Abstract

The invention relates to three-dimensional angle interlocking power generation fabric and a preparation method thereof. The three-dimensional angle interlocking power generation fabric is three-dimensional angle interlocking fabric formed by two yarn systems which are a warp system and a weft system, and composition yarn of the warp system and the weft system is different and is mechanical energyacquisition yarn or flexible conductive yarn; the largest power density of the three-dimensional angle interlocking power generation fabric is 48.45 mW / m<2>, the number of layers of the three-dimensional angle interlocking fabric is 2-10, the warp density is 14-18 count / 5 cm, the weft density is 12-20 count / 5 cm, and the gram weight us 0.6-1 g / cm<2>. The preparation method of the three-dimensionalangle interlocking fabric comprises steps as follows: the mechanical energy acquisition yarn and the flexible conductive yarn are taken as warp and weft and interwoven in a form of a three-dimensional angle interlocking structure, and the three-dimensional angle interlocking power generation fabric is prepared. The three-dimensional angle interlocking power generation fabric has a multi-layer structure, is easy to deform and has good power output performance, and the contact area between the warp and the weft is larger.
