Nanotechnology processes are present into the textile field. One of these processes involves encapsulated nanoparticles or nanoproducts, know as microcapsules. Microencapsulation technology is used into textiles to confer new properties and added value. There are a lot of different active core microcapsules used in the textile industry such as durable fragrances, skin softeners, insect repellents, dyes, vitamins, antimicrobials, phase change materials, etc. The effect of microcapsules is usually measured by the presence of a property such as odour measurements when flavors are encapsulated. Neverthless, some properties such as hydration, antibacterial, insect repellents, etc., can´t be tested without analytical methods.Microcapsulated products can be applied on fabrics by impregnation, bath exhaustion, foam, spraying and coating. The most extended industrial application is by padding. Microcapsules useful life can be affected by fabrics testing and maintenance to which they are subjected during their lifetime. This work studies flavour microcapsules behaviour on plain and knitting fabrics applied by impregnation when these fabrics are subjected an abrasion test.Scanning electron microscopy (SEM) has been used in order to determinate the quantity of microencapsulated products that remains on fabrics after abrasion tests. We concluded that the abrasion resistance test destroy the microcapsules deposited on fabrics.To sum up, we can indicate that depending on the fabric structure the abrasion test result can differ from one fabric to other.
