A method of ring spinning cotton polyester blended yarn. The method is robust and can be used to manufacture the yarn even from polyester fibers that are produced from recycled materials. A new ring spun cotton polyester yarn is also provided. The yarn has few defects and can be effectively dyed when woven into cloth.

A method of producing at least one yarn formed by spinning at least two individual fibers, comprising the following steps: providing at least two individual fibers, to be spun to form the at least one yarn to be produced, feeding the at least two provided fibers to a spinning device comprising at least one spindle element or bobbin element via a guide device comprising a plurality of, in particular cylinder-like or cylindrical, guide elements, spinning the fed fibers in the spinning device, forming the at least one yarn to be produced, wherein the at least two fibers are fed to the spinning device via at least two separate, in particular cylinder-like or cylindrical, guide elements that are arranged such that they are spatially separated from one another in at least one spatial direction.

A method to form yarn via film fiberizing spinning belongs to a textile technical field. A film cutting device is arranged behind each drafting system on a ring frame, whose cut resistance apron and cutting roller engage with each other to form a cutting zone to cut and fiberize the film to get belt-like multi-filaments. Then the multi-filament formed passes through the first, second and third drafting zones in sequence for drawing, in such a manner that the multi-filament molecular orientation and crystallization are improved. After being drafted, the multi-filaments are twisted into yarn by ring spinning, which provides a novel high-efficient and short-processing way of producing yarns of nano-micro fibers using films instead of conventional nano-spun fibers such as electro- and centrifugal spun fibers, thereby breaking restriction of low bulk and low-speed production of nano-spun fibers and integrating the film industry with the textile industry.

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.
