|"Sprang is a method of making fabric by manipulating the parallel threads of a warp that is fixed at both ends. The manipulation can take the form of interlinking, interlacing or intertwining of adjacent threads or groups of threads (see Fig. 1). Such structures do not require the addition of any other threads to stabilized them. The work is carried out row by row at one end of the war. As an inevitable result of the warp being fixed at both ends, corresponding but contrary movements of threads appear simultaneously at the other end."
