摘要：为避免囊壳原料对环境造成危害，选择可降解的乙基纤维素（EC）为壁材，通过溶剂蒸发法制备了薰衣
草精油微胶囊。结果表明，搅拌速率对微胶囊粒径和表面微孔有较大影响，当搅拌速率为 1200 r/min，EC 和精
油质量分别为 1.0 和 1.5 g 时，微胶囊中值粒径为 70.8 μm，包封率为 44.3%。通过湿法涂层工艺将制备的精油微
胶囊用于吸湿透气型涂层织物的制备。SEM 表征表明，该方法保留了棉针织物的原形貌。30 d 的释放后仍具有
39.2%的香味保留率，这得益于胶囊化后精油中乙酸芳樟酯质量分数提高了 27.09%，使精油的储存期延长。拉
伸-涂层织物表面微胶囊分布均匀、黏覆量多，香味数值可高达 382。拉伸和未拉伸制备的涂层织物均具有 600 mm/s
以上的透气率，水洗 5 次香气保留率在 35%以上，摩擦 50 次后涂层织物质量保持在 96%以上。这种涂层织物的
制备方法简单，可以有效改善涂层织物透气性和牢度无法兼具的问题。

Abstract: In order to avoid the harmful impact of capsule raw materials to environment, microcapsules
containing lavender essential oil were prepared by solvent evaporation using degradable ethyl cellulose
ether (EC) as wall material. The results showed that the stirring rate had a great influence on the particle
size and surface micropores of the microcapsules. When the stirring rate was 1200 r/min and the mass of
EC and essential oil were 1.0 and 1.5 g, respectively, the median particle size of the microcapsules was 70.8
μm and the embedding rate was 44.3%. Then, the microcapsules were used for preparation of hygroscopic
and breathable coated fabrics through wet coating process. SEM results showed that this method retained
the original shape of the cotton knitted fabric. The fragrance retention rate after 30 days of release was still
maintained at 39.2%, which was attributed to the mass fraction of linalyl acetate increased by 27.09% in the
encapsulated essential oil prolonging the storage life of the essential oil. The microcapsules were found to
be uniformly and massively distributed on the surface of the stretched coated fabric, making the fragrance
value as high as 382. The air permeability of the stretched and un-stretched coated fabrics was more than
600 mm/s, the fragrance retention rate was more than 35% after being washed for 5 times, and the quality
remained >96% after being rubbed for 50 times. The preparation method of the coated fabric is simple and
can effectively improve the “trade-off” between air permeability and fastness.
