wherein the at least one heated patterned embossed roll comprises an emboss design such that a decorative surface comprising the emboss design is produced on a surface of the multi-ply fibrous structure to form an embossed multi-ply fibrous structure such that the emboss design is more permanent than such an emboss design imparted to the multi-ply fibrous structure without decreasing its modulus prior to imparting the emboss design and then increasing its modulus.
