In the first part of this article basic definitions of communication apparel, describing the process of conception and its main components are introduced. Building blocks that have to be used in order to realize these generations of apparel are then mentioned and analyzed from the point of view of textiles. A classification of innovative communicative and intelligent functions attributed to communication apparel is also developed together with three different approaches to camouflage fabrics creation. In the second part of the chapter, a new development methodology of flexible textile display fabric is described. The screen matrix is produced during the weaving process, using the texture of the fabric. A small electronics device integrated into the system controls the LEDs that light groups of fibers. Each group provides light to one “pixel” on the matrix. A specific control of the matrix is then performed by wireless telecommunication services, providing instant access to the downloading of various patterns and cartoons inside the clothing. Initially developed in the field of communicative clothing, this new kind of display can also be applied to any field that requires compact and flexible devices. Moreover, it is also possible to produce large-sized displays using this technology. Various applications are to be considered, namely in the fields of personal flexible displays, camouflage fabric realization and many others.
