摘要

Economical efficiency and environmental protection are key elements of modern textile treatment, where chemical fluids are digitally assigned to designated places in a printing like process. Except arbitrarily designed colour patterns, technology provides the ability to add individual functionalities not achievable in the classical approach i.e. dip dyeing based processes. The precise deposition of chemicals or bonding components like microelectronic chips on a material substrate is crucial in producing multilayered fabrics. This paper demonstrates an optical monitoring system which enables the precise control of the deposition of functional materials or components on fabric. The optical system consists of a set of Fibre Optic Image Bundles (FOIB) connected to a single CCD line camera which enables the correlation in space and time of images acquired from different parts of the area Monitored. During the deposition process the system measures fabric surface deformation and detects motion instability, and then adjusts the printing parameters accordingly.
