Core–shell nanocapsules containing essential oil for textile application

Abstract

A novel polysiloxane-modified aromatic nanocapsule with hard core and soft shell has been prepared by two-stage emulsion polymerization method. The core of the nanocapsule is made up of styrene/methyl methacrylate copolymer, while the shell is poly(butyl acrylate) modified by octamethylcyclotetrasiloxane. Scanning electron microscopy and transmission electron microscope images reveal well-defined core-shell morphology of the particles, and the average particle size is about 100 nm. Ultraviolet-visible analysis shows that the essential oil can be well encapsulated by the nanocapsules and the encapsulation efficiency and loading capacity are 78.76% and 26.25%, respectively. The residual rate of essential oil is about 25.3% after being washed 15 times, which indicates that the nanocapsules have excellent washing durability. These core-shell aromatic nanocapsules show great potential application in fabrics treatment.

Towards the Sustainability of the Plastic Industry through Biopolymers: Properties and Potential Applications to the Textiles World

“…They act as catalysts, accelerating chemical reactions in highly specific and efficient ways while not altering or being consumed [121]. Different enzymes are already used in experiments for the textile industry, and they are able to impart specific functional features to treated textiles: chitosan [103], cyclodextrin [123], alginate [124], or plant-based bioactive materials (aloe vera) [125], essential oils (jasmine) [126], natural dyes extracted from different parts of plants such as bark, leaf, root, and flowers containing common coloring materials such as tannin, flavonoids, and quinonoids [127].…”

An overview of microencapsulation technology in the application of aroma and antibacterial finishes

“…Bhatt,et.al (2018), studied the application of lemongrass oil on fabric by two methods: oil microcapsules applied through padding and exhaust method. Lemongrass oil microcapsules were prepared using complex coacervation technique and applied on fabric using pad dry cure technique [24] . Valdes (2018), has discussed the main techniques and the different mechanisms based on the different properties and the development and application of microencapsulation.…”

“…The structure and properties of the Nano capsule can be studied by using the Transmission Electron Microscope (TEM), Dynamic Light Scattering (DLS), Gas Chromatography etc.Ultraviolet-visible analysis may be done to study the encapsulation efficiency and loading capacity Liu (2017).The properties and the effect of the aroma finishing on the physical properties of the fabric such as the surface morphology can be studied by Scanning electron microscopy (SEM)), thermal properties measured by Simultaneous Thermal Analysis (STA), thermo gravimetric analysis,size and size distribution by SEM and ImageJ software, and release behavior of the microcapsules can also be analyzed. SEM may be used to examine the treated fabrics before and after washing and Fourier transform infrared spectroscopy (FTIR) to confirm the covalent attachment of the produced microcapsules to the cotton fabrics.…”

Performance of Cotton, Cotton-Polyester, and Polyester-Elastane Fabrics Impregnated with Ultrafine Polymeric Nanoparticles Loaded with Lavender Oil

“…Within a great framework of possibilities, the preparation of fabrics that emit aromas even after a long time of use is a current research topic. The use of micro and nanocapsules containing essences and essential oils for impregnating fabrics has been widely reported in the specialized literature [5][6][7][8][9][10][11][12][13].…”
