Abstract:
1. A method of registering the extension of a knitted structure in the direction of its courses, the method comprising the steps of: providing a knitted structure of stitches arranged in courses and wales, and extendible in two dimensions defined by the courses and wales to distort the stitches, extension in the course dimension separating loops forming the stitches and extension in the wale dimension urging the loops together, wherein an electro-conductive yarn defines at least one single course in the structure adjacent non-conductive yarns, in which, when unextended in either dimension successive loops of the stitches in said at least one single course of electro-conductive yarn are in engagement in which the electro-conductive yarn defines at least one single course in the structure adjacent non-conductive yarns and has a pre-determined electrical characteristic when the knitted structure is unextended in either dimension, wherein extension of the structure in the course direction causes successive engaging loops in the stitches of the electro-conductive yarn to separate thereby breaking short circuits between them and monitoring the electrical characteristics for a change indicative of a given said extension.
