Problems solved by technology

However, since the blending will have a great impact on the fiber forming properties, generally the amount of added fragrance microcapsules is small, and the fragrance microcapsules embedded in the fiber are difficult to break and release fragrance.

Abstract

The invention relates to microcapsule composite cellulose nanofibers and a preparation method thereof. The microcapsule composite cellulose nanofibers comprise cellulose nanofibers and a microcapsuleloaded on the cellulose nanofibers; the mass percentage of the microcapsule in the cellulose nanofibers is 70-95 percent. The microcapsule comprises a perfume and a wall material wrapping the perfume;the wall material is a third polymer formed by heating and curing a first polymer and a second polymer; the molecular weight of the third polymer is 10000-60000. A structural formula of the third polymer is shown in a formula (II). The cellulose nano fiber with high specific strength, provided by the invention, is taken as an external support of the microcapsule and enhances the wear resistance,thereby prolonging the sustained release time and improving the slow release concentration stability of the microcapsule.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to microcapsule composite cellulose nanofibers and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's material needs are also getting higher and higher. Textile perfuming technology is an important way for textiles such as fibers and fabrics to improve product characteristics and increase added value. The effect of releasing fragrance for a long time cannot be achieved by simple fragrance soaking method, and textiles should be treated with fragrance microcapsules to make aromatic textiles have better slow-release effect and more efficacy. [0003] However, because the wall material of microcapsules has low mechanical strength and is easily broken, the controllability of the sustained-release effect of microcapsules depends on the way the microcapsules are dispersed and immobilized on the fabric. Two methods comm...
