Abstract
A multi-layered wet tissue product includes a first sheet layer embossed with a predetermined pattern and at a predetermined depth, and a second sheet layer embossed with a predetermined pattern and at a predetermined depth. The first and second sheet layers are thermally bonded to each other in a symmetrical structure such that an air layer can be formed between the first and second sheet layers and at least one of the first and second sheet layers is coated with liquid.
Claims14
A multi-layered wet tissue product comprising:
- a first sheet layer embossed with a predetermined pattern at a predetermined depth;
- and
- a second sheet layer embossed with a predetermined pattern at a predetermined depth,
- wherein the first and second sheet layers are thermally bonded to each other in a symmetrical structure such that an air layer can be formed between the first and second sheet layers;
- and
- at least one of the first and second sheet layers is coated with liquid.
An apparatus for manufacturing a multi-layered wet tissue product, comprising:
- an embossing roll for independently embossing first and second original sheets being continuously fed;
- a pressing roll for thermally-bonding the embossed first and second original sheets to provided a multi-layered sheet;
- a first coiler for rolling the multi-layered sheet to provide a primary multi-layered product;
- an uncoiler for releasing the primary multi-layered product and sending the released product to a next process;
- a liquid coating roll for coating liquid on the released primary multi-layered product;
- a powdering roll for applying powder on the primary multi-layered product coated with the liquid;
- a drier for drying the primary multi-layered product so that the product can contains a predetermined amount of liquid;
- a slitter for cutting the primary multi-layered product dried by the drier at a predetermined width;
- and
- a second coiler for rolling the primary multi-layered product cut at the predetermined width to provide a final multi-layered wet tissue product.
A method for manufacturing a multi-layered wet tissue product, comprising the steps of:
- independently embossing first and second original sheets being continuously fed;
- thermally-bonding the embossed first and second original sheets to provided a multi-layered sheet;
- rolling the multi-layered sheet to provide a primary multi-layered product;
- releasing the primary multi-layered product and sending the released product to a next process;
- coating liquid on the released primary multi-layered product;
- applying powder on the primary multi-layered product coated with the liquid;
- drying the primary multi-layered product so that the product can contains a predetermined amount of liquid;
- cutting the primary multi-layered product dried by the drier at a predetermined width;
- and
- rolling the primary multi-layered product cut at the predetermined width to provide a final multi-layered wet tissue product.
A wet tissue product comprising:
- a sheet layer in which liquid is absorbed, the sheet layer being formed in one or more sheets;
- and
- a powder layer formed on a side of the sheet layer.
