Abstract

The invention discloses a multifilament unfolding non-equal convergence double-wrapping composite structure yarn device, a using method and application. The multi-filament unfolding non-equal convergence double-wrapping composite structure yarn device comprises a base frame, a yarn guiding device and a yarn guiding device, the first tension mechanism is arranged on the base frame and is used for adjusting the tension of the multifilament entering the tension mechanism; the first filament spreading mechanism is arranged on the base frame, and the filament spreading mechanism is used for carrying out filament spreading operation on the multifilament located on the filament spreading mechanism; the first limiting mechanism is arranged on the base frame, and the limiting mechanism is used for adjusting the wrap angle between the multifilament and the filament spreading mechanism; the first driving mechanism assembly is arranged on the base frame; the invention discloses a first controllable-spacing roving guiding and feeding mechanism. According to the invention, multifilament separation and dispersion effects based on the binary tree model are realized through the herringbone dotted protruding structures, and large-range adjustment and fixed-width control of the expansion width are obtained by combining the maximum wrap angle.
