Abstract

The invention discloses a multilayer laundry detergent tablet, and a preparation method thereof. Each of the multilayer laundry detergent tablet comprises two layers or more than two layers of laundry detergent single tablets; an adhesive substance is arranged between the two layers of laundry detergent single tablets, or among the more than two layers of laundry detergent single tablets; and the adhesive substance is one or a mixture of a plurality of ingredients selected from a liquid bio-enzyme, a liquid perfume, a liquid softening agent, a liquid color protecting agent, and a liquid antiseptic. The preparation method comprises following steps: the surface of each laundry detergent single tablet is coated with the adhesive substance via smearing or spraying, and then two layers or more than two layers of the laundry detergent single tablets are glued together via extraction. The multilayer laundry detergent tablet is high in stability and washing capacity; deposition of insoluble substances on clothing is not caused; and the preparation method is simple.

Description

technical field [0001] This application relates to but not limited to the technical field of daily chemical washing, in particular to but not limited to a multi-layer laundry sheet and its preparation method. Background technique [0002] In my country, with the improvement of people's living standards, consumers have higher and higher requirements for washing products, especially the pursuit of convenience, high cleaning power, safety and environmental protection of washing products. As a new type of detergent, laundry tablets are favored by some consumers because of their advantages such as super concentration, quick dissolution, no hand injury, and convenient use. [0003] Although laundry tablets have many advantages, they are not ideal in terms of cleaning power that consumers are more concerned about. This is mainly due to the fact that laundry tablets do not contain washing enzymes or have poor enzyme stability. At present, most laundry tablets on the market do not c...
