Abstract

The invention provides a functional plant aromatic antibacterial cellulose fiber. The fiber comprises a microcapsule. The wall of the microcapsule is divided into an inner layer and an outer layer. The inner layer is made of polyacrylonitrile, and the outer layer is made of aerogel. The invention also provides a preparation method of the fiber. According to the preparation method, a plant essential oil primary aromatic microcapsule is prepared at first. The plant essential oil primary aromatic microcapsule is prepared by the following steps: adding plant essential oil into distilled water containing an emulsifier, and adopting a dual layer capsule wall, the dual layer capsule wall has the advantages that in the subsequent functional modification, the pH change will not damage the essential oil due to the dual layer capsule wall, and at the same time, the fiber has a new function. The inventor accidentally finds that the prepared fiber can store the effective components of natural plant derived fragrance. Moreover, compared with the prior art, the releasing effect of the microcapsule is better, and the releasing time is longer and more uniform.

Description

technical field [0001] The invention belongs to the technical field of functional cellulose fibers, and in particular relates to a functional plant aromatic and antibacterial cellulose fiber and a preparation method thereof. Background technique [0002] Because regenerated cellulose fiber has the characteristics of moisture absorption, good air permeability, and comfortable wearing, with the improvement of people's living standards and changes in life concepts, the functional modification of cellulose fibers has gained an unprecedented development opportunity. People hope that The existing cellulose fiber textiles have been improved in terms of smell and function, and aromatic and antibacterial fibers have emerged as the times require. [0003] Aromatic fiber is a new type of functional fiber developed in the early 1970s and rapidly developed in the mid-1980s. Scientific research shows that aroma not only has the functions of pleasing to the eye, reducing stress, eliminati...
