Controlled delivery from textiles

Controlled or targeted release is the most common apphcation of microcapsules. Microencapsulation is an ideal tool to effect and achieve a desired delay of the active core until the correct stimulus is encountered. Most microcapsules are extraordinarily stable and show a great retardation of the encapsulated substances. Fragrances, aromas, drugs, enzymes, cosmetics and even pharmaceutical formulations (vitamins, drugs) are encapsulated for delivery from textiles at a specific time, rate, or situation. The encapsulated substances can either be released at once... 

Polymer science has been the backbone of pharmaceuticals for decades. The amalgamation of polymer science with pharmaceutical science led to a quantum leap in terms of novelty (fiexibiUty in physical state, shape, size and surface) in DDS design and development. The market for controlled-release polymer systems, which extends beyond drug delivery, is now estimated at 60 billion annually worldwide and its systems are used by over 100 million people each year. Growth of world consumption of technical textiles is expected to come primarily from nonwoven materials, especially spunlaid products, which are made from polymers rather than fibers or filament yams.
