Abstract
The present invention provides a washing product comprising two or more sheets, which comprise a water-soluble polymer and have different dissolution rates in water, wherein each sheet contains i) washing detergent components, ii) washing softening components, iii) an aromatic agent, or iv) two or more thereof. Since two or more sheets have the different dissolution rates, in the present invention, the discharge time of the washing components contained in the sheets can be controlled, thereby having an excellent washing effect.

A laundry product comprising:
- a first sheet and a second sheet having different dissolution rates, wherein the first sheet comprises a detergent component for washing and a first water-soluble polymer;
- and the second sheet comprises a softening component for washing and a second water-soluble polymer,
- wherein the first sheet and the second sheet optionally comprise a perfume, and
- wherein the second water soluble polymer dissolves in water more slowly than the first water-soluble polymer.
A method for manufacturing a laundry product comprising two or more sheets for washing having different dissolution rates, comprising:
- dissolving a first water-soluble polymer in a first solvent to prepare a first solution for a first sheet for washing;
- adding a first component for washing to the first solution for manufacturing the first sheet for washing, and mixing to prepare a first mixed solution;
- drying the first mixed solution for manufacturing the first sheet for washing with the first component for washing;
- dissolving a second water-soluble polymer in a second solvent to prepare a second solution for a second sheet for washing;
- adding a second component for washing to the second solution for manufacturing the second sheet for washing, and mixing to prepare a second mixed solution;
- drying the second mixed solution for manufacturing the second sheet for washing with the second component for washing,
- wherein the first component is a detergent component for washing and the second component is a softening component for washing.
