Abstract

The invention provides preparation and application of a long-acting high-affinity softener prepared from essence microcapsules. The long-acting high-affinity essence microcapsule softener is prepared in the following steps: preparing a compound dispersant by using a nonionic surfactant and amphiphilic macromolecules, and preparing the essence microcapsules by taking essence as a core material and taking etherified melamine resin as a wall material; and preparing a fragrant microcapsule softener by taking the essence microcapsules as a raw material. The invention further provides an application method of the long-acting high-affinity fragrant microcapsule softener. The essence microcapsules prepared by a simple, convenient and environment-friendly method can be suitable for softeners, laundry detergents and the like of various ionic systems, the essence content can be 20-30 percent, and the solid content can be 22-35 percent. Compared with other commercially-available essence microcapsule, the solid content of the essence microcapsules can be 10-15 percent higher than that of the commercially available essence microcapsule products, the essence coating rate can be 60-70 percent, and the stability is good. Meanwhile, the long-acting high-affinity fragrant microcapsule softener prepared by taking the essence microcapsules as a raw material is good in the perfuming effect on fabrics and long in fragrance lasting time on fabrics, the fragrance can last for six months in a standing state, and high fragrance explosive power can be achieved by rubbing.

Description

technical field [0001] The invention belongs to the technical field of textile finishing, and specifically relates to a composite dispersant prepared from nonionic surfactants and amphiphilic macromolecules, with essence as the core material and etherified melamine resin as the wall material, which is prepared by an interfacial polymerization method The preparation and application method of the softener using long-acting high-affinity essence microcapsules can be adapted to softeners and laundry detergents of various ionic systems. Background technique [0002] Microcapsule technology refers to the technology of using natural or synthetic polymer materials to coat the target object with chemical or physical methods to form tiny particles with a core-shell structure with a diameter of 0.1-1000 μm. Microcapsules have the functions of protecting substances from environmental influences, reducing toxicity, masking bad taste, controlling core release, prolonging storage period, c...
