Laundry sheet comprising functional granules
The present invention provides a laundry sheet wherein one or more component selected from a group consisting of a builder, an enzyme, a bleaching agent and a bleach activator is contained as a granule in a laundry film prepared using a laundry detergent component and a film-forming water-soluble polymer. The laundry sheet of the present invention completely dissolves in water and thus does not need to be removed after laundering. In addition, the laundry sheet of the present invention has superior cleaning performance, is convenient to use and has superior storage stability.
1. A laundry sheet comprising:
an active component for laundering, wherein the active component is an enzyme, and
a laundry film formed by mixing a laundry detergent component and a film-forming water-soluble polymer, wherein the laundry detergent component is sodium lauryl sulfate,
wherein the active component for laundering is a granule, and the granule is contained and distributed between polymer matrices on at least one side of the laundry film,
wherein the granules are added after the mixing of the laundry detergent component and the film-forming water-soluble polymer,
wherein the granule is an assemblage of an amorphous particle,
wherein the film-forming water-soluble polymer is polyvinyl alcohol having an average degree of polymerization of 100-3000, and
wherein the granule has an average particle diameter of 0.5 mm to 2 mm.
2. The laundry sheet according to claim 1 , wherein the enzyme is one or more selected from a group consisting of a protein-degrading enzyme, a lipid-degrading enzyme, a carbohydrate-degrading enzyme, a cellulose-degrading enzyme, a mannan-degrading enzyme and a pectin-degrading enzyme.
3. The laundry sheet according to claim 1 , wherein the laundry film is stacked to form a multi-layered structure.
