Integral structure and weaving of keyboard fabric

Aiming at the special structure of fabric keyboard made of three to five layers,the idea of integral structure of fabric keyboard is put forward,and its special structural characteristics is analyzed.Insulating layer is made of interval yarns and this yarns connect the upper and lower conductive layers of the keyboard as a whole,conductive yarns form conductive points of the keyboard,so an integral structure is formed.The design methods of weave and looming drafting of the keyboard fabric are discussed.By improving warp beam let-off device,reasonal design of slaying plan,suitable parameters such as basic warp tension,shed timing,warp line,a single-shed and two-layer weave,the integral structure of keyboard fabric can be produced successfully.
