Preparation and application of self-adhesive double-wall essence microcapsule

Abstract

The invention discloses a preparation method and an application method of a self-adhesive double-wall essence microcapsule. A composite emulsifier is adopted, essences are adopted as a capsule core, melamine resin and polyacrylate are used as wall materials, and the self-adhesive double-wall essence microcapsule is prepared by respectively carrying out encapsulation on the essences by respectively adopting an in-situ polymerization method and an interfacial polymerization method. The invention also provides the application method of the self-adhesive double-wall essence microcapsule. The self-adhesive double-wall essence microcapsule which is prepared by adopting the safe and environment-friendly preparation method has the solid content of 30-35 percent, which is 10-15 percent higher than that of other essence microcapsules on the market. Double-layer wall formation is carried out by adopting the in-situ polymerization method and the interfacial polymerization method, the essence encapsulation rate can reach 92-95 percent, and the self-adhesive double-wall essence microcapsule emulsion has favorable stability. The self-adhesive double-wall essence microcapsule has a self-adhesive property while keeping the peculiar advantages of the microcapsule; and a cotton fabric finishing process is simplified. In addition, the finished cotton fabric has a favorable fragrant effect which can reach 6 months after standing; and pleasant fragrance can be kept after the cotton fabric is washed for 10 times.

Description

technical field

[0001] The invention belongs to the technical field of textile finishing, and specifically relates to a self-adhesive fabric with melamine resin and polyacrylate as the double-layer wall material and essence as the core material respectively formed by in-situ polymerization and interface polymerization. Preparation and application method of essence microcapsules. Background technique

[0002] With the development of the economy and the improvement of living standards, people's requirements for textiles have undergone great changes. From the past practical type to the decoration, enjoyment, and health care type, textile perfuming conforms to this trend. Because scented textiles have the functions of antibacterial and insect repellent, covering peculiar smell, and making body and mind comfortable, they are generally liked by people.
