Laundry composition and preparation method therefor

SOLUTION: A laundry composition comprises an encapsulation material, a functional component encapsulated within the encapsulation material, and a binder used for bonding the encapsulation material, wherein the encapsulation material is a film-forming material having a washing function, and the functional component comprises one or more of softening particles, fragrance-retaining particles, active oxygen particles, and an enzyme preparation.EFFECT: By encapsulating the functional component with the encapsulation material having the washing function, the laundry composition can simultaneously achieve a cleaning and stain removal function, a softening function, and a fragrance-retaining function. In addition, since the softening particles, the fragrance-retaining particles, the active oxygen particles, and the enzyme preparation in the functional component are not directly added to the encapsulation material, it is possible to prevent the functional component from losing effectiveness when the encapsulation material is subjected to high-temperature press-forming, thereby solving a problem that effects are poor or costs are high when functional components are directly added to conventional laundry sheets.SELECTED DRAWING: Figure 1
