Referring to fig. 1, a stretch-resistant printed circuit fabric includes a fabric 1 and a wire 2 sewn to the fabric 1. The cloth 1 has a sewing state and a use state, the cloth is in a production link in the sewing state, the production link comprises sewing the electric wire 2 and other silk threads together to produce the cloth, and the cloth is in an application link in the use state, including after being made into clothes, a human body measuring instrument and the like. Since the fabric is stretchable and particularly stretchable, the electric wires 2 are often required to be distributed straight in the use state, the electric wires 2 are sewn on the fabric 1 in the sewing state in a wavy manner in order to generate a uniform voltage or at least in order not to be broken, the use state of the fabric 1 is a state after the sewing state is stretched, and the electric wires 2 are distributed straight on the fabric 1 after the fabric 1 is stretched. In an embodiment, reliable and continuous electrical connection of the product in the often stretched and contracted states can be achieved by such a wiring technique.

In various embodiments, the wiring path and the waveform amplitude may be made according to the stretch ratio of the fabric 1. When the stretching rate of the cloth 1 is large, the waveform amplitude is large, and the wiring path is not suitable to be too long; when the stretch ratio of the fabric 1 is small, the waveform amplitude is small.

In order to generate a uniform voltage or at least to prevent the wire 2 from being pulled apart in the use state of the stretch-resistant printed circuit fabric, in one embodiment, the linear distance between two ends of the wire 2 on the flat-laid fabric 1 is the end distance, and the end distance of the wire 2 in the use state of the fabric 1 is larger than the end distance in the sewing state.
