Abstract

A ring composite spinning method based on film filamentization is provided, which belongs to a textile technical field. According to the method, a film cutting drafting device is arranged above each drafting system on a ring spinning machine for cutting film material into ribbon-shaped multi-filaments to achieve the film filamentization, which changes a conventional formation of filament through linear spraying by spinneret orifices; then the multi-filaments formed pass through first and second filament drafting zones in sequence for drawing, so as to enhance and attenuate the multi-filaments. After in drawing, the multi-filaments are twisted with conventional staple fibers to form a composite yarn with high quality and functions, achieving one-step production of composite yarns of nano-micro fibers without online combination of nanofibers spinning and ring staple spinning, thereby breaking restriction of “low bulk and low-speed production of nano-spun fibers” and integrating film industry with textile industry.
