Paper towels having bulky inner layer |
摘要 |
A delaminated stratified paper towel includes a dense first layer of chemical fiber blend and a second layer of a bulky anfractuous fiber blend unitary with the first layer. The first and second layers enhance a rate of absorption and water holding capacity of the paper towel. In a preferred embodiment, the second layer is a fiber blend having a high bulk softwood fiber and a chemi-thermomechanical pulp. A method of forming a delaminated stratified web of paper towel material includes supplying a first furnish directly to a wire and supplying a second furnish of a bulky anfractuous fiber blend directly onto the first furnish disposed on the wire. Drying the first and second furnishes forms a web of paper towel material having a predetermined dryness. The web of paper towel material is thereafter creped off of the drying device and embossed to a predetermined emboss depth. The web of paper towel material has an enhanced rate of absorption and water holding capacity.
