Fragrance and Temperature Sensitive Colours 
(Microencapsulation Approach)
Various chemical and physico-chemical techniques are used for improving aesthtic and functional properties of textiles. Application of textile finishing agents is still the primary approach for improving such properties. The last and perhaps most promising physico chemical method of applying finishing agents to textiles is microencapsulation of the agent and affixing of the microcapsuls to the fibrous substrate. An example of its utility for fabric is microencapsulation of catalyst and or durable press resins for fabrics. Another example is the diffusion of Antibacterials or pesticides from textile material laminated. 
Microencapsulation technology is increasingly being used in Japan to produce modified fabrics having novel functional properties. Microcapsules containing perfume have been attached to fabrics that release a fragrance, and cholesteric liquid. These have been microencapsulated into coated fabrics to produce swimsuits and skiwear that changes colour when the temperature rises or falls. It is probable that future developments and innovations will occur in the attachment of microcapsules to fibrous substrates to produce various improved properties. A typieal recipe for fragrance and thermo colour for dyeing and printing is given below.
Aroma Granule AG Ink for Printing 
Aroma Granule Aqvolite Ink is concentrated paste prepared by microencapsulation technology. The capsules, an rubbing with hands or scrubbing, give 18 different kinds of pleasant fragance. The capsules on pattern are durable for quite a long time, unless adverse conditions are used. They can be used on any fibrers. Aroma Granule AG Inks (Perfume Capsules), available in milky-white form, are stable for one year when stored in cool dark place.
