Patent ID: 8329223

Claim:
A method of applying a plurality of microcapsules to an outside surface of textile fibres, without the use of binders, the microcapsules not being disposed within the fibre, and the textile fibres being formed into a yarn, fabric or non-woven textile prior to application of the microcapsules, each microcapsule comprising a body having inner and outer polymer walls, the outer wall being thermoplastic for the purpose of thermal fusion onto an outside surface of textile fibres that form a textile substrate such that the microcapsule is connected to a fibre only by the points of contact of the microcapsule outer polymer wall and the fibre outer surface; and a microencapsulated material disposed within the body, the method comprising: adhering the outer wall of the microcapsules onto the outer wall of the textile fibres, manufactured as a yarn, fabric or non-woven, by heating up to at least a softening temperature, of the thermoplastic wall, wherein no film is formed between the microcapsules during the thermal fusing with the fibre and permeability of the fibre to air and vapor remains, along with both flexibility and drape of the textile fibres.
